Sodium regulation refers to the body's ability to maintain the proper balance of sodium, an essential mineral, in the bloodstream. Sodium plays a crucial role in various bodily functions, including fluid balance, nerve transmission, and muscle contraction. The kidneys are primarily responsible for regulating sodium levels by filtering excess sodium from the blood and excreting it through urine. When sodium intake is too high, the body may retain excess fluid, leading to increased blood pressure and potential health issues. Conversely, low sodium levels can result in symptoms like headaches, confusion, and muscle cramps. Maintaining a balanced diet with appropriate sodium levels is important for overall health.
