If you've ever woken up to a nighttime accident after consuming alcohol or caffeine, you might be wondering whether these drinks play a role in adult bedwetting. The truth is, both alcohol and caffeine are known to affect bladder function, potentially leading to nocturnal enuresis (bedwetting) in adults.
While occasional incidents might not seem concerning, frequent episodes could indicate an underlying issue—or simply be a result of how these substances interact with your body.
In this blog, we’ll explore how alcohol and caffeine impact bladder control and what steps you can take to prevent nighttime accidents.
How Does Alcohol Affect Bladder Control?
Suppresses Hormones
Alcohol is a diuretic, meaning it increases urine production by suppressing the antidiuretic hormone (ADH) produced by the brain. On a normal day, ADH signals the kidneys to regulate urine production. Alcohol interferes with this process, resulting in increased urine output and a greater likelihood of bedwetting.
Affects Muscle Function
Alcohol relaxes muscles throughout the body, including those controlling the bladder. It also depresses the central nervous system, making it harder to recognise the need to urinate and wake up in time—potentially leading to nighttime accidents.
Irritates the Bladder Lining
Certain types of alcohol, such as beer and spirits, can irritate the bladder lining, increasing urgency and reducing control. Sugary alcoholic drinks are especially likely to overstimulate the bladder, as sugar can act as a bladder stimulant.
How Does Caffeine Affect Bladder Control?
Increases Urine Production
Like alcohol, caffeine is a diuretic. It interferes with the kidneys' ability to reabsorb water, causing the bladder to fill more quickly and increasing the chance of nighttime accidents.
Irritates the Bladder Muscle
Caffeine can irritate the smooth muscle of the bladder, increasing sensitivity and causing involuntary spasms or contractions. Beverages such as coffee, tea, energy drinks, and fizzy drinks can all contribute to urgency, frequency, and loss of control—especially when consumed later in the day.
Affects Sleep
Caffeine is a stimulant that disrupts sleep by making it harder to fall asleep and stay asleep. Poor sleep hygiene can affect hormonal balance and kidney function, which may lead to increased nighttime urination and potential accidents.
How to Manage Bedwetting Linked to Alcohol & Caffeine
1. Adjust Your Drinking Habits
- Limit alcohol and caffeine intake, especially later in the day.
- Choose non-diuretic beverages like herbal teas, squash, or water.
- Try switching to decaffeinated drinks if you notice sensitivity.
2. Regulate Fluid Intake Before Bed
- Reduce all liquid consumption in the hours before bedtime.
- Avoid alcohol or caffeine close to sleeping hours.
- Fully empty your bladder before going to bed.
3. Strengthen Bladder Control
Pelvic floor exercises can improve bladder function, and bladder training—such as increasing time between bathroom visits—can build control and reduce urgency during the night.
4. Use Protective Bedding for Peace of Mind

If symptoms continue despite lifestyle changes, consult your GP. A medical professional can check for underlying issues and recommend tailored treatments.
Final Thoughts
Alcohol and caffeine both affect bladder function and may contribute to adult bedwetting. If you often experience nighttime accidents after drinking these substances, consider adjusting your habits—especially in the afternoon and evening.
