A person with AA usually develops bald patches although generalized thinning or complete baldness may also occur. In most cases, children with AA may have a few small patches that disappear without treatment within one year. AA can be treated with topical steroids or topical irritants but in young children these treatments are usually not practical. Gastrointestinal problems tend to be more common in children with Down syndrome than in the normal population, however most of these conditions are rare. Children with this condition can become extremely constipated.
Severe cases can be life threatening if left untreated.
Hirschsprung's is normally treated by surgically removing the part of the bowel that does not function correctly. Depending on the amount of constriction, this can be a serious medical emergency. This condition is normally treated surgically. In duodenal atresia, the first part of the intestine where it connects to the stomach is completely blocked off. Since no food can pass from the stomach into the intestines, this condition must be treated immediately by surgically removing the blocked part of the intestine.
