Diuretics help the body get rid of excess fluid, mainly water and sodium. Most stimulate the kidneys to excrete more sodium into the urine. When diuretics flush away sodium, the body also flushes away water.

Doctors prescribe diuretics when the body is retaining too much fluid. This problem is more common in older adults. The following conditions may require the regulation of fluid in the body or result in fluid retention:
