FAQ's Related to Gastroenterologist

It is a Gastroenterologist who helps you get treated for the health conditions you suffer from related to the digestive system. 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

Please do have a look at the various tests required prior to and during the consultation with a Gastroenterologist.:

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

The condition which is affecting the patient can be understood through procedures such as Colonoscopies, Gastroscopies and Liver biopsies. An Endoscopy uses a camera inserted inside body via mouth through to esophagus with a thin and long tube to send back images which can help decipher symptoms. The difference between an endoscopy and a Colonoscopy, Sigmoidoscopy is that in these two the tube is inserted via rectum. 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.

Symptoms indicating a clear digestive system or tract related condition or being in an age bracket above fifty mean that you must go to see a Gastroenterologist. Sometimes the condition is clear and not just an indicative symptom, few conditions that would need a visit are suspected gallstones, ulcers, and Hemorrhoids. Regular consultations with the doctor make it simpler for you to attain excellent digestive health post a surgery.
