Colorectal cancer is now the leading cancer killer in adults under 50, and patients in their 20s are presenting with metastatic disease that has nothing to do with family history. Most physicians are still telling young patients with rectal bleeding that it's probably just hemorrhoids and that's costing lives. In this episode, Dr. Gabrielle Lyon sits down with Dr. Michelle Pearlman, a board-certified gastroenterologist and founder of a Miami-based gastro-metabolic clinic, to discuss: The specific warning signs every adult under 50 should never ignore, regardless of age including rectal bleeding, unintentional weight loss, and persistent abdominal painWhy GLP-1 medications like Ozempic and Zepbound are being miscategorized as weight loss drugs when they're actually metabolic reprogrammers with applications in fatty liver, sleep apnea, and inflammationThe protein, fiber, and resistance training protocol Dr. Pearlman uses to protect muscle mass in patients on GLP-1 therapyHow hormone replacement therapy combined with GLP-1s is changing body composition outcomes for perimenopausal women and why current guidelines are still 20 years behind the dataDr. Pearlman's personal osteoporosis diagnosis at 39, despite being a lifelong bodybuilder, and what it revealed about the diagnostic gaps in standard medicine This conversation gives you the framework to recognize the warning signs most physicians are still missing, and the foundational habits; nutrition, resistance training, and hormone optimization that protect your gut, bones, and muscle through midlife and beyond.
