Early satiety refers to the feeling of being “full” when the amount of food eaten is less than the normal amount of food eaten, which indicates a problem with the stomach, or to be more specific, a problem with “gastric power”! When the proximal stomach’s ability to hold and store food decreases, and does not open properly after eating, the patient will experience a feeling of fullness, usually accompanied by belching, bloating, and even nausea and vomiting. Gastric power disorder caused by the following factors: 1, gastric secretion dysfunction: the human stomach wall has two kinds of cells with secretion function, one secretes digestive enzymes, the other secretes gastric acid. When the function of these cells decline, digestive enzymes and gastric acid secretion is also reduced, which will reflexively inhibit the contraction and peristalsis of the stomach muscles, resulting in gastric motility disorder. 2, mental and emotional changes: mental tension and emotional sadness can disrupt the electrical activity of the stomach, affecting the sympathetic nerve, which causes the gastric muscle contraction frequency is slow, the food in the stomach can not be discharged to the intestines in a timely manner, the formation of food and gas retention in the stomach, resulting in bloating, belching, nausea and many other symptoms. 3, functional dyspepsia: slow gastric emptying, causing a series of symptoms of indigestion, called “functional dyspepsia”. Because the proximal stomach to accommodate and store food function decreases, can not be normal diastolic after eating, the patient will feel full, usually accompanied by belching, bloating, and even nausea, vomiting and other symptoms. 4, eating improper: eating too much radish, potatoes, sweet potatoes, chestnuts and other foods. Overeating, overeating, so that the stomach load more than normal, the stomach muscle peristaltic force is not enough, the stomach can not be emptied on time, the accumulation of food in the stomach for too long, will lead to gastric power.
