I recently had an unusual health event that resulted in me passing out. My wife, who is a physician, thought it might be hypoglycemia, since i'm at high risk for diabetes. She found a super friendly endocrinologist who put me on a CGM for two weeks. I never hit the hypoglycemia range during those two weeks, so it didn't really explain what my issue... but honestly the data was SUPER interesting. Just observing the va…

definitely, catching the "quantified self" bug is a real thing!

What kinds of food intake/non-intake habits aside from the obvious culprits surprised you?

Long-term they will likely make no changes because human desire, habits and behaviors are rarely unknown to us. The parent comment mentioned feeling tired after consuming something with a lot of sugar, was that really a mystery prior to using CGM? I doubt it. Sure it's interesting to correlate to your perceived wellness (or lack thereof) with a wearable spitting out data but after the novelty of this discovery wears…

there is something powerful about the objective outside-of-self confirmation of something because it eliminates the doubt that can be casted as it all being in ones head. External confirmation is enlightening and motivating.

Not to mention humans 150 years ago who ate plenty of bread and still didn't have the problems we have with obesity and diabetes. Or even 50 years ago...

That could also be because a fair amount of the bread in supermarkets today is closer to confectionary than homemade sourdough.

light bread starts turning into sugar almost instantly in the mouth and stomach. It's only one step removed and saliva can break it down quickly because it has amylase. Sour dough and whole wheat/grain breads tend to break down a bit slower. You can freeze bread overnight and make it a bit more "resistant" to breaking down quickly and I pretty much do this with all my breads along with toasting them a bit for sandwiches. Pasta can similarly have its glycemic index lowered by first making it "cold"

how is having low blood sugar a sign of pre-diabetes? I get frequent bouts of hypoglycemia.

Aside from the fun, how did it go? Find anything surprising or insightful in the process? It sounds like an experiment I’d like to do for the purpose of optimizing my daily habits and establishing a better mental model for how my eating habits impact me throughout the day. But I really dislike needles.

If you want to know more about it you can just read about how diabetics treat different foods. Short version; high GI is fast high blood sugar, lots fat and sugar can results long period of with high blood sugars. It is a CGM more or less what you would expect, insulin is the only hormone that lowers blood sugar, then you have all the stress hormones that raise it like adrenalin, growth hormone and cortisol plus gluc…

I'm asking out of curiosity here: I've always heard that fat doesn't spike your glucose at all and protein only if you a considerable amount of it. So from what you said if you ate a fatty cheeseburger (plated like a steak and without the bread) that your blood sugar will spike? I'm currently doing a Mediterranean style diet during the week and slacking off a bit on the weekends friday evening through Sunday morning. I have done keto in the past though with the readings I've done on it saying that lots of fat, some protein, and just a little bit of carbs should basically keep any glucose spikes very low. I could only handle the keto for a couple months though.

What symptoms would one have to present for an "online prescription mill"/"virtual care provider" to prescribe a CGM? I'm fascinated by this and would love to try it out but I don't want to bother my family doctor with this.

The only symptoms needed are a pulse, the ability to type out a credit card number, and availability for a sham phone call. It's virtually impossible to not get prescribed one from a mill.

How much would a month or two cost me if it was out of pocket? I wouldn't mind doing it for science.

This is just monitoring, not a pump. There is no learning or tuning or dosing. If it’s anything like the Freestyle I wore for a while there’s a self calibration process that takes a couple hours, but that’s per-sensor, and those get changed out every two weeks.

You are correct, I think he was talking about a different device: https://www.fda.gov/news-events/press-announcements/fda-clea...

I will point out the obvious tensions between these legitimate concerns and the usual HN "we demand full unfettered access to all the firmware knobs all the time" groupthink.

> Where is the harm in getting data on how your own body deals with glucose? We have a relatively good indicator of long-term glucose levels: HbA1c blood testing. It's included in a lot of physicals now because it's relatively cheap. It's not 100% sensitive to every possible condition, but it's quite good as a screening mechanism for the general population. CGMs will often give an "estimated HbA1c" value based on sta…

At the age of 45 I had never had an HbA1c test. I found out I had T2 diabetes from getting a CGM as part of a health study I applied for, and seeing my blood glucose was at 22mmol (it should be under 10). I ordered a finger prick test kit from Amazon assuming the GCM was faulty but it wasn’t. After this I went to the doctors who confirmed with an HbA1c and put me on Metformin. It certainly should be part of routine c…

Where are you based? I have it tested annually, but only after moving to USA (from Poland). I don't remember if I had such a test done earlier - I think I might have had it done as a part of screening for whether I'd be allowed to go scuba-diving or something else sports-related.

I don't know why modern days we get so many problems wrong. A -> B, then B -> A => incorrect In a fire, we see firefighters, that doesn't mean firefighters cause fire. In diabetic patients, we see high glucose level. That doesn't mean eating high GI food causes someone to have diabetes. If we look at the Blue Zone, many people eat mostly carb. So carb/high GI food definitely doesn't cause diabetes. Devices like this…

Glycemic index is only sort of useful for people who actually have diabetes, where blood sugar dysregulation makes insulin regulation equally as precarious. For anyone who doesn't have diabetes, GI doesn't really mean anything other than that their insulin may or may not spike in a short period of time related to a food. Glucose spiking, hence insulin spiking, is not something you want, but this also doesn't mean tha…

Every response you have don't relate to my comment! and I believe you have incorrect info in your responses as well.

Thanks for confirming. Normal feedback on health habits is delayed by months/years and hard to trace back to specific actions so your story makes a lot of sense. I might have to get over my dislike of needles :|

It's more akin to a finger prick than a needle. Might still be a bit psychologically challenging but I've done it and it's really not bad at all.

I'm not even diabetic but they always pre-check your blood during blood / plasma donating. I would say it doesn't even register as a pinprick and feels more like the percussive slap of a tiny elastic band.
