Definition:
  1. As a noun, a diuretic is a substance, often a drug, that encourages the body to rid itself of fluids through urination.
  2. "Diuretic" can also be used as an adjective describing anything that encourages urination.

Some use diuretics as weight-loss aids, but the lost weight from using diuretics is only water weight and is quickly regained. Not only are diuretics ineffective for sustained weight loss, but they also are potentially dangerous because of electrolyte disturbances and lowered blood pressure.

Pronunciation: DIE-uh-RET'-iks
Also Known As: water pills
Common Misspellings: diaretics
Examples: Though her mom's diuretic was prescribed to relieve swelling in feet and hands, Iris popped them regularly in an ineffective attempt to lose weight.
