I’ve come to realize just how differently doctors approach blood sugar management.

Last week in Texas, I was surprised to learn that my sister had already started taking medication to control her blood sugar—even though her HbA1c was only 6.5. For comparison, my HbA1c was 6.6 back in February this year, just slightly higher.

My doctor at the time told me that since I was still in the beginning stage of diabetes, I could manage my glucose through diet and exercise. He didn’t prescribe any medication. But my sister’s doctor, on the other hand, immediately put her on meds—without even asking her to regularly check her blood sugar with fingerstick tests (which I think is a huge mistake).

So I introduced her to CGM: the Continuous Glucose Monitor. In my opinion, this is the only tool that gives you real-time, actionable feedback and effectively trains you to take control of your diet.

That’s what I call a rude awakening by the numbers.

Thanks to the CGM, I’ve completely lost my cravings for carbs, desserts, or deep-fried foods.

Take last night for example—I “bravely” cooked instant noodles (with shrimp, bok choy, enoki mushrooms, and egg) using the notoriously spicy Korean 2x fire noodles I once loved. I ended up eating just over a bowl, but… I didn’t enjoy it at all.

Then came the blood sugar spike.
My CGM shot past 140 and peaked around 150. I immediately hopped on the treadmill for a brisk 15-minute walk while finishing up chores. The glucose reading dropped to 105, but 20–30 minutes after I stopped, it started climbing again. Luckily, the second wave wasn’t too bad, so I just let it ride.

The key point: I didn’t even think the noodles tasted good! That would’ve been unthinkable for me in the past.

One small note from my experience:
CGM numbers tend to read lower than actual blood sugar—and I’m not just talking about the known 15-minute delay due to the CGM measuring glucose in interstitial fluid (not directly in the bloodstream).

In my experience, CGM values are consistently lower than fingerstick results. So I treat them as reference numbers only. When my CGM hits around 135, I assume my real blood glucose is likely over 150—and that’s my cue to start moving immediately.

嗯 還是要講CGM

因為發現每個醫生處理方式不一樣

上週去的德州 了解到我妹妹竟然開始吃控血糖藥 而她的HBA1C只有6.5 相較於我在二月的數字6.6 她比我還少一點

當時我的醫生給我的建議就是因為只是在糖尿病前期 用運動與控制飲食就可以控制血糖 所以他並沒有開藥

但我妹妹的醫生 卻馬上要他吃藥”控制” 但卻沒要他要定時用指尖血糖測試測血糖 (這個很糟糕)

於是 我跟我妹妹介紹CGM continuing glucose monitor 因為這才是真正可以隨時反映血糖的監測系統且警告自己對於食物攝取最有效的方式 =>數字震撼教育!!!

對我來說 數字的震撼教育 讓我完完全全對澱粉甜點油炸完完全全失去了胃口 例如我昨天晚上 “鼓起勇氣”做了炒泡麵 (蝦子 青江菜 金針菇 蛋 在家我認為可能會想吃的韓國兩倍辣火雞面) 炒完後我的確吃了一碗多 但沒覺得好吃 CGM血糖飆超過140 一度到達150

我在做完家事馬上運動15分鐘陽春跑步機(算是快走) 血糖有降下來到105,但停下來後 大約20-30分鐘 又往上跑一波 但第二波沒跑太高 我就沒理它

重點是 我沒覺得泡麵好吃! 這在以前是絕對不可能的!

小小的心得

要注意 CGM數字通常來說比實際血糖要低 我說的不是因為CGM所測的是延遲血糖 (因為它測的是 組織間液中的葡萄糖濃度（interstitial glucose），而不是直接測量血液中的葡萄糖（也就是指尖血糖/毛細血管血糖 capillary blood glucose）所以一班來說有15分鐘血糖差異

但在我的經驗是 CGM數字通常比實際低!!!!! CGM只是一個參考數字 我的作法是如果CGM到達135~ 那表示實際血糖可能已經飆到150以上 要馬上運動
