What is a result of drinking too much alcohol?

• A. Hyperpigmentation
• B. Hyperhidrosis
• C. Eczema
• D. Anemia

Answer: (A)

Excessive alcohol intake can lead to nutritional deficiencies, and one common deficiency in heavy drinkers is niacin (vitamin B3) deficiency. Niacin is essential for energy production and skin health, and when it’s lacking, pellagra can develop. Pellagra often presents with a photosensitive dermatitis that becomes hyperpigmented in sun-exposed areas. So a skin change like hyperpigmentation can be a consequence of prolonged alcohol use due to niacin deficiency. While anemia or eczema can occur in alcohol users for other reasons, they don’t explain this specific pigmented skin change as directly as pellagra-associated dermatitis does; hyperhidrosis isn’t a typical direct result of drinking too much.
