Beriberi is of two types: wet beriberi and dry beriberi, notes Healthline. While wet beriberi may hinder the normal functioning of the heart, dry beriberi may cause nerve damage, resulting in muscle weakness and eventual muscle paralysis. The symptoms of wet beriberi include rapid heart rate, lower-leg inflammation and shortness of breath while performing physical activities. Dry beriberi causes pain, vomiting, speech difficulty, paralysis and mental confusion.
