The Insulin Playbook: Basal vs. Bolus & How to Fix Your Dosing

Welcome to The Diabetes Podcast! If you or a loved one takes insulin for type 2 diabetes, this episode is your ultimate masterclass. Amber and Richie dive deep into the mechanics of insulin dosing, moving beyond the basics to explain how insulin truly works as a medication within your body's complex system. Remember, elevated blood sugar is the output—the fever—not the disease itself. In this episode, we explore why simply increasing your long-acting insulin might be the wrong move and how the "over-basalization trap" keeps you frustrated. We break down the critical difference between basal (background) and bolus (mealtime) insulin, and why relying on a reactive sliding scale often leaves you chasing high blood sugars. You'll also learn the essential math your doctor might not have taught you, including your Total Daily Insulin (TDI), the 1700 rule, and the 450 rule, so you can walk into your next appointment informed and confident.
