Diuretics are substances that stimulate the kidneys to remove more fluid from the blood, reducing overall blood volume and relieving pressure on the heart.
Diuretics are pharmacological substances that exert their effects on the kidneys, leading to increased urine production and subsequent removal of excess fluid from the blood. When there is an excess of fluid in the bloodstream, it can result in increased blood volume and elevated blood pressure. Diuretics work by enhancing the excretion of water and electrolytes through the urine, ultimately reducing overall blood volume.
The primary target of diuretics is the renal tubules in the kidneys, where they act to inhibit the reabsorption of sodium and water. By interfering with these processes, diuretics promote the elimination of sodium and water in the urine, causing a net loss of fluid from the body. This reduction in fluid volume within the bloodstream helps alleviate conditions such as hypertension and edema (fluid retention).
