EGD Test: What You Need to Know

An EGD test, also known as an upper endoscopy or upper GI endoscopy, is a diagnostic procedure used to examine the upper digestive tract. This article will explain what an EGD test entails, the reasons it may be performed, and how to prepare for one.

What is an EGD Test?

An EGD test (or esophagogastroduodenoscopy) is a procedure that allows doctors to view the lining of the esophagus, stomach, and duodenum—the first part of the small intestine.

It is a form of gastrointestinal endoscopy that uses a flexible tube equipped with a light and camera, known as an endoscope. The test helps to identify problems in the upper digestive tract, such as inflammation, ulcers, tumors, or bleeding.

For more detailed evaluations, an endoscopic ultrasound may be performed in conjunction with the EGD to get clearer images of the surrounding structures.

What Happens During an EGD Test?

An EGD test involves inserting a flexible tube through the mouth and into the upper digestive tract. The endoscope transmits images to a monitor, allowing doctors to inspect the inner lining of the esophagus, stomach, and duodenum for any abnormalities.

In some cases, small tissue samples (biopsies) may be taken for further testing, or certain treatments, like stopping bleeding, may be performed during the procedure.

Why Are EGD Tests Performed?

EGD tests are often recommended to diagnose or monitor a variety of digestive system problems, such as:

  • Persistent stomach pain or heartburn
  • Trouble swallowing
  • Unexplained weight loss or anemia
  • Bleeding in the upper digestive tract
  • Nausea or vomiting
  • Abnormal results from other tests, such as X-rays or CT scans
  • Suspected digestive and kidney diseases that affect the upper digestive system

How to Prepare to Take an EGD Test

To ensure accurate results, it’s important to prepare properly for an EGD test:

  1. Fasting: Avoid eating or drinking for at least six to eight hours before the test to keep the stomach empty.
  2. Medication Adjustments: Your doctor may advise you to stop taking certain medications, such as blood thinners, that could increase the risk of bleeding during the procedure.
  3. Arrange for a Ride: Since conscious sedation is commonly used during the test, it’s important to have someone available to drive you home afterward.

What Can I Expect During an EGD Test?

During the EGD test, you will be given a local anesthetic to numb the throat and a sedative to help you relax. Here’s how the procedure typically unfolds:

  1. Preparation: You will lie on your side, and the doctor will spray a local anesthetic on your throat. Conscious sedation, administered intravenously, will help you remain calm and comfortable throughout the procedure.
  2. Insertion of the Endoscope: The flexible tube is gently inserted into your mouth and guided down the throat. As it moves into the esophagus, stomach, and duodenum, the camera on the endoscope transmits live images to a monitor.
  3. Examination: The doctor will look for signs of inflammation, ulcers, growths, or bleeding. If needed, small tools passed through the endoscope can take biopsies or perform certain treatments. An endoscopic ultrasound might be used to obtain more detailed images, especially if a suspicious area is found.
  4. Completion: The procedure typically takes about 15-30 minutes. Afterward, the endoscope is carefully removed, and you’ll be taken to a recovery area.

Risks and Complications

While EGD tests are generally safe, they do carry a small risk of complications. These can include:

  • Sore throat: It’s common to experience mild throat discomfort for a day or two following the procedure.
  • Bleeding: There may be a slight risk of bleeding, particularly if a biopsy was taken or a treatment was performed.
  • Infection: Though rare, an infection could develop at the biopsy site.
  • Reaction to Sedation: Some individuals may experience side effects from conscious sedation, such as dizziness or nausea.

 

Understanding EGD Test Results

After the procedure, your doctor will review the findings with you. The results may show:

  • Normal findings: No abnormalities detected in the esophagus, stomach, or small intestine.
  • Signs of inflammation, ulcers, or tumors: These may require further testing or treatment.
  • Biopsy results: If a tissue sample was taken, the results could indicate the presence of certain conditions, such as infections, celiac disease, or cancer.
 

Understanding upper endoscopy results is crucial for determining the next steps in managing any detected conditions.

What to Expect After an EGD Test

Recovery from an EGD test is usually quick, but here’s what you can expect:

  1. Rest and Observation: After the test, you’ll rest for a short period while the effects of the sedation wear off. Your blood pressure and other vital signs will be monitored during this time.
  2. Temporary Sore Throat: A sore throat is common and can be relieved with throat lozenges or warm saltwater gargles.
  3. Activity Restrictions: Avoid driving, operating heavy machinery, or making important decisions for the remainder of the day due to the lingering effects of sedation.
 

If you experience any unusual symptoms, such as a digestive system problem, severe pain, vomiting, or fever, contact your doctor promptly.
