What term refers to substances that promote increased excretion of urine?

The correct term for substances that promote increased excretion of urine is "diuretic." Diuretics are often used in medical settings to help reduce fluid retention or manage conditions such as hypertension. They function by inhibiting the reabsorption of sodium in the kidneys, which subsequently leads to increased water loss in urine.

The other terms provided refer to different concepts entirely. Bulimia is an eating disorder characterized by episodes of binge eating followed by compensatory behaviors to prevent weight gain, such as vomiting or excessive exercise. Episodic typically describes events occurring in a series or specific periods without a direct connection to urine excretion. Anorexia Nervosa is another eating disorder focused on excessive weight loss and an intense fear of gaining weight, which does not involve the promotion of urine excretion. Thus, diuretic is the precise term that describes substances that influence urine production.
