Osteroporosis,osteomalacia,kidney stone formation are due to

Options

A. Hyper parathyroidism
B. Hyperthyroidism
C. Hyper insulinimia
D. Hypothyroidism

Answer

To solve the question regarding the causes of osteoporosis, osteomalacia, and kidney stone formation, we will analyze the provided options step by step.

### Step 1: Understand the Conditions
- **Osteoporosis**: A condition characterized by weakened bones, making them fragile and more likely to fracture.
- **Osteomalacia**: A softening of the bones due to a deficiency of vitamin D or calcium, leading to weak bones.
- **Kidney Stones**: Hard deposits made of minerals and salts that form inside the kidneys, often related to high calcium levels in the blood.

### Step 2: Analyze the Options
1. **Hyperparathyroidism**: This condition involves an overproduction of parathyroid hormone (PTH), which increases calcium levels in the blood by promoting bone resorption (dissolving bone tissue) and increasing calcium absorption in the kidneys. This can lead to osteoporosis, osteomalacia, and kidney stone formation due to excess calcium.

2. **Hyperthyroidism**: This condition involves an overproduction of thyroid hormones, which primarily affects metabolism and does not have a direct impact on calcium levels or bone density.

3. **Hyperinsulinemia**: This condition involves excess insulin in the blood, primarily affecting glucose metabolism and not directly related to calcium metabolism or bone health.

4. **Hypothyroidism**: This condition involves a deficiency of thyroid hormones, which also does not directly affect calcium metabolism or bone density.

### Step 3: Conclusion
Based on the analysis, **hyperparathyroidism** is the condition that leads to osteoporosis, osteomalacia, and kidney stone formation due to its impact on calcium metabolism and bone health.

### Final Answer
The correct answer is **hyperparathyroidism**.
