I was diagnosed with prediabetes and chronic kidney disease about 18 months ago and so I decided to eat low carb. I lost over 20 pounds/9kg . I'm now BMI 22. My fasting blood glucose remains stubbornly pre-diabetic although my post-prandial blood sugars are now well under control. I have been wearing a CGM for 1 week and I've already learned so much. First, I stay around 110 (6.1mmol/L) all night long. Stable, but slightly high. Does anyone else experience this? Second, when I eat low-carb I stay between 95 (4.1) and 120 (6.7) all day long, with the exception of learning that during exercise I go a bit low (60mg/dL/3.3mmol/L) - before my CGM I never saw these exercise lows. But the biggest surprise (to a frequent finger-sticker like me) is that, when I cheat (I had french fries), I have reactive hypoglycemia!!!! I had NO IDEA. I had french fries Saturday night as a splurge (not even a whole serving). To try and blunt the effect, I had them with cheese and bacon. Nevertheless, within 30 minutes I was up to 160mg/dL (8.9). Then I crashed within the next 30 minutes all the way down to 42mg/dL (2.3). 30 minutes after that, back up to 125mg/dL (5.8). 30 minutes after that, back down to 60mg/dL (3.3). At that point I had a little bit of milk, which stabilized me for the rest of the evening. Slept like **** after that roller coaster, though. Splurging isn't worth it! Here's the other major thing - if not for the CGM, I was completely unaware that my blood glucose was so low. In hindsight, I have had these symptoms SO MANY TIMES over my life: lethargic, poor fine motor control (writing/typing difficult), headache, palpitations, and a floaty feeling. I have always just assumed this meant I was tired and I needed to go to bed. Here's the thing that I'm now wondering about: for years, some nights I wake up nauseated and with diarrhea. I have assumed this is a digestion problem or a blood pressure issue, but I am wondering if any of you have experienced vomiting and diarrhea during a hypoglycemic episode? Now that I'm wearing the CGM, I'll catch it if this happens, but luckily it is not frequent (maybe 1 time/month). Also, I guess I'm just looking for some dietary reassurance. Here are my current meals: B: coffee w/cream, walnuts, eggs if particularly hungry L: high-fat yogurt w/berries D: meat + salad decaf coffee w/cream This is what I eat, Monday through Friday. I try to be more relaxed on the weekends. I'll have something like peanut butter w/banana slices for a dessert. Do you have dietary suggestions or ideas for me moving forward? I would love to keep my blood sugar stable (the diet I have DOES accomplish this, assuming I don't splurge and have french fries!!!), but I also WOULD LOVE to bring my fasting glucose down. My liver seems to be a glucose making machine, keeping my blood glucose slightly elevated 24 hours a day, except on the rare occasion when my pancreas goes into hyperdrive and overwhelms my liver's sugar-making capacity. I'm paranoid that my low-carb diet is just making me MORE intolerant of carbs. Am I making myself worse? Reassurance anyone.....?
