Board-certified, Brown-trained gastroenterologist with 25+ years of practice. Dr. Kevin S. Palumbo pairs advanced GI and liver care with functional, whole-body medicine as Medical Director of GetFitRx.
Trillions of microbes, about 70% of your immune tissue and a nervous system of its own. Tap each system to see how it connects back to the gut.
Gut hormones such as GLP-1 and PYY tell your brain you are full. Your microbes also influence how many calories you extract from food.
Modern medicine is powerful, but lasting gut health rarely comes from a prescription alone. Dr. Palumbo pairs specialist GI care with root-cause testing, food knowledge, and the coaching and accountability that turn a plan into results.
Alongside standard GI evaluation such as labs and endoscopy, comprehensive stool analysis (GI mapping) can look at the microbiome, digestion, inflammation markers and hidden infections. The goal is to treat the cause, not just the symptom.
What you eat shapes your microbiome within days. Dr. Palumbo wants patients to understand why food matters so changes stick: more fiber and protein, fewer ultra-processed foods, and meals matched to their gut.
When it's needed, he uses today's best tools: newer acid blockers for reflux, targeted IBS treatment, and GLP-1 and other peptide-based medicines for diabetes and weight loss.
Knowing what to do is half the work. Weekly check-ins, nutrition coaching and strength training turn a plan into lasting results. That's where GetFitRx comes in.
How GetFitRx helps →GLP-1 medicines, which are peptide-based, have changed how type 2 diabetes and obesity are treated. As a gastroenterologist, Dr. Palumbo understands both their benefits and their GI side effects, such as nausea and constipation, and how to manage them. He also knows what makes results last.
I can find the root cause and prescribe the right medicine. What I don't have is time to check in on every patient's diet each week or teach a 30-minute strength class. GetFitRx does exactly that, with professionals second to none. It's the perfect marriage for my patients, and it's why I was eager to serve as Medical Director.Kevin S.
