Occult pain in the stomach may be caused by indigestion, gastritis, gastric malignant tumor and so on. You can take gastrointestinal stimulants, acid-suppressing drugs, gastric mucosa protectants and targeted drugs. 1. Dyspepsia: you can take drugs to promote gastrointestinal dynamics such as domperidone tablets, mosapride and other drugs to regulate the gastrointestinal flora such as lactobacilli, bifidobacteria, etc., and you can also use the compound digestive enzymes to assist digestion. 2. Gastritis: acid inhibitors such as omeprazole, ranitidine and other drugs, gastric mucosal protectants such as bismuth potassium citrate, aluminum hydroxide gel. If there is a combination of pylori infection, you also need to use quadruple drugs for sterilization treatment. 3. Gastric malignant tumor: if gastric cancer in early stage can also appear unremarkable hidden pain, oral targeted drugs such as trastuzumab can be used to assist the treatment. Patients should go to the hospital as soon as possible to improve relevant examinations such as gastroscopy to clarify the cause of the disease. The drugs mentioned above should be taken under the guidance of professional doctors.
