Osteoporosis disease is caused by hypersecretion of

Options

A. Thyroid
B. Adrenals
C. Parathyroid
D. Pituitary

Answer

**Step-by-Step Solution:**

1. **Identify the Disease**: The question asks about osteoporosis, which is a condition characterized by weakened bones and increased risk of fractures.

2. **Understand Hypersecretion**: Hypersecretion refers to the excessive production of a hormone. In this case, we need to identify which hormone's hypersecretion leads to osteoporosis.

3. **Locate the Relevant Gland**: The parathyroid gland is crucial in this context. It is located near the thyroid gland and is responsible for regulating calcium levels in the body.

4. **Identify the Hormone**: The parathyroid gland secretes parathormone (also known as parathyroid hormone or PTH). This hormone plays a significant role in calcium homeostasis.

5. **Understand the Function of Parathormone**: Parathormone increases calcium levels in the blood by:
- Stimulating bone resorption (release of calcium from bones into the bloodstream).
- Increasing calcium reabsorption in the intestines.
- Decreasing calcium excretion in the urine.

6. **Link to Osteoporosis**: When there is hypersecretion of parathormone, it leads to excessive bone resorption. This results in decreased bone density, which is the hallmark of osteoporosis.

7. **Conclusion**: Therefore, osteoporosis is caused by the hypersecretion of parathormone.

**Final Answer**: Osteoporosis disease is caused by hypersecretion of parathormone.
