Which strategy can reduce nocturia?

• A. Increase evening fluid intake to prevent dehydration
• B. Limit evening fluids and avoid caffeine/alcohol late in the day
• C. Schedule a middle-of-the-night alarm to void
• D. Use diuretics at bedtime

Answer: (B)

Nocturia happens when the amount of urine produced during sleep is more than the bladder can hold or the bladder becomes more active at night. A key way to reduce it is to limit what reaches the bladder in the evening and avoid substances that boost urine production or irritate the bladder. Limiting fluids in the hours before bed and skipping caffeine or alcohol late in the day lowers nighttime urine output and reduces bladder stimulation, helping you sleep through the night. Increasing evening fluids would raise the bladder’s overnight load. Scheduling a middle-of-the-night alarm doesn’t change how much urine is made; it just causes awakenings. Using diuretics at bedtime increases urine production at night and would worsen nocturia.
