Abdominal attacks happen when the intestinal wall swells. They can cause pain, nausea, vomiting, and diarrhea. The swelling can be visibly noticeable. Your belly might appear unusually large and bloated. Sometimes, women who experience an abdominal attack look pregnant when they aren’t. Abdominal attacks are often misdiagnosed as other health problems, such as appendicitis or  irritable bowel syndrome (IBS).
