An upper endoscopy can be used to determine the cause of heartburn and is often performed as an outpatient procedure. Upper endoscopy uses a thin scope with a light and camera at its tip to look inside of the upper digestive system -- the esophagus, stomach, and the first part of the small intestine, called the duodenum. During endoscopy, certain procedures such as taking a small tissue sample (biopsy) for testing may be performed.
Sometimes, the procedure is done in emergencies in the hospital or emergency room to both identify and treat upper digestive system bleeding such as from an ulcer.
You know it all too well. Heartburn. That fiery sensation that grabs hold of your lower chest after you eat something you know you shouldn't have. What often follows is that sour or bitter taste of acid reflux in your throat and mouth that can last minutes (if you are lucky) or hours (if you are not).
Yes, millions of us are familiar with the discomfort of heartburn, a condition in which stomach acids back up into the esophagus. The good news is that heartburn is largely avoidable if you steer clear...
Endoscopy can also help identify inflammation, ulcers, and tumors.
Upper endoscopy can be more accurate than X-rays or other imaging for detecting abnormal growths and for examining the inside of the upper digestive system.
What Should I Do Before an Upper Endoscopy?
Before the upper endoscopy, tell your doctor about any medications (including over-the-counter) or supplements you are taking and about any medical problems or special conditions you have. You may be asked to hold off on certain medications or supplements prior to the procedure or afterward.
Can I Eat or Drink Anything Before an Upper Endoscopy?
An upper endoscopy requires that you have an empty stomach before the procedure. Do not eat or drink anything for at least six hours before the procedure, or as directed by your doctor or nurse.
Talk to your doctor about any changes that may be needed to your regular medication regimen. Ask if necessary medications may be taken with a small sip of water.
I Have Diabetes. Can I Take Insulin the Day of my Upper Endoscopy?
If you have diabetes and use insulin, you must adjust the dosage of insulin the day of your upper endoscopy. Bring your diabetes medication if your doctor recommends that you take it after the procedure.
Will I Be Able to Drive Home Following my Upper Endoscopy?
No. You will need to bring a responsible adult with you to take you home after the endoscopy. You should not drive or operate machinery for the rest of the day of the procedure to ensure that the sedative effects have worn off.
