• Anoscopy: As part of your routine healthcare, an anoscopy offers a direct visual assessment of your anal canal and rectum, facilitating the early detection and management of any concerning changes.
• Colonoscopy: Taking charge of your gut health starts with a colonoscopy: it's a vital screening test that detects abnormalities in your large intestine early, often before symptoms appear.
• Duodenal Polypectomy: Protecting your digestive system's health, duodenal polypectomy is a procedure that removes polyps from your duodenum, enabling early detection of abnormalities and helping prevent future problems.
• Endoscopy: Protecting your digestive health starts with an endoscopy, which provides detailed images of your entire digestive tract, enabling early detection and treatment of a wide range of issues.

Here are answers to some common questions about proactive Gastrointestinal care with Dr. Marissa Bournique:

What is a Gastroenterologist?

Dr. Bournique and our team are gastroenterologists, meaning we are specialists trained to care for the health of your digestive system, including the esophagus, stomach, intestines, colon, liver, gallbladder, and pancreas. We diagnose and treat conditions, and perform preventive screenings like colonoscopies.

When should I get my first screening colonoscopy?

For average-risk individuals, routine screening colonoscopies are now recommended to begin at age 45. However, those with a family history of colon cancer or other risk factors may need to start earlier. Dr. Bournique will determine the best, personalized screening schedule for you.

Is the preparation for a colonoscopy difficult?

Many patients have concerns about colonoscopy prep, but modern solutions are much easier to tolerate than before. A clean colon is crucial for a thorough examination and to identify and remove any polyps. This one-day preparation is a small price to pay for years of peace of mind.

What is a capsule endoscopy?

Capsule endoscopy is a modern, non-invasive way to examine the small intestine, a difficult area to reach with traditional scopes. A small, pill-sized camera is swallowed, taking thousands of pictures as it travels through the digestive tract. This allows Dr. Bournique to identify potential issues, such as ulcers or tumors.

How do you manage chronic conditions like Crohn's disease or ulcerative colitis?

We partner with patients to achieve and maintain remission of chronic conditions like Crohn's and ulcerative colitis. This involves advanced therapies to control inflammation, personalized nutritional guidance, and regular monitoring to prevent flare-ups and improve quality of life.

What are some common signs of liver problems I should watch for?

Some common signs of liver problems include jaundice (yellowing of the skin or eyes), persistent fatigue, abdominal swelling, and unexplained dark urine. If you experience any of these symptoms, please schedule a consultation with Dr. Marissa Bournique for a thorough evaluation.

What are gallstones?

Gallstones are small, hard deposits that can form in the gallbladder. Many people have gallstones without any problems. They only become a concern if they cause blockages, leading to pain, and Dr. Bournique can help diagnose this issue.

What is 'fatty liver disease' and is it serious?

Non-alcoholic fatty liver disease (NAFLD) is a very common condition often linked to metabolic health issues like obesity and diabetes. Fortunately, in its early stages, it can often be reversed with lifestyle changes. However, it's important to manage NAFLD to prevent progression to more serious liver damage, such as cirrhosis.
