How is Hirschsprungs disease diagnosed?
A health professional usually first suspects Hirschsprung’s disease based on descriptions of your child’s symptoms and the results of a physical examination. A rectal biopsy, abdominal X-ray, barium enema, and other tests may be done to confirm diagnosis. Though Hirschsprung’s disease is present from birth (congenital), it may not be diagnosed until months or years later. However, most children born with this disease are diagnosed within the first year of life. In rare cases, an undiagnosed or untreated case can become life-threatening.
