Nighttime Incontinence in Adults

Quick answer: Adult bedwetting (nocturnal enuresis) and night-time leaks can be caused by an overactive bladder, prostate problems, sleep apnea, diabetes, some medications, or making more urine at night. See a doctor to find the cause. Meanwhile, overnight briefs or underwear, booster pads, underpads and external catheters for men can keep you dry and sleeping well.

Why do adults leak at night?

  • Overactive bladder: urgency that wakes you, sometimes too late
  • Nocturnal polyuria: producing more urine at night, common with age and heart or kidney conditions
  • Enlarged prostate: the bladder doesn't empty well before bed
  • Sleep apnea: linked to increased night-time urine
  • Diabetes, medications (such as diuretics) and evening fluids, especially caffeine and alcohol
  • Neurological conditions that affect bladder signals

New bedwetting in an adult should always be checked by a doctor.

Habits that can help

  • Drink most of your fluids earlier in the day.
  • Cut caffeine and alcohol in the evening.
  • Empty your bladder right before bed, then try again a few minutes later (double voiding).
  • If your legs swell, raise them in the evening so fluid is processed before bedtime.
  • Keep a clear, lit path to the toilet, or use a bedside commode.

What are the best overnight products?

Product Why it helps at night
Overnight briefs (tab-style) Highest absorbency; easiest to change in bed
Overnight protective underwear High absorbency in a pull-on style
Booster pads Add capacity inside your brief or underwear
Underpads (washable or disposable) Protect sheets and mattress from leaks
External catheters for men, such as AFEX Collect urine away from the body, so no wet product overnight

As one of our customers' wives shared, an external system meant neither of them had to wake up every few hours for changes.

Frequently asked questions

Is it normal for older adults to wet the bed?

It's common, but it isn't something to simply accept. A doctor can often find a treatable cause.

What is the most absorbent adult diaper for overnight?

Look for briefs labelled overnight or maximum absorbency, and make sure the size is right, since a poor fit causes more leaks than low absorbency.

How do I stop leaking out the side at night?

Check the size, make sure leg gathers sit in the groin crease, and add a booster pad. Side sleepers may need a product with higher leg barriers.

Can men avoid wearing a diaper at night?

Many men use an external collection system instead. See External Catheter vs. Condom Catheter vs. Pads.
