Why CGMs Reveal Blood Sugar Patterns A1C Misses | Diabetes Prevention & Metabolic Health

In this episode of The Living Life Well Show, Dr. Jon Skelton breaks down a landmark study from Diabetes Care showing how continuous glucose monitors (CGMs) reveal blood sugar patterns that fasting glucose and A1C completely miss β€” even in people without diabetes.

A1C and fasting glucose have long been the standard tools for diagnosing and monitoring diabetes. But are they telling the whole story? A recent study of 1,356 adults without diabetes found that glucose variability β€” the spikes, crashes, and daily fluctuations β€” was associated with a 21–26% higher odds of high blood pressure and dyslipidemia, even when fasting glucose looked normal.

In this episode, you'll learn:

- **Why a "normal" A1C doesn't rule out blood sugar issues** β€” and how glucose variability may be the missing piece in diabetes prevention
- **How CGMs work** and what they reveal that a single blood draw simply cannot
- **The study's key findings** on cardiometabolic risk in adults without diabetes β€” including the significance of time spent above 140 mg/dL
- **What glucose patterns mean for diabetes remission** and how recognizing patterns can change behavior and lower risk
- **How thyroid function connects to metabolic health** β€” and why a thorough thyroid evaluation matters when glucose, cholesterol, or weight feel "off"
- **The gut health link** β€” how low levels of Akkermansia and Faecalibacterium may contribute to insulin resistance, leaky gut, and blood sugar swings
- **Study limitations** explained honestly β€” cross-sectional design, short monitoring window, demographic constraints, and why causation isn't proven
- **Dr. Skelton's practical approach** to using a CGM as an educational tool: observe, indulge, then optimize β€” and why no single lab value defines your health

Whether you've been diagnosed with diabetes, are working toward diabetes remission, or simply want to understand your metabolic health on a deeper level, this episode explains why blood sugar patterns matter far more than any single number β€” and how CGMs, thyroid testing, and gut health all fit into the bigger picture.
