Endoscopy Q&A

What is endoscopy?

Endoscopy refers to various procedures that use special tools that allow health care providers to evaluate your internal organs without the need for large surgical incisions. 

During an endoscopy, providers use an endoscope, which is a thin flexible tube with a tiny surgical camera and light. This camera transmits live-action images of your internal body parts onto a computer monitor for evaluation and treatment. 

The expert team at Northern Virginia Gastroenterology, P.C., performs endoscopy procedures to look at your digestive system.

What are the types of endoscopy?

Northern Virginia Gastroenterology, P.C., provides many types of endoscopy procedures. These types include:

Upper endoscopy

During an upper endoscopy, your gastroenterologist at Northern Virginia Gastroenterology, P.C., uses an endoscope to look at the lining of your esophagus, stomach, and the upper portion of your small intestine — the duodenum.

This procedure is also known as an esophagogastroduodenoscopy (EGD).


For a colonoscopy, the team evaluates the lining of the large intestine. This is one of the gold standard tests for colon cancer screening.

Capsule endoscopy

A capsule endoscopy involves swallowing a pill-sized camera that takes thousands of pictures as it travels through your digestive tract. The capsule endoscopy allows the team at Northern Virginia Gastroenterology, P.C., to see parts of your digestive tract not accessible with an upper endoscopy or colonoscopy.

Though there are many types of endoscopic procedures, in most cases, an endoscopy refers to an EGD, or upper endoscopy.

Why would I need an upper endoscopy?

Your gastroenterologist or primary care provider explains in detail why you need an upper endoscopy. They may recommend this diagnostic procedure to determine the underlying cause of your anemia, abdominal pain, nausea, or unexplained weight loss.

The upper endoscopy may help diagnose digestive conditions such as:

  • Gastroesophageal reflux disease (GERD)
  • Esophagitis or gastritis
  • Esophageal strictures — narrowing of the esophagus
  • Barrett’s esophagus — change in tissue type in the esophagus
  • Benign and cancerous tumors
  • Stomach ulcers
  • Crohn’s disease
  • Celiac disease

The team may also recommend an upper endoscopy to treat esophageal strictures, stop upper GI bleeding, or remove polyps. 

What are the preparation steps for an endoscopy?

The Northern Virginia Gastroenterology, P.C., team provides specific instructions on the steps you need to take to prepare for your endoscopy. 

It’s important to follow these bowel prep instructions as directed to remove all debris from your digestive tract to ensure you get a thorough evaluation.
