Parathormone deficiency in man causes :

Options

A. Hyper calcemia
B. Hypocalcaemia
C. Goitre
D. All

Answer

**Step-by-Step Solution:**

1. **Understand the Role of Parathyroid Hormone (PTH):**
- Parathyroid hormone is secreted by the parathyroid glands, which are located behind the thyroid gland.
- The primary function of PTH is to regulate calcium levels in the blood. It increases blood calcium levels by stimulating bone resorption, which releases calcium into the bloodstream.

2. **Identify the Effects of PTH Deficiency:**
- A deficiency in parathyroid hormone leads to decreased calcium levels in the blood, a condition known as hypocalcemia.
- When PTH is deficient, the body cannot effectively mobilize calcium from the bones, leading to lower calcium levels in the bloodstream.

3. **Recognize Symptoms and Conditions Associated with Hypocalcemia:**
- Hypocalcemia can lead to various symptoms, including muscle cramps, spasms, and potentially more severe complications like seizures or cardiac issues.
- It is important to note that parathyroid hormone deficiency does not cause hyperkalemia (high potassium levels) or gout directly.

4. **Summarize the Consequences of PTH Deficiency:**
- The primary consequence of parathormone deficiency in humans is hypocalcemia.
- Other conditions mentioned in the question, such as hyperkalemia and gout, are not directly related to PTH deficiency.

5. **Conclusion:**
- Therefore, the correct answer to the question is that parathormone deficiency in humans causes hypocalcemia.
