Whether or not you should have a gastroscopy to check your stomach depends on your condition. In addition to gastroscopy, stomach examination can also be examined by other means, such as barium meal, etc., but gastroscopy is undoubtedly the most important method to examine the stomach. The main ways to check the stomach are: 1, through gastric fluid analysis to diagnose gastric disease, the first extraction of gastric fluid for the determination of relevant indicators, such as gastric acid, etc., from which you can determine whether the amount and concentration of gastric fluid secretion is within the normal range. 2.The presence of ulcers, tumors, diverticula and obstruction can be checked by barium x-ray imaging. It mainly shows the outline of the stomach by taking barium orally. The recognition rate of small lesions such as inflammation and early cancer is low. 3.Gastroscopy can examine lesions in the stomach and duodenum, and even micro lesions can be identified. Endoscopy technology has advanced greatly this year, and it can be used to do in-depth identification of lesions through magnification, staining and electronic staining, and home ultrasound technology. Patients with epigastric pain, epigastric masses, vomiting blood and a history of atrophic gastritis will need a gastroscopy to clarify the diagnosis. So it is not always necessary to do gastroscopy for stomach examination, it needs to be decided according to the specific condition, and the choice of which examination is best left to a professional doctor.
