Pellagra is a disease is caused when a person lacks sufficient amount of niacin (vitamin B3) or tryptophan in their diet. Very small amount of niacin or tryptophan in a person’s diet may lead to pellagra. Pellagra may also occur if the body is unable to absorb these nutrients. Thus, it may lead to the development of the disease after gastrointestinal disease or influence of alcohol.

Diarrhea
Scaly skin sores
