Disease caused by hypoactivity of anterior pituitary gland is

Options

A. Dwarfism
B. Gigantism
C. Acromegaly
D. Cushing disease

Answer

**Step-by-Step Solution:**

1. **Identify the Gland Involved**: The anterior pituitary gland is responsible for producing several hormones, including the growth hormone (GH).

2. **Understand Hypoactivity**: Hypoactivity of the anterior pituitary gland means that it is not producing enough hormones. In this case, we are particularly interested in the growth hormone.

3. **Link Hypoactivity to Diseases**: When the anterior pituitary gland does not secrete enough growth hormone, it can lead to specific conditions. The most notable condition associated with low levels of growth hormone is dwarfism.

4. **Differentiate Between Conditions**:
- **Dwarfism**: Caused by low secretion of growth hormone before puberty, leading to stunted growth.
- **Gigantism**: Caused by excess growth hormone secretion before puberty, resulting in excessive growth.
- **Acromegaly**: Caused by excess growth hormone after puberty, leading to enlargement of body parts.
- **Cushing's Disease**: Not related to growth hormone; it involves excess cortisol due to adrenal gland issues.

5. **Conclusion**: Based on the information, the disease caused by hypoactivity of the anterior pituitary gland is dwarfism.

**Final Answer**: The disease caused by hypoactivity of the anterior pituitary gland is **dwarfism**.
