Beriberi is a disease caused by a deficiency of thiamine, also known as vitamin B1. It primarily affects the nervous system and can lead to symptoms such as weakness, pain, and swelling. There are two main types: wet beriberi, which affects the cardiovascular system, and dry beriberi, which impacts the nervous system.
This condition is often seen in populations with a diet high in refined carbohydrates and low in thiamine-rich foods, such as whole grains, legumes, and nuts. Treatment typically involves dietary changes and thiamine supplementation to restore health and prevent complications.
