Most Recommended Gut Health Experts

Hi, I'm Dr. Jeffrey Mark, M.D., a gastroenterologist and functional medicine expert with over 30 years helping people just like you get back to feeling their best. I've dedicated my life to fixing gut health issues, balancing hormones, and tackling heart and energy problems from the root cause—not just masking symptoms with endless meds. My own story started young: At age 10, a bad infection from travel nearly took my life due to a wrong antibiotic, sparking my passion to help others avoid that pain. Later, in my 40s, I battled fatigue, weight gain, high blood pressure, and brain fog from heavy metals and mold toxicity. Using functional and regenerative medicine, I healed myself and now share those tools with you. I earned my B.S. in Neurophysiology from Northwestern University, my M.D. from the University of Illinois College of Medicine, did my internal medicine residency at Northwestern, and specialized in gastroenterology at Chicago Medical School. I'm also certified in medical acupuncture from UCLA and 5X board-certified in functional medicine, anti-aging and regenerative medicine, gastroenterology, obesity medicine, and internal medicine. This lets me blend the best of traditional care with cutting-edge therapies like peptides, PRP, exosomes, and personalized plans. At The Real Gut Doctor, my focus is you: We create custom diets, supplements, and lifestyle tweaks to restore your vitality, mental sharpness, and joy. Whether it's beating IBS, colitis, or low energy, I've guided countless patients to ditch meds, heal after surgery, and live fuller lives. No extreme diets or guesswork—just real results. If you're tired of feeling off and ready for change, let's chat. Visit therealgutdoctor.com or book a discovery call—I'm here to empower you every step of the way!
