Gastroscopy is one of the important examination methods of upper digestive tract diseases, which is of great significance for finding digestive tract inflammation, ulcer, benign and malignant tumors, etc. Gastroscopy mainly sends the "lens" of the gastroscope into the gastrointestinal tract through the oral cavity or nasal cavity, and visually observes the internal surface mucosa of the gastrointestinal tract for examination. At the same time, the gastroscope can easily take pathological biopsy, and some can even perform local treatment (lesion resection). However, after all, gastroscopy is an invasive examination, and many people think that gastroscopy is very painful, so there is more or less discomfort in the examination process, and some psychological factors are added. Therefore, some people also talk about the color change of gastroscopy, and they hesitate or even resist before doing gastroscopy. So, how much harm does a gastroscope do to the human body?
As we know, currently commonly used gastroscopy is divided into painless gastroscopy and common gastroscopy. The difference between them is mainly whether anesthetics are used during the operation. Ordinary gastroscope does not need anesthesia, its operation and preparation before operation are relatively simple, with little risk, and there is no risk of anesthesia accident, and it is applicable to a wider range of people. Generally, some people will feel uncomfortable or painful in their throat more or less during the process of "lens" entry. In some cases, severe cases may cause severe nausea and vomiting due to stimulation of local mucosa, which will affect the observation of the operating doctor, and severe cases may lead to interruption of examination.
Painless gastroscope will not cause discomfort, nausea and vomiting and other violent reactions in the examination process, and the probability of injury is small, which is beneficial for the operating doctor to observe the pathological changes under the microscope. However, due to the need of anesthesia, it needs to be prepared before the operation and accompanied by family members, so there are anesthesia risks and anesthesia accidents, including allergies, dyspnea, blood pressure and blood oxygen fluctuations, and so on. After the operation, discomfort such as dizziness may occur, which can only be relieved when the anesthetic is completely metabolized.
