Patients with long-term gastric distension may progress to gastric cancer, so they need to pay enough attention to it. Stomach cancer mainly occurs in the sinus region of the stomach, and gastric distension is one of the manifestations of stomach cancer. In addition, patients may also suffer from upper abdominal pain, acid reflux, belching and burning sensation. If the disease continues to develop, the peristaltic function of the gastrointestinal tract will be affected, and the patient will thus show obvious flatulence. In addition, ulcerative colitis and chronic atrophic gastritis can also lead to poor peristaltic function of the stomach and intestines, which in turn leads to abdominal distension and abdominal pain symptoms. If the above diseases are not treated in time, long-term stimulation of the stomach will deteriorate into stomach cancer over time. It is recommended that people with long-term gastric distension should go to the gastroenterology department of a hospital for treatment in a timely manner, avoid eating too much in daily life, and keep each meal at 7-8 minutes full.
