Gas and gurgling in the stomach may be caused by eating and talking, drinking a lot of carbonated beverages and pyloric obstruction. 1. Eating and talking: Talking a lot while eating can cause a lot of air to enter the digestive tract, and because eating stimulates peristalsis of the digestive tract, when the peristalsis of the digestive tract squeezes the air, there will be gas in the stomach, resulting in a gurgling sound. 2. Drinking a lot of carbonated beverages: If you drink a lot of carbonated beverages, it will stimulate the cells of the stomach lining to secrete stomach acid. These stomach acids not only decompose carbonated drinks to produce carbon dioxide gas, but also stimulate peristalsis of the digestive tract, and the gas hits the intestinal wall with the peristalsis of the digestive tract, which can cause gurgling and rumbling. 3. Pyloric obstruction: If the pylorus is obstructed due to localized edema, food cannot pass through the digestive tract smoothly, resulting in food staying in the stomach for a long time, and the food staying in the intestinal tract is decomposed by gas-producing bacteria, which can release gas, and when the gas produced by gastric contents hits the digestive tract, a gurgling sound will be emitted from the stomach, which is usually accompanied with abdominal pain, abdominal distension, and vomiting. It is recommended that patients with gas in the stomach and gurgling sound should go to regular hospitals in time to find out the cause of the disease under the guidance of professional physicians and then undergo targeted treatment.
