I often have a stomachache, but how is it that I don't have diarrhea?

There are many causes of abdominal pain, such as gastritis, pancreatitis, cholecystitis, appendicitis, colitis, etc., which need to be considered. If it is a woman, it does not rule out the possibility of gynecological diseases, including uterine fibroids, pelvic inflammation, endometritis, appendicitis, etc., which need to be treated according to the cause.
