Inflammation of the abdominal muscles.
From Greek koilia (belly) + mys (muscle) + -itis (inflammation). The suffix -itis is one of medicine's most productive suffixes, added to any structure to indicate inflammation.
Every body part with '-itis' at the end is angry or inflamed—your abdominal muscles swelling up would make movement and breathing really uncomfortable!
