FAQ's Related to Gastroenterologist

The digestive system is a key part of the body and the conditions or health issues linked to it will get you a referral to a Gastroenterologist. The initial treatment phase with your doctor involves getting your medical history right, ensuring the reports are in order and recommending the required tests. The work of a Gastroenterologist is also to help a patient manage his/her health condition of the digestive tract and digestive system, whether it is via medications and/or diet and other lifestyle changes. 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

The tests required before and during consultation for a Gastroenterologist are as follows:

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

Gastroscopies, Liver biopsies and Sigmoidoscopies are some of the important procedures that help in the better understanding of the gastroenterological conditions. It is easier to understand the symptoms via the images that are sent via the camera attached to the thin, long tube inserted through mouth in Endoscopy and rectum in Colonoscopy, Sigmoidoscopy. 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.

It is important for you to schedule regular visits to the Gastroenterologist if you are in the age bracket of 50 plus years and regular checkups for colorectal cancer are needed or the symptoms which show an imminent condition regards your digestive system or tract.
