Walking stomach pain may be caused by pyloric obstruction, stomach cancer, angina and other factors. 1. Pyloric obstruction: The food in the stomach needs to pass through the pylorus in order to enter the intestines, and if the pylorus is obstructed, it may lead to a large amount of food stored in the stomach. If the pylorus is obstructed, it may lead to a large amount of food stored in the stomach. When walking, with the swaying of the human body, the food may cause stimulation to the stomach wall, which will lead to stomach pain when walking. 2. Stomach cancer: Stomach cancer is a kind of malignant tumor that occurs in the stomach, and the tumor cells can cause damage to the stomach wall. In the process of walking, the tumor cells may pull on the damaged stomach wall, thus leading to stomach pain when walking. 3. Angina: When walking, the heart does more work and the demand for oxygen increases, which may lead to angina due to insufficient oxygen supply. When angina occurs, there may be radiating pain in the upper abdomen, which may also be manifested as walking stomach pain. When walking stomach pain occurs, you should consult a doctor in time, complete X-ray examination, gastroscopy, electrocardiogram and other tests under the guidance of the doctor, to clarify the cause of the disease, and actively treat it.
