Yes, we have had members report sudden changes in their insulin resistance.

Are you on any new meds? Prednisone would have this effect.

Stress can also trigger hormones with some increase in BG.

no meds, feeling fine as usual, no stress, no changes at all, not feeling sick at all. I am totally baffled, I just have zero explanation for this. I usually can tell pretty accurately of what my levels are, and my “feeling” coincides with 2 different meters and the dexcom (+/- 10). Wrong readings are probably safely eliminated with that.
Little nervous now with that bolus insulin in larger than usual amounts in my body since 6am. Even though humalog should not be active for more than 4 hours, I don’t want to top of on an already large amount in the last 9 hours.
I switched the ampule and a pod in case of malfunctioning. And will use a new KwikPen for bolus in 3-4 hours.Just in case I had the bad luck of 2 different sources of insulin being bad. If that does not show any difference, I have to come up with Plan C since 4 sources of bad insulin are very unlikely.

Found something. A little far-fetched but we had a very nice summer-like weekend and it could be a delayed “hypertonic dehydration”. I thought I did drink my regular share of water but we were out a bit more then usual. I never knew that dehydration could have such adverse effects like adrenaline and other hormones.

[Causes of insulin resistance in type 1 diabetes].

[Article in German]

Abstract

Insulin resistance is a well-known phenomenon in diabetic patients. Its occurrence in Type 1 (insulin-dependent) diabetes is thought to be due both to metabolic and immunological disturbances. In this context, a key role is attributed to the augmented release of the ‘diabetogenic’ hormones, adrenaline, glucagon, cortisol and growth hormone, as well as to hypertonic dehydration and to the presence of insulin-binding antibodies. In this connection it is noteworthy that among the ‘diabetogenic’ hormones adrenaline exerts the strongest insulin-antagonistic effect and that hypertonic dehydration is associated with impairment of insulin action and of non-insulin-dependent hepatic glucose uptake (in vitro), while hypotonic rehydration reduces the elevated hepatic glucose production in dehydrated Type 1 diabetic patients. By contrast, the generally only slightly elevated serum insulin-binding capacity in insulin-treated diabetics is probably of least importance in the development of insulin resistance, unless excessively high insulin antibody titres prevail.

Keep us posted. I hope it resolves soon.

EH has had a similar issue lately. I didn’t connect it with the weather. I just gave up trying to figure it out. Stubborn high for a few days, used 2x as much insulin as normal and it didn’t bring it down. Not sick. Not overly stressed. No idea.

I would suggest more water (which is now always my suggestion - low or high!) and consider some brisk exercise if possible. Sweeping and vacuuming seem to make EH go low.

Also, he gets canker sores (these are not the same as cold sores, not at all related to oral herpes). Those always jack up his BG and cause stubborn highs. Do you get those?

I think you’re on to something with the dehydration though. I hope it resolved soon!

@john, for us insulin resistance increases a lot with upcoming sickness such a a cold
My son’s basal need typically go up 20-30% a day or two ahead of a cold, then a lot more during sickness (+100% is not uncommon). As MM2 mentioned, stress will also increase our insulin resistance, for instance the week of finals or a large paper due soon.

A few month ago, while traveling, we also saw high insulin resistance from dehydration for over 2 days. We had to drink a ton of water to be rid of it, and worked on it hard afterwards.

Another source, for us, is having an intense run, or some other forms of sport: we can go to 300 after a run if we don’t treat the sport activity just so.

Let us know what you find!

Btw, for us, we tend to wait about 2 hours before stacking insulin.then, when we stack, for dosing we assume that some insulin is still present from the previous injection.

Great ideas with the different uses of insulin sources.

Personally, my insulin resistance fluctuates with hormones and I am very resistant during lack of sleep, stress and upcoming sickness.

Since it sounds like you were outside for the nice summer-like weekend, I would definitely recommend to check yourself (or have your wife check you) for ticks: https://control-mosquitoes.com/how-to-check-for-ticks/

I would imagine fighting off the start of Lyme disease could cause insulin resistance, so it’s just a good idea to make sure that the most common transmitter of it (little tick buggers) aren’t hanging on to you anywhere

My son got a flu a few weeks ago. He usually uses 10 units of insulin. He used 25 units a day for several days. BUT the interesting thing is that the insulin resistance preceded the onset of noticeable illness by a few days. The day he puked was the day his insulin usage started to come down.

So insulin resistance can definitely be caused by illness, and not necessarily when you seem to be sickest.

Have you gained weight? Your mealtime doses sound to me like significant insulin resistance. I gained about 15 pounds but over a period of two years so I didn’t really think it could be an influence. But I have had significant rise in BG in the last few weeks and have been slowly raising my I:C ratio, basals and ISF to get it in control.

For me, more significantly, I am working on lowering my carbs and working on losing the weight because as I Type 1, I need IR like I need a hole in the head. (Which I don’t need!).

I assume you’ve checked your basals to see if there is a pattern of when it rises? I always look to the food and sometimes that isn’t the answer.

To answer a few question:
I am on a fairly low-carb diet, not Keto but low carb and have lost weight and I am still in the process of shedding more pounds. The amount of units has grown over the decades but with eating low-carb it has come down a significant percentage.
I am reasonably sure that I was not ill. Nor were we out in the woods, in regards to ticks and lyme disease but beach.
Stacking of insulin is obviously something to be very careful with. I usually try to keep about 3 hours in between “stacking”.

I am reasonably sure that it was this funky form of dehydration, “hypertonic dehydration” that did not establish it self as normal dehydration would with dark urine or not peeing, headaches and such. I actually felt very normal and was drinking regular water in a normal amount. However that did not do anything to bring down the results but a large bottle of sparkling mineral water with 10mg of Sodium. Tuesday evening and night was finally fine and Wednesday started out good but began to climb late morning again unexplainably. I immediately went for another bottle of Pellegrino, burping my head off, but the results normalized within an ½ hour.
Even after 30 years of being a t-1, it amazes me that I am still learning.

I was T1 for 53 years, and I had gained much weight after changing from animal insulin to synthetic insulin. I was diagnosed with insulin resistance (IR) in 1998. I realize this was not a ‘sudden’ IR, but I wanted to mention it. I used Metformin for 7 or 8 years, and I lost the weight. I stopped the Metformin for almost a year, and I am slowly gaining weight again, 8 pounds this year. I have reduced my carb intake, but I am not losing weight. I may have to start Metformin again.

We all know that with certain types of insulin weight gain is something unavoidable after a certain amount of time. The only thing you can do is continuing the fight against those pounds. Low carb is absolutely a good thing, just give it time. And it actually reduces your insulin need since you are lowering your carbs. And the easiest form of exercise might be walking walking walking even though you don’t see immediate drastic results. But it works in the long run with whatever time we have left.

@John - I have had similar experiences of insulin resistance due to dehydration. Like you mentioned, I thought I was drinking enough despite warmer weather, being outside, etc. In my cases, I couldn’t get enough fluids in orally, and became sick to my stomach. So I ended with an IV. It doesn’t happen a lot, but maybe 4 or 5 times? I’ve had type 1 for 47 years. I never knew this problem had a name or that anyone else had experienced it. Hope you are past it now and feeling well again.

Thank you, feeling pretty good. Results are back in order after rehydrating. Sodium content in the Mineral Water seemed to do the trick. Slight headaches delayed about a 1 ½ days after the incident

You could be developing an illness? I have had my BGs spike like crazy, a first sign of a minor flu shot reaction a couple days before the symptoms hit. If your adrenals are still working, (mine are not)
High BGs can be an early warning of an illness.

After developing Addison’s disease (primary, autoimmune) I last year, I no longer get early warning or dawn phenomena etc.

I get those, especially when I have been chewing the inside of my cheek (a nervous habit). My bgs skyrocket for days as the pain increases, and when the pain starts to abate my bgs drop back to normal.

This happened to me. and I had such a hard time figuring out why… it was like that for a month and a half no matter what I did my sugar would go into the 300’s … What I ended up doing and totally am not endorsing is I did a 5 day water fast and whatever that did brought me back to where I was before… I’ve done a few of them before that time. just for stem cell and flushing reasons so I was familiar with how to do and how my body would react… so do not do without looking into it and getting expert advice.

I’m going through this as well! :frowning: Can’t pinpoint why. My TDD is triple what it normally is, same food intake, exercise level, no illness, no stress increase, etc. Maybe using the pod on my arm, even though I had been using it on my arm before this issue. I’ve noticed in past that absorption can be less effective on my upper, back arm than abdomen (typical area), but from time-to-time I use it anyway. Or, perhaps this is just due to seasonal changes - winter to spring? I might try the fasting as well! I’ve done one 3-day fast in the past and that did indeed help, but it was a couple of years ago.
