As you learn to manage your diabetes, or the diabetes of someone under your care, administering the proper amount of insulin and its timing is important. I frequently read here about parents who are afraid to sleep at night in fear of a child going too “low”. Often times the low BG reading could have been avoided by more careful use of insulin correction doses.
This article, published by Joslin diabetes Center, offers some wonderful information for avoiding insulin Stacking - a term I use often on this sight. http://blog.joslin.org/2018/04/insulin-stacking-are-you-bolusing-with-your-emotions/?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+JoslinDiabetesCenterBlog+(Joslin+Diabetes+Center+Blog)
My best wishes for your long, active life experience living with TypeOne diabetes.
