Biologics: Explanation of how doctors use biologics to treat digestive disorders.
Endoscopy: A minimally invasive procedure that allows a gastroenterologist to look inside the digestive tract using a thin, long tube with a camera on the end. Endoscopy can help diagnose a range of digestive disorders, including ulcers, inflammatory bowel disease, and cancer.
Colonoscopy: An endoscopic procedure that examines the large intestine (colon) for abnormalities, such as polyps or cancer. A colonoscopy is used to screen for colon cancer and can also help diagnose inflammatory bowel disease or other conditions causing abdominal pain, rectal bleeding or changes in bowel habits.
Biopsy: A procedure where a small amount of tissue is removed from the digestive tract for examination under a microscope. A biopsy can help diagnose and stage certain digestive disorders, such as gastric cancer, celiac disease or H. pylori infection.
Imaging tests: Such as CT scan, MRI, ultrasound or X-ray, use advanced imaging technology to create images of the digestive tract and surrounding organs. These tests can help detect tumors, inflammation and structural abnormalities.
Fecal occult blood test: A test that looks for hidden blood in stool samples that cannot be seen with the naked eye. The presence of blood can indicate digestive disorders, such as cancer, inflammatory bowel disease or diverticulitis.
Esophageal manometry: A test that measures the strength and coordination of the muscles in the esophagus, which is the muscular tube that connects the mouth to the stomach. It can help diagnose disorders of swallowing or gastroesophageal reflux disease (GERD).
pH monitoring: A test that measures the acidity (pH) levels in the esophagus over time to diagnose GERD or other conditions causing acid reflux.
Breath tests: Used to diagnose lactose intolerance, fructose malabsorption or bacterial overgrowth in the intestine, such as SIBO. Breath tests typically require the patient to consume a drink or food that contains a specialized sugar or substrate, and then measure the gases that are produced in the breath.
Blood tests: Used to measure various enzymes, hormones or antibodies in the blood that can indicate the presence of digestive disorders or inflammation. Common examples include liver function tests, C-reactive protein or fecal calprotectin.
It's important to keep in mind that not all of these tests are necessary or appropriate for every patient or particular condition: The choice of diagnostic test will depend on a range of factors, including the patient's symptoms, medical history, lifestyle and risk factors. Only your doctor can determine which tests are appropriate for your particular case.
