Question

Laxative abuse causes which of the following renal stones ?

• A. Uric acid
• B. Ammonium urate
• C. Struvite
• D. Ca oxalate

Answer 1

The Correct Option is B

Laxative abuse is known to cause dehydration and electrolyte imbalances, primarily resulting in hypokalemia (low potassium levels) and acidosis (increased acidity in the blood). These conditions often lead to the precipitation of certain types of renal stones. Specifically, laxative abuse can lead to the formation of ammonium urate stones.

Ammonium urate stones are commonly associated with chronic diarrhea and electrolyte disturbances, particularly hypokalemia. This type of renal stone forms in an environment where there is increased ammonium excretion, often observed under circumstances of severe dehydration or significant acidosis.

Therefore, the correct answer among the options given is:

Ammonium urate
