The Factors of BGL: Insulin Calculation Factors


I was only taught the basics when diagnosed over 20 years ago.
Correct 15 minutes before you eat and you’ll be sweet!
I kept wondering why my levels consistently fluctuated. I felt like I never had control and instead my failing body controlled me – it didn’t seem fair.

Over time, I was taught some other factors from my endocrinologist when current problems required education. In no way was there any invitation to learn about the missing pieces through my teen and young adult years.

It was social media and diabetic influencers that introduced me to the vast cofactors of correction.
