How Do I Prepare for a Gastroenterology Test?

How Do I Prepare for a Gastroenterology Test?

Preparation for a gastroenterology test depends on the type of test. Some tests require no preparation, while others require 24 hours or more. 

Many people are familiar with colonoscopies since they are used for cancer screenings as well as diagnosis. Preparation for this test requires drinking a solution that cleanses your colon. This process can take up to 24 hours. Your GI doctor will often ask you to fast before a procedure, such as an endoscopy or some scans. Fasting allows food to move out of the upper digestive system so it does not obstruct scanners. 

Some scans may require a solution you drink or have injected. These solutions let the scanners see your digestive systems more clearly. Your gastrointestinal specialist will explain the purpose of each scan and what you can expect. 

What Conditions are Diagnosed With a Gastroenterology Test?

If you see a doctor about problems with your digestive system, you will often be referred to a gastroenterologist. These GI doctors will usually order tests ranging from blood tests to endoscopies to diagnose your condition and plan your treatment. Conditions diagnosed this way include:

• • Cancers of the digestive system
  • Polyps
  • Diverticulitis
  • Ulcers
  • Crohn’s disease
  • Celiac disease
  • Irritable Bowel Syndrome
  • Gastroesophageal Reflux Disease
  • Ulcerative colitis

In some cases, one blood test or scan will allow your gastroenterologist to diagnose your condition. In other cases, especially complex or chronic conditions, you may need several types of tests to help your doctor develop a treatment plan.
