What is the primary function of diuretics?

The primary function of diuretics is to elevate urine excretion. Diuretics work by promoting the kidneys to remove excess sodium and water from the body, which results in increased urine production. This mechanism is particularly useful in managing conditions such as hypertension (high blood pressure) and edema (swelling due to fluid retention). By reducing fluid volume in the bloodstream, diuretics can help decrease blood pressure and the burden on the heart, making them an important part of treatment for certain medical conditions.
