Question

An adult man feels excessive thirst and excretes large volume of dilute urine. He may be suffering from ______________.

• A. myxoedema
• B. diabetes insipidus
• C. Addison’s disease
• D. acromegaly

Hint:

Diabetes insipidus is related to ADH deficiency, not blood glucose levels.

Answer 1

The Correct Option is B

Step 1: Observing symptoms.
The symptoms include excessive thirst (polydipsia) and passage of large amounts of dilute urine (polyuria).
Step 2: Cause of diabetes insipidus.
Diabetes insipidus is caused by deficiency of ADH (antidiuretic hormone) or reduced kidney response to ADH.
Step 3: Effect on urine formation.
Due to lack of ADH action, water reabsorption is reduced, resulting in dilute urine.
Step 4: Conclusion.
Thus, the condition described is diabetes insipidus.
