Endoscopy

Upper endoscopy, also known as esophagogastroduodenoscopy (EGD), is a minimally invasive procedure used to examine the upper digestive tract, including the esophagus, stomach, and the beginning of the small intestine (duodenum). During an upper endoscopy, a thin, flexible tube called an endoscope is inserted through the mouth and gently guided down the throat into the digestive tract. The endoscope has a light and a camera on its tip, allowing the doctor to visualize the lining of the digestive organs and identify any abnormalities.

Upper endoscopy is performed for various reasons, including investigation and diagnosis of digestive symptoms such as persistent heartburn, difficulty swallowing, unexplained weight loss, or abdominal pain. It is also used to evaluate and monitor conditions such as ulcers, inflammation (such as gastritis or esophagitis), polyps, or tumors. Additionally, during the procedure, the doctor can collect tissue samples (biopsies) for further examination or perform therapeutic interventions, such as removing polyps or treating bleeding.

Upper endoscopy is typically performed as an outpatient procedure, and patients are usually given sedation to help them relax and minimize discomfort. Before the procedure, patients will be asked to refrain from eating or drinking for a specified period to ensure the stomach is empty. After the procedure, patients may experience a mild sore throat or bloating, which usually resolves quickly. It is important to follow the doctor's instructions regarding diet and medication after the procedure. Results and further recommendations will be discussed during a follow-up appointment with the doctor, based on the findings of the upper endoscopy.
