What vitamin deficiency causes Beriberi?

Beriberi is a condition that arises from a deficiency in thiamine, which is also known as vitamin B1. This vitamin is essential for converting carbohydrates into energy and plays a crucial role in the metabolism of glucose, which is vital for proper cellular function. When thiamine levels are low, the body's ability to process carbohydrates and utilize them for energy is significantly impaired, leading to the symptoms associated with beriberi, such as muscle weakness, nerve damage, and cardiovascular issues.

The body cannot store thiamine in significant quantities, which makes regular intake through diet crucial for preventing deficiency. Foods rich in thiamine include whole grains, legumes, nuts, and seeds. Understanding the specific role of thiamine in the body helps highlight why its deficiency leads to the distinct clinical manifestations seen in beriberi, reinforcing the importance of adequate nutrition in maintaining overall health.
