What Metformin Actually Does To Your Body - A Nurse Explains

Metformin is the most prescribed diabetes medication in the world. Hundreds of millions of people take it every single day. And almost none of them know how it actually works, why it causes the side effects it does, or why researchers are now studying it for aging, cancer, and heart disease. I am a registered nurse and my advocacy is to make sure that health education doesn't stop at the clinic door. In this video I break down exactly what metformin does inside your body, how it actually lowers blood sugar, what the real side effects are and how to manage them, and what the emerging research is showing about metformin beyond diabetes. We cover the four mechanisms of how metformin works including reducing liver glucose production, improving insulin sensitivity, slowing glucose absorption from the gut, and its effects on the gut microbiome. We also cover why metformin does not cause low blood sugar, how to manage gastrointestinal side effects, the rare but serious risk of lactic acidosis, why long term metformin use depletes Vitamin B12, and the exciting emerging research on metformin and aging through the TAME trial, metformin and cancer prevention, and metformin and cardiovascular protection. If you take metformin every day and have never fully understood what it is actually doing inside your body, this video is for you. 🔔 Subscribe for weekly health education from a registered nurse. ⚠️ DISCLAIMER: This video is for educational purposes only and does not constitute medical advice.
