All of our tumor patients, including gastric cancer patients, will have some symptoms proving that the patients are in poorer condition when they are in the terminal stage, and one of the main ones is caused by the tumor, for example, in gastric cancer, the patients often have the symptom of upper gastrointestinal obstruction due to the large mass in the stomach, that is, the difficulty in eating, the vomiting or the lack of defecation or exhaustion of the stomach after eating, and this kind of situation. In addition, due to tumor metastasis, such as a series of symptoms caused by abdominal metastasis, lower gastrointestinal obstruction often occurs after abdominal metastasis. Another one is the large amount of ascites, due to these ascites, digestive tract obstruction, the patient can not eat, a large amount of peritoneal fluid drainage, the loss of excessive nutrition, will cause the patient extreme wasting, that is, malaise. In addition, it is the failure of organ function caused by some metastatic foci, such as lung metastasis, liver metastasis caused by this respiratory function failure, liver function failure. In addition, due to the secretion of more active substances by tumor tissues, these substances will attack multiple organs in the body, resulting in cardiac failure and renal failure. We will find that patients with terminal tumors have difficulty in eating, defecation or multiple organ failure.
