Almost all patients with FMF experience abdominal episodes. Abdominal pain develops, and may progress to peritonitis. Frequently the clinical presentation is consistent with appendicitis or cholecystitis, so patients commonly undergo appendectomies and cholecystectomies because the abdominal episodes of FMF are not recognized as such. The symptoms may also mimic renal colic.

In many cases, patients develop constipation during the attack and diarrhea after the attack resolves.

Even with recurrent attacks, adhesions are rare.
