Many people may have this experience: you go to the doctor for an upset stomach. After asking about your condition, the doctor asks you to lie down, presses a few times and says, \"Let's do anOGD<\/a>and have a look.\" Then your common thought is: \"I have to do a gastroscopy. Am I suffering from some serious disease? I heard that a gastroscopy is very painful. Can I not do it?\"<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Gastroscopy can truly reflect lesions that cannot be seen directly with the naked eye, just like looking in a mirror, thus providing a basis for doctors' diagnosis and treatment. The gastroscope is inserted through the mouth and the mucosa of the esophagus, stomach, duodenal bulb and descending part can be clearly observed.<\/div>

Therefore, gastroscopy has incomparable advantages over other examination methods in observing gastrointestinal lesions above the descending part of the duodenum.<\/div>
\u00a0<\/div>
Gastroscopy can not only directly observe lesions, but also take biopsies for pathological examination. It can also perform endoscopic treatment for many diseases, avoiding the trauma and risks brought to patients by traditional laparotomy treatment.<\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
