What is thiamine deficiency?

Thiamine deficiency (beriberi) results when your body does not have enough of the vitamin thiamine. Your body requires thiamine to help it break down different types of sugar. Without enough thiamine, you may experience a variety of symptoms that can be serious. Because many foods are supplemented with thiamine, thiamine deficiency is rare in the United States. However, thiamine deficiency is possible in some people with rare genetic conditions, in people who eat very unbalanced diets, in alcoholics, and in some people with kidney disease.

Depending on the level of thiamine deficiency, symptoms can vary greatly. There are two primary types of thiamine deficiency: wet beriberi and dry beriberi. Wet beriberi includes symptoms somewhat like those of congestive heart failure (heart failure is a deterioration of the heart’s ability to pump blood), including difficulty breathing and lower leg swelling. Dry beriberi mainly affects nerves and has symptoms that include weakness (loss of strength) and paralysis.

Thiamine deficiency is usually treated with thiamine supplements and by adjustments to your diet or lifestyle that will help prevent a future occurrence. If the condition is discovered early and treated promptly, a full recovery is likely. In cases when thiamine deficiency is untreated or treated late, serious complications are probable.

Seek prompt medical care if you suspect you might have thiamine deficiency or if you have symptoms of thiamine deficiency, including numbness or tingling (possibly accompanied by weakness, clumsiness, confusion, or difficulty thinking) or symptoms of congestive heart failure, such as swelling in your legs and shortness of breath.
