Feeling the stomach beating may be caused by physiological factors, but also may be caused by abdominal aortic aneurysm, stomach spasm, abdominal wall muscle spasm and other conditions. 1. Physiological factors: normal gastric peristalsis is usually not felt by the body, if there is a feeling that the stomach is throbbing may be touching the abdominal aortic pulsation, so the stomach is felt to be throbbing. 2. Abdominal aortic aneurysm: patients with abdominal aortic aneurysm can feel a throbbing mass when touching the abdomen, and the throbbing is consistent with the heartbeat, and the mass is generally round. 3. Stomach cramps: stomach cramps can be caused by cold in the abdomen, which can be manifested as if the stomach is throbbing, and usually accompanied by obvious abdominal cramps and other symptoms. 4. Abdominal wall muscle spasms: when the abdomen is stimulated by cold or excessive exercise, it may cause abdominal wall muscle spasms, resulting in a feeling as if the stomach is throbbing. If you are not sure why you feel your stomach throbbing, go to the hospital and ask your doctor to make a judgment.
