Upper Endoscopy is a medical procedure that allows doctors to examine the upper part of the digestive system, including the esophagus, stomach, and duodenum. During the procedure, a thin, flexible tube with a camera, called an endoscope, is inserted through the mouth and guided down the throat. This helps doctors identify issues such as inflammation, ulcers, or tumors. The procedure is typically performed under sedation to ensure patient comfort. It usually takes about 15 to 30 minutes, and patients can often go home the same day. After the procedure, some may experience a sore throat or mild discomfort, but these symptoms usually resolve quickly.
