Definition & Meaning of "beriberi"

What is "beriberi"?

Beriberi is a condition caused by a lack of vitamin B1, also known as thiamine, in the diet. It mainly affects the nervous system and cardiovascular system, leading to symptoms such as fatigue, weakness, tingling or numbness in the hands and feet, difficulty walking, and swelling in the lower legs. In serious cases, beriberi can cause heart failure and neurological problems, including paralysis. Beriberi is most commonly seen in regions where diets are heavily based on polished rice or other refined grains, which lack sufficient thiamine. Treatment typically involves thiamine supplementation and dietary changes to address the underlying lack of vitamin B1. With quick treatment, the symptoms of beriberi can often be reversed, although serious cases may require more thorough medical treatments.
