A CGM Without Diabetes Often Shows Less Than You Think
CGM without diabetes has a blind spot: both leading over-the-counter sensors stop reporting numbers past their limits and show a label instead.
Sameer Patel — Founder & Editor
Sameer Patel is the founder and editor of My Medicine Advisor. He is not a doctor or medical professional — before starting this site he worked in banking, and he now researches and edits health information full-time.
He started My Medicine Advisor to make clear, well-sourced health information freely available to anyone. Every article is researched from recognised authorities such as the WHO, CDC, NIH, and NICE, drafted with the help of AI tools, and edited by hand, with sources linked so readers can check them. The calculators on the site use established, published formulas, each one named so you can look it up yourself.
My Medicine Advisor is currently a one-person operation with no clinical review panel, and the site is open about that. If you're a qualified clinician or researcher interested in reviewing content, Sameer would genuinely like to hear from you via the contact page.
The long term effects of high blood sugar are often silent
High blood sugar damages the body years before you feel it. UKPDS found each 1% drop in average A1C tracked with 37% fewer microvascular complications.
Why alcohol and blood sugar lows often show up hours later
Alcohol and blood sugar move in two directions on a night out: up first from carbs, then down for hours. Published sources disagree on how many.
A clear look at diabetes rates by state and what they leave out
Diabetes rates by state disagree across sources for the same state and year. CDC itself publishes 11.3% crude and 10.1% age-adjusted for 2021. Here's why.
Prediabetes Statistics and How to Check Your Own Numbers
Prediabetes statistics moved this year: CDC's count rose from 97.6 million to 115.2 million US adults. Most pages still cite the older figure.
Severe Low Blood Sugar: When to Call 911
Severe hypoglycemia isn't a number on a meter. NIDDK defines it as a low you can't treat yourself — and says to call 911 right away after glucagon.
Telling critical DKA symptoms from ordinary high blood sugar
DKA symptoms can appear while a meter reads normal. In FDA-reviewed cases on SGLT2 inhibitors, median glucose was 211 mg/dL, not the classic 250-plus.
Blood sugar 300 and what to know before you decide
Blood sugar 300 is an action threshold, not a diagnostic one. CDC now says check ketones at 250, not the 240 most articles still repeat.
Your CGM time in range, made clear from 70% down to 1%
Time in range above 70% is the adult CGM target, but older adults are set at above
50%, and pregnancy uses a lower 63–140 mg/dL band entirely.
Reactive hypoglycemia and how a true low is confirmed
Reactive hypoglycemia can't be confirmed by a home meter — accuracy is poorest at exactly the low readings that matter. Here's what a lab draw shows.
