FAQ's Related to Gastroenterologist

You can be referred to a Gastroenterologist if your symptoms show that the root of your health condition is linked to your digestive system. When you first consult with the doctor, they will ask you the questions and recommend tests that will help gain a better understanding into the illness and its causes. If you need to make lifestyle and dietary adjustments, a Gastroenterologist assists you in keeping up with them and prescribing you the medications. A Gastroenterologist must have the knowledge of various factors such as:

  1. Gastrointestinal organs
  2. Movement of matter via intestines and stomach
  3. Digestion, absorption of nutrients
  4. Removal of body waste
  5. Liver system

Here is a comprehensive list of the tests that are essential prior to and during consultation with a Gastroenterologist.:

  • Gastroscopy
  • Esophageal/Gastric Manometry
  • pH Monitoring
  • Endoscopic Retrograde Cholangiopancreatography (ERCP)
  • Endoscopic Ultrasound
  • Upper GI Series (barium swallow or barium meal)

To understand these conditions better, to have a firm assessment one can undergo procedures such as Liver biopsies, Capsule endoscopies and Colonoscopies. The difference between Endoscopy and Colonoscopy, Sigmoidoscopy is that the tube carrying the camera is inserted via mouth and rectum respectively. This camera sends images which make it easy to understand the symptoms. In an effort to know the causes of your gastroenterological condition, confirm diagnoses and/or monitor treatment response, diagnostic imaging tests like Computed tomography scan (CT or CAT scan), Magnetic resonance imaging (MRI) and Ultrasound play an important role.

Please visit a Gastroenterologist if you are showing symptoms of a digestive system issue or at risk for colorectal cancer because you are more than 50 years of age. You can even visit not just when you have symptoms which show a probable issue with the Gastrointestinal tract but when conditions are clear. Having an excellent digestive health post a surgery and during the rehabilitation process is helped along if you refer to this doctor.
