It's to protect people like you (and in fact many on HN) from themselves (and their incompetence). I don't expect you to understand, but self-diagnosing and self-medicating is not safe for you when you don't have the credentials.
A person is no more likely to suffer from "self-diagnosing" the implications of their blood sugar readings than they are from misunderstanding their weight or blood pressure measurements.
Given the massive scam industry promising health and fitness based on CGM readings, I'd say that already has happened. And Abbott and, now, Dexcom, are more than happy to capitalize on the kind of Son of Dunning or Daughter of Kruger who think, that BG readings are the new HRV. 99 bucks/month for no discernible benefit? Buying Dexcom shares now.
"I don't expect you to understand, but self-diagnosing and self-medicating is not safe for you when you don't have the credentials."
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.
The person obviously has a strong conflict of interest, and stands to lose when people empower themselves. You will not convince them if they're not operating in good faith.
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.
