Can a CGM diagnose insulin resistance or prediabetes?

No. The sensor shows glucose patterns in everyday life, but it is not a diagnostic method. Prediabetes and diabetes are diagnosed with fasting glucose, HbA1c and the glucose tolerance test; sensor data is additional information interpreted by a physician.

What is a continuous glucose monitor (CGM)?

A small sensor on your upper arm measures interstitial glucose every few minutes for 14 days. Your phone app shows how food, sleep, activity and stress affect your blood sugar.

Does placing the sensor hurt?

Placement takes a couple of minutes and most people feel only a slight prick. The sensor stays on with an adhesive patch, and you can shower and exercise with it on.

Do I need to do anything myself?

Live your normal life and log your meals and workouts in the app. That’s exactly what makes the data interpretable.

Is CGM suitable for treating type 1 diabetes?

No. This service is meant for understanding lifestyle and metabolism. For type 1 diabetes management, use the system prescribed by your treating physician.

Is CGM included in any package?

Yes — 14-day CGM is included in the metabolic package and the 90-day health optimisation programme. Otherwise it can be added to a consultation or follow-up; sensor placement cannot be booked separately.

Continuous Glucose Monitor (CGM) - 14 days of your metabolism

Q: What’s included in the price?

The sensor, placement, app setup, 14 days of monitoring and clinical interpretation. CGM is an add-on to a consultation or follow-up; the appointment is billed separately. Data is shared with the clinic through a secure channel.

A continuous glucose monitor tracks your blood sugar around the clock for two weeks. The result isn't just a graph – it's a clinical interpretation of what's actually driving your curve and which changes will give you the most benefit.

What you'll learn

See your real curve

A single blood-sugar reading shows only a moment. 14 days of continuous tracking reveal a pattern – mornings, nights, post-meal spikes.

Your personal food reactions

The same food affects people differently. The sensor shows which meals cause a sharp spike and the fatigue that follows for you.

Sleep, stress and activity

The data also reveals nighttime levels, post-workout effects and the impact of stress – making lifestyle changes concrete.

Clinical interpretation

The doctor interprets sensor data in the context of your health and risk factors. Share data with the clinic through a secure channel, not ordinary unencrypted email.

What recent studies show in people without diabetes

Three 2024–2025 papers looking at sensor use in people without a diabetes diagnosis. These are scientific references, not a promise of outcome – your data is always interpreted by a physician.

2024 · Nature Medicine

Continuous glucose monitoring and morning blood-sugar fluctuation

8,315 adults without diabetes (ages 40–70) wore a sensor. One person’s morning fasting glucose fluctuated so much from day to day that a single lab test can give a random snapshot – continuous monitoring shows the real average.

2025 · Journal of Diabetes Science and Technology

Which sensor metrics distinguish normal blood sugar from prediabetes

Sensor data from people without diabetes showed that average glucose and daily variability differ before a standard test (HbA1c) changes. This helps spot an early trend toward prediabetes.

2025 · Cureus (systematic review)

The sensor as a lifestyle-change tool in people without diabetes

A review of studies where people without diabetes used a sensor to adjust diet and activity. The authors conclude that immediate feedback supports lifestyle change, but stress that data needs clinical interpretation and the evidence base is still limited.

Paid separately: Blood tests and the nutrition plan are not included

Who this service is not for

Being upfront saves your time and money. This service is not the right choice if:

If you have type 1 diabetes and need sensor monitoring for treatment – that goes through your treating physician.
If you will not log meals and activity for 14 days – the curve cannot be interpreted without context.
For acute problems (severe pain, fever, breathing difficulty, injury) – contact your GP, an on-call doctor or the emergency department.
If you expect a replacement for diagnosis and treatment – we work alongside your GP and specialists, not instead of them.
If you only want a prescription or a certificate without an assessment – we do not issue those at a prevention visit.
