In Hashimoto's disease symptoms develop like :

Options

A. Hyposecretion of thyroxine
B. Hyper secretion of thyroxine
C. Hyposecreation of adrenaline
D. None of the above

Answer

**Step-by-Step Solution:**

1. **Understand Hashimoto's Disease**: Hashimoto's disease is an autoimmune disorder where the immune system attacks the thyroid gland, leading to its dysfunction.

2. **Identify the Symptoms**: The primary symptom of Hashimoto's disease is hypothyroidism, which means the thyroid gland is not producing enough hormones.

3. **Know the Hormones Involved**: The thyroid gland primarily secretes two hormones: Thyroxine (T4) and Triiodothyronine (T3). In Hashimoto's disease, the secretion of these hormones is reduced.

4. **Define Hypothyroidism**: Hypothyroidism is characterized by low levels of thyroid hormones (T3 and T4). The prefix "hypo-" indicates a deficiency.

5. **Evaluate the Options**:
- Hyposecretion of thyroxine: This aligns with the symptoms of Hashimoto's disease.
- Hypersecretion of thyroxine: This is incorrect as Hashimoto's leads to decreased hormone levels.
- Hyposecretion of adrenaline: This is unrelated to Hashimoto's disease.
- None of the above: This is also incorrect since hyposecretion of thyroxine is indeed a symptom.

6. **Conclusion**: The correct answer is "hyposecretion of thyroxine" as it directly relates to the symptoms of Hashimoto's disease.

**Final Answer**: Hyposecretion of thyroxine.
