bloating is such a common symptom that can be due to irritable bowels, bad food, too much alcohol consumption, metabolic derangements such as low thyroid, or some process irritating the abdomen such as
kidney stones, inflammation of appendix, colon, or growths in the gyn system.
In the process of sorting out persistent and unexplained bloating, a careful gyn evaluation should be done.
This includes pelvic exam, rectal, and transvaginal pelvic ultrasound.
