When your body holds onto too much fluid, it can raise your blood pressure and make you feel swollen or tired. That’s where thiazide diuretics, a class of medications that help your kidneys remove extra salt and water. Also known as water pills, they’re one of the most common starting points for treating high blood pressure in the U.S. Unlike stronger diuretics, thiazides work slowly and steadily—pulling out just enough fluid to ease pressure on your blood vessels without draining you dry.

That’s why many doctors pair them with potassium supplements or combine them with other blood pressure meds like ACE inhibitors. And while hydrochlorothiazide, the most common thiazide diuretic.
