| Causes Deficiency occurs due to
a deficient diet or due to administration of riboflavin antagonists such as galactoflavin.
Signs and symptoms
Sore throat and angular stomatitis generally appear first. Later, glossitis, cheilosis,
dermatitis of the face, dermatitis over the trunk and extremities, occur followed by
anemia and neuropathy. In some subjects, corneal vascularization and cataract formation
are prominent. Anaemia in patients with riboflavin deficiency may be related, at least in
part, to disturbances in folic acid metabolism.
Prevention and treatment
Administration of the vitamin in the case of deficiency reverses the signs and
symptoms.
