Burping and farting may not necessarily be caused by stomach cancer, but also by indigestion and gallbladder disease, so specific analysis is needed. Generally speaking, hiccups and farts are mostly caused by chronic gastritis, gallbladder disease and other diseases, and some patients may also have symptoms such as upper abdominal fullness and unformed stools. Early stage of gastric cancer usually does not have obvious discomfort symptoms, but a few patients may have indigestion, fullness and discomfort, slight pain in upper abdomen. Since the symptoms of digestive system diseases are more similar, patients with more severe symptoms or those who are especially worried that they are suffering from stomach cancer can visit gastroenterology department to clarify the cause. Patients should pay attention to light diet, not to overeat, pay attention to keep warm and avoid getting cold.
