When I was first diagnosed with Type 1, I always corrected low blood sugars with soda. I never knew how many carbs I was drinking, even if it was just a couple of sips, so I didn't know how high my blood sugar would go. Normally, when I corrected a low I would shoot into the 250-300 range and that range would end up being my "diabetes comfort zone".
After 5 years or so of doing that I purchased a CGM, and about a year later I purchased an insulin pump, to further help my life with diabetes. I learned about all the things people used to correct lows with, such as candy, soda, glucose tabs, whatever they were comfortable with. I was tired of having a comfortable blood sugar range that was way too high because I corrected with soda.
My A1c has usually been between 7.2 and 7.9 for the first 5 years of managing diabetes. I decided I wanted to change the way I corrected lows, so I knew how many carbs I was putting in my body, so I knew how high I would go and be comfortable with it. I started buying Smarties, which have 6 grams of carbs in one roll. I've been using Smarties as a correction for the past 6 months and my current A1c is 6.5.
My A1c is the lowest it's been since the day I was diagnosed. Not just because of the way I correct, but because of the way I use my CGM, insulin pump, AND how I correct lows. Every little thing you do impacts your life with diabetes. Making a lot of small steps and making small changes can have a very big and positive impact on your diabetes.
