How much weight can you lose with diuretics?
At least two pounds will be lost as a result of the potassium-sparing diuretics detailed in later sections, and if you lower your body weight excessively, you should consume water to ensure you are 2-3 pounds HEAVIER than your required weight before sleep.
Can diuretics cause weight loss?
The truth is, diuretics only cause you to lose water weight, and that weight loss won't last. More importantly, using diuretics in this way can lead to dehydration as well as side effects. Never take prescription diuretics without your doctor's guidance.
