At present, as you said, this symptom has a lot to do with gastritis, especially with obvious postprandial stomach pain. If there are ulcers, this symptom is relatively more obvious, and it needs to be treated with corresponding drugs, such as antacids, drugs to protect gastric mucosa, drugs to improve gastrointestinal function, etc. The commonly used drugs are omeprazole, Colloidal Pectin Secret Capsule, Motiline, etc. It is best to adjust your eating habits, eat less spicy and greasy food, avoid overeating, and go to the digestive department for gastroscopy if convenient.
