Diuretics, also known as water pills, are medications that stimulate the kidneys to produce more urine, flushing excess fluids from the body. They are frequently prescribed to treat a number of conditions, including high blood pressure, heart failure and kidney disease.

Reducing salt and water levels in the body lowers blood pressure throughout the body, decreasing stress on the heart, kidneys and other organs. Large-scale studies have found that diuretics reduce the risk of heart attack and stroke.

People with diabetes who take diuretics should carefully monitor their glucose (blood sugar) levels because these medications may increase the risk of hyperglycemia (high blood glucose). In addition, use of diuretics by nondiabetics may increase their risk of developing diabetes. A physician will decide if diuretics should be incorporated into an individual’s treatment plan.
