Bloating and burping upwards all the time is not necessarily stomach cancer. Flatulence and hiccups are usually caused by the lack of gastric power, and may also be caused by gastritis. Most patients with early stage gastric cancer have no obvious symptoms, while a few have nausea, vomiting, flatulence or upper gastrointestinal symptoms similar to ulcer disease. For occasional hiccups and flatulence, most of them are caused by indigestion or gastric ulcer. Flatulence that keeps going up may also be caused by stomach bleeding, stomach cramps or improper diet. Patients who have flatulence and burping upwards can usually get relief through medication. If the symptoms recur after medication, gastroscopy can be used to further clarify the diagnosis and treat the symptoms. Therefore, flatulence and frequent upward burping may not necessarily be stomach cancer. In case of frequent flatulence in the stomach that cannot be relieved, it is necessary to pay attention to it and actively conduct examination and treatment. With the advancement of medical technology nowadays, many selected diseases can be cured at early detection.
