The upper digestive endoscopy, also known as esophagogastroduodenoscopy (EGD), evaluates the esophagus, stomach, and the first part of the small intestine. It is indicated to investigate symptoms such as persistent heartburn, difficulty swallowing, abdominal pain, nausea, vomiting, or unexplained weight loss — and allows, in the same examination, diagnosis and treatment.
How is an upper digestive endoscopy performed? During the examination, the patient is sedated to ensure comfort. A thin and flexible tube with a camera at the tip, the endoscope, is gently inserted through the mouth and guided through the esophagus to the stomach and duodenum. The camera transmits images to a monitor, allowing the doctor to examine in detail the lining of these organs. If necessary, biopsies can be taken or treatments performed — such as the removal of polyps or the stopping of bleeding — during the same procedure. The examination usually lasts 15 to 30 minutes and patients can return home on the same day.Why is it important? Provides a detailed view of the esophagus, stomach, and duodenum, allowing for the identification of changes that may not be detected by other diagnostic methods. Early detection and intervention help avoid complications and improve overall digestive health, especially in patients with unexplained symptoms or chronic diseases requiring continuous monitoring.
As the examination is performed under sedation, it is recommended that someone accompanies you and does not drive on that day.

No. The examination is performed under sedation, ensuring patient comfort throughout the procedure.
Yes, it is recommended to be accompanied on the day of the examination, as sedation prevents driving on that day.
Endoscopy examines the upper digestive tract (esophagus, stomach, and duodenum). Colonoscopy examines the large intestine (colon and rectum). Your doctor will indicate which, or if both, are necessary.
Whenever you have persistent symptoms such as heartburn, difficulty swallowing, abdominal pain, or unexplained weight loss, or as indicated by your doctor during a gastroenterology consultation.
