Alcohol related thiamine deficiency

Thiamine, also known as vitamin B1, is an essential nutrient used by the body to convert food into energy. Thiamine takes the fats, proteins and carbohydrates we consume and uses them to fuel functions of the heart, nerves and brain.

Thiamine deficiency, although rare in most developed countries, is common in people who drink excessive amounts of alcohol. Up to 80% of people with an addiction to alcohol develop thiamine deficiency.

Heavy alcohol use causes inflammation of the stomach lining and digestive tract, which reduces the body’s ability to absorb vitamins. Poor dietary choices and a lack of nutrition also rob the body of essential vitamins.
