Left abdominal pain, bowel sounds and many farts may be caused by indigestion, intestinal obstruction and colitis. 1. Indigestion: Frequent overeating and frequent insomnia and anxiety can easily lead to endocrine and nerve dysfunction, resulting in indigestion and causing the symptoms of hidden pain in the left middle abdomen, intestinal chirping and many farts. 2. Intestinal obstruction: If the patient has obvious paroxysmal pain in the abdomen, vomiting, abdominal distension, symptoms of intestinal sounds and farting, and no bowel movement, there may be intestinal obstruction, and the patient should consult the doctor in time for further examination. 3. Colitis: Colitis mainly involves the mucosa of the large intestine. In the active phase, the intestinal mucosa may show persistent and diffuse erythema, mucosal congestion, roughness or granular appearance. Under the stimulation of inflammation, intestinal peristalsis will increase and intestinal spasm will occur at the same time. In addition to the increased frequency of stools, the normal sound of intestinal peristalsis will be elevated, so there will be a noticeable bowel sound and a high number of farts, especially in patients who are thin. If you have symptoms of left abdominal pain, intestinal sounds and farting, you should go to the hospital for examination to clarify the cause.
