Westside Gastroenterology

When would I need to see a gastroenterologist?

Gastroenterologists are trained to treat diseases and conditions affecting the gastrointestinal (GI) tract, including issues affecting the esophagus, stomach, duodenum, gallbladder, liver, pancreas, small intestine, colon (large intestine) and rectum. If you experience symptoms with any of these organs, you should request a GI consultation appointment. Symptoms could include:

  • abdominal pain

  • chronic diarrhea

  • chronic constipation

  • rectal bleeding or bloody stools

  • painful bloating

  • difficulty swallowing

  • chronic heartburn

What happens during a gastroenterology consultation?

A consultation appointment begins with a medical history that includes your personal medical history and the histories of close family members to look for possible risk factors for diseases. You'll also be asked to describe your symptoms and when they first occurred. A physical exam will be performed which may include gentle palpation of your belly to check for areas of distension or tenderness. Once the exam is complete, diagnostic tests like colonoscopy or endoscopy may be ordered, and additional lab work like blood tests or stool samples may also be requested. In some cases, diagnostic imaging tests including barium x-rays may be requested as well. Based on your exam, treatment recommendations can be made using the most advanced, most effective and safest methods for optimal results based on your individual needs.

How should I prepare for my consultation appointment?

If you've had imaging tests, lab work or other tests performed that relate to your symptoms, you should have those results forwarded to the office prior to your appointment so they can be reviewed with you and help guide diagnosis and treatment. You should also be ready to list any medical issues you or your close family members have experienced, as well as a list of any medications, vitamins or supplements you may be taking. If you have questions, you might want to make a list to ensure all your concerns are addressed.
