Is It Possible To (roughly) Measure The Time In Range Using Finger Prick Monitor Only- Or Is A CGM Needed?

A DiabetesTeam Member asked a question 💭
Annapolis, MD

I've been measuring my post prandial bg after a lot of my meals and am getting unexpected readings (160's -212) several times a week (some times same day). I thought I had this figured out-not sure what to think now. When I told my Endo about some lows during my last checkup, he asked to download my meter-and I never heard back from him about it. I've managed to lose 40 pounds and lower both my A1C and blood pressure over the past year. It must be that I have to lower my daily carb intake from… read more

I stick my finger but I am thinking of getting the Libre if possible.🥰

I don’t think time in range can be measured with finger prick tests. However you can do a weekly average by simply diving the total blood glucose figures by the number of tests you do in a week.

Maybe you should opt for a general checkup.

Diabetes is a syndrome and thus is fiendishly complicated with a myriad of feedback loops that can be long or short in effect.

It might be that you are insulin resistant and need to cut down on foods high on the insulin index. See my latest post on reducing insulin resistance with the insulin index. The videos mentioned there were a real eye opener for me and I will be changing my strategy as I'm also having problems keeping my bgs down despite being on a very low carb diet, average 9g carbs per day at the moment.

Beware of sugar free sweets especially those containing maltitol and/or sucralose. That was my downfall and now I have about one a day as opposed to 10 a day!

Avoid diet sodas and opt for home made drinks made with berries or bought water lightly flavoured with fruit juice although they also have some artificial sweeteners.

I think I'll just drink plain water or drinks that only have stevia or erythritol in them.

So it would seem my problem is that I'm consuming foods that whilst low carb are not insulin friendly in some (and I stress "some") cases. In other words despite my very low carb intake I still am insulin resistant to a significant degree.

It really is a challenge but challenges can also be fun in some ways.

@A DiabetesTeam Member I appreciate the advice, insight and support. While I have lost the 40 pounds and that was enough to lower my blood pressure and improve my A1C, it appears I still need to lose more weight. (no surprise here) I planned to lose another 20 pounds but have struggled with that. It is encouraging to realize that just 10 more pounds will but me in the lower overweight category. I suspect I expected normal bg, too soon and that it will take more weight loss to get better blood glucose function. I've been "tag-teaming" between limiting calories and carbs, because it is hard to do both. Now that cool temps are back in the east coast of US, I think I need to walk daily again-for sure. Thanks again for the support. What are your specific goals for your own bg numbers?
