What deficiency results in Beriberi?

Beriberi is caused by a deficiency in Vitamin B1, also known as thiamine. This vitamin plays a crucial role in carbohydrate metabolism and is essential for the proper functioning of the nervous system, muscles, and heart. When there is inadequate thiamine in the diet, it leads to disruptions in energy production at the cellular level, particularly affecting the cardiovascular and nervous systems. This can manifest in symptoms such as weakness, fatigue, and in severe cases, neurological issues, and heart problems.

The condition can present itself in two main forms: wet beriberi, which primarily affects the cardiovascular system, causing edema and heart complications, and dry beriberi, which predominantly impacts the nervous system, leading to symptoms like muscle weakness and neuropathy. This relationship emphasizes the importance of Vitamin B1 in maintaining health and highlights the dangers associated with its deficiency.
