Obesity, Hormones, and the Vicious Cycle of Sleep Apnea

Obesity and sleep apnea create a loop that reshapes metabolism, hormones, and airway function long before most patients notice the signs. In this episode of Vital Discourse, Dr. Ben Cilento and Dr. Lee Mandel explain how fragmented REM sleep disrupts growth hormone, leptin, and ghrelin, lowers metabolic rate, and drives weight gain that feels impossible to reverse. They break down how fat in the tongue, neck, and belly changes airway physics, how inflammation and insulin resistance add strain, and how GLP-1 medications, testosterone, CPAP, surgery, and weight programs fit into a coordinated plan designed to restore both breathing and metabolic health.
