Question for Betty.
So, I'm a 19 year old male and I haven't done this since I was little, but I wet the bed while I was sleeping last night.  This only happened to me one other time 2 years ago.  I didn't have too much fluids before I went to bed, and I do not drink, smoke, or do drugs.  Should I be worried?  I feel fine but it's humiliating.
Betty's Answer.
Thanks for sharing your concern.  Bed wetting or nocturnal enuresis in an adult may be a symptom of a health concern that needs evaluation by a health care provider.  Your elimination of common causes of enuresis such as excessive fluids, excessive alcohol, and use of certain drugs, is helpful.  Also your history of enuresis as a small child (very common), and no further problems for many years is helpful.  
Other causes of enuresis may include a urinary tract infection, prostate infection, sexually transmitted infection or even sleep apnea.
I would encourage you to schedule an appointment with a health care provider for evaluation and treatment.  If you are an eligible UAA student, you may call 907-786-4040 to schedule an appointment.
