Lower abdominal distension and pain are not always due to “gas” in the stomach. In addition, inflammation and mechanical stimulation of the lower abdominal viscera, such as enteritis and appendicitis, may also cause lower abdominal distension and pain. If, due to intestinal spasm, obstruction and other reasons, the intestine is not open and gas accumulation occurs, it may indeed also cause lower abdominal distension and pain.
In short, if the symptom of lower abdominal distension lasts for a long time, it is necessary to go to the hospital in time to clarify the cause.
