China is a country with high incidence of gastric cancer, more than half of the new gastric cancers in the world are in China, and many people die from gastric cancer every year in China, accounting for about 1/5 of all tumor mortality. according to relevant information, the detection rate of early gastric cancer patients in China is only about 5-10%, and most patients are already in the middle and late stages when they are found. Timely gastroscopy can visualize the changes of mucosa and detect different diseases such as gastric ulcer, inflammation, tumor and polyps. A. Why do gastroscopy Diseases are very similar to the weather, when it is sunny it usually does not suddenly rain, but first gradually turns from sunny to cloudy, and only after that it rains. We often see that people who have stomach pain or stomach discomfort think that stomach pain or stomach discomfort is a trivial matter, so they can take some medicine at most to reduce the symptoms and forget about it, and they don’t pay attention to the symptoms and delay gastroscopy again and again, or they are afraid of it. Because the postoperative survival rate of early gastric cancer is more than 95%, while the survival rate of mid-stage gastric cancer is only 20%. The role of early diagnosis and early treatment cannot be overstated. Gastroscopy can clarify whether there are ulcers, active inflammation, precancerous lesions, tumors, polyps and other lesions, and it can also directly take lesion tissues for cytology and pathology examination to obtain pathological diagnostic evidence. Once again, we urge you to perform gastroscopy in a timely manner according to your specific condition and doctor’s recommendation, and not to wait until your condition deteriorates before considering gastroscopy. In general, we recommend people over 40 years old to undergo gastroscopy every one to two years. People with symptoms such as upper abdominal discomfort, black stool, loss of appetite and weight loss, or those with family history of stomach cancer or living in areas with high incidence of stomach cancer should pay more attention to gastroscopy. For patients with previous history of chronic atrophic gastritis, gastric polyps and gastric mucosal intestinal disease, it is also better to have regular gastroscopy for early follow-up judgment of the disease if there is no change in the condition. Third, do gastroscopy in the end pain I believe that many people have heard friends who have done gastroscopy recall how “scary” gastroscopy is, and have a psychological burden or concern about gastroscopy. But in fact, the examination is not as painful as you might think. Simply put, a gastroscopy is simply a tube that is inserted into the stomach and a mirror-like probe at the bottom is used to see the changes in the stomach. The process is simple but not rough, there may be a little discomfort, often the patient has not reacted, the examination has been done, for the gag reflex is particularly sensitive or have a fear of people can choose to anesthesia under the gastroscope, so wake up gastroscopy is over.
