Hi everyone,
I'm new to the forum so please forgive me if this is in the wrong sub. Had T1 since early teens and I came here looking for some help because I don't really know what to make of this problem. I've spoken to my endocrinologist about it and he seems to not attribute much issue to this saying "just stick with a low carb diet and see if it helps" so if anyone has any experience about it, I'd appreciate it.

Starting in mid-January, my insulin resistance has risen very strangely. I take 18 units of Lantus at night and I'm on a carb ratio for Novorapid. This summer my ratios were 1:10g carbs, in Nov it crept up to 1:7.5g, Dec 1:5g and now it's a hit or miss. It's like my insulin resistance has spiked through the roof and I just don't seem to respond to insulin as well as I used to, if barely at all. I can give 1:5g and still rise in BG as if my ratio was 1:2.5g or even worse. I've resorted to eating very low carbs during the day and loading my calories with fats and proteins to combat this IR spike because I'm really at a loss of what to do or how this was caused. I exercise 5x a week for 1+ hours, an hour of resistance training + 10-20 mins cardio, and my sensitivity increases during this period (as expected) to ~1:10g. But for the rest of the day it drops to nill again. I weigh 187lbs and am at ~14% bodyfat. My a1c at the beginning of 2014 was ~4.9, I was told to increase it because my doctor feared of lows so I increased it up to 5.6 then to 6.5 where he was happier. My Jan a1c was 6.2. I don't want to continue giving absurd amounts of insulin for little effect so like I said, I eat minimal carbs daily.

This also wasn't the first time it has happened to me. ~ 2 years ago, around the same time of the year, the same thing happened when I was in a transition between doctors and had no one to consult so I did a no/low carb diet for almost 2 months before it finally corrected itself. By then I could finally meet with a doctor and he blew it off as a mystery saying "at least it's better now". At that time I supplemented a lot of fats and proteins to maintain ~180lbs, my then weight.

Has anyone experienced this? Can anyone direct me as to a cause of this? None of my habits have changed as to exercise, eating, stress. My weight has been constant since about Sept. It just all appeared out of no where and it's frustrating not know how to correct it with no advice or direction.
 
Thanks for the response jack!
I'll definitely do basal testing. Although I'm aware of most of the foods on that diet page, it appears really informative and I'll be reading through it all soon, thank you. I don't suppose you or anyone could guess a reason to this sudden spike?
 
with LC some people TAG total available glucose.. and bolus for 50% of protein as carbs, it's trial and error what your % would be
 
Andrew, do you bolus for protein at all? Those of us who low carb tend to find that protein requires roughly half the bolus of carbs and often needs it splitting into two doses due to it taking longer to be processed into glucose. If you aren't accounting for it, you will see you bg level increase. It won't spike in the same way but will steadily increase.

As Jack says, always worth a basal test, just to be sure that is correct.

There's a drug called Metformin that is sometimes given to type 1's who are experiencing IR, however there have been members on the forum before who have had similar difficulties to yourself and they changed insulins which helped matters, maybe worth discussing with your Endo,
 
Speaking as a type 2, I clearly can't contribute on insulin dosing.

But I find it very curious that your problem started at around the time your a1c reached 6+

Or have I misread your post?

Looks to me as if you were better on the lower a1cs...

Love your avatar, by the way. :)
