Bed-wetting in adults, also known as nocturnal enuresis, is an involuntary release of urine during sleep. While it is more common in children, it can also affect adults and may be a symptom of an underlying medical condition. Some of the possible causes of bed-wetting in adults include:

• Hormonal imbalances: A hormone called antidiuretic hormone (ADH) slows the kidneys production of urine while you sleep. In people with enuresis, this hormone is not produced in significant enough quantities to slow the production of urine, which often leads to bed-wetting. This can be a symptom of both Type I and Type II Diabetes.

• Small bladder: People who suffer from enuresis can also have a smaller functional bladder capacity, meaning the amount of urine they can hold before the bladder sends a signal to the brain that its full is smaller than average. Coupled with overactive bladder or bladder instability, this can lead to bed-wetting.

• Medications: Some medicines like antipsychotics and sleeping pills can irritate the bladder and cause bed-wetting.

• Stress: Stress or anxiety can sometimes cause people to wet the bed.

• Other health issues: Bed-wetting may also be due to conditions that affect the bodys ability to store and hold urine. For instance, bladder cancer and prostate cancer can cause it. So can diseases of the brain and spine, such as a seizure disorder, multiple sclerosis, or Parkinsons disease. Other possible causes include blocked urethra, constipation, urinary tract infection, urinary tract stones, anatomical abnormalities, urinary tract calculi, prostate enlargement, bladder cancer, or obstructive sleep apnea.

If you are experiencing bed-wetting as an adult, it is important to see a doctor for a medical evaluation to determine the underlying cause and appropriate treatment.
