• Duodenal Polypectomy: Duodenal polypectomy is a procedure to remove polyps from your duodenum, a part of your small intestine, helping prevent potential complications and enabling early detection of cancerous or precancerous growths.

Here are answers to some common questions about proactive Gastrointestinal care with Dr. Jonathan Keshishian:

What is a Gastroenterologist?

A gastroenterologist is a specialist doctor who is highly trained in the health of your digestive system, including the esophagus, stomach, intestines, colon, liver, gallbladder, and pancreas. They are experts in diagnosing and treating digestive conditions, and also 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. Keshishian will determine the best, personalized screening schedule for you.

What are colon polyps, and are they dangerous?

Colon polyps are small, non-cancerous growths in the colon. While some types can potentially develop into cancer over time, a colonoscopy allows us to find and remove these polyps before they have a chance to become cancerous, preventing the disease.

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

We work in a long-term partnership to achieve and maintain remission. Advanced therapies help control inflammation, and nutritional guidance, combined with regular monitoring, prevent flare-ups and improve your quality of life.

What is the difference between Inflammatory Bowel Disease (IBD) and Irritable Bowel Syndrome (IBS)?

Inflammatory Bowel Disease (IBD), including Crohn's disease and ulcerative colitis, is an autoimmune condition causing inflammation and damage to the gastrointestinal tract. Irritable Bowel Syndrome (IBS), in contrast, is a functional disorder characterized by symptoms like cramping and bloating, but without the same physical inflammation or damage.

I have frequent heartburn. When should I be concerned?

While occasional heartburn is common, frequent or worsening symptoms (more than twice a week) may indicate a condition like GERD. This warrants a consultation with Dr. Keshishian to diagnose the cause and create a personalized treatment plan. Untreated GERD can lead to more serious complications.

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 like cirrhosis.

Is the preparation for a colonoscopy difficult?

Many patients worry about colonoscopy prep, but modern solutions are much easier to tolerate than in the past. A clean colon is essential for a thorough exam, and this one-day prep is a small price to pay for years of peace of mind.
