The symptoms of chronic gastric disease are often caused by chronic gastric disease, intestinal obstruction, gastric tumor, irritable bowel syndrome, swallowing gas, etc. The cause can be clarified and treated symptomatically. 1, chronic gastric disease: the symptoms of chronic gastric disease are triggered by the prolonged acute gastritis, excessive smoking and irregular diet, long-term use of drugs that damage the gastric mucosa, which can be manifested as epigastric fullness and discomfort during fasting, and should be treated symptomatically according to the cause. If it is due to drug factors, suspension of medication should be instructed. If it is caused by smoking and alcohol, then smoking and alcohol should be stopped. If it is due to H. pylori infection, it should be treated with quadruple therapy, i.e. bismuth + two antibiotics + proton pump inhibitor. Among the proton pump inhibitors, omeprazole, lansoprazole, pantoprazole, rabeprazole, estramiprazole, eprazole, etc., commonly used antibiotics are metronidazole, clarithromycin, levofloxacin, amoxicillin, furazolidone, tetracycline, and bismuth can be used as pectin bismuth, bismuth potassium citrate, etc.; 2. Intestinal obstruction: when intestinal obstruction occurs, it can lead to abdominal distention without eating, and abdominal pain and other symptoms. Patients in the acute phase of intestinal obstruction need to fast and abstain from water, and intravenous drip of saline, potassium chloride injection, glucose injection, etc. to supplement the water electrolytes and nutrients required by the body. At the same time, gastrointestinal decompression is performed to draw out the gas and fluid accumulated in the gastrointestinal tract, and broad-spectrum antibiotics, such as cephalosporin and penicillin, can be used under the guidance of the doctor in case of infection. Patients with poor conservative treatment or more serious obstruction need to undergo surgery to release the obstruction. Patients usually need to pay attention to a reasonable diet, based on light, easily digestible food, avoid greasy, spicy and irritating food; 3, irritable bowel syndrome: irritable bowel syndrome patients have visceral hypersensitivity, the pain threshold for colorectal dilation is significantly lower than normal, more likely to produce abdominal distension, abdominal pain and other symptoms. Attention needs to be paid to adjusting dietary habits, avoiding excessive fat and stimulating foods such as coffee, strong tea, alcohol, etc., and reducing the intake of gas-producing foods such as dairy products, soybeans, lentils, etc.; 4. Aerophagia: Patients with aerophagia swallow air frequently, which causes a feeling of fullness in the epigastrium. Dietary adjustments include avoiding hard candy or chewing gum, eating slowly, avoiding soda, quitting the bad habit of swallowing air, and applying pro-gastrointestinal motility drugs, such as cisapride, to promote the discharge of swallowed gas when abdominal distension is severe; 5, stomach tumors: common ones are cysts, adenomas, smooth muscle tumors, malignant tumors including gastric cancer and mesenchymal tumors, etc., which can cause abdominal fullness and discomfort, and should be actively improved with relevant examinations, and then according to The relevant examination should be actively improved, and then symptomatic treatment should be carried out according to the cause.
