you should never take more insulin unless you talk to your Dr FIRST. You can go down too low and than what?? I would call my Dr before doing it. I have never heard of ISF(I have been diabetic 20 yrs) so some Dr are not telling people what that is. I test three times a day and that is more than enough for me.

2009-02-25 22:32:00 -0600 Report

Lanore, ISF means Insulin Sensitivity Factor. Most of the time, it's only known when you are on a pump. It's basically figured to know how many units of insulin you get to one carbohydrate.

roshy 2009-02-26 06:58:07 -0600 Report

over here it is known as insulin to CHO ratio!! mine is for 10g or CHO i take one unit of insulin!! well im supposed to !!

Richard157 2009-02-26 08:21:50 -0600 Report

No! ISF is how many points one unit of fast acting insulin will lower your blood sugar. ISF has nothing to do with carbs or carb ratios. If I am 24 points above my desired level and my ISF is 12 then I need 2 units of insulin (Humalog in my case) to bring me down to where I want to be. The ISF is very useful to insulin users. My control would not be so good if I did not use it properly.

Any responses out there?

Richard157 2009-02-24 18:25:15 -0600 Report

I already answered the question but I will say it again. I always take fast acting insulin to bring my highs down to where I want them to be. I will add that if it is late evening or during the night though I take less than I would take during the day when I am awake. That will avoid my going low enough to have a hypo.

roshy 2009-02-22 06:57:31 -0600 Report

i would take extra insulin if my blood sugar was to high.

I also found a small bit of exercise would take them down. Drinking plenty of water also might help!! Just make sure you dont get used to doing this too often my nurse said its a bad habit to be taking extra shots without eating

2009-02-21 22:17:44 -0600 Report

Before I went on the pump, I was on the sliding scale.

Now that I'm on the pump, of course you have the ISF to consider, but also, the pump guards against insulin 'stacking'.

And Debe is right, if you take an extra shot, and you fall asleep, then go low, you MIGHT very well have a bad episode.

If you are dealing with shots, I wouldn't monkey around with giving yourself extra like that. I would definitely talk to my endo.

Please, be careful

Richard157 2009-02-22 08:16:17 -0600 Report

Legs, you are correct! My ISF (insulin sensitivity factor) varies between day and night, In the daytime it is 12 but at night it is 20. If I did not know that and I had a high I wanted to correct before bedtime I might be taking an overdose and have a hypo.

If you have high blood sugar and you know your ISF (the number of points one unit of insulin will lower your blood sugar) then you might take half as much as you would normally take so that you improve your blood sugar kevel but not so much that you might have a hypo.

2009-02-22 19:47:15 -0600 Report

Richard, I had no idea what my ISF was til I started pumping. I'm not sure doctors that don't tell people who don't pump, their ISF. If not, they really should, don't you agree?

Richard157 2009-02-22 20:11:54 -0600 Report

Legs, every diabetic who uses insulin needs to know their ISF but it can be found only by keeping careful records and doing a lot of experimenting, using trial and error. I did that and discovered my ISF varies throughout the day. Knowing that has been very helpful.

I am on a sliding scale. I have also been a diabetic 46 yrs. Still I do what I am told and try the sliding scale, but when I can't get it under control with that I pick up my phone and call the MD. I don't play around with insulin. An extra dose and you go to sleep and forget you took extra and don't say something you go go low and if you are sleeping how would you know? Don't play with insulin…Debe

jsd2005 2009-02-21 09:52:13 -0600 Report

I wouldn't recommend doing this unless you have talked with your physician first. You may have to consider a different type of insulin or simply an adjustment in your current dose.

Many people do adjust their insulin dose based on what their sugars are. This is called a sliding scale insulin regime. Many times, you will see this during acute illness as insulin needs can change so abruptly.

There are different types of insulin as someone else here mentioned and each has their own specific action, onset and peak. It truly is best if you can mange on a daily basis with diet, medication and exercise and to be a consistent as possible.

I understand the rational for the sliding scale with acute illness, but question it's use for maintenance. I'm not saying I'm right. yet, I've mentioned before that I feel there isn't anything such as a borderline diabetic. Either you are or aren't. The sliding scale insulin regime is a reactive measure or treatment and not proactive. Again, with difficult management or acutely variable blood sugars it is a good tool and necessary.

discuss your concerns with your physician and work out a plan together.

That very thing happened to me not too long ago and I found out that my meter was reading the blood test wrong.
Did you check your meter? It may be old or just coded wrong. Call the company the meter is made and they will send you a new meter for free. Look on the back of the meter for the 800 number and call them.
Good luck

I would like to thank all of you for all your great advice. This site is so helpful in so many ways. Or when you are in between Dr. appoint. I am type 2 on Novolin 70/30 by the way. Many thanks to all and I wish you all a great weekend. I did manage to get it under control and checked bs very often and 90 was the lowest it went !!

rbergman 2009-02-20 12:42:22 -0600 Report

In reading responses to your question, I think it important to take into consideration if those of us answering are Type 1 or Type 2 diabetics as well, we have different rules for certain things concerning insulin, Again the best advice is ask your physician or Endo and go by what they feel is best for your personal circumstances as we are all different regardless whether we have the same disease or not.

Richard157 2009-02-20 11:43:32 -0600 Report

I ALWAYS take extra units of fast acting insulin when I go high. I use Humalog and it lasts 4 hours in my body and then it is out of my system. I use Humalog before every meal and snack. If I eat lunch at noon and I see a high, perhaps 170, two hours later then I take extra. How much I take depends on my insulin sensitivity. One unit of Humalog will lower my blood sugar 12 points. That is my insulin sensitivity factor (ISF). Your ISF might be quite different. I try and keeo my blood sugar about 90 (my target). If I had a 170 two hours after lunch then I am 80 points above my target. Since my ISF is 12 I divide 80 by 12 and get 6.7. Then I consider the insulin still in my body from the Humalog I took before lunch. If I took 8 units before lunch there are still 4 of those units left in my body (insulin on board = IOB =4 units). I subtract that from 6.7 so I won't overdose and have a hypo. 6.7 - 4 = 2.7. I take 2.7 units of Humalog to bring my level down to target. I can take tenths of a unit with my pump. If you inject then you can round off a 2.7 to 2 to play it safe.

You would have to know your own personal ISF to use this procedure.

Richard, you are my idol, in reading your post I was very impressed in the grasp you have on your own diabetes. Regardless whether you have had years of practice at it or not, the fact that you are so diligent about your care is a true inspiration!!!


MeiMei 2009-02-20 08:38:37 -0600 Report

I ditto the previous. Talk with your doctor before taking any more insulin. Some don't show results right away and if your blood sugar is not under control you need to consult with your doctor.

i have the same problem cant seem to get lower then 233 kinda weird i been doing the same activity and eatting the same foods as always even got a wii-fit an yes i use it lol but still no lower then 233 even after a pretty hard workout yes with sweat and everything lmao

rbergman 2009-02-20 08:27:38 -0600 Report

I too follow the guidelines prescribed by a doctor as far as taking extra, I however am on Novolin 70/30 and it is one of the slower acting insulins. I do not get a "quick" fix to my numbers with taking extra it takes hours before I see results and I take the extra at bedtime so that my numbers in the AM are lower.
I also agree that you should contact your doctor about your "constant high" before you self medicate.

dj7110 2009-02-20 04:27:52 -0600 Report

I would not adjust your insulin without first talking to your dr. What type of insulin are you on? There 3 general different types.. long acting(aprox 24 hrs) such as Lantus shorter acting such as humulin 70/30.. lasts for aprox 12 hrs and the fast acting such as Humalog wich lasts aprox 4 hrs. I am currently on the lantus at night and humalog with all my meals during the day. My dr allows me to take extra humalog to bring sugars down when its high provideing I haven't a recent shot of humalog within 4 hrs or so, by subtracting 100 from current b/s reading and divideing this number by 22 = amount of units I take. But everyone is different and this is based on my weight and so on. So ask this to your dr. before you do kind of adjustment. As a low can be more serious issue than high sugar.
