Bloating of the stomach after eating is considered to be obesity of the small abdomen, which is more common in life. The reason for this is related to the patient’s physique, over-nutrition and poor lifestyle. It is caused by the accumulation of excess fat in the small abdomen, which can cause the intra-abdominal pressure in the upper abdomen to increase after eating, and then cause the small abdomen to become distended. Abdominal obesity affects aesthetics and increases the risk of cardiovascular diseases. It is recommended to consume the excess fat in the abdomen by controlling diet and increasing the amount of exercise, and not to blindly take weight-loss drugs.
