Diuretics, sometimes called water pills, help rid your body of salt (sodium) and water. They work by making your kidneys put more sodium into your urine. The sodium, in turn, takes water with it from your blood. That decreases the amount of fluid flowing through your blood vessels, which reduces pressure on the walls of your arteries.

For high blood pressure, diuretics, commonly known as "water pills," help your body get rid of unneeded water and salt through the urine. Getting rid of excess salt and fluid helps lower blood pressure and can make it easier for your heart to pump. Diuretics may be used to treat a number of heart-related conditions, including high blood pressure, heart failure, kidney and liver problems, and glaucoma.

Of those conditions in which excess fluids build up in your body, congestive heart failure (CHF) is the one most commonly treated with diuretics. If you have CHF, your heart is not circulating blood effectively and this results in a buildup of fluids throughout your body, also known as edema.

Other, more rare conditions can cause an excess of fluids and be treated with diuretics. These include edema caused by reasons other than CHF, such as diabetes, and certain types of kidney and liver disease.

Water pills used for urinary tract disorders, including infections of the kidney, bladder, and urethra; swelling (inflammation) of the urinary tract; increased urination; painful urination; bed-wetting; reduce bacteria in urine; and urine that contains excess uric acid or other acids. Also used for constipation and a lung condition called bronchitis.
