Your Blood Sugar Target After 70 Isn't What You Think Too Low Can Be More Dangerous

For years the rule was simple: the lower your blood sugar, the better. But for many people over 70, the major diabetes guidelines now recommend gentler targets, because low blood sugar can cause falls, confusion, emergency visits and has been linked to dementia. In this video, we go through the published research and the official guidelines, in plain language, so you can have a better conversation with your doctor. In this video you'll learn: • What your A1c really measures and what it can hide • The American Diabetes Association's A1c goals for older adults: healthy, complex and very complex health • What the ACCORD trial taught doctors about pushing blood sugar too low • The quiet signs of low blood sugar in older adults that are easy to miss • Which diabetes medicines are most likely to cause lows (insulin, glipizide, glimepiride, glyburide) • What the Beers Criteria say about sulfonylureas and sliding-scale insulin • The 15-15 rule for treating a low, and when to call for help • The exact questions to ask your doctor about your personal target ⏱️ TIMESTAMPS 0:00 The number you've been chasing 3:51 What A1c actually measures 5:14 What the guidelines say for older adults 7:54 Why lower isn't always better — the ACCORD trial 10:07 What low blood sugar does to an older body 13:44 Which medicines cause lows 17:15 How to spot and treat a low 20:15 What happened to Frank 22:38 Your checklist and questions for your doctor 📚 RESEARCH & REFERENCES 1.
