What to Expect
What to Expect During an Upper Endoscopy
During the Procedure
- The procedure may generally take between 15-30 minutes.
- Your breathing, blood pressure and heart rate will be monitored.
- You typically receive sedatives to keep your relaxed.
- Your doctor may spray anesthetic in your mouth.
- The endoscope is then inserted in your mouth and passed through your esophagus and into your stomach and small intestine. The endoscope does not interfere with your breathing.
- A tiny camera at the tip of the endoscope will transmit images to a video monitor to look for abnormalities.
- Your doctor will pass special surgical tools through the endoscope to collect tissue samples or remove a polyp if indicated.
- The endoscope will then slowly be retracted through your mouth.
After the Upper Endoscopy
When the procedure is completed, you’ll go to a recovery area so your healthcare team can monitor you as the sedative wears off. Some mild symptoms that typically wear of within a few hours may include mild bloating or cramping or a sore throat.
These signs and symptoms will improve with time and you should take it easy for the rest of the day. If you’re concerned or uncomfortable, call your doctor.
Your Doctor will give you specific guidance for follow-up after the procedure.
