Dexcom G6 Journey – Day 1

I am interested in the Dexcom G6 for wellness. I am not diabetic, but I know that by following my glucose numbers with the various activities and variety of foods that I eat, knowing my blood sugars will ultimately help me guide my lifestyle choices. So the biggest news on my diet front is that I am now wearing a 24-hour continuous glucose monitor (CGM) called the Dexcom G6. The Dexcom G6 is a plug-and-play, meaning that you plug it into your body, pair the transmitter and you have continuous glucose readings fort the life of the sensor which is about 10 days. This not an inexpensive endeavor, but I feel the investment is well worth the price.

CGM is a game-changer and hopefully you will gain some insights by my glucose levels and daily activities associated with those numbers. This is a device that everyone, not just diabetics, can benefit. And with more than 90 million diabetics and many on the fringe of diabetes, a CGM could make an impact on those numbers.

The first day I had the CGM on, I was amazed that my blood sugar levels were in the 50’s the entire night. Because the low warning level is set a minimum of 60mg/dL, the low blood glucose warning sounded all night long, forcing me to put the phone in another room. I have been on a low carbohydrate diet for many years now, and I knew that I had low blood sugars from my fasting experiments, but it was nice to see some empirical evidence. Just about everyone of us falls into some level of ketosis while sleeping, and the CGM certainly verified this in my case. So far, my glucose measurements have averaged about 82 mg/dL. By keeping my average glucose levels low, I can reasonably assume that my area under the curve (AUC) is low.

Below is a printout of the last 3 days. The average glucose is around 80mg/dL which computes to a HgA1C of about 4.0, which is the way it should be computed, and not from a single lab test that you get from Labcorp. HgA1C has is a benchmark, though somewhat inaccurate since it is very dependent on the life of your red blood cells, which can be 90-120 days or even longer in some individuals. If you have blood cells that last 120 days and beyond, this will artificially raise the HgA1C. Likewise, if you have ever looked at your CBC on your lab sheet, a value called MCV (mean corpuscular volume) reflects the size of your red blood cells. Large RBC’s reflect a falsely lower average blood glucose. Many insurance companies use HgA1C values to factor in the cost of your life insurance in case you did not know.

In order to see how my glucose levels would be affected by my daily routines, I was interested to see how my glucose levels would be affected by my Chinese Adpatogenic herbs called Tianchi. I use Tianchi most mornings before I take a coffee. I was amazed that the Tianchi had no effect on my glucose levels. Next was my coffee. I usually have a coffee with heavy cream, cocoa, and a bit of MCT oil in the mornings whipped with my electric stirring device. This raised my glucose by about 10 points to the 74. I was not surprised since coffee and heavy cream both raise blood glucose a bit. Here is a video about how I use Tianchi.

Breakfast was the next one experiment. I had some leftover meat and eggs over easy. This increased my glucose levels to about 85 mg/dL.

I wanted to see how the G6 would hold up to intense exercise, so I went motocross riding at my local track. The Dexcom G6 held up just fine with all of the jumping and jarring. And predictably, my blood glucose raised into the 100’s, topping out at 110. Usually blood glucose increases with exercise as your body is breaking down muscle glycogen when we exercise, especially high intensity exercise such as motocross.

Later in the afternoon, I had a snack of Epic liver bites and some pistachios, and my blood sugar stayed in the 80’s.

Next was the ultimate test. Dinner. We went to a restaurant that specializes in local produce and nothing is processed. I had an Elk – beef dish with vegetables and some red wine. Expecting that my glucose levels would jump through the roof, I was surprised to see that my blood glucose levels topped out at 95 mg/dL! I had about 2 glasses of wine and at until I was full. Admittedly, I did not take dessert, so my glucose levels would have gone higher had I eaten a proper dessert. During the night, my blood glucose levels stayed in the 50’s and 60’s…

That is it for this day, I will write more about my CGM experiences…
