What is the main effect of diuretics on the body?

  1. Decrease appetite

  2. Increase muscle mass

  3. Increase urine output

  4. Reduce blood sugar levels

The correct answer is: Increase urine output

Diuretics primarily function to increase urine output in the body, which is their main therapeutic effect. These medications work by promoting the expulsion of sodium and water from the kidneys, leading to increased urine production. This mechanism is often utilized to manage various medical conditions, such as hypertension and edema, as it helps to decrease fluid overload and lower blood pressure. The other options do not accurately describe the primary effects of diuretics. While some medications may have secondary effects, they do not represent the fundamental action of diuretics, which is centered around the regulation of fluid balance and kidney function.
