Continuous
Glucose Monitoring
at AEOM

Most patients describe a brief moment of pressure or a small pinch during fitting — over in under a second.
After fitting, the sensor produces no sensation; most patients forget they're wearing it within a few hours. If sensor pain persists beyond initial fitting, we'd remove and reposition; this is uncommon.

Yes — modern CGM sensors are designed to be water-resistant and exercise-compatible. Showers, swimming, gym sessions, sports — all fine. Some patients use an additional adhesive patch over the sensor for extra security during intense activity or swimming.

Sensor adhesion is generally excellent, but occasionally a sensor can come loose — typically with very intense activity, very hot weather, or unusually sweaty conditions. If this happens, contact us; we'll replace the sensor (typically at no charge if it's within the first few days) to ensure you get the full 14 days of data.

CGM provides strong indicative data — patterns of high glucose spikes, elevated fasting glucose, poor time in range can all suggest pre-diabetes or undiagnosed diabetes.

But formal diagnosis requires standardised testing (HbA1c, fasting glucose, oral glucose tolerance test) interpreted clinically. If CGM patterns suggest diabetes or pre-diabetes, we'd recommend appropriate diagnostic bloodwork and, where appropriate, referral to your GP or a diabetes specialist.

The honest answer is: the evidence is developing rather than fully established. CGM is genuinely evidence-based for diabetes management. For non-diabetic wellness use, the clinical evidence is growing but the published research is less mature. We use CGM because the patient outcomes — particularly behavioural change in response to data — are typically meaningful. We don't claim more than the evidence supports.

This is more contested than influencer content suggests. Broadly, current thinking is that maintaining glucose mostly between 3.9–7.8 mmol/L (70–140 mg/dL), with minimal time above 10 mmol/L (180 mg/dL), aiming for spikes under 30–40 mg/dL (1.7–2.2 mmol/L) above baseline is reasonable. But specific numbers vary by individual; the more useful question is "what's typical for you, and what changes that?" — which is what CGM shows.

Yes — consumer CGM is increasingly accessible, and for patients comfortable interpreting data independently, it's a reasonable approach. AEOM's value-add is the clinical interpretation, the integration with bloodwork and wider care, and the structured consultation around findings. If you want CGM without consultation, consumer platforms are appropriate. If you want CGM as part of considered clinical care, AEOM is the right setting.

One sensor lasting 14 days. Most modern CGM sensors (FreeStyle Libre 3, Lingo, Levels) are designed for a 14-day wear time. If you'd like 28 days of monitoring (capturing more variability — particularly useful around menstrual cycle effects or stress periods), the Extended CGM Programme provides two consecutive sensors.

With your consent, yes — we can share the data and our interpretation with your GP. This is particularly useful where CGM findings suggest pre-diabetes or undiagnosed metabolic dysfunction that should inform ongoing NHS care.

CGM is generally safe in pregnancy. If you're pregnant or breastfeeding, we'd discuss timing and appropriateness at consultation — gestational diabetes screening pathways through your obstetric care may be more appropriate for clinical questions, with CGM as supplementary information rather than primary diagnostic.

This requires honest discussion. Glucose-watching can become problematic for patients prone to dietary obsession or restriction. We screen for this at consultation and may recommend not proceeding — or recommend doing CGM only with concurrent support from a relevant clinician. Patient wellbeing matters more than the data.

Yes — the data is yours, and you're free to share with anyone you choose. If you're working with a trainer or nutritionist outside AEOM, we'd encourage coordinated interpretation rather than parallel advice; we can be involved in this conversation if useful.

Several options. You can book a Repeat CGM Programme at AEOM (£395 within 12 months) for a follow-up assessment. You can transition to a consumer platform (Lingo, Veri, Levels) for ongoing self-monitoring at your own discretion. Or you can stop after the initial programme — many patients find the 14-day data gives them everything they needed and the behaviour change persists without ongoing monitoring.

Our clinic is at 116 Seymour Place in Marylebone, London.

Marylebone, Baker Street and Edgware Road stations are all under ten minutes on foot. Free street parking is available after 6.30pm, with paid bays on York Street nearby — daytime parking is reimbursed for treatments over £200. Treatments are by appointment only.
