Upper GI Endoscopy
If you are having unexplained nausea, painful swallowing, heartburn, or other symptoms affecting your gastrointestinal (GI) tract, your healthcare provider may want to perform a procedure called an upper endoscopy. This procedure allows a healthcare provider to see inside of your esophagus, stomach, and small intestine by inserting an endoscope (a bendable tube that acts like a video camera) into your throat. An upper endoscopy is also known as an esophagogastroduodenoscopy, or EGD for short.
This GI procedure takes 20 to 30 minutes to complete. Because you will be sedated, you will need to rest at the facility for one to two hours until the medication wears off.
