Pellagra: Symptoms, Causes, and Treatment Options

Pellagra is a nutritional disorder caused by a deficiency of niacin (Vitamin B3) or its precursor tryptophan in the body. It primarily affects populations with limited access to niacin-rich foods, but can also occur due to medical conditions that hinder nutrient absorption. Early diagnosis and treatment are crucial to prevent its severe complications.

Causes and Risk Factors of Pellagra

• Niacin Deficiency: Inadequate intake of niacin due to a poor diet.
• Alcoholism: Excessive alcohol consumption interferes with nutrient absorption.
• Medical Conditions: Chronic diarrhoea, Crohn’s disease, and Hartnup disease can hinder nutrient absorption.
• Medications: Long-term use of certain drugs can affect niacin levels.
• Poverty and Malnutrition: Lack of access to niacin-rich foods is a significant risk factor.
• Vegetarian or Vegan Diets: Without proper supplementation, these diets can lead to niacin deficiency.

Symptoms of Pellagra

• Persistent fatigue and weakness.
• Red or inflamed skin, especially after sun exposure.
• Digestive issues, including diarrhea and abdominal discomfort.
• Irritability, depression, or other mental health changes.
• Swelling of the tongue and mouth sores.
