Patients with early-stage gastric cancer generally have no obvious symptoms, and in a few cases, they may experience nausea, vomiting, and other symptoms similar to upper gastrointestinal ulcers.
Patients with advanced gastric cancer have a reduced overall health status due to the disease, and may experience varying degrees of difficulty eating, loss of appetite, and significant pain.
For some postoperative patients with gastric cancer, it is recommended that they eat fewer and more frequent meals, never overeat, and choose the amount of food they want to eat based on their body’s ability to tolerate it.
