Niacin Deficiency [Pellagra]: Symptoms, Causes, and Treatment

Niacin, also known as vitamin B3, is an essential nutrient required for the proper functioning of the body. Pellagra is a condition that occurs due to the deficiency of niacin in the body. Pellagra is characterized by the classic "3 Ds" symptoms, which are dermatitis, diarrhea, and dementia. Pellagra used to be common in the past, but now it is rare in developed countries due to the availability of niacin-rich foods and supplements.

Causes of Niacin Deficiency [Pellagra]

The main cause of pellagra is a diet that lacks niacin. Niacin is found in many foods, such as meat, fish, poultry, legumes, and whole grains. However, people who consume a diet that is low in these foods are at risk of developing pellagra. Other factors that can cause niacin deficiency include alcoholism, anorexia nervosa, Crohn's disease, and certain medications.

1. Dermatitis: Pellagra is characterized by a skin rash that is typically located on areas of the skin that are exposed to sunlight. The rash is usually red, scaly, and itchy.
2. Diarrhea: People with pellagra may experience diarrhea, which can lead to dehydration and electrolyte imbalances.
3. Dementia: In severe cases, pellagra can cause neurological symptoms such as confusion, disorientation, and memory loss.

The treatment for pellagra involves increasing the intake of niacin-rich foods or taking niacin supplements. The recommended daily dose of niacin for adults is 14-16 mg per day for women and 16-18 mg per day for men. In severe cases, niacin supplements may be given intravenously. It is important to diagnose and treat pellagra early to prevent complications.
