Quizplus · Accepted Answer

Pellagra is a nutritional deficiency disease caused by inadequate intake of niacin (vitamin B3) and/or tryptophan. The classic signs and symptoms include dermatitis, especially in areas exposed to sunlight, such as the hands, neck, and face. Other symptoms may include diarrhea, dementia, and eventually death if left untreated. Heartburn, weak bones, and night blindness are not classic signs and symptoms of pellagra. Heartburn could be a symptom of acid reflux or gastroesophageal reflux disease (GERD). Weak bones could be a symptom of osteoporosis or another bone disease. Night blindness could be a symptom of vitamin A deficiency.
