IBD patients’ follow-ups are done at gastroenterology, internal medicine or pediatric outpatient clinics in hospitals, health care centers or other medical centers. IBD is diagnosed using biopsies taken from the intestinal wall in a colonoscopy. Colonoscopies are also done to follow up the response to treatment and later to find anaplasias that can develop into cancer.

The course of the illness and response to treatment is also followed up with laboratory tests from whole blood, blood serum, urine or stool samples. Laboratory tests can also detect potential co-morbidities.
