Question:
Deficiency of ADH causes following, EXCEPT
Deficiency of ADH causes following, EXCEPT
Show Hint
ADH helps conserve water, so without it urine is dilute and plentiful.
Updated On: Nov 12, 2026
- urine becomes dilute
- person feels thirsty
- Diabetes insipidus occurs
- Concentrated urine is produced
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
ADH (vasopressin) makes the DCT and collecting duct permeable to water, so water is reabsorbed.
Step 2: Effects of deficiency
Without ADH, large amounts of dilute urine are passed. The person feels thirsty from water loss, and the condition is called diabetes insipidus.
Step 3: Find the exception
Production of concentrated urine would need ADH, so it does not occur in deficiency.
Final Answer:
Concentrated urine is not produced when ADH is deficient. \[ \boxed{\text{(D) }\text{Concentrated urine is produced}} \]
