Curated, not stocked.
Blood sugar data from a single fasted test misses almost everything that matters — it tells you where you are at one moment, not how you got there. We recommend the Lingo CGM because two weeks of continuous glucose data consistently reveals patterns our clinicians can actually act on: post-meal spikes, nocturnal dips, stress responses. It is one of the few consumer-grade tools that meaningfully changes the clinical conversation rather than adding noise to it.
About this product
Lingo CGM (2-week)
The Lingo CGM is a continuous glucose monitor worn on the upper arm that tracks your blood glucose levels in real time across a two-week period. Rather than a single fasted reading, it maps how your glucose responds to meals, sleep, stress, and exercise — patterns that a snapshot blood test simply cannot capture. That data gives you and your clinician a far more nuanced picture of your metabolic health.
It suits anyone who wants to understand how their diet affects blood sugar, from people who have been flagged with borderline insulin sensitivity to athletes optimising fuelling strategies around training. It is also well suited to individuals who experience energy crashes, persistent fatigue, or difficulty managing weight, where glucose variability is a plausible but unconfirmed factor.
Wearing a CGM for two weeks is generally considered the minimum period needed to identify meaningful patterns across varied days — workdays, rest days, different meal types. The Lingo device pairs with an app that presents the data in accessible trend graphs, helping you make specific, evidence-informed adjustments rather than guesses.
This is not a diagnostic medical device in the clinical sense, but it is the same sensor-based technology used in continuous metabolic monitoring. For most users, the value lies in the data it hands back to you — concrete, personal, and actionable with the right clinical support.

Common questions
Frequently asked
Do I need a prescription to use this CGM?
The Lingo CGM is available as a consumer device and does not require a prescription in the UK. That said, if you have a diagnosed metabolic condition such as diabetes, speak to your GP before using it, as clinical-grade monitoring may be more appropriate for your situation.
Does it hurt to apply or wear?
The sensor is applied with a small applicator that inserts a fine filament just under the skin. Most users report minimal discomfort on insertion and little to none during the two-week wear period. Skin sensitivity can vary, so check the instructions for guidance on placement and removal.
What does the data actually show me?
The companion app displays your glucose as a continuous trend line, showing how levels rise and fall in response to food, activity, stress, and sleep. This lets you identify which meals cause sharp spikes, how long your glucose takes to return to baseline, and whether your levels are stable overnight.
Who would benefit most from wearing a CGM?
It is particularly useful for people with borderline insulin sensitivity, unexplained energy crashes, difficulty managing weight, or those who want to optimise nutrition around sport or demanding work schedules. It is also a practical tool for anyone whose blood panel has raised questions that a static reading cannot resolve.
Is one two-week sensor enough to draw useful conclusions?
Two weeks is generally considered a sufficient window to capture patterns across varied days — different meals, training days, rest days, and sleep quality. For many people a single two-week session provides enough data to make meaningful dietary adjustments, though some users choose to repeat it after making changes to track progress.
