Constipation is a common problem for children. The bowel is very close to the bladder in the body. The bladder is not able to expand and hold urine very well when a child has a large amount of stool in their rectum or bowel. Constipation can cause the bladder to have spasms and not empty completely. Bladder symptoms that can occur with constipation are day and night wetting, urinary tract infections, frequency, urgency and pain with urination. It is very important to treat a child's constipation so that their bladder symptoms can improve. For the bladder to be healthy, a child should have a soft, easy to pass bowel movement at least once a day.
