Not eating meat will not cause gastric distress, which may be caused by physiological factors such as irregular diet, or pathological factors such as gastritis and gastric cancer, and can be treated with general treatment, medication such as omeprazole and atropine, and surgical treatment according to different etiologic factors. 1. Physiological factors: for example, frequent irregular eating or eating too much or too little, unbalanced secretion of gastric acid may also cause gastric distress. It can be treated without medication for the time being by improving life habits, such as regular diet and balanced nutrition. 2. Pathologic factors: (1) Gastritis: mostly acute or chronic inflammation of gastric mucosa. When the secretion of gastric acid increases, it will cause stomach difficulty and discomfort. Oral atropine or scopolamine can be taken for antispasmodic, and if there is Helicobacter pylori infection, clarithromycin, amoxicillin, omeprazole, pectin bismuth anti-Helicobacter pylori treatment can also be used in combination. (2) Gastric cancer: If middle-aged or old people have long-term hidden pain in stomach and history of gastric ulcer, they also need to consider gastric cancer. When the cancerous foci invade the surrounding normal gastric tissues and affect the normal digestive function, gastric pain and bloating and other discomforts may also occur. Gastroscopy or histopathological examination can be used to make a clear diagnosis. If necessary, surgical treatments such as radical gastrectomy and most of stomach resection for gastric cancer are feasible, and the need for chemotherapy can be determined according to postoperative pathological results. If you often have symptoms such as stomach discomfort, stomach pain and bloating, it is recommended to consult a doctor in time and diagnose and analyze them through gastroscopy, esophageal X-ray barium meal and laboratory tests under the guidance of a professional doctor, and then treat the symptoms in combination with the causes of the disease.
