Altitude sickness is managed by the body by

Options

A. Decreasing RBC production
B. Increasing fat oxidation
C. Decreasing binding capacity of hemoglobin
D. Decreasing breathing rate

Answer

### Step-by-Step Solution:

1. **Understanding Altitude Sickness**:
- Altitude sickness, also known as mountain sickness, occurs when an individual travels to high altitudes where there is lower air pressure and lower oxygen availability.

2. **Identifying Symptoms**:
- Common symptoms include nausea, lightheadedness, and difficulty sleeping. These symptoms arise as the body struggles to adapt to the reduced oxygen levels.

3. **Body's Response to High Altitude**:
- The body attempts to compensate for the lower oxygen levels through several physiological changes.

4. **Compensatory Mechanisms**:
- **Increase in Red Blood Cell Production**: The body increases the production of red blood cells (RBCs) to enhance oxygen transport.
- **Decrease in Hemoglobin Binding Affinity**: The binding affinity of hemoglobin for oxygen decreases, which allows for easier release of oxygen to tissues.
- **Increase in Breathing Rate**: The respiratory rate increases to take in more oxygen.

5. **Conclusion**:
- Among these compensatory mechanisms, the correct answer to how the body manages altitude sickness is by decreasing the binding affinity of hemoglobin.

### Final Answer:
The body manages altitude sickness by decreasing the binding affinity of hemoglobin.
