r/ContinuousGlucoseCGM

I am writing to note a recent variance between my Dexcom G7 Continuous Glucose Monitor (CGM) and my Contour blood glucose meter.

Earlier today, my Dexcom G7 app indicated a reading of 240 mg/dL. Because this felt high, I immediately performed a finger-stick test using my Contour meter, which read 190 mg/dL. To ensure accuracy, I retested immediately with the Contour meter, and it confirmed a second reading of 190 mg/dL.

There is a consistent 50 mg/dL variance between the interstitial fluid reading (CGM) and the capillary blood reading (finger-stick). Given this gap, I wanted to confirm which reading I should rely on for my current treatment decisions. Anyone have answers to fix this issue? Or any suggestions?

Do you agree that Medtronic needs to open their CGM data to write to Apple and Android so you have easy access and integration?

Context, this capability is true for every other popular CGM on the market. Libre 3, Dexcom, and Eversense 365.

My dr prescribed me Ozempic and Metformin for diabetes I am hearing so many bad things about both and questions from family and comments like your going to end up with the Ozempic face! Does anyone have experience with these meds?

Besides the obvious "fiber, protein, and fat," what specific foods, drinks, herbs, or supplements materially improved your spikes or consistently lowered the post-spike baseline—especially surprising ones?

Personally, I suspected that these might be helping at various times, but unfortunately, I did not see consistent results with them: psyllium husk, allulose, glycine, mushrooms (especially shiitake), okra, ginger, chestnuts, feta, and cheddar.
