Signs and Symptoms
Some children with polyps will develop symptoms while others will develop no signs at all. The typical presentation of colorectal polyps at any age is painless, bright red rectal bleeding with bowel movements. This is frequently associated with other signs and symptoms that can include diarrhea, cramps or sharp pains in the stomach, polyp tissue coming out of the rectum (prolapse), weight loss and loss of energy.
Children with familial adenomatous polyposis (FAP), the most common of all polyposis syndromes, may also develop polyps in other parts of their digestive system like the stomach and small intestine. They may also get small lumps and bumps on their bones or skin or have extra or missing teeth. In most cases, however, you can not tell who has FAP just by looking at them. How polyps present themselves in children is largely dependent on the location and number of polyps.
