Thiamine deficiency is a medical condition of low levels of thiamine (vitamin B1).[1] A severe and chronic form is known as beriberi.[1][7] The name beriberi was possibly borrowed in the 18th century from the Sinhalese phrase බැරි බැරි (bæri bæri, “I cannot, I cannot”), owing to the weakness caused by the condition. The two main types in adults are wet beriberi and dry beriberi.[1] Wet beriberi affects the cardiovascular system, resulting in a fast heart rate, shortness of breath, and leg swelling.[1] Dry beriberi affects the nervous system, resulting in numbness of the hands and feet, confusion, trouble moving the legs, and pain.[1] A form with loss of appetite and constipation may also occur.[3] Another type, acute beriberi, found mostly in babies, presents with loss of appetite, vomiting, lactic acidosis, changes in heart rate, and enlargement of the heart.[8]
Risk factors include a diet of mostly white rice, alcoholism, dialysis, chronic diarrhea, and taking high doses of diuretics.[1][6] In rare cases, it may be due to a genetic condition that results in difficulties absorbing thiamine found in food.[1] Wernicke encephalopathy and Korsakoff syndrome are forms of dry beriberi.[6] Diagnosis is based on symptoms, low levels of thiamine in the urine, high blood lactate, and improvement with thiamine supplementation.[9]
Treatment is by thiamine supplementation, either by mouth or by injection.[1] With treatment, symptoms generally resolve in a few weeks.[9] The disease may be prevented at the population level through the fortification of food.[1]
Thiamine deficiency is rare in the United States.[10] It remains relatively common in sub-Saharan Africa.[2] Outbreaks have been seen in refugee camps.[6] Thiamine deficiency has been described for thousands of years in Asia, and became more common in the late 1800s with the increased processing of rice.[11]
