Bloating after eating is caused by gastric prolapse, indigestion, lactose intolerance, and intake of irritating foods. Some people physically have hypogastric prolapse, which aggravates the disease after eating and affects the peristaltic function of the stomach, and the abdomen becomes bloated after eating. When the human body has indigestion, there is insufficient secretion of digestive juices in the stomach after eating, so that the ingested food cannot be quickly decomposed, putrefied and emptied, and the food will be inhibited in the stomach for a long time will appear bloated feeling. When the body is lactose intolerant, once the food containing lactose is consumed, it will not be able to break down the lactose, resulting in a feeling of intestinal flatulence. When eating try to avoid eating irritating foods, such as chili peppers and cold drinks, which can cause irritation to the mucous membrane of the digestive system and even lead to impaired function, so a feeling of abdominal distention can occur.
