All You Need to Know About Endoscopy Gastro

During a regular gastroendoscopy, the doctor usually holds the end of the gastroscope with his right hand and slowly inserts it into the mouth towards the base of the tongue. At this point, there is often a feeling of nausea. When the nausea is obvious or when the patient swallows, the upper esophageal sphincter opens, and the doctor will insert the gastroscope into the esophagus through the opening. When the patient's cooperation is poor, the doctor often reminds them to swallow, as this will facilitate the insertion of the gastroscope.
