Treatment
The goal of treatment is to replace the thiamine your body is lacking. This is done with thiamine supplements. Thiamine supplements are given through a shot (injection) or taken by mouth.
Other types of vitamins may also be recommended.
Blood tests may be done after you are given thiamine supplements to see how well you are responding to the medicine.
Expectations (prognosis)
Untreated, beriberi is often deadly. With treatment, symptoms usually improve quickly.
Heart damage is usually reversible, and a full recovery is expected. However, if acute heart failure has already occurred, the outlook is poor.
Nervous system damage is also reversible, if caught early. If it is not caught early, some symptoms (such as memory loss) may remain even with treatment.
If a patient with Wernicke's encephalopathy receives thiamine replacement, language problems, unusual eye movements, and walking difficulties may go away. However, Korsakoff syndrome (or Korsakoff psychosis) tends to develop as Wernicke's symptoms go away.
Complications
Calling your health care provider
Beriberi is extremely rare in the United States. However, if you feel your family's diet is inadequate or poorly balanced, and you or your children have any symptoms of beriberi, call your health care provider.
Prevention
Eating a proper diet that is rich in thiamine and other vitamins will prevent beriberi. Nursing mothers should make sure that their diet contains all vitamins and be sure that infant formulas contain thiamine.
People who drink heavily should try to cut down or quit, and take B vitamins to make sure their body is properly absorbing and storing thiamine.
