There is always something in the stomach to consider the possibility of suffering from indigestion, stomach cancer and other diseases. 1. Indigestion: When indigestion occurs, the peristalsis of the gastrointestinal tract slows down. When food is stored in the gastrointestinal tract for a long time, you may feel that there is always something in your stomach. 2. Gastric cancer: early gastric cancer may not have any sign, while the most common sign of middle and late stage cancer is pressure pain in the upper abdomen. 1/3 of patients may find a mass in the upper abdomen, which is firm and irregular in texture. Stomach cancer is a malignant lesion, and malignant tissues keep growing and reproducing, which may cause local irritation and distant metastasis. There is always something in the stomach, which may be caused by other reasons. If the symptoms continue to be unrelieved, it is recommended to consult a doctor in time, to clarify the cause of the disease under the doctor’s guidance and to take targeted treatment, and do not take medicine by yourself, so as to avoid delaying the condition.
