Frequently Asked Questions (FAQs)
1. What is a Gastroenterologist?
A gastroenterologist is a medical doctor who specializes in the diagnosis, treatment, and prevention of diseases related to the digestive system. This includes the esophagus, stomach, small and large intestines (colon), liver, gallbladder, and pancreas.
2. When should I get a screening colonoscopy?
For individuals at average risk, it is recommended to have your first screening colonoscopy at age 45. This procedure is the most effective tool we have for preventing colorectal cancer. If you have a family history of colon cancer or other risk factors, you may need to be screened earlier.
3. What is the difference between Crohn's Disease and Ulcerative Colitis?
Both are types of Inflammatory Bowel Disease (IBD), but they affect different parts of the digestive tract. Ulcerative Colitis is limited to the large intestine (the colon). Crohn's Disease can affect any part of the digestive tract.
4. What is GERD, and why is it important to treat it?
GERD (Gastroesophageal Reflux Disease) is a condition where stomach acid frequently flows back into the esophagus, causing symptoms like heartburn. While common, it's important to manage GERD because chronic acid exposure can damage the esophagus and lead to more serious conditions, such as Barrett's Esophagus, which is a risk factor for esophageal cancer.
5. What is an upper endoscopy or EGD?
An EGD (esophagogastroduodenoscopy) is a procedure where I use a thin, flexible tube with a camera to examine the upper part of your digestive system. It is commonly used to investigate symptoms like persistent heartburn, difficulty swallowing, abdominal pain, or bleeding.
