 Pellagra is caused by a lack of Vitamin B3 (niacin) in the diet or poor absorption of the vitamin. It is common throughout the world but infrequent in the U.S. It primarily strikes those lacking protein in their diets or who have a high corn diet or are unable to assimilate the vitamin. Symptoms often begin with weakness, listlessness, insomnia, and weight loss. Exposed skin becomes red and scaly. Loss of appetite, indigestion, and diarrhea occur. As the disease progresses the nervous system is impacted, manifesting symptoms such as headaches, dizziness, aches, muscle tremors and mental disturbances.
