An endoscopy lets our specialists directly examine the esophagus, stomach, and the first part of the small intestine — a safe procedure used to detect and prevent conditions like reflux, ulcers, gastritis, and cancer.
What is an endoscopy used for?
Beyond detecting these conditions, an endoscopy helps determine the cause of stomach pain, vomiting, or unexplained weight loss. It can also treat bleeding, remove polyps, take biopsies, and retrieve objects when needed.
How is it performed?
The gastroenterologist uses an endoscope — a thin, flexible tube with a light and camera at the tip. You'll lie on your back as the device passes gently through your mouth, throat, esophagus, stomach, and duodenum.

How should I prepare for my endoscopy?
- Fast for 8 hours before the procedure
- Discuss your current medications with your doctor beforehand
- You may need to make some temporary changes to your diet
What can I expect during the procedure?
The study takes about 10 to 15 minutes. You'll receive sedation, so you will not feel pain. A small amount of air is introduced for better visibility during the exam.
What happens after the procedure?
Your mouth and throat may feel numb for a short time, and mild hoarseness, cough, or bloating are normal. Most people recover fully within 24 hours. If a biopsy was taken, results are typically available within a few days.
