In alcoholics, urine is

Options

A. Hyperosmotic
B. Isoosmotic
C. Hypoosmotic
D. Alkaline

Answer

To answer the question "In alcoholics, urine is," we need to analyze the effects of alcohol on the body, particularly focusing on the hormone regulation and urine concentration.

### Step-by-Step Solution:

1. **Understanding Alcohol's Effect on Hormones**:
- Alcohol consumption inhibits the release of vasopressin (also known as antidiuretic hormone or ADH). This hormone is crucial for regulating water balance in the body.

**Hint**: Consider how hormones influence kidney function and water retention.

2. **Role of Vasopressin (ADH)**:
- Vasopressin normally promotes water reabsorption in the kidneys. When its release is inhibited, the kidneys do not reabsorb as much water.

**Hint**: Think about what happens when the body cannot retain water effectively.

3. **Impact on Urine Production**:
- With less vasopressin, the kidneys excrete more water, leading to increased urine production. This results in urine that is more diluted.

**Hint**: Reflect on how urine concentration changes with increased water output.

4. **Determining Urine Osmolarity**:
- Since the urine produced is more diluted due to the excess water being excreted, it is classified as hypoosmotic (lower osmolarity compared to blood plasma).

**Hint**: Recall the definitions of hyperosmotic, isosmotic, and hypoosmotic solutions.

5. **Final Answer**:
- Therefore, in alcoholics, the urine is **hypoosmotic**.

### Summary of the Answer:
In alcoholics, urine is hypoosmotic due to the inhibition of vasopressin (ADH) by alcohol, leading to increased water excretion by the kidneys.
