Beriberi is caused by thiamine (vitamin B-1) deficiency. There are two types beriberi; wet and dry beriberi (Wet beriberi: Affects the heart function, Dry beriberi: Affects the nervous system). This might eventually lead two muscle paralyses. The patients are at risk, since the disease affects the major systems in the body. So, proper treatment is necessary. Untreated beriberi can lead to death. Reduce your risk of getting Beriberi by following a healthy diet rich in Vitamin B-1. Meat, dairy products, and whole grains are rich in vitamin B-1. Are you alcoholic? Your chance of developing Beriberi is high, as alcohol addiction leads to poor nutrition. High blood alcohol level affects your capacity to absorb nutrients and vitamins. Dialysis also accelerates the risk of Beriberi. There is a rare type of beriberi known as genetic beriberi, a hereditary case of beriberi.
