Diuretics can help to reduce swollen feet and ankles, and prevent fluid build-up on the lungs, allowing you to be more active and breathe more easily.
Diuretics cause your body to get rid of excess fluid by making you urinate more often. Your heart won't have to work as hard if there's less fluid to pump around the body. If you have gout
, diuretics can make it worse. They can also lower your blood pressure
, which may make you feel dizzy.
