Under normal circumstances, when people eat, the stomach muscles will relax and expand the stomach capacity to accommodate the swallowed food. After digestion, the stomach muscles will slowly contract, pushing food down into the duodenum and small intestine. The stomach will still maintain a slight peristalsis on an empty stomach, helping to expel the liquid in the stomach.
But when the stomach peristalsis is poor, the stomach does not expand as usual when eating, even if the patient does not eat much, he will soon feel "full" and "unable to eat"; Coupled with the slow contraction of stomach muscles, food stays in the stomach for a long time, delaying satiety and stagnation; Even on an empty stomach, stomach muscles don't know how to contract, which often makes patients feel bloated. This condition is indigestion.
Extended data:
Dyspepsia is mainly divided into functional and structural (or organic), with the former accounting for about 80%. The cause of functional dyspepsia is unknown, and there is usually no evidence to prove that organ diseases are the cause [3], but it may be related to the pace of life and eating habits, such as mental stress, overeating, irregular diet, lack of exercise, smoking, alcoholism and so on.
Structural dyspepsia is related to other digestive diseases, including gastric ulcer, duodenal ulcer and gastric cancer.
