deficiency of riboflavin (vitamin B2) in the diet, a condition marked by lesions in the corners of the mouth, on the lips, and around the nose and eyes, malaise, weakness, weight loss and, in severe cases, anemia, corneal or other eye changes, and seborrheic dermatitis. It is most common among people in regions such as Asia and the West Indies, where the diet contains large quantities of corn, potatoes, or rice, which lack riboflavin. A well-balanced diet will prevent riboflavin deficiency; it will also correct the disorder, with the help of supplementary doses of riboflavin and other vitamins.
