Bladder leaks at night (called nocturnal incontinence) are different from nocturia, where you simply wake up often to use the bathroom. With nocturnal incontinence, your bladder empties while you sleep, sometimes without you realizing it.
There are a few common causes: weak pelvic floor muscles, issues with the bladder’s sphincter muscle, or nerve-related conditions that interrupt communication between your brain and bladder. In some cases, excessive urine production (known as polyuria) can also contribute to nighttime leaks.
Lifestyle factors matter too. Caffeine, alcohol, and diuretics can irritate the bladder or increase urine production, and drinking too much fluid late at night can add to the problem. Small changes can help with managing nocturnal incontinence.
If you’re experiencing nighttime leaks, understanding what’s behind them is the first step toward reducing bladder leaks, finding relief and getting a better night’s sleep.
