Whether it’s bloating, gas, irregular bowel movements, or heartburn—many people live with digestive symptoms for far too long before seeking help. But the truth is, a gastroenterologist can help with far more than people realize.
Brian Katz, MD, is a board-certified gastroenterologist with more than 15 years of experience caring for patients in Central New Jersey. As part of Summit Health’s award-winning Gastroenterology team, he helps patients manage everything from occasional discomfort to complex, chronic conditions. We asked Dr. Katz to walk us through some of the most common questions people have about GI care—and how seeing a specialist can make all the difference.
1. When should I see a gastroenterologist?
Dr. Katz’s advice: If you're experiencing symptoms like bloating, gas, irregular bowel movements, or heartburn on a regular basis, it's worth seeing a GI specialist. These symptoms are common—but they’re not something you need to live with. Even mild issues can be signs of something deeper and are often treatable with personalized care.
2. What if I’ve had reflux or heartburn for years?
Dr. Katz’s advice: You’re not alone. Many people rely on antacids for relief, but that’s not always a long-term solution. Chronic reflux can be related to abdominal pressure, weight around the midsection, or even constipation. A gastroenterologist can help uncover the root cause and recommend lifestyle changes or treatment options that reduce the need for daily medications.
3. Can a GI help me with nutrition or digestive triggers?
Dr. Katz’s advice: Absolutely. Digestive health and nutrition go hand in hand. A GI specialist can help you identify food sensitivities, understand the role of inflammation and build a more gut-friendly routine. Often, simple swaps or small adjustments lead to meaningful changes in how patients feel—more energy, fewer cravings and better digestion.
4. What support is available for chronic GI conditions like Crohn’s, ulcerative colitis, or IBS?
Dr. Katz’s advice: Today’s treatment options for chronic GI conditions are more advanced than ever. Whether you’ve just been diagnosed or have been managing symptoms for years, a GI can help you find a plan that works. With new medications and personalized monitoring, many patients experience fewer flare-ups and a much better quality of life.
In fact, one of my patients came to the office severely underweight, exhausted and struggling to function. Her family believed she simply had irritable bowel symptoms, but further testing revealed Crohn’s disease. With proper diagnosis and the right treatment plan, she began gaining weight, sleeping better and eventually returned to school—thriving in a way her family hadn’t thought possible. Now, she only needs to come in once a year for routine care.
Stories like hers are a powerful reminder: chronic conditions don’t have to define your life—and the right care can change everything.
5. When should I get a colonoscopy—and what should I expect?
Dr. Katz’s advice: Colon cancer screening now starts at age 45 for most adults and even earlier if you have a family history. The procedure itself is quick and effective—often preventing cancer by catching polyps early. A GI team like Summit Health’s can guide you through every step.
6. How do endoscopies and colonoscopies help with diagnosis?
Dr. Katz’s advice: These procedures allow GI doctors to get a clear view of your digestive tract and identify things like inflammation, ulcers, or abnormal growths. They're essential tools when other tests aren’t providing answers. At Summit Health, convenience is a priority—we aim to reduce stress and make the experience as smooth as possible for patients.
7. I have symptoms I’m embarrassed to talk about. Should I still see a GI?
Dr. Katz’s advice: Yes—especially then. Many people silently deal with symptoms like gas, urgent bowel movements, or even fecal incontinence because they’re too embarrassed to speak up. But these symptoms are more common than most realize—and they are treatable. A gastroenterologist can offer respectful, effective care that helps patients regain confidence and comfort.
8. What if I’m not even sure what’s wrong—but I just don’t feel like myself?
Dr. Katz’s advice: That’s exactly when you should consider reaching out. You don’t need a clear diagnosis to benefit from GI care. Many patients come in with vague symptoms—fatigue, discomfort after eating, disrupted sleep—and discover treatable causes. The goal of GI care isn’t just to manage disease, but to help you feel better every day.
