Hello, my name is Wang Dafu, a Chinese doctor. In clinical treatment research, I think the cause of this disease is mainly caused by five products. This disease is a chronic gastritis. May be accompanied by erosion, bloody sputum, oozing blood, bile reflux and gastric polyps. Its disease is under the heart. Refers to the upper abdomen, heart socket stuffy, aggravated after eating, flatulence and pain. The main clinical manifestations are dyspepsia and epigastric fullness and discomfort. Especially when you are in a bad mood after dinner. Irregular upper abdomen, dull pain, swelling pain in ribs and back, burping, pantothenic acid and heartburn. Gross. Vomiting can also lead to other functional diseases. Such as anemia, dizziness, tinnitus, dry eyes, insomnia, dreaminess, forgetfulness, backache and leg weakness, irregular menstruation in women, fatigue in men and skin lesions. Due to chronic atrophic gastritis, this chronic disease is hidden and long-term. Often ignored by patients, the gastric mucosa gradually changes, the mucosal layer becomes thinner and the gastric gland cells undergo morphological changes. Therefore, the patient was diagnosed as mild, moderate and severe atrophic gastritis with intestinal metaplasia and epithelial hyperplasia or atypical hyperplasia. Could be precancerous lesions. So once again remind patients to pay more attention to prevention and treatment. Don't delay the illness. Be sure to pay close attention to treatment.
