Pellagra is a systemic disease caused by a severe deficiency of vitamin B3 (Niacin). A mild deficiency might go unnoticed, but a chronically low or Niacin-free diet can result in symptoms. The primary symptoms include diarrhea, skin inflammation, inflammation of the mucous linings (inside the mouth), mental confusion, and weakness. If untreated, it can lead to death.
Your doctor may ask these questions to check for this disease:
Pellagra is treated with dietary changes and supplementation of niacin or nicotinamide (another form of vitamin B-3). These vitamins can be given orally or injected intravenously. With early treatment, many people fully recover and begin to feel better within a few days of starting treatment.

Male, 20s
My experience was great. I was worried, but the symptom checker helped me narrow down what it might be. I feel a little relieved compared to when I first started, and it gives me a starting point for what my symptoms could mean.

Male, 50s
The questions asked and possible causes seemed spot on, putting me at ease for a next-step solution.

Female, 40s
I was actually very impressed with the results it provided because, although I didn’t mention it during the questionnaire because I thought it was unrelated, it suggested I may have something I’ve actually been diagnosed with in the past.
