ICD-11 code : 5B5B;
Preferred Label : Vitamin B2 deficiency;
ICD-11 definition : The signs of riboflavin deficiency are sore throat, hyperaemia, oedema of the pharyngeal
and oral mucous membranes, cheilosis, angular stomatitis, glossitis, seborrheic dermatitis,
and normochromic normocytic anaemia associated with pure red cell cytoplasia of the
bone marrow. The major cause of hyporiboflavinosis is inadequate dietary intake as
a result of limited food supply, which is sometimes exacerbated by poor food storage
or processing. Children in developing countries will commonly demonstrate clinical
signs of riboflavin deficiency during periods of the year when gastrointestinal infections
are prevalent. Decreased assimilation of riboflavin also results from abnormal digestion,
such as that which occurs with lactose intolerance.;
