Endoscopic examination of the gastrointestinal tract with upper and lower gastrointestinal imaging (using a scope)

What to Expect Before the Procedure

You may be asked to fast for several hours before the procedure, depending on which part of the digestive tract is being examined. Your doctor will explain any specific preparations, such as avoiding certain medications or drinks. You’ll likely receive a mild sedative to help you relax during the procedure.

During the Procedure

The endoscope is gently inserted through your mouth (upper GI) or anus (lower GI) to visualize your esophagus, stomach, or intestines. Images are captured to assess the lining and identify any irregularities. The procedure usually takes 15–60 minutes and is performed in a controlled setting like a hospital or clinic.

Aftercare and Recovery

After the procedure, you may feel mild discomfort, bloating, or a sore throat. You’ll need someone to drive you home, as sedation can impair your ability to drive or operate machinery. Follow your doctor’s instructions for diet, activity, and any prescribed pain relief.

Common Uses and Benefits

This test is used to diagnose conditions like acid reflux, inflammatory bowel disease, bleeding ulcers, or signs of cancer. It provides detailed images that help doctors plan treatments, such as medication adjustments or surgical interventions.
