Vitamin deficiency – how it manifests itself

Vitamin deficiency, or avitaminosis, is a disease in which there is a complete lack or severe deficiency of one of the vitamins.


Vitamins are components necessary for the functioning of the entire body, therefore vitamin deficiency can be very dangerous and is associated with the occurrence of characteristic symptoms.

Vitamin deficiency - types


Avitaminosis can occur as a primary or secondary disease. Primary avitaminosis is one that occurs when the body’s supply of vitamins is limited. Secondary vitamin deficiency is when the supply of vitamins is correct, but as a result of various diseases or an incorrect lifestyle (drinking alcohol, smoking), certain vitamins are lost or improperly absorbed, or assimilated.

Vitamin deficiency can be very difficult to diagnose. Very often, in the presence of various clinical symptoms, the search for specific diseases begins, but it is forgotten that they may be caused by a deficiency or lack of a vitamin.

If avitaminosis is found in the body, oral supplementation or administration of the vitamin via the muscle or intravenous route is used.
