Avitaminosis is any disease caused by chronic or long-term vitamin deficiency or caused by a defect in metabolic conversion, such as tryptophan to niacin. They are designated by the same letter as the vitamin.^[1]^[2]

Conversely hypervitaminosis is the syndrome of symptoms caused by over-retention of fat-soluble vitamins in the body.

Types

Avitaminoses (and their lacking factors) include:

Vitamin A deficiency (retinal and carotenoid precursors) causes xerophthalmia or night blindness.
Thiamine deficiency (vitamin B1) causes beriberi.
Niacin deficiency (vitamin B3) causes pellagra.
Vitamin B12 deficiency (cyanocobalamin) leads to megaloblastic anemia and subacute combined degeneration of spinal cord.
Vitamin C deficiency (ascorbic acid) leads to scurvy.
Vitamin D deficiency (cholecalciferol, ergocalciferol or lack of sunlight) causes rickets.
Vitamin K deficiency (phylloquinone or menaquinone) causes impaired coagulation.
