Diuresis is prevented by

Options

A. Vasopression
B. Adenaline
C. Epinephrine
D. Somatostain

Answer

### Step-by-Step Solution:

1. **Understand the term "Diuresis":**
- Diuresis refers to the excessive production of urine. This condition leads to increased loss of water from the body through urine.

2. **Identify the effects of diuresis:**
- When there is excessive urine production, the body loses a significant amount of water, which can lead to decreased blood volume and potential dehydration.

3. **Determine the hormones involved in regulating urine production:**
- The key hormone that prevents diuresis is the Antidiuretic Hormone (ADH), also known as Vasopressin.

4. **Explain the function of Vasopressin:**
- Vasopressin acts on the kidneys to promote the reabsorption of water. By increasing water reabsorption, it reduces the volume of urine produced and helps to maintain blood volume and prevent dehydration.

5. **Evaluate the other options:**
- Adrenaline and Epinephrine are stress hormones that do not primarily regulate urine production.
- Somatostatin, also known as Growth Hormone, is involved in growth regulation and does not play a significant role in preventing diuresis.

6. **Conclude with the correct answer:**
- The hormone that prevents diuresis is **Vasopressin** (ADH).

### Final Answer:
Diuresis is prevented by **Vasopressin (ADH)**.
