Why Eskimos Don't Overdose on Vitamin D. Overdose of Vitamin D3

An overdose of vitamin D is, generally speaking, not a very frequent phenomenon, although today, when overly caring parents want to “fortify” their children as much as possible, this topic is becoming more and more relevant. However, there is good news here - vitamin D in all forms is fat-soluble and even when consumed in excess, it is simply deposited in adipose tissue in reserve. Due to this, for example, its reserves, accumulated by the body during the summer in people living in high latitudes (for example, in Russia), can be spent all winter.

An overdose of vitamin D (cholecalciferol) usually occurs with excessive use of the appropriate vitamin preparations, when the body cannot cope with the distribution and consumption of the beneficial substance in general.

Especially often there is an overdose of vitamin D in infants. The reasons for this are the excessive anxiety of parents who give the child increased amounts of the vitamin, and the specificity of the child's body in general: it still does not know how to cope with increased amounts of cholecalciferol.

On a note

An excess of vitamin D, leading to symptoms of hypervitaminosis, rarely develops due to a single dose, even a very large one. In the vast majority of cases, an overdose of this substance develops gradually with chronic abuse of drugs containing it. Sometimes it takes months of improper intake of appropriate drugs for the symptoms of vitamin D hypervitaminosis to appear.

Why is too much vitamin D dangerous?



In the long term, chronic overabundance of vitamin D can lead to very serious pathologies:

  • osteoporosis and bone demineralization
  • resorption of the stroma of the bone marrow
  • blockage of blood vessels and valves of the cardiovascular system by mucopolysaccharides, their hardening, the development of atherosclerosis
  • increased deposition of calcium salts in internal organs
  • polyuria
  • arthralgia.

In children with a constant excess of vitamin D, asthenia develops, there may be disturbances in the development of the skeleton associated with an excess of the rate of bone growth over the rate of strengthening the joints and the muscular corset. For this reason, scoliosis, lordosis, kyphosis can develop, dislocations and fractures become more frequent, and excessive growth appears.

However, at first, an excess of vitamin D is characterized by temporary specific disorders, according to which it can be quickly calculated and measures taken in time, preventing the situation from aggravating.

Symptoms of hypervitaminosis

When taking several ultra-high doses of vitamin D or starting a reaction to its chronic overdose, characteristic symptoms develop:

  • digestive disorders - nausea, vomiting, diarrhea or, conversely, constipation, loss of appetite
  • shortness of breath, shortness of breath
  • fever
  • muscle pain, pain in the head and joints
  • convulsions
  • increase in blood pressure.

It is these symptoms of an overdose of vitamin D that occur in the first place. They also pass quickly enough when you stop taking the drugs or normalize their number.

Features of an overdose of vitamin D in infants

The specificity of an overdose of vitamin D in infants is that in addition to the symptoms characteristic of it, a child can often have an individual reaction. If the baby has other somatic diseases, hypervitaminosis can cause a deterioration in his condition and aggravate symptoms.

In the general case, the symptoms of an overdose of vitamin D in infants and children up to a year are as follows:

  • Sleep disturbances, which is especially well manifested if the child has already developed a night sleep regimen. With hypervitaminosis D, the child becomes more restless, often cries at night, falls asleep longer, even if he wants to sleep.
  • Hair growth slowdown.
  • Vomiting, frequent regurgitation.
  • Increased excretion of urine, thirst.
  • Violation of the regime of defecation.

Most often, an overdose of vitamin D in infants occurs due to carelessness of parents. Vitamin preparations for infants are designed to take 1 drop per day. Two drops will already be an excessive dose, and three - may well cause hypervitaminosis with constant use.

It is very easy to make a mistake when dosing at home. It is even easier to calculate that “a little more is not scary” and consciously give the child excess amounts of the vitamin.

On a note

An overdose of vitamin D in infants is also a common occurrence because, due to the small amount of adipose tissue, the child's body simply has nowhere to put excess cholecalciferol. The normal dose for a newborn is 75% of the norm for an adult, despite the fact that the body weight of the child is 10-15 times less. 1 drop of the same Aquadetrim fully provides an adult with vitamin D, and therefore for a small child, even small fluctuations in the amount of vitamin entering the body can be critical.

“We were on breastfeeding, in the second month the doctor prescribed vitamin D in prophylactic doses. At three months, it turned out that I did not have enough milk, and they began to add the mixture. Accordingly, instead of a prophylactic dose, the doctor has already prescribed the usual treatment, although the daughter had no signs of rickets, and D3 was part of the mixture. And then it started: because of the bald back of the head - one more drop more per day, after ARVI - they generally prescribed 5 drops of Aquadetrim per day. I just read the normal instructions and was horrified, but then I didn’t even think about it. The little one began to sleep poorly, she has constant thirst, pimples under her armpits. The pediatrician looked - and again said that the matter was in vitamin D and it was not enough. Fortunately, a friend of the infectious disease specialist pulled me up in time and said that without signs of rickets, a child should not drink more than 1 drop a day. Then I just found out that all the troubles are not due to a lack, but due to an excess of the vitamin. Nightmare, I was ready to kill the doctor ... "

Amounts of vitamin D sufficient for an overdose

The normal amount of vitamin D for an adult is 400-600 IU per day (10-15 mcg per day), depending on body weight and physiological state. The maximum amount of 600 IU is prescribed for the treatment of certain diseases and for short-term use by pregnant women.

The need for vitamin D in an infant is 300-400 IU per day (7.5-10 mcg).

Insignificant (one and a half times) one-time intermittent excess of these quantities will not lead to the development of an overdose. Larger doses can already cause mild manifestations of hypervitaminosis, usually limited to digestive disorders.

On a note

It should be remembered that a significant amount of vitamin D is produced in a person of any age in the skin under the influence of sunlight (on a summer day on the street - the full daily rate). Adding to this number of additional doses, even prophylactic ones, can already lead to an overdose.

Serious overdoses of vitamin D occur with regular use of more than 2,000 IU or with a single dose of 10,000 - 15,000 IU.

On a note

1 drop of Aquadetrim or Vitamin D-Teva contains 600 IU of the vitamin - the full daily allowance. For a single overdose, it is enough to use 15-18 drops, and for the development of chronic hypervitaminosis - 3-4 drops daily.

How to avoid an overdose?

Avoiding an overdose of vitamin D is easy. It is important to remember that in the absence of obvious signs of rickets and symptoms of hypovitaminosis, you should not use it. You can add vitamin-rich foods to your diet and be in the sun as often as possible, exposing exposed areas of your body to it.

In winter, for a healthy adult and child, it will be justified to use a daily dose of a vitamin as a prevention of hypovitaminosis. But more than 400 IU per day can be taken only in the following cases:

  • as directed by a doctor, preferably with confirmation of the need for admission by several more specialists;
  • in the presence of obvious health problems, the doctor should already figure out whether vitamin D will help in these cases;
  • in the absence of the ability to consume vitamin D with food.

It should be remembered that in many cases the cause of an overdose of vitamin D is self-medication. Even if the patient does not trust a particular doctor, it is wiser to seek advice from several specialists and act on the results of their consultations than to prescribe treatment on your own. In any case, when taking vitamin D, you should carefully monitor your body and well-being, and in the presence of any severe disorders, reduce dosages or even stop taking the vitamin for a while.

The benefits and harms of vitamin D: should it be given to children

Vitamins are chemical substances of organic origin that are absolutely necessary for our body. With a lack of vitamins, metabolism is disturbed, which affects the functioning of organs and the well-being of a person. Some vitamins are part of the enzymes involved in biochemical reactions, some become enzymes themselves or catalyze these reactions. Among the vitamins there are also substances from which hormones are subsequently formed.

Vitamin status, as of 2012, has been assigned to 13 compounds and two more are under review. It is important to know about vitamins that they almost do not tolerate cooking, frying and other methods of cooking, which is why the most vitamins are in food that is consumed fresh - for example, in fruits and vegetables.

Water soluble and fat soluble vitamins

Vitamins are divided into 2 large groups - water-soluble and fat-soluble vitamins. The first includes vitamins of group B, vitamin C and P. The second includes four compounds - vitamins A, D, E, K. The diet should contain vitamins of both groups. Fat-soluble vitamins can be stored in the body, stored in reserve in the liver and adipose tissue, and are well absorbed in the company of fats. Water-soluble vitamins in excess are simply excreted from the body. They don't need fat to digest. Interestingly, scientists have long synthesized water-soluble analogues of fat-soluble vitamins.

Vitamin D is a fat-soluble vitamin. Partially, it is produced, more precisely, it is activated in melanocytes of the skin cells under the action of sunlight. Such vitamin D is called endogenous (endo means "inside"). In countries where there are few sunny days, including Russia, vitamin D does not have time to be synthesized in the skin in sufficient quantities, and its only source remains food or capsules and tablets. By the way, in people with black skin, due to the large amount of pigment in the skin, this vitamin is also poorly produced.

Vitamin D is needed to strengthen bones and reduce the risk of osteoporosis. He, like a key, opens the cells of the bones so that calcium can penetrate inside, which, among other things, is necessary for better healing of bone injuries. Vitamin D increases the absorption of calcium and phosphorus in the intestines, maintaining normal levels of these compounds in the body, which are necessary for bone health.

As recent studies have shown, vitamin D has another extremely important function. There is a disease related to a number of autoimmune. In autoimmune diseases, immune cells "attack" the cells of the body itself, considering them foreign. If the autoimmune process affects the myelin sheaths of the nerves, a serious illness develops - multiple sclerosis. So, it has been found that vitamin D is able to bind with autoimmune cells, making them more “peaceful” and protecting our brain and nerves from multiple sclerosis. In addition, it is necessary for the prevention of diabetes, Alzheimer's disease, Parkinson's disease, heart and vascular diseases, and even malignant tumors.

Vitamin D is a precursor and stimulates the formation of testosterone - the main male sex hormone. Without this vitamin, a man will not be able to build muscle and look like a sort of macho, and he also develops problems in the sexual sphere. Therefore, today, if a man is found to have low testosterone, treatment is unthinkable without vitamin D supplements. However, women need vitamin D no less, since it is involved in reproductive function.

Vitamin D is good for vision. It prevents the development of the so-called macular degeneration of the retina - a disease that often ends in blindness. Vitamin D also affects teeth. It has been established that with its deficiency, tooth enamel becomes loose and vulnerable to damage by bacteria. It follows that if there is little vitamin D, then there will be many visits to the dentist. Finally, vitamin D ensures normal blood clotting and contributes to the functioning of the thyroid gland. When applied externally, it helps with psoriasis.

The daily intake of vitamin D for children from 5 to 13 years old and adults is 2.5-5 mcg, during pregnancy and in the first 5 years of life it needs more - up to 10 mcg. There are foods that contain record levels of vitamin D. For example, three eggs contain enough vitamin D to cover the daily requirement. 100 grams of tuna contains as many as three daily allowances. In one bank of cod liver - one and a half daily norms.

In addition, vitamin D is found in cheese, milk, fatty fish. By supplementing your diet with these foods, you can prevent hypovitaminosis. An excellent source of vitamin D is fish oil, which today comes in the form of capsules, and not the nasty substance that we were fed as children. To increase the endogenous production of vitamin D, you can do ultraviolet baths at home using a special lamp.

Vitamin D deficiency: rickets, arthrosis, immunity

The norm of vitamin D in the blood is 30-100 ng / ml. Vitamin D deficiency is found in many people. It is most pronounced in young children, who develop rickets with a lack of vitamin D. With rickets, the fontanel closes late in a child, teeth begin to erupt later, bones soften, which causes deformation of the skull, pelvis, chest (chicken breast), curvature of the legs like the letter “O” and thickening of the joints. Signs of rickets are also excessive sweating, irritability, poor sleep. If hypovitaminosis is dealt with in time, many symptoms of rickets go away, but some, say, chicken breasts, can persist for life, reminding that this person had rickets in childhood.

Vitamin D deficiency is also harmful for adults. As already mentioned, a lack of vitamin D makes us vulnerable to autoimmune diseases, including multiple sclerosis, arthrosis, and rheumatoid arthritis. In men, it causes a lack of testosterone and infertility. With a lack of vitamin D, calcium is washed out of the bones and hyperparathyroidism develops, in which calcium loss only intensifies. Bones become brittle, brittle, which increases the risk of fractures in a fall or other injury. Signs of vitamin D deficiency include loss of appetite, burning sensation in the mouth, weight loss, decreased visual acuity, and insomnia. All these violations are easily eliminated when taking vitamin D in capsules or tablets.

Meanwhile, not only a deficiency, but also an excess of vitamin D is not useful for the body. It leads to calcium retention in the body and its deposition in organs and tissues, which interferes with their function. Excess calcium also disrupts the functioning of the heart and nervous system.

With a slight hypervitaminosis, loss of appetite, irritability, poor sleep, thirst and increased urine output, constipation, joint pain, and muscle pain are noted. As hypervitaminosis worsens, vomiting, palpitations, a decrease in the activity of the alkaline phosphatase enzyme, an increase in the level of salts of phosphoric, citric acid, cholesterol and proteins in the blood are added to these symptoms.

In severe poisoning, vomiting becomes frequent, weight loss is significant, dehydration develops, convulsions, shortness of breath, arrhythmias, a decrease in the concentration of magnesium in the blood, infections caused by bacteria often occur. In some cases, depression of the nervous system to coma is possible. With hypervitaminosis D, calcium excretion agents, liquid paraffin, vitamins E and A, and other drugs are used.

Thus, troubles lie in wait for us not only with a shortage, but also with an excess of vitamin D, and for coordinated work the body needs a certain amount of it. You can determine the level of this substance in the blood using a special analysis. And knowing the norms of the vitamin, any person can independently regulate its intake into his body by changing the diet or taking pharmacy vitamin D.

And the substances that our body needs for its proper functioning. It is important to get the prescribed daily dose of this substance in order not to suffer from its deficiency later. How much calciferol does a person need per day? It is enough for adults to receive from three hundred to six hundred IU, and for children under twelve years old it is necessary from four hundred to five hundred IU. From infancy, babies are saturated with vitamin D through mother's milk, and it is also important to walk with the child in the sun, because calciferol, in addition to food, enters our body through the sun's rays. Calciferol deficiency already at an early age threatens such a serious and dangerous disease as rickets.

But this does not mean at all that you need to oversaturate the body with this substance, because otherwise hypervitaminosis of vitamin D may occur, which is no less dangerous than its deficiency. In this article, we will look at the reasons why this phenomenon may occur and the symptoms that you should pay close attention to. And also talk about methods of treatment and prevention.

Why does an overdose occur?

Above, we wrote the allowable daily allowance of calciferol, an excess occurs from exceeding this norm. How is it possible to overdose?

  • It may arise if you are taking calcium supplements while also taking "ultraviolet baths" and fish oil to strengthen the immune system in this way. But remember that everything is good in moderation.
  • If you have been taking the drug for about six months, three to five drops, you may also experience an overdose of vitamin D.
  • Alcohol solution in large doses also provokes a state of acute hypervitaminosis. We are talking about a period of three to four weeks, at a dosage of ten to twenty drops.
  • For an excess of this substance hypersensitivity to this element can affect, and this can happen when using a small dose.
  • Remember what to consider and individual intolerance to the drug, because the symptoms will be similar to hypervitaminosis.

It is important to understand that taking any drug is highly discouraged without the supervision and control of a doctor, even taking a seemingly harmless vitamin D. But without the recommendations of a specialist, you can easily overdo it with the dosage, initially determining it for yourself incorrectly. Do not think that if nothing happened after two or three times of taking the drug, then everything is under control, it is not. Calciferol has a cumulative property, so the symptoms appear with prolonged use of the drug, the period can even be six months. In order not to eliminate the consequences of uncontrolled use of the drug, it is better to discuss the dosage with your doctor, for each person it will be individual.

About symptoms

An overdose of calciferol, as it can be both acute and chronic. It is acute in children up to the age of six months, it is enough to use the drug for two to three weeks, and this also applies to people who are hypersensitive to the components of this substance. Symptoms of acute hypervitaminosis manifest differently in adults and children.

Infants may suffer from hypervitaminosis due to parental inattention in observing doses, as well as due to thin adipose tissue, where excess matter accumulates. So what are the symptoms to watch out for?

  1. The baby's sleep is disturbed he will fall asleep for a long time, while often crying at night.
  2. He will vomit often vomiting may also be added.
  3. Hair will grow more slowly.
  4. The child will often want to drink, at the same time, urine will begin to stand out in large sizes.
  5. In addition to sleep, appetite will also worsen, it will be reduced.
  6. The newborn may suffer from cramps and constipation.
  7. Lethargy, weakness and apathy will appear.
  8. The color of the skin takes on a grayish-yellow tint, becomes dry.
  9. The baby is losing weight.
  10. Bone tissue becomes dense.

In older children, the symptoms largely coincide with adults, but there are also individual signs, some of which are extremely dangerous to health:

  • The child is losing weight.
  • The skin becomes less elastic.
  • The body temperature rises.
  • There is a spasm and cramp in the muscles.
  • There is an increase in the liver and spleen.
  • There is a slowdown in the pulse.
  • And two more serious violations, which can lead to serious consequences. If calcium is deposited in the cornea, it threatens with blindness, and if in the heart, then death can occur.

The well-known pediatrician Evgeny Olegovich Komarovsky in his program answered the question of how not to cause an overdose of calciferol at an early age of the baby. To avoid rickets, while maintaining a normal level of vitamin D in the body, you just need to walk with the child in the sun, with enough of its rays on the face and hands. With walks, too, you should not overdo it, in total they should be no more than two hours a week.

As for adults, here you should pay attention to the following signs that indicate an overdose of the drug:

  1. The process of digestion is disturbed.
  2. There is nausea and vomiting.
  3. Urine is excreted frequently and is cloudy.
  4. There is hypertension.
  5. There may be toothache.
  6. There is lethargy in the joints, drowsiness.
  7. The eyes are inflamed.
  8. Cholesterol rises.
  9. It becomes difficult to breathe.
  10. You can even lose consciousness.

Chronic intoxication is characterized by: muscle pain, sleep disturbance, weakness and regular fatigue, stool disturbance, lower back pain, urination disorders, muscle spasms, weight loss, weakened immunity.

About the methods of treatment

So we talked about what is an overdose of vitamin D in infants, older children and adults, why it occurs, and what are the signs of this. It is important to understand how to treat this problem. Firstly, it is worth noting that the treatment is carried out only under the supervision of a doctor, self-medication is unacceptable here. At the first signs of intoxication of the body, immediately seek help from a specialist. Immediately you will need to exclude from the diet some foods that contain more vitamin D3. We are talking about cottage cheese, milk, chicken eggs and fish oil. Of course, treatment will not do without special additional therapy, in which vitamins B and C are prescribed.

Sometimes there is hospitalization where doctors inject a solution of sodium chloride with glucose to restore lost fluid and reduce intoxication of the body. In addition, antibiotics are prescribed to prevent bacterial infection. Various drugs are also prescribed to eliminate disorders in the heart, blood vessels, and kidneys.

It is important to start treatment immediately otherwise, an overdose threatens you with kidney failure, atherosclerosis, thyroid damage and other dangerous diseases. All these are very serious consequences that can be avoided with the timely help of a doctor. If you have been taking vitamin D for a short time in the wrong doses, then after stopping this drug or reducing the dosage, the symptoms will go away on their own without any medical intervention.

A few words about prevention

As we said above, be sure to consult a specialist before taking this or that drug containing, you can also get acquainted with it in general.

The important point is that it should be taken only in case of an acute deficiency, if there is none, then it will be enough to be in the sun more often and eat the right food rich in vitamin D.

We are talking about meat, fish, dairy products, mushrooms, butter, eggs (especially yolks). This rule applies to both adults and children. Sometimes taking this drug is necessary in the winter, when there is little solar heat outside. But this also requires a doctor's recommendation, never self-medicate yourself, and even more so your child. At the first signs of hypervitaminosis, the drug is canceled or prescribed in a lower dosage.

Always remember that this is your health and it is important to take it seriously, not allowing yourself to take certain drugs. An experienced doctor will always be able to help you in these matters and at the same time avoid unpleasant consequences. Be healthy!

Vitamin D3 is a substance that is both a hormone and, as it is called, the “sunshine vitamin”. There are two types of this substance:

  • natural - it is included in the composition of products of animal origin;
  • synthetic - formed under the influence of sunlight, is part of various food additives.

There are several more forms of this substance - D 4, D 5 and D 6. These groups are the precursors of D3, they do not have such high biological activity, they are used in medicine as an antitumor agent.

A person is not immune from vitamin D3 deficiency at any age. With insufficient consumption of it, various health troubles appear. Despite the undeniable benefits, you should know that an overdose of vitamin D3 can lead to the most serious consequences. Hypervitaminosis is an overdose that requires immediate medical attention.

Symptoms of an overdose of vitamin D3 are due to the severity of poisoning, in adults this process proceeds a little differently than in children.

How much and why you need to take vitamin D3

The drug D3 is used for both therapeutic and prophylactic purposes. Why is he appointed? To prevent rickets, doctors recommend it to children from the first days of life, especially babies born in the autumn-winter period, when there is little sun. As a therapeutic drug for adults and children, it is prescribed in the following cases:

  • with the development of rickets;
  • with increased fragility of bones and their prolonged fusion;
  • with a low level of calcium and phosphorus in the body;
  • with inflammation of the bone marrow;
  • with tuberculosis;
  • with lupus erythematosus.

What is vitamin D3 for? Deficiency, like an overdose of vitamin D, can cause serious harm to health. The scope of this substance includes:

  • protein synthesis;
  • normalization of skeletal growth;
  • saturation of teeth, bone tissue with minerals;
  • strengthening muscle tissue;
  • raising the body's defenses.

The daily dose of vitamin D for adults and adolescents is 10 mcg, for children from 4 years old - 2.5 -3 mcg, up to 4 years - 8 - 10 mcg. Symptoms of vitamin D poisoning are observed after taking 15 mcg or more of the substance daily. Usually the dose is determined by age, lifestyle, climatic and environmental conditions and individual characteristics of the organism. Depending on a number of factors, the dosage may be increased, this applies to people:

  • living in the Far North or in ecologically unfavorable areas;
  • having diseases of the kidneys and organs of the gastrointestinal tract;
  • pregnant and lactating women;
  • undergoing long-term treatment in a hospital.

Vitamin D overdose is not common because it is a fat-soluble substance and accumulates without harm to health. Usually this phenomenon is observed in infants, whose body has not yet adapted to the environment, has not learned to deal with an excess of certain substances.

Cause of vitamin D overdose

There is an acute and chronic form of an overdose of vitamin D. There can be many reasons for the development of this phenomenon. These include:

  • uncontrolled use of the drug without a doctor's recommendation;
  • an incorrect dose was prescribed for the treatment of a small child;
  • prolonged exposure to the sun and the simultaneous use of the drug.

An excess of vitamin D can develop due to parental negligence. Quite often, adults leave the drug in a place accessible to the child, as a result of which he eats a large amount of the substance without parental permission.

General signs of an overdose

Symptoms of drug overabundance are primary and secondary. The primary ones appear almost immediately after excessive intake of the substance, while the secondary ones can appear after a while. The general signs of an overdose are as follows:

  • poor appetite;
  • constant nausea;
  • severe vomiting;
  • unquenchable thirst.

This is how the primary symptoms of poisoning look, after a while secondary ones appear:

  • causeless anxiety and irritability appear;
  • jumps in blood pressure;
  • increased urination;
  • kidney dysfunction appears.

This sign is fraught with serious danger, often has irreversible consequences.

Overdose in adults and children

An overdose of vitamin D3 in adults is much less common than in children. In case of poisoning with this substance, all primary as well as secondary symptoms occur. Depending on the characteristics of the organism, there may be:

  • elevated temperature;
  • sudden weight loss;
  • dysfunction of the nervous system;
  • cardiopalmus;
  • blanching of the skin.

An overdose of vitamin D in adults is characterized by a significant decrease in the immune system, as a result of which a person is constantly sick with infectious and viral diseases.

A child suffering from this kind of intoxication usually has a hard time enduring it. The following symptoms appear:

  • loss of appetite;
  • insomnia appears;
  • the digestive process fails;
  • opens vomiting and diarrhea;
  • the skin turns pale, becomes flabby.

In especially severe cases, respiratory failure develops, convulsions, the heartbeat slows down.

How to treat an overdose

Treatment of an overdose of vitamin D is carried out in a hospital, especially when it comes to young children. First, the source of the substance entering the body is eliminated, then the symptoms of intoxication are removed. For this, adults and children are strictly forbidden to eat:

  • dairy products;
  • chicken eggs;
  • fatty varieties of fish and meat;
  • beef liver.

A complete ban is imposed on exposure to the sun during treatment. The patient is given a lot of fluid, bed rest is prescribed. You can treat an excess of vitamin D with the following drugs:

  • glucocorticosteroids - they are prescribed to relieve inflammation provoked by calcification;
  • ammonium chloride - prevents the formation of calcium stones in the kidneys;
  • vitamins C and B - they help to return the metabolism back to normal.

Why is an overdose dangerous? This phenomenon leads to a number of pathologies:

  • osteoporosis;
  • salt deposition in the tissues of the kidneys, heart and lungs;
  • blockage of blood vessels;
  • arthralgia.

If you take all the necessary measures in time, that is, stop taking the drug, seek help from a doctor, the symptoms of an overdose will pass in a short time.

Vitamin D hypervitaminosis is a disease that occurs in the human body due to an overdose of vitamin D, and is accompanied by hypercalcemia, as well as intoxication of tissues and organs.

Vitamin D belongs to the group of fat-soluble substances and has the ability to accumulate in the body, so self-treatment is not recommended. This disease occurs mainly in children in the first two years of life in the treatment of rickets, but subsequently persists in adults.

It is known that an overdose of D3 during the period of preventive measures is very dangerous, therefore, drugs should be prescribed in accordance with the individual physiological needs of each person. For people with a large body weight and bedridden patients, an excess of vitamin D can cause irreparable harm, since their metabolism is significantly slowed down. The use of vitamin D3 leads to an increase in calcium in the blood, and an excess of this substance leads to hypercalcemia. Penetrating into the walls of blood vessels, as well as the heart, kidneys and lungs, calcium leads to the rapid formation of plaques that clog arteries.

There are two forms of hypervitaminosis D: acute and chronic.

Hypervitaminosis of vitamin D in adults is manifested by a violation of general well-being: a sharp loss of appetite, insomnia, headaches, weakness, pain in the abdomen, nausea, vomiting, significant weight loss, polyuria.

Symptoms of an overdose of vitamin D3

  1. An overdose of vitamin D leads to severe intoxication of the digestive system (nausea, vomiting, loss of appetite, constipation and diarrhea). Symptoms of dehydration are observed (dry mouth, constant thirst, fever);
  2. Signs of an excess of vitamin D3 are manifested by a violation of the functions of the urinary system (significant excretion of urine, the occurrence of chronic pyelonephritis);
  3. An excess of vitamin D leads to a weakening of metabolic functions in the body and a decrease in immunity;
  4. An overdose of this substance disrupts the processes of the cardiovascular system: the skin acquires a bluish tint, the heartbeat changes, cardiopathy and cardioneurosis develop;
  5. Vitamin D hypervitaminosis affects blood pressure and enlargement of the spleen and liver may occur;
  6. During laboratory tests, a large concentration of calcium in the blood is observed, the amount of phosphorus is significantly reduced, protein, leukocytes and traces of blood are found in the urine.

Causes of Vitamin D3 Overdose

An excess of vitamin D most often occurs when the daily intake of this element is increased, which for an adult is up to 1 million IU. In some cases, hypervitaminosis d also appears when taking small doses of this element, which is due to the presence of an increased sensitivity of the body to it.

  • Simultaneous use of D3 and calcium preparations, procedures with ultraviolet baths and taking fish oil, in order to increase immunity;
  • An excess of the element occurs when using an alcohol solution for 3-4 weeks, 10-20 drops each. Due to the use of such a dosage of the substance, acute hypervitaminosis occurs;
  • The use of this element for 5-6 months, 2-5 drops. These dosages are the cause of chronic vitamin D hypervitaminosis;
  • Individual intolerance to a substance is also dangerous to health and may manifest as signs of an excess of vitamin D3.

Treatment of excess D in the body of an adult

Vitamin D hypervitaminosis is treated strictly under the supervision of a specialist, and in severe forms of the disease, treatment is carried out in a hospital. Treatment of this disease is aimed at limiting the intake of this substance in the body and eliminating intoxication. Since hypervitaminosis D can lead to changes in the internal organs of a person, any treatment is accompanied by preliminary examinations and corrections or restorative therapies of damaged tissues and organs.

All foods rich in vitamin D3 and calcium, which have an antioxidant effect, are excluded from the patient's diet:

  • Cottage cheese and cow's milk;
  • Egg;
  • Fish fat.

To ensure the restoration of the body's metabolic processes, auxiliary therapy is prescribed in the form of the use of vitamins of groups B and C. Treatment of hypervitaminosis D that has arisen is aimed at eliminating the signs of hypervitaminosis in the shortest possible time and removing its excess from the body.

In order to prevent an excess of this substance, prevention of its occurrence should be carried out. To do this, you must take drugs prescribed by your doctor that cause an excess of vitamin D3, in strictly prescribed dosages. Unauthorized increase in dosage can cause serious disturbances in the functioning of internal organs and the implementation of vital processes in the body.

If you suspect the first symptoms of vitamin D3 hypervitaminosis, you should immediately contact a specialist, as this condition can be fatal even for an adult who never encounters health problems. It should be remembered that treatment should be prescribed only by a doctor, and carried out in accordance with all requirements, and only then can a positive prognosis of the disease be observed.
