Which conditions are commonly treated to reduce nocturia (as examples mentioned)?

• A. Osteoarthritis and osteoporosis
• B. Asthma and allergic rhinitis
• C. Benign prostatic hyperplasia and diabetes
• D. Hypertension and hyperlipidemia

Answer: (C)

Nocturia often stems from conditions that affect urine production or bladder storage at night. The best example pair is benign prostatic hyperplasia and diabetes. Benign prostatic hyperplasia can block urine flow and reduce the bladder’s ability to hold urine, leading to more nighttime voiding; treating the obstruction or reducing its effects helps the bladder store more urine and lowers the need to wake up to pee. Diabetes causes increased urine production at night (osmotic diuresis) when blood glucose is high; controlling blood glucose and managing diabetes lowers nighttime urine output. The other listed conditions don’t directly drive nocturnal urine production or bladder storage in the same way, so they’re not commonly targeted to reduce nocturia.
