Keshan disease

Keshan disease is a rare heart condition mainly found in regions with selenium deficiency, a mineral essential for healthy heart function. It can cause the heart muscle to weaken and enlarge, leading to symptoms like fatigue, swelling, or heart failure. The disease is often linked to poor diet and environmental factors that reduce selenium levels in the body. Ensuring adequate selenium intake through diet or supplements can prevent the disease, especially in vulnerable populations. Keshan disease highlights the importance of proper nutrition for maintaining heart health.
