Diabetes insipidus disease is caused due to the deficiency of hormone produced by

Options

A. Pituitary
B. Adrenal
C. Pancreas
D. Thyroid

Answer

**Step-by-Step Solution:**

1. **Understanding Diabetes Insipidus**:
- Diabetes insipidus is a condition characterized by excessive thirst and the excretion of large amounts of severely diluted urine. This occurs despite normal or increased fluid intake.

2. **Identifying the Hormone Involved**:
- The key hormone involved in regulating water balance in the body is vasopressin, also known as antidiuretic hormone (ADH).

3. **Source of Vasopressin**:
- Vasopressin is produced in the hypothalamus and stored and released from the posterior pituitary gland.

4. **Cause of Diabetes Insipidus**:
- Diabetes insipidus is primarily caused by a deficiency of vasopressin. This deficiency can result from damage to the pituitary gland or hypothalamus, leading to inadequate secretion of this hormone.

5. **Evaluating the Options**:
- The options provided are:
- A) Pituitary
- B) Adrenal
- C) Pancreas
- D) Thyroid
- Since vasopressin is produced in the hypothalamus and released from the pituitary gland, the correct answer is the pituitary gland.

6. **Conclusion**:
- Therefore, diabetes insipidus is caused by the deficiency of the hormone vasopressin, which is produced by the pituitary gland. Thus, the correct answer is **A) Pituitary**.
