The only reason I can think of is: supply is short and they need to be preserved for diabetics.
But if supply is not short, why should I need to go through a gatekeeper to measure my own biometrics?
Same with glasses. If I want to buy a pair of glasses with arbitrary optical properties, why shouldn't I be able to?
Seems like the medical world is sometimes a bit too paternalistic, probably to keep themselves cemented as middle men, like a car dealer preventing consumers from buying directly from source.
To be fair, certain things are dangerous and probably should be gated behind a doctor for safety reasons, but sometimes I think Rx fever gets a bit out of hand.
I'd rather make my own choices, thank you very much.
This is extremely condescending and also very profitable for the medical industry. On the one hand we have a wild west market where hospitals, pharmaceuticals and doctors can see all data and charge whatever prices they feel like. For the patient it's a market where we aren't even allowed to collect data about ourselves, aren't allowed to import drugs that are approved and safe somewhere else and with many treatments we won't even get an price before it's done. But we have to pay. Talk about asymmetry!
Speaking of self diagnosing: I went to several doctors about my joint pain and chronic headaches. they all wanted to describe steroids, anti inflammatories and whatever. Turns out if I reduce sugar, I am totally fine. I came up with that after reading some literature and testing on myself. None of the doctors mentioned this for the hundreds of dollars in deductible and copay this cost me. Self diagnosis works. I know there are limits to this but many of us can read the medical literature as well as doctors and draw our own conclusions.
Speaking of joint pain, also consider:
1. Avoiding microplastics. Wash everything and filter your water, but not with a resin based filter that leaks more plastics than it removes. Avoid contact of food and drink with plastic.
2. Sometimes it's due to gut dysbiosis. In fact this goes hand in hand with the sugar theory. Antibiotics can often fix it, although the exact antibiotic needed can vary significantly.
Don't sites like Zenni Optical already offer this?
It's an American company. AFAIK there is no regulation in the US that requires prescription from a doctor to get the glasses.
.33 of 1.15 was amazing for computers, comfortable but I can still look at distance somewhat
There was an option to upload my prescription, so they could auto-detect the values from it. But there's a button just below that for "manually enter". I never saw any other prompts, on the way to checking out.
Fwiw, it would be very hard for the government to correctly investigate and accurately prove in court, since it will require a statistical proof over many patients that get tested at both good and bad places.
You state this like it is standard practice, like all opticians do this. What evidence do you have?
> Seems like the medical world is sometimes a bit too paternalistic
The charitable explanation is this: why would you want to measure those specific biometrics in the first place? Normies normally don't do stuff like that. Do you suspect you may have some medical issue that those biometrics would help you diagnose? Did someone tell you that, or did you read about it on-line? If the answer to those last questions is "yes", then the system really wants you to visit an actual doctor before you go out on your own and hurt yourself (and/or get scammed while also hurting yourself). It's not that they're worried a glucose monitor - or any other measurement tool - will kill you; it's just that it's hard enough to get people to visit the doctor over literally anything, from inconveniences to immediate life threatening dangers, so the system takes every opportunity to nudge you to cross paths with it.
Maybe this attitude needs to stop. Get people more engaged with their health while collecting data so they can show up to their doctor with more information.
We don’t shut down the sale of car parts because Normies don’t normally do their own car repairs. Even if only a small But passionate group takes control of their health data collection, why stop them?
> We don’t shut down the sale of car parts because Normies don’t normally do their own car repairs.
We actually have done this, across industries. And now we have a "right to repair" movement because people realized their freedoms were curtailed.
It's important that we don't disrupt people's ability to learn about their own body. Some things are a health risk, and we want to prevent scams, but we shouldn't lock people out behind expensive and bureaucratic gate keepers.
The difference is that for tests requiring doctor requisitions that is the government locking down access, whereas right to repair is laws preventing companies from locking down access (to increase their profits)
Realistically, the medical community is extremely gate-keeper oriented. The doctor shortage is entirely fabricated by organizations run by doctors. Some barrier to providing medical care is good, of course.
Realistically, we don’t have a lot of data on the blood glucose levels of healthy people. The explosion of Fitbit’s and Oura rings and similar products gave us an explosion in data on basic vitals of millions of people during sleep. This can inform a ton of research, even if the quality of data is not as high as in a clinical setting. The difference between collecting 40 hours a week of data on 5 people vs 40k hours on 5k people (or more!) is huge in a research setting.
I used to work doing ML to measure and improve athletic performance, and to measure and detect physiological strain and risks during physical exercise. Our limitation was always access to enough data to not overfit. Compared to data corpus’s using in “generative AI” or image recognition models, or any other number models that are now standard in industry, we’re still in the Stone Age.
Plus, the whole host of problems that occur when there's too much or too little insulin in your body. Comas and death in both directions! For better or worse, having certification and a professional watching after it is not the worst thing for a newbie on a dexcom monitor.
We've had the devices for almost 20yrs, just not available over-the-counter.
> the whole host of problems that occur when there's too much or too little insulin in your body
Which healthy bodies regulate. This device does NOT administer insulin, and it's not a tool for insulin administration in any way. This tool is only approved for use for people who do NOT have insulin prescriptions. This is a tool for healthy people to monitor their levels.
I guess the thing is that in countries where there is universal healthcare, gating is necessary to contain costs for patients who don't have a medical need. In countries without universal healthcare, the downside of prescription->OTC is shifting costs onto the patients where insurance may not cover them.
It's pretty cool, completely painless to implant (didn't even realize it went in), but made my arm surprisingly sore for a few day. I don't think the science of interpreting glucose levels is clear and deterministic enough to find actionable insight from the data unless you're generally concerned about being pre-diabetic. Seeing a glucose spike isn't bad, and not seeing a spike isn't bad. If you're not diabetic or pre-diabetic, your body will adjust and maintain homeostasis, so the data isn't particularly actionable. Oh and the packaging has a TON of waste. Each sensor comes with a single-use applicator which a prescription user would re-use for months.
PS - I’d love to see better and more accessible monitors or testers for things that your body can’t self regulate as easily, like cholesterol levels.
First, I'm not "undergoing treatment" so I don't think my negative perceptions would cause anything to have a worse efficacy (which is my understanding of "nocebo").
Second, I think that measurement is ok (great even) as long as you have correct expectations. Doctors will often say that you shouldn't get tests unless undergoing a differential diagnosis from a doctor, because tests all have ranges, and slightly off results can freak out patients who are otherwise healthy. Frankly, I assume it's actually a cost/effort thing. I disagree because (1) you have to wait until something is wrong before getting a test and (2) its would good to have a baseline level of <thing> for when something goes wrong to avoid red-herrings.
If you have a mole or lump, a doctor would not recommend you undergoing surgery, or even get an invasive biopsy unless it's really scary looking at start. Many/Most are benign. BUT a doctor generally would suggest you watch it regularly in case it changes. Clearly monitoring benign-looking things is good, because it can become less benign or it can be a symptom of something dangerous.
Concretely, I'm a very healthy and active individual, but also a vegetarian. Vegetarian diets can easily be vitamin deficient, so I get tested. Doctors generally don't want to test me because I "clearly look healthy and don't have symptoms of deficiency". But I was absolutely deficient for years, and while I felt fine, supplementing for my deficiency showed me I could feel better than before.
I think you need to go in with the right perspective, and I think the setting of doctors only offering tests when there is something wrong sets the tone that they catch dangerous things. Imagine if blood testing were available at gyms (not a suggestion, just an example) - the data would be viewed very differently. Imagine if doctors’ offices had treadmills, you’d view exercise very differently too.
If your X metric is a bit outside of a normal range, it doesn’t mean you’re going to die or you can’t handle some biological function (generally). It means it may be more strenuous for your body, or you’re predisposed to issues when something else goes wrong, or your body is simply a bit outside “normal”. It’s like someone who is really tall - being tall is “not normal” but it’s generally recognized as not deadly, despite the reality that certain health issues are correlated with abnormal height.
A huge portion of glucose management (even for diabetics) is the actual trend of the data vs the actual blood glucose levels. These CGMs capture trends correctly, even if the absolute value is off. A prescription variant would have periodic calibrations as an option. If you eat a meal that spikes blood glucose level, the CGM probably won't smooth out a peak, so you'd still see the magnitude of the effect. The other thing to consider is that when read from the arm or a "fleshy" bit, a change in glucose level is about 20min delayed from blood levels.
The healthy range for a non-diabetic is ~70-140 mg/dL, and your body regularly can swing up more than +50mg/dL after a meal. This is a pretty big range and swing, and being 15% off (in either direction) is not particularly problematic. Your bodily response to the same meal can vary more than 25%. One test I did do is consume "glucose tablets" (which are basically candy), they're products meant to spike your blood sugar (for diabetics who get "low"), and all you can predict is that my levels go "up fast". Again, all that matters is the trend, especially if your body can self-regulate.
The FDA does study how accurate these products are, and they conform to certain expectations. That said, you're not wrong that it can be 25% off sometimes. According to a study (linked below), ~99% of the time, the device is within 30% of clinical test levels, and about 90% of the time, the device is within 15%.
Not sure if this overlaps with your interest, but you can now self-order tests from mainstream labs. e.g. [1].
Personally I think this cuts into the attractiveness of single-purpose devices. You can order a whole bunch of tests with one blood draw, and selectively only repurchase those that need monitoring over time. You're also likely getting higher-quality data in both the average and worst cases.

Same issue as before. The medical establishment always trying to find a way to get a cut on everything when it’s entirely unnecessary.
I don't think it has the same use cases as at-home monitoring devices though. To use the example of cholesterol, you can be morbidly, dangerously high in your LDL levels, where doctors will put you on medication that day and warn you to basically stop eating. But you can also just have levels that are high - but where lifestyle change alone is effective. Ideally, you'd want to be able to reflect daily/weekly and adapt. The tighter that feedback loop, the better.
Quest charges $70 for a cholesterol panel, which for many, is too high for a regular purchase to build a positive feedback loop. Its probably in the "purchase quarterly" and maybe "monthly" range, but I doubt many would be able or willing to go weekly.
As recently as three months ago, Dexcom's G7 app made hundreds of daily connections both to dexcom's own servers and third party metrics servers. Note that this was the case regardless of whether you opted out of their online services (like sharing).
I checked my firewall logs before I posted this comment, and suddenly I no longer see these queries. Since I have two years history of monitoring and blocking similar Dexcom traffic, it's hard for me to believe they actually stopped.
I would welcome stronger laws to stop this sort of behavior. I'm essentially a captive audience to a maker of expensive medical gear, and it's a lousy feeling to have them slurping up data about me every time I check my blood sugar.

...and many, many others. Dexcom: slurping up patient data because hey they can.
Both assays have value but they're really for different purposes
Needing to get such feedback from diet is completely unnecessary. It is very easy to estimate the rise in glucose using these factors: percentage of fiber, how processed the food is, how it was cooked (high-heat (bad) vs low-heat (good)), whether the carbs are complex carbs (fibrous) or simple carbs (starch), and whether the meat is red or white.
> variance in the hemoglobin turnover period
Whether there is variation or not, it is still the thing to optimize. Your point is like saying there is significant turnover of how people spend money, so they don't have to bother looking at their bank balance. Also, I hope you're not claiming that the reference range is vastly different for certain people.
Unless one is diabetic or an athlete, given basic nutritional knowledge, there is no benefit to a CGM over HbA1c.
The benefits for other people are questionable. But if a CGM gets them to be more mindful of what they're ingesting then that seems like a positive.
If you have T1d, you've been able to get the prescription-variant of this product for years with insurance, so there really is no reason to get this unless you're un-insured.
Luckily, there's xDrip4iOS and xDrip++, not to mention Suggah and others, who will happily do the alarming part for you. Not to mention, that to many of us T1D, the CGM is just a secondary data point for our loop, which has a CGM already built in.
That said, one actually legitimate reason a T1D may be better off with their prescribed device is if Dexcom doesn’t readily replace the OTC versions the way they do for prescriptions.
This happens way more often than I imagine most who are unfamiliar would think. Anecdotal from an internet stranger, but just last night, we had a third G7 in a row fail well before the 10 day timeline. And speaking of insurance..they wouldn’t cover the early refill we tried to get a week ago when we hadn’t yet received replacements from Dexcom.
That said, I’ve heard people quote an insurance price of about $100/mo for a g7 (which is the same as this), and Medicare should cover it outright. I’ve seen companies sells the G7 for ~$200/mo if you don’t have insurance, but without a prescription I’ve never actually gone and bought one so I don’t know if I’m missing something.
> If you have T1d, you've been able to get the prescription-variant of this product for years with insurance, so there really is no reason to get this unless you're un-insured.
is dishonest at face value.
The OOP cost can wildly vary per insurer. As important is whether or not the insurance company covers it when you need it.
Typically insurance only covers 30 days at a time. That means on day 29, insurance will refuse to cover the cost at the pharmacy.
Real world schedules, flukey tech and devices, fluctuating pharmacy inventory, and occasionally needing an endo to confirm that you still aren’t the first person in human history to reverse Type 1 diabetes, etc. make “this was covered by prescription insurance” a flimsy-at-best argument against T1Ds considering this.

Moreover, the product models for diabetics are different.
Or you could say that competition reduces the price ceiling, whereas scale reduces the price floor.
