Insulin Sensitivity Factor

Diabetes Forum The Global Diabetes Community Find support, ask questions and share your experiences. Join the community The ISF on my pump was initially setup at 1:3 when I first started on the pump. But last week the nurse wasn't happy with the speed at which the correction boluses were taking effect so did a recalculation of the ISF for me. I'm now finding that the correction boluses are sending me low so am just going to split the difference between the 1:3 I was on before, the 1:2 that she changed me to and set it up as 1:2.5 and see how that goes. They seemed to use an incredibly crude method of figuring it out though, just dividing the average total daily dose of insulin into 100. That doesn't sound a particularly good way of figuring out how sensitive you are to insulin when it is not taking into account other factors, such as how much your eating or exercising. All I can find online about how to figure out the sensitivity is just similar calculations, although using the US units mostly. Can anyone explain the thinking behind such a basic method of figuring it out? Am I missing something obvious in how they come up with the numbers? I might be wrong here Spideog but I don't Continue reading >>

    Insulin Sensitivity Factor Number

    How do I calculate my insulin sensivity factor number? Mine is currently 22, and I strongly believe it needs to be adjusted, and don't know what equation is used to come up with the IFC number. My dr has been on me to get my sugars in better control before my surgery. And I'm totally stressed out trying to and can't figure out why other than my ISF number I use for my humalog that I was first started on might be a bit off. I've had a rough time of it last few weeks. Don't want to sound like a complainer or anything like that, but due to my circumstances it's important to get my sugars in better control.

    my carb ratio is also 10, I agree.. have enough trying to figure up with what to take.. so just giving off last weeks readings of my insulin intake, and carb intake, as well as b/s readings from now on and letting the diabetic center do the calculations for me.. a lot easier.

    actually I'm a type 2, which is why I never understood this calibration on this number and why it doesn't seem to work properly for me.. I got ahold of the diabetic center that orriginally configured my way to take my humalog to refigure it and sure enough I'm off from where I am now. My doctor upped my humalog to 55 units a day and the new number i'm using in figuring my humalog is 18. hopefully I will be having beter results now with the increases in my insulin.. I see the surgeon this week for my surgery but it won't be scheduled till after my heart stress test. So hopefully my numbers will be running a lot better by than. Thanx for all the input & help. this place is awesome. David

  • What Is Insulin Sensitivity Factor

    If you are taking rapid-acting insulin (sometimes called meal or bolus insulin, such as Novorapid, Humalog or Apidra), you educator may talk to you about the option of using an insulin sensitivity factor (ISF, for short) to better control your blood sugars. An ISF tells you how many mmol/l (or ‘blood sugar points’) 1 unit of rapid insulin will lower your blood sugar by. You can use an ISF to calculate how much extra insulin you will need to t ...

  • Insulin Sensitivity Factor Pump

    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 ...

  • Insulin Sensitivity Factor 100 Rule

    Insulin is a hormone that plays an important role in the body's metabolism by controlling blood sugar levels and other processes. It is produced by beta cells in the pancreas and released it into the bloodstream after we eat to enable some body cells, such as muscle, fat, and heart cells, to absorb the sugar from the food we eat. Insulin also helps store glucose in the liver as glycogen when it is not needed, so it can be released when blood suga ...

  • How Do You Calculate Insulin Sensitivity Factor?

    Take control of this hormone to make sure you're staying lean and building only muscle. Here's how. Insulin is very anabolic. It's a hormone responsible for carb and amino acid delivery to the muscles for recovery and growth. So you need insulin, but you need to control it. Insulin sensitivity seems to be the most important factor dictating how the body will handle carbs. Chronic elevation of insulin can increase the rate of transport of fats and ...
