Transparency: This blog has never worn a Dexcom sensor or any other CGM. There are no first-party readings here. The article is based on Dexcom’s shop pages (accessed 14 Oct 2026), press releases, safety notices from Germany’s BfArM and Spain’s AEMPS, a pivotal accuracy study and the JAMA review from August 2026. All sources are listed at the end. This article contains no affiliate links. More on methodology
Key points
- Available in Germany: Dexcom G7 and Dexcom Flex, both only through Dexcom’s webshop. No prescription according to the shop, but you need a Dexcom account.
- Not available in Germany: Stelo, Dexcom’s sensor for people without diabetes. It is sold only in the US.
- Intended use: The G7 is built for people who inject insulin several times a day. The Flex is for adults with type 2 diabetes who are not on intensive insulin therapy. Neither is meant for healthy people.
- Cost: G7 works out to €8.97–9.90 per day, Flex to €4.22–4.66 per day.
- Benefit for healthy people: not shown, but not disproven either. The JAMA review from August 2026 finds only “limited and indirect evidence” even for prediabetes.
- Current (October 2026): unconfirmed hacker claims against Dexcom, a safety notice for the G7 app, and Q3 results on 29 October.
What Dexcom sells in Germany
Dexcom (DexCom, Inc., Nasdaq: DXCM) was founded in 1999 and is headquartered in San Diego. Its German subsidiary is Dexcom Deutschland GmbH in Mainz. The German webshop lists exactly two sensors: G7 and Flex. The older G6 has been out of production since 1 July 2026.

Prices incl. VAT per Dexcom’s German webshop and stelo.com, as of 14 Oct 2026. The per-day figures are our own arithmetic and assume every sensor lasts its full wear time; the grace period is not counted.
Dexcom G7: the sensor for insulin users
The G7 is Dexcom’s main product. It sends a reading every five minutes to a phone, a receiver or directly to the Apple Watch, and it connects to insulin pump systems. Dexcom’s German webshop describes it as the sensor “for people who inject insulin several times a day”.
There is a pivotal accuracy study (Garg et al., Diabetes Technology & Therapeutics, 2022): in 316 adults with type 1 or type 2 diabetes, the mean absolute relative difference from the lab reference (MARD) was 8.2% on the upper arm and 9.1% on the abdomen. Important for healthy users: these numbers come from people with diabetes.
A 15-day version of the G7 exists in the US. Dexcom’s German webshop lists only the 10-day sensor, and according to Diabetes-Anker Dexcom has not given a German launch date for the 15-day version.
Dexcom Flex: the cheaper Dexcom for type 2
The Flex has been on sale in Germany since 16 July 2026; Germany was the first market. It lasts 15 days, weighs 3.3 g and is waterproof according to Dexcom. Readings go to the Flex app or to a separate receiver (€69.90), or both at once.
On its product page Dexcom says the Flex is suitable if “you live with type 2 diabetes and do not use insulin or only receive basal insulin”. The launch press release names adults 18+ with type 2 diabetes who take basal insulin, tablets or GLP-1 drugs. People without diabetes do not appear in either description.
According to the patient association Diabetiker Niedersachsen, Dexcom is promoting a discounted 30-day trial for new customers with type 2 diabetes until the end of 2026.
Stelo: the Dexcom for healthy people, but US only
Stelo is Dexcom’s over-the-counter sensor for adults who do not take insulin, which includes people without diabetes. It is sold only in the US:
- stelo.com has no country page for Germany, the UK or Australia; those addresses return a 404 error (checked 14 Oct 2026).
- According to Oura, the Stelo app is only available in US app stores.
- Oura’s glucose feature with Stelo is “available only in the US”, per Oura support. The former German Oura shop page for Stelo now redirects to exactly that support article.
According to industry reports from May and June 2026, Dexcom plans to launch Stelo in the UK, Australia, New Zealand and South Korea. Germany is not on that list. A US import fails at the app.
Correction: Several older articles on this site said Stelo could be ordered via Oura’s German shop. That was wrong and has been corrected as of 14 Oct 2026.
Can I buy a Dexcom as a healthy person?
The G7 and Flex shop pages list no prescription requirement, but they do say “Dexcom account required”. Whether Dexcom asks about a diagnosis when you open the account is not stated on the pages. We have not tried it.
The intended use matters more. A CGM is a medical device. Wearing one without diabetes means using it outside what the manufacturer built, tested and labelled it for. In practice:
- The accuracy data applies to people with diabetes. There is no Dexcom study in healthy people.
- The apps are built for therapy. Alerts, target ranges and reports are designed around hypoglycaemia and insulin, not around what your breakfast does to your curve.
- Insurance will not pay. In Germany, reimbursement for real-time CGM is tied to insulin-treated diabetes.
That is not a prohibition. It is context: you are buying a diabetes tool, not a biohacking gadget.
Does a CGM do anything for healthy people?
Honest answer: nobody knows. The review “Continuous Glucose Monitoring in Type 2 Diabetes and Beyond” (Dower et al., JAMA Internal Medicine, 3 August 2026) says this about the groups closest to healthy people:
“Only limited and indirect evidence supported the adoption of CGM in people with type 2 diabetes not receiving glucose-lowering therapy or in those with prediabetes or obesity.”
Metabolically healthy people do not appear in the review at all. That is a gap in the evidence, not proof that CGMs are useless. The studies Dexcom cites for the Flex come from type 2 diabetes care and cannot be transferred to healthy people.
If you measure anyway, treat it as a bounded self-experiment: two to four weeks, one clear question (for example: how do I respond to oats versus eggs?), then stop. What a CGM does not replace: an HbA1c test from your doctor if you are worried about your blood sugar.
What is going on at Dexcom (as of 14 Oct 2026)
Dexcom has been showing up noticeably often in searches since early October 2026. We did not find a single event that clearly explains it. These items fit the timing:
1. Hacker claims, unconfirmed. The extortion group ShinyHunters added Dexcom to its leak site on 1 October and threatened to publish data (Cybernews). On 10 October a second group called Redact claimed a ransomware attack on Dexcom’s US operations. According to MedDevice Cyber, neither group published data samples, and Dexcom has not confirmed an incident (as of 12 Oct). Three proposed class actions were nonetheless filed in the US between 2 and 6 October. These are allegations; no court has ruled. There is currently no confirmed impact on users in Germany.
2. Safety notice for the G7 app. On 16 Sep 2026 Germany’s BfArM published a manufacturer notice (reference 39037/26): in G7 apps for iOS, Apple Watch and Android before version 2.12, critical alerts may not vibrate in Do Not Disturb mode, and some system alerts may stay silent for up to 25 minutes. According to Dexcom, no serious injuries occurred. The fix is the app update. Spain’s AEMPS followed on 6 Oct 2026 and describes a second issue: in iOS version 2.12, non-critical alerts may not sound in silent or Focus mode.
3. Stolen scrap sensors (June 2026). According to Dexcom, two G7 lots that were meant to be destroyed as scrap were stolen and sold in the US by an unauthorised distributor. The affected lots are 1725204004 and 1725069002. According to the safety notice (BfArM reference 22117/26), small quantities were also sold outside the US. Products from authorised channels are not affected. You can check your serial number at dexcom.com/theft-check.
4. Dates. Dexcom reports Q3 results on 29 October 2026. The G6 has been out of production since 1 July 2026.
What are the alternatives in Germany?
The two sensors that are explicitly built for people without diabetes, Stelo and Abbott Lingo, are not officially sold in Germany. What remains:
- FreeStyle Libre 3 Plus (Abbott): available from pharmacies and from Abbott, 15-day wear, €70.60 per sensor on Abbott’s subscription (€4.71 per day). It is a diabetes product too. Important: Libre 3 and Libre 3 Plus are under an FDA Class I recall (falsely low readings), and Germany is in scope. Check the serial number in the lot checker before applying a sensor. Details in our Lingo vs Libre 3 Plus article.
- Dexcom Flex: the cheapest Dexcom per day, but with a type 2 intended use (see above).
- Abbott Lingo: US and UK only.
For more on whether CGMs make sense without diabetes at all, see our Libre 3 guide for non-diabetics.
Verdict
If you search for “Dexcom” in Germany and do not have diabetes, the short answer is: the Dexcom built for you is called Stelo, and you cannot get it here. You can order the G7 and Flex from the webshop, but both are diabetes products. Per day, the Flex costs half as much as the G7 and lasts 15 instead of 10 days. Whether a CGM is worth it for healthy people at all is an open question. If you try one, plan it as a short experiment with a clear question.
The hacker reports around Dexcom are so far claims without evidence. What G7 users can actually do: update the app.
