Definition & Meaning of "pellagra"

What is "pellagra"?

Pellagra is a condition caused by a lack of vitamin B3, also know as niacin, in the diet. It typically occurs in people whose diet lacks variety and includes mainly corn-based products, which are low in niacin. Pellagra can cause a range of symptoms, including skin rashes, diarrhea, dementia, and depression. If left untreated, it can lead to serious complications affecting the skin, digestive system, and nervous system. Treatment involves increasing niacin intake through dietary changes or supplements. With proper nutrition, pellagra can be prevented and treated effectively.
