Many people are afraid of gastroscopy and often encounter a fear of gastroscopy in outpatient clinics, but why do doctors prefer gastroscopy so much? Generally speaking, doctors will recommend gastroscopy for people with ulcer disease, gastric bleeding and high risk of gastric cancer. Most people who suffer from stomach pain and stomach bleeding will accept gastroscopy, but gastroscopy is not so cool for people who are at high risk of stomach cancer for early examination or health checkups, so let’s briefly explain why doctors will recommend gastroscopy for these people. The great thing about gastroscopy is that it reaches into the stomach with the help of a thin, soft tube, and through the mirror-like probe at the bottom, it can look straight into the inside of the stomach and see the changes inside the stomach clearly. Although many people will find it uncomfortable, with the development of endoscopic technology and the increase in humanistic care and emphasis on patient experience, gastroscopy is no longer as “simple and brutal” as it was once thought to be. For those who have particularly sensitive gag reflex or fear, they can choose to undergo gastroscopy under anesthesia, so that the gastroscopy will be over as soon as they wake up and avoid the psychological fear. Compared with Korea and Japan, the rate of early gastric cancer is very low, and most of the patients are already in advanced stage when they are found; while Korea and Japan are also countries with high incidence of gastric cancer, but their early detection rate is very high, which makes the cure rate much higher, mainly because of the popularity of gastroscopy in Korea and Japan. Therefore, it is necessary to promote gastroscopy for early detection and early treatment. Generally, doctors will recommend gastroscopy to those who are at high risk of stomach cancer, who are at high risk of stomach cancer and need gastroscopy more than the general population? 1. People with family history of tumor. In two or three generations of relatives who have had digestive system tumors or other tumors, their chances of getting stomach cancer will be higher. The response is to do professional tumor screening about 10 years earlier than the youngest age of cancer members in the family, and gastroscopy should be done for gastric cancer, every 3 years, according to the doctor’s recommendation. For example, if the minimum age of cancer members in the family is 55 years old, then the first gastroscopy should be done at the age of 40. 2.People with bad habits such as long-term smoking, drinking alcohol, and especially love to eat hot food, pickled and barbecued food, and high-salt food. These habits can cause more serious damage to the stomach and should be adjusted in a timely manner, and pay attention to gastroscopy 3, people with long-term chronic gastric diseases such as gastric ulcer, chronic atrophic gastritis and chronic gastritis. People with these diseases should be treated actively to prevent disease progression and go to hospital for regular review. The early manifestation of gastric cancer is very secretive, which may be the same as a small plaque growing on our hand, only the color of gastric mucosa has changed a little. The current technology such as CT and contrast can only scan a certain diameter of gastric lesion, but cannot capture such a small change, so there is almost no way to detect early gastric cancer by CT, therefore, those who should have gastroscopy should not hesitate. As the incidence of tumor is getting higher and higher and the quality of food is worrying, it is recommended to strengthen the awareness of self-prevention of tumor, and besides avoiding exposure to toxic and harmful substances and environment, early detection and early diagnosis and treatment are also very important links. General population health checkup: It is recommended that people over 45 years old should have at least one gastroscopy, and those who have no positive findings generally do not need to have one within 3 years; those who have gastroscopy and found to have chronic atrophic gastritis with risk factors such as intestinal epithelial hyperplasia or heterogeneous hyperplasia should have annual follow-up to detect the problem early. Although some people may find gastroscopy unpleasant, it should still need to be accepted compared to the regret brought about by avoidance. With the development of technology and the popularization of the concept, it is a trend for gastroscopy to become a routine medical examination. Of course, we should also consider the reasons why people are reluctant to accept it (uncomfortable and avoidance), and provide them with the right guidance to eliminate the psychological fear or burden. First, we should change our mindset before we can popularize gastroscopy like other health checkups.
