Can gastroscope check esophageal reflux?

Gastroesophageal reflux disease (GERD) is commonly referred to as gastroesophageal reflux disease (GERD). Gastroscopy

is an endoscope that passes through the mouth, esophagus, and stomach to examine the internal conditions of the esophagus, stomach, duodenum, etc. If the patient has GERD, gastroscopy often directly observes redness, ulceration, stricture, etc. of the esophageal mucosa. At the same time, gastroscopy can also help evaluate the function of the lower esophageal sphincter and determine whether there is GERD. In addition, part of the diseased tissue can be removed for pathological examination during gastroscopy, which can help rule out other possible diseases.
