A grumbling stomach is a sign that the body’s gastrointestinal motility is more active. It can be caused by functional reasons, such as before hunger, peristalsis may be enhanced, the abdomen is cold and eating more stimulating food, causing functional peristalsis to increase. It can also be caused by pathological reasons, the more common gastrointestinal tract has acute inflammation, ulcers, tuberculosis, and even tumors, it will lead to increased gastrointestinal exudate, stimulating the gastrointestinal tract, resulting in increased peristalsis. To clarify which cause, it is recommended to go to the hospital for further examination, and if necessary, gastroscopy will be more clear.
