What is an Upper Endoscopy?
An upper endoscopy allows your provider to examine your esophagus, stomach, and the first part of the small intestine.
It’s commonly used to help find the cause of symptoms such as:
- Heartburn
- Trouble swallowing (dysphagia)
- Stomach pain or nausea
- Abnormal test results
In some cases, your provider may be able to treat problems during the procedure.
What to Expect During an Upper Endoscopy
- Medication is given to help you relax and stay comfortable
- A thin, flexible tube with a camera is gently guided through your mouth
- The procedure typically takes about 15–30 minutes
How to Prepare for an Upper Endoscopy
Your stomach must be empty for the procedure. Your care team will provide specific instructions, including:
- When to stop eating and drinking
- Medication guidance
- Arranging a ride home
What to Expect During an Upper Endoscopy
You’ll rest briefly in a recovery area while the medication wears off. Most people go home the same day. Your provider will discuss initial findings with you, and any tissue sample (biopsy) results will be shared once they’re available.
