My boyfriend recently diagnosed w/ibs. At followup liver enzymes # high. Tomorrow ultrasound to gall blad, pancreas, bio duct. Is this serious?

Was colonoscopy done. Depending on what liver tests are elevated and what they find on ultrasound, additional tests may be needed. How was the diagnosis of irritable bowel syndrome made? Did he have a colonoscopy? A diagnosis of ulcerative colitis should be ruled out if there is evidence of elevated alkaline phosphatase without gallstones, since primary sclerosing cholangitis is associated with this condition.
