What is the purpose of water pills? do they aid in weight loss?

Diuretics: Water pills (diuretics) cause the kidneys to produce more urine. The urine comes from total body water which leads to water loss and ultimate weight loss. They should not be used for the purpose of weight loss, however, as diuretics can harm the kidneys and disturb electrolyte balance.

Diuretics: Diuretics are used to assist people in heart failure or with severe hypertension to pee off excess fluids that their heart is having a hard time clearing. In no way do these medications cause one to increase their metabolism or to lose weight. It is a dangerous myth and a lie if anyone tells you otherwise.
