Stimulation of the satiety centre or damage of the feeding centre will cause

Options

A. hyperphagia
B. hypophagia or Aphagia
C. overhydration
D. obesity

Answer

**Step-by-Step Solution:**

1. **Understanding the Centers**: The satiety center and feeding center are located in the hypothalamus of the brain. The satiety center is responsible for signaling when to stop eating, while the feeding center signals when to eat.

2. **Effects of Stimulation or Damage**:
- Stimulation of the satiety center leads to a feeling of fullness, reducing the desire to eat.
- Damage to the feeding center can disrupt normal hunger signals, leading to abnormal eating behaviors.

3. **Identifying the Outcomes**:
- If the satiety center is stimulated, a person will feel satisfied and stop eating.
- If the feeding center is damaged, it can lead to conditions such as hyperphagia (excessive eating) or hypophagia (reduced eating).

4. **Analyzing the Options**:
- **Hyperphagia**: This condition involves an increased appetite and is often seen in diabetic patients. It occurs when the feeding center is not functioning properly.
- **Hypophagia**: This condition refers to a reduced appetite or feeding behavior. If the feeding center is damaged, the person may not feel hungry at all, leading to hypophagia or even aphagia (the absence of eating).
- **Over Hydration**: This is related to fluid intake rather than food intake and is not directly linked to the satiety or feeding centers.
- **Obesity**: While obesity can be a consequence of poor regulation of hunger and satiety, it is not a direct result of stimulation of the satiety center or damage to the feeding center.

5. **Conclusion**: Based on the analysis, the correct outcome of stimulating the satiety center or damaging the feeding center is **hypophagia**, where the individual experiences a significant reduction in hunger and food intake.

**Final Answer**: Damage to the feeding center will cause hypophagia.
