Elite Medical Services

Third Eye® Colonoscopy

Catch pre-cancerous polyps early with the Third Eye® Colonoscopy – a revolutionary advancement in colonoscopy technology that allows for a more complete examination by deploying both forward and rear-view cameras. Clinical trials show that the Third Eye colonoscopy resulted in a 40% increase in pre-cancerous polyp detection in high-risk patients.


With the PillCam capsule endoscopy, detecting GI disorders is as simple as swallowing a pill. This non-invasive procedure helps diagnose disorders of the small intestine. The patient simply swallows a small pill fitted with a camera, which transmits images to a device as it moves through the small intestine throughout the day.

Breath Tests

A simple breath test can effectively diagnose the causes of symptoms such as gas, bloating, diarrhea, and abdominal pain. At the Center for GI Health, we perform several different breath tests including:

  • Lactulose breath test to diagnose small intestinal bacterial overgrowth (SIBO)
  • Lactose intolerance
  • Fructose intolerance
  • H. pylori breath testing
