Which condition can arise from excessive loss of sodium in the body?

Hyponatremia occurs when there is an abnormally low concentration of sodium in the blood. This condition can result from various factors, including excessive loss of sodium due to prolonged sweating, excessive diarrhea, or overuse of diuretics. Sodium is essential for maintaining the balance of fluids in and around cells, regulating blood pressure, and ensuring proper muscle and nerve function. When sodium levels drop significantly, it can lead to symptoms such as headache, confusion, seizures, and even coma, depending on the severity of the deficiency. Understanding this concept emphasizes the critical role that sodium plays in the body and highlights the potential health risks associated with its loss.
