ICD-11 code : 5B5D;
Preferred Label : Vitamin B6 deficiency;
ICD-11 definition : A deficiency of vitamin B6 alone is uncommon because it usually occurs in association
with a deficit in other B-complex vitamins. Hypovitaminosis B6 may often occur with
riboflavin (vitamin B2) deficiency. The classical clinical symptoms of vitamin B6
deficiency are a seborrheic dermatitis, microcytic anaemia, epileptiform convulsions,
and depression and confusion. Infants are especially susceptible to insufficient intakes,
which can lead to epileptiform convulsions. Moreover, there is usually a decrease
in circulating lymphocytes and sometimes a normocytic, microcytic, or sideroblastic
anaemia as well. As is the case with other micronutrient deficiencies, vitamin B6
deficiency results in an impairment of the immune system. Several medical conditions
can also affect vitamin B6 metabolism and thus lead to deficiency symptoms.;
