Diseases caused by excess vitamins

Using too much vitamin C can cause hemolysis, increasing free radicals. Excess vitamin C can also lead to insomnia, kidney stones, and insulin secretion.

Vitamins are essential substances for human life but the body cannot synthesize itself but must be brought from outside. Vitamin deficiency (due to lack of supply or reduced absorption) is often expressed in different forms of disease, often with vitamin treatment. However, supplementing with too many vitamins or taking it without a vitamin deficiency may cause this substance to be exacerbated.

Vitamin A: The role of creating retinal pigment, differentiation of epithelial cells, participating in bone regeneration, is indicated for the treatment of eye, bone, skin diseases .

High doses may cause vitamin A poisoning; In children can increase intracranial pressure, bone pain, dermatitis, optic nerve atrophy and blindness. For adults, excess vitamin A can cause headaches, menstrual disorders, liver failure, increased blood calcium, mental disorders, teratogenicity in pregnant women.

Vitamin B6: Coenzyme in amino acid metabolism, involved in hematopoiesis, epithelial regeneration; while participating in the conversion of tryptophan into serotonin, an important substance of the nervous system.

The use of high doses or prolonged use of many months may cause excess vitamin B6, manifested by polyneuropathy, memory loss, elevated liver enzymes .

Vitamin B12: As coenzyme involved in synthesis of nucleic acid and myelin, it has a role in the structure and activity of the nervous system, hematopoiesis, regeneration of liver parenchyma.

Excess vitamin B12 (usually due to high dose injection), can cause activation of the coagulation system to increase coagulation, causing embolism.

Vitamin C: Has a role to join the structure of the association, synthesize catecholamine, neutralize free radicals, increase the body's resistance.

High doses may cause hemolysis, especially in people who lack glucose 6 phosphate dehydrogenase, who have increased serum iron. This condition can also increase free radicals, insomnia, agitation, kidney stones, reduce insulin secretion, reduce blood clotting time .

Vitamin D: Has a role in bone regeneration, increases calcium absorption from the intestine and regulates blood calcium levels.

Excess vitamin D will increase blood calcium; In children under 1 year old can cause irritation, seizures, early bone cartilage. For adults, high doses may cause loss of appetite, vomiting, diarrhea, mental disorders, and even death.

Vitamin E: Participation prevents lipid oxidation in cell membranes, antioxidants.

Excess vitamin E can cause digestive disorders, headaches, visual disturbances, inhibiting sexual function, causing kidney damage.

Many other vitamins when excess can also cause illness, danger to health. Therefore, it should be conceived that vitamins as well as other drugs, if not indicated, are not used. When using vitamins, avoid excessive state.

Without vitamin deficiency, there is no need for supplementation with drugs, but vitamins can be used as food. If taking the drug, choose an oral route; unless the gastrointestinal tract is unabsorbed by vitamins or has to be nourished. The dose of vitamins must depend on the condition of each person (children, adults, pregnant women, pathological status .). Do not use a complex of oil-soluble vitamins, because it is easy to cause vitamin accumulation.
