Bed wetting is a very complex issue with many know causes and some not so know. As we see from responses here and other places The causes are many and encompass many medical specialty's, so it is no wonder why so few doctors truly understand bed wetting. I believe the causes vary widely thru various age groups. Certainly a 5 year old may not have the same causes as a 45 year old, but sometimes they may. If this sounds confusing, it is, because it is. Consider some of the known cures and causes. Drugs, surgery,sleep modification, diet change, allergies, chiropractic, neurological implications, psychological issues, birth defects, prostate care, child birth, heredity, etc. You would need a doctor well versed in many specialties to cure some of the difficult enuresis cases. Did I mention a doctor that is really dedicated.
