Continuous Glucose Monitoring

A continuous glucose monitor is a small, painless sensor worn on the back of your upper arm. A flexible filament sits in the interstitial fluid just under your skin and measures your glucose level continuously, day and night, for two weeks.

The data streams to your phone in real time and gives you a complete picture of how your glucose actually behaves — not just a single fasting number from a lab draw, but every meal, every workout, every poor night of sleep.

Application is quick and essentially painless. You can shower, swim, sleep, and exercise normally with the sensor in place.

Glucose tolerance is one of the central drivers of long-term metabolic health. Even in people whose fasting glucose and HbA1c look fine, large glucose excursions after meals — and patterns of insulin resistance early in the morning, after stress, or after poor sleep — can signal early metabolic dysfunction years before it would show on standard labs.

More immediately, individual glucose responses to identical foods vary enormously. Two patients eating the same bowl of oatmeal can have completely different curves. CGM removes the guesswork and replaces it with personal data — which foods, in which combinations, at which times of day, fit your physiology.

It's also one of the most behavior-changing tools in medicine. Seeing your glucose react in real time tends to make abstract advice about nutrition, sleep, and exercise feel concrete in a way that nothing else does.

• Time in range, time above range, and time below range
• Glucose variability and standard deviation
• Postprandial peaks and the duration of excursions
• Overnight glucose patterns and the dawn phenomenon
• Glucose response to specific foods, training sessions, and stressors

• Anyone with a family history of type 2 diabetes who wants to identify early metabolic dysfunction.
• Patients with weight-loss-resistant central adiposity, fatigue after meals, or symptoms suggestive of insulin resistance.
• Active patients optimizing nutrition for performance, training, or body composition.
• Anyone curious about how their unique metabolism responds — there's almost always something useful to learn.

• You wear it for 14 days, going about your normal life. The sensor connects to your phone via the manufacturer's app.
• We ask you to log meals, workouts, and notable events during the wear period. The richer the log, the more useful the analysis.
• At your next follow-up, we identify the highest-leverage changes and translate them into a practical plan.

We look at the patterns more than the individual numbers — average glucose, variability, time in range, the shape and duration of postprandial peaks, and whether overnight glucose looks healthy.

We then map glucose patterns onto your meals, training, and sleep to identify the changes that will produce the largest improvement. The goal is rarely strict glucose control — it's understanding your physiology and using that understanding to eat, train, and sleep better.

Most patients learn more about their nutrition from two weeks of CGM than from years of dietary advice. For some, we'll repeat the wear after a few months to confirm the changes are working.
