What’s Your Insulin Sensitivity Factor?
Whether you have type 1 or type 2 diabetes, if you’re taking insulin via pump, pen, or syringe, you need to know your “insulin sensitivity factor” or “correction factor.” Without knowing this number, you don’t know how much insulin you need to correct a high blood sugar and risk either going far too low after an injection or simply not going low enough to meet the goal of a healthy blood sugar level. What is an “Insulin Sensitivity Factor”? A ISF (insulin sensitivity factor) is the number of points in your blood sugar by which 1 unit of insulin will reduce your blood sugar. For instance, my ISF is 1:100, which means that if my blood sugar is 200 mg/dL and I want to take a correction dose to bring it down to 125 mg/dL, I would need to take .75 units of insulin. Depending on your level of activity, insulin sensitivity or insulin resistance, your age, your diet, the amount of carbohydrates you consume on a daily basis, and your bodyweight, your ISF could range anywhere from 2 to 200! Children are obviously far more sensitive to insulin than grown adults. Teenagers tend to have higher insulin needs than adults because of growth hormones, and those with type 2 diabetes a Continue reading >>
