What causes a rumbling stomach?

　　A rumbling or gurgling stomach usually refers to abdominal bowel sounds. Abdominal bowel sounds are a common digestive phenomenon, primarily caused by factors such as hunger, excessive intestinal gas, indigestion, intestinal flora imbalance, and acute gastroenteritis. If symptoms persist or become severe, it is recommended to seek medical attention promptly. Specific details are as follows:

　　1. Hunger

　　When the body is hungry, the brain triggers the secretion of digestive juices and significantly increases gastrointestinal motility, leading to the occurrence of abdominal bowel sounds. This condition typically resolves after eating.

　　2. Excessive Intestinal Gas

　　Eating too quickly, talking while eating, or consuming excessive amounts of gas-producing foods may lead to an accumulation of intestinal gas, resulting in abdominal bowel sounds.

　　3. Indigestion

　　When suffering from indigestion, gastrointestinal motility is weakened, prolonging the retention time of food in the stomach and intestines. Bacterial breakdown and fermentation of food produce large amounts of gas, causing the aforementioned symptoms.

　　4. Intestinal Flora Imbalance

　　When the balance of gut microbiota is disrupted, various bacteria ferment within the intestine and generate substantial amounts of gas, also leading to such bowel sounds.

　　5. Acute Gastroenteritis

　　Gastrointestinal inflammation caused by bacterial or viral infections can irritate the gastrointestinal mucosa, increasing intestinal motility and thereby producing abdominal bowel sounds.

　　Patients should maintain a light diet and ensure adequate sleep to support recovery.
