Deficiency of Vitamin B1 causes a disease known as beri-beri.
Beriberi is a disease caused by a vitamin B-1 deficiency, also known as thiamine deficiency.
There are two main forms of beriberi:
- Wet beriberi, which mainly affects the cardiovascular system, causing poor circulation and fluid buildup in the tissues.
- Dry beriberi, which primarily affects the nervous system, leading to the degeneration of the nerves. Degeneration typically begins in the legs and arms and may lead to muscle atrophy and loss of reflexes.
