What causes thiamine deficiency?

To function correctly, your body requires the vitamin thiamine. Without enough thiamine, a variety of symptoms can occur, ultimately resulting in death if the deficiency is severe or untreated.

Thiamine deficiency is caused by too little thiamine. This can occur in two ways: either too little thiamine is consumed or too much thiamine is lost. Most diets in the developed world are supplemented with thiamine, making a dietary deficiency of this vitamin very rare. In individuals with incredibly poor or unbalanced diets, such as alcoholics or people in the developing world, it is possible to consume a diet that is deficient in thiamine. In other cases, a genetic condition or kidney condition can result in too much thiamine being lost.

What are the risk factors for thiamine deficiency?

A number of factors increase the risk of developing thiamine deficiency. Most people with risk factors will not get thiamine deficiency because it is very rare, especially in the developed world. Risk factors for thiamine deficiency include:

  • Alcoholism
  • Bariatric surgery
  • Genetic beriberi
  • Kidney disease
  • Living in an impoverished or underdeveloped nation
  • Low socioeconomic status
  • Poor diet
  • Starvation
