vitamin deficiency, in particular, insufficient intake of B vitamins into the body;

Vitamin D deprivation and cognitive disorders: observational approach in older adults

As a result, the optimal balance of nutrients in the body is disturbed, and primary hypovitaminosis develops.

On the part of the metabolism: in rare cases - lactic acidosis (requires discontinuation of treatment), with long-term treatment - hypovitaminosis B12 (impaired absorption).

From the side of metabolism: rarely – lactate-acidosis (requires discontinuation of treatment); with prolonged treatment – hypovitaminosis B12 (impaired absorption).

Endogenous: somatic diseases that invariably cause a general weakening of the body, hypovitaminosis, impaired metabolic processes.

But this does not mean that the inhabitants of the northern regions very often suffer hypovitaminosis D or rickets.

With persistent pancreatic diarrhea, the electrolyte balance of the blood is disturbed and hypovitaminosis develops.

– A physiological K hypovitaminosis in newborns, it is due to an intake or absorption failure;

From the side of metabolism: rarely – lactate-acidosis (requires discontinuation of treatment); with prolonged treatment – hypovitaminosis B12 (impaired absorption).

Most elderly people are deficient in vitamin D but not all will develop Alzheimer’s disease.

On the part of the metabolism: in rare cases - lactic acidosis (requires discontinuation of treatment), with long-term treatment - hypovitaminosis B12 (impaired absorption).

This is explained by the fact that such actions can provoke the development of hypovitaminosis and protein starvation.

Avitaminosis, multivitaminosis, hypovitaminosis - all these deviations are the result of a violation of the absorption and distribution of vitamins.

In adverse conditions (hypovitaminosis, depletion, the presence of foreign bodies, and so on) ripening of granulation tissue are extended.
