"In the spoon - medicine, in the cup - poison," - says an old Russian proverb. Its meaning is simple: even the most useful substances can harm the fragile balance of the body if they are used excessively. Consider how dangerous an overdose of vitamin D.
Vitamin D - general information
Vitamin D , or calciferol, is a fat-soluble vitamin, which is also a hormone. It was isolated from fish oil in 1936. It is proved that the body is able to produce it independently, if it receives enough sunlight.
Today I distinguish two forms of this vitamin:
- vitamin D2 - a synthetic vitamin, formed as a result of the influence of ultraviolet rays on some fungi; it is added to various bioadditives;
- vitamin D3 - natural vitamin D, found in food of animal origin, is most well absorbed by the human body.
Vitamin D affects the kidneys, intestines and all the muscles of a person, is involved in the process of calcium transport and its reabsorption. There are also additional forms such as vitamin D4, D5, D6. An overdose of vitamin D is also dangerous, as is its lack.
The norm of vitamin D for humans
Scientists have determined that the average daily norm of vitamin D is 300-600ME or 5 mcg, and the maximum possible harmless amount per day - up to 15 mcg. This dosage is suitable for adults without variations in weight parameters.
The dose of vitamin D for children under 12 years is 400-500 IU per day. Do not give your child more vitamin D!
Symptoms of an overdose of vitamin D
The symptoms of an overdose of vitamin D are pretty obvious, and you'll easily find them if they are available. Among them you can list the following:
- Nausea, weight loss, total or partial loss of appetite.
- Polydipsia is a phenomenon in which an abnormally strong thirst arises that can not be quenched.
- Polyuria - markedly increased urine formation.
- Hypertension is a steady increase in blood pressure.
- Constipation and other problems with the intestines.
- Muscle rigidity.
- Renal insufficiency, painful sensations in the kidney area.
- Brain pressure.
- Acidosis, that is, a strong shift of the acid-base balance to acidity.
- Fragility of the skeleton, fragility of bones due to a violation of calcium metabolism and calcium deposition on other organs.
- For children, such changes as poor development, low body weight, irritability, weak growth are actual. Especially dangerous is staying in the sun, taking fish oil or vitamin D in this state.
It is known that a prolonged overdose of vitamin D leads to sad consequences. It is very important to notice and prevent the further development of the disease in time.
Overdose of vitamin D - treatment
The first thing to do when an overdose of vitamin D - is to cancel the drug. If he enters the complex (multivitamins or fish oil), then cancel
In addition, long exposure to sun or tanning in a solarium is not recommended. In the hot season, try to wear light, but closed clothing for at least the first few days.
Another important measure is a plentiful drink. It is worth choosing not mineral water or juices, but simple clean drinking water without gas. You need to consume it at least 2-3 liters per day. Watch this, taking 30 minutes before eating and an hour later after 1-2 glasses. Be sure to monitor the drinking regime at least 1-2 weeks after the discovery of an overdose .
