3hr post prandial

[kel4han]

I know I have asked this before, but ideally you should be in "range" by hour 2 post bolus right? I am continually not in range until hour 3.5. Have started injecting 15min prior to meal, does not help. Would you change your ratio, or inject 30min prior maybe? I cant seem to stop the "spike" from happening.

Hour 1 (I know)
285
Hour 2
220
Hour 3
160
Hour 4
110

I eat balanced, lower carb meals (40-60c), ratio of 1:40

If I lower the ratio, I go low (70's) by hour 3. I cannot seem to rely on snacking. And, yes right now 70 is low for me:rolleyes:

Ideally, a perfect meal bolus will bring you back to target in approximately 4 hours.

What rapid-acting insulin do you bolus with, kel4han? I used to do Humalog, which did not prevent my post-meal spikes at all - I would have similar numbers to what you have right now. Then my doc switched me to Novolog, so I could use their 1/2 unit pen. That helped a bit, my post-meal spikes were not so big (maybe into the 200s). I found that I could not correct those big spikes at the 2-hr mark, because if I did, I would go hypo later on. And like you, if I increased my bolus to prevent the huge spike, I'd be low later on too. I thought that it just took my body a longer time to come back to normal. Not ideal, but I lived with it. Then I tried Apidra, and this stuff has been amazing for me. My 2-hr post-meal readings are typically 150 or less and I don't drop low later on (4-6 hrs later) because it has a short tail. It's amazing how differently all these rapid-acting insulins work inside us.

I have read 3 to 3.5 hours of testing after an insulin like Humalog or Novolog is the ideal number and should be what you were before you took it or close to it if it is not your ratio is off......if your taking extra for a correction then I don't know but learning with this I realised the 70 is not a bad hypo it is more psychological cause your body is probably not used to the hypo's or lower bg's....I have realized that if my basal is off like it is too much then the humalog works a lot faster if the basal is too little than it takes forever to take affect and if it is actually just right it can take up to 2 hrs for the correction to take affect. Learning all this my advice is to make sure your basal insulin is correct first if it is not then the fast acting will not work as correctly as it is supposed too. Also sometimes when we take a correction, we could still actually have a rising bg so it kind of stops it in it's tracks, and sometimes when we take a correction the insulin is already taking too long to work and when we have shot the correction in the other insulin we have took has already started to take affect, it is a mind boggling thing to figure out, I usually finally have understood when to take a correction sometimes I won't after 2 hrs unless it was a food that I have kind of had to guess.....You'll get it but the advice above about Apidra is some good advice because it doesn't have a tail end..........so it is easier to figure out.....

Is Apidra an insulin? I am on Novolog. No basal, so I know that is not the problem. I drop about 60-100 points at night on my own, honeymooning so I am not taking the Levemir anymore. I guess I will just have to take the three hour post prandial and be happy with that.

... No basal, so I know that is not the problem. ...


Just a theory, but I'd bet money that this is the problem, not that you need basals yet. My wild guess is you need to bolus more and basal less. Your food intake triggers natural release which brings you back down. I think that when your honeymoon is over and you start basaling, you'll get these numbers better.
