Insufficient gastric power refers to insufficient peristaltic force of contraction of the stomach muscles, thus causing indigestion symptoms such as epigastric distention, early satiety, bloating after meals, loss of appetite, nausea and vomiting. Insufficient gastric power can be caused by mental factors, bad habits, gastric secretion dysfunction and other reasons, need to be dealt with according to the specific reasons. 1, mental factors: long-term mental tension, anxiety, depression, grief, can affect the sympathetic nerve, which causes the stomach muscle contraction frequency is slow, peristaltic force is insufficient, you can read books, listen to music, go out to play, relieve the state of tension, relax. Usually communicate with family and friends, venting anxiety, depression and other bad emotions, can gradually alleviate the lack of gastric power; 2, bad habits: improper diet, such as eating indigestible food, gas-producing food and overeating, can increase the burden on the stomach, resulting in food in the stomach can not be emptied on time, which in turn affects the gastric power. In addition, smoking and drinking habits can cause relaxation of the pyloric sphincter and damage to the gastric mucosa, leading to bile reflux and gastric motility disorders. Usually pay attention to regular eating, avoid overeating, quit smoking and limit alcohol; 3, gastric secretion dysfunction: when the secretion function of gastric wall cells decreases, digestive enzymes and gastric acid secretion decreases, resulting in reflex inhibition of gastric muscle contraction and peristalsis, resulting in gastric motility deficiency, can use digestive enzymes and pro-gastric motility drugs for improvement, such as domperidone, mosapride, etc.; 4, gastrointestinal tract diseases: some gastrointestinal tract diseases Such as reflux esophagitis, bile reflux gastritis, simple gastritis, peptic ulcer, etc., may affect gastric motility due to inflammatory stimulation, resulting in gastric hypokinesis, which requires acid suppression therapy as well as gastric motivation therapy, common drugs for cimetidine, ranitidine, famotidine, aluminum thioglycollate, magnesium aluminum carbonate, etc.
