14 Oct 4 Types of Digestive Health Screenings
Digestive issues can range from occasional discomfort to serious conditions that affect overall health. A gastroenterologist specializes in diagnosing and treating disorders of the digestive system, often using targeted screenings to detect problems early. Understanding the different types of digestive health screenings helps patients know what to expect and why these tests matter. Here are four digestive health screenings GI doctors use:
1. Colonoscopy
A colonoscopy is a procedure used to examine the large intestine and rectum. Your GI doctor will insert a thin, flexible tube with a camera, called a colonoscope, into the rectum. This allows the gastroenterologist to view the entire colon and detect abnormalities such as polyps, inflammation, or signs of cancer.
A colonoscopy is helpful for investigating symptoms like rectal bleeding, chronic constipation or diarrhea, and abdominal pain. It is also a fundamental screening tool for colorectal cancer, and doctors generally recommend it for adults starting at age 45. A clear liquid diet and a special bowel preparation are required the day before the procedure to make sure the colon is clean.
2. Upper Endoscopy (EGD)
An upper endoscopy, or esophagogastroduodenoscopy (EGD), is a procedure used to examine the upper part of your digestive system. This includes the esophagus, stomach, and the first part of the small intestine (duodenum). A gastroenterologist uses a long, flexible tube with a camera, called an endoscope, which is passed through the mouth and down the throat. This screening is helpful for diagnosing conditions like acid reflux, ulcers, and celiac disease. Your GI doctor may recommend an EGD if you have symptoms such as difficulty swallowing, persistent heartburn, nausea, or upper abdominal pain.
3. Abdominal Ultrasound and Imaging Tests
Abdominal ultrasounds and other imaging tests are non-invasive methods used to visualize the organs within the abdomen. An ultrasound uses sound waves to create images of organs, such as the liver, gallbladder, pancreas, and kidneys. Other imaging tests, such as CT scans or MRIs, provide detailed cross-sectional images of the abdominal structures.
These tests are helpful in identifying issues such as gallstones, liver disease, and pancreatic abnormalities. A gastroenterologist may order these tests to investigate the cause of abdominal pain or to evaluate the size and condition of internal organs. Depending on the specific test, you may need to fast for a few hours beforehand.
4. Stool and Breath Tests
Stool and breath tests are non-invasive diagnostic tools that provide helpful information about your digestive function. Stool tests analyze a sample of your feces to detect the presence of blood, bacteria, parasites, or markers of inflammation. Breath tests are used to diagnose issues such as small intestinal bacterial overgrowth (SIBO) or lactose intolerance. For a breath test, you will drink a specific sugar solution and then breathe into a collection device at timed intervals. The test measures the levels of certain gases, such as hydrogen and methane, in your breath to help identify digestive problems.
