Ive read it could just be gas, Ive had a little or it could be Abdominal Aortic Aneurysms. Or something else. I just want to have an idea of whats going on with my stomach and digestive system instead of always worrying about what I can or cant eat or even when I can eat. Please help I really want a normal stomach : or just to find out whats wrong so I can fix it.  <response>: Welcome to Chat Doctor .1. Fist you need to start getting investigations done to find out the cause.2. If you are my patient I would first examine you and ask for an ultrasound abdomen pelvis done - which will help me to narrow down my diagnosis.3. Furthere I might go for an endoscopy to see if there are any ulcers erosion.4. Similar symptoms are seen in the ischemic bowel disease, colitis.5. After narrowing the diagnosis the treatment will start. Hope it helps you. Wish you a good health. Anything to ask ? Do not hesitate. Thank you.
