Diuretic substances like tea, coffee, alcohol etc. increases urine output by inhibiting release of hormone

Options

A. Renin
B. Aldosterone
C. ADH
D. Erythropoietin

Answer

To solve the question regarding which hormone is inhibited by diuretic substances like tea, coffee, and alcohol, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Diuretics**:
- Diuretics are substances that promote the production of urine. When someone consumes diuretics, they experience increased urine output, a condition known as diuresis.

2. **Identifying the Hormones**:
- The question lists four hormones: renin, aldosterone, ADH (antidiuretic hormone), and erythropoietin. We need to determine which of these hormones is inhibited by diuretics.

3. **Role of ADH**:
- ADH, or antidiuretic hormone, is responsible for regulating water balance in the body. It promotes the reabsorption of water in the kidneys, reducing urine output. When ADH levels are low, urine output increases.

4. **Effect of Diuretics**:
- Diuretic substances like tea, coffee, and alcohol inhibit the release of ADH. This inhibition leads to decreased water reabsorption in the kidneys, resulting in increased urine output.

5. **Evaluating Other Hormones**:
- **Renin**: This hormone is involved in blood pressure regulation and does not directly affect urine output in the context of diuretics.
- **Aldosterone**: This hormone works with renin to regulate sodium and water balance but is not primarily responsible for the diuretic effect.
- **Erythropoietin**: This hormone stimulates red blood cell production and is not related to urine output.

6. **Conclusion**:
- The hormone that is inhibited by diuretic substances, leading to increased urine output, is ADH (antidiuretic hormone).

### Final Answer:
The correct answer is **ADH (antidiuretic hormone)**.
