What effect does diuretic have on the body?

Answer 1

They don't have a direct effect, but they cause your body to produce more urine. When that urine is expelled, the total amount of water in your body decreases. Also, "water level" isn't really the best term here. Try "hydration" or "amount of water".

Answer 2

Diuretics reduce in-system water retention, by stimulating urination. Typically, this is done in order to reduce hypertension.

Answer 3

A diuretic increases fluid output from the urinary system.

Answer 4

It makes you urinate more that usuall.
