Hashimoto disease is caused, when:

Options

A. Adrenal gland is destroyed by autoimmunity
B. Thyroid gland is destroyed by autoimmunity
C. Kidney is destroyed
D. Pancreas is destroyed

Answer

**Step-by-Step Solution:**

1. **Understanding Hashimoto Disease**: Hashimoto disease is an autoimmune disorder where the immune system mistakenly attacks the body's own tissues. In this case, it specifically targets the thyroid gland.

2. **Identifying the Affected Gland**: The thyroid gland is a butterfly-shaped gland located in the neck. It plays a crucial role in regulating metabolism through the production of hormones such as T3 (triiodothyronine) and T4 (thyroxine).

3. **Mechanism of the Disease**: In Hashimoto disease, the immune system produces antibodies that attack and destroy the thyroid gland. This leads to a decrease in the production of thyroid hormones, which can result in symptoms of hypothyroidism.

4. **Evaluating the Options**: The question provides four options regarding which gland is destroyed by autoimmunity in Hashimoto disease:
- Adrenal gland
- Thyroid gland
- Kidney
- Pancreas

5. **Selecting the Correct Answer**: Since Hashimoto disease specifically involves the destruction of the thyroid gland by the immune system, the correct answer is the second option: "thyroid gland."

**Final Answer**: Hashimoto disease is caused when the thyroid gland is destroyed by autoimmunity.
