My insulin resistance has been increasing from weeks 19 to 33. Now in the past two weeks, my insulin needs seem to be decreasing and I'm having a lot of lows. This caused my endo to be concerned about the possibility of placenta deterioration. I'm going for non-stress tests every second day now and our little guy appears to be moving in his usual rhythm.

I was wondering if anyone else experienced less insulin resistance at the end of her pregnancy??? My endo said that it can happen after week 36, but she is concerned that it started already in week 33.

My blood sugars have been awesome recently (never a reading above 140 in the last few weeks), which felt good, but it has been accompanied by more lows. Now we are concerned about the sudden change in my insulin resistance. One of my theories is that in the past few weeks, I was pretty inactive due to bad hip pain. That disappeared last week and I think that I am moving around more now. So perhaps my decreased insulin needs are due to high mobility.

I would be curious to hear anyone else's experiences. Did your insulin needs grow until the end of your pregnancy?

thanks for your reply, kristin.

i'll find out more this week, but it seems that my peri wants to err on the side of caution and is assuming the decreased insulin requirements are due to placenta deterioration. i decreased by 20%, then 10% a few days later, then another 5% today.

both make me nervous -- the idea that it could be placenta deteroration, AND the idea that it could be due to something else - e.g., baby being ready - and inducing prior to 37 weeks!

i am not sure how you all keep so sane during the last weeks!!!!
OK, keep us posted! I did not feel so sane during the last weeks :-) I was also worried about what was best. I wanted to push to go to 40 weeks, but in hind sight, my OB-GYN made the right decision by doing the birth earlier.
Looks like I'll be getting an amnio to check for lung maturity on Friday - if they're mature, I'll be induced at 37 weeks. If not, I will get daily monitoring and then will be induced at 38. My insulin requirements haven't dropped in several days, but the docs are super conservative. My A1cs have been at/below 5.6 this entire pregnancy, so I'm a bit bummed that things are taking this turn at the end (not that one always has to do with the other...). But, eyes on the prize, no!? :)
This sounds reasonable -- though I share the emotion of wanting to wait as long as possible. The prize is WELL worth it :-)

Wishing you ALL the best!!!

I am 37 and 1/2 weeks now and have been having lows for the past week. Already decreased insulin by 5 units each basal morning and night. No highs. Got 42 after lunch today. At 2 bananas and an orange and only went up to 92.

Told my endo, he just said maybe reduced calories / change in hormones.

Read up on Lois Janovich. She says that reducing insulin requirement is normal at about 37 weeks and is due to the energy consumed by the contracting uterus (practicing to deliver). I certainly am having lots of practice contractions so this could make sense.

My obe doesn't seem concerned about the reducing insulin requirements other than to make sure I don't go too low. She is not really expert on diabetes it seems, whcih in a way is good, as she just lets my endo manage that side of things.

Will see her on Monday (at 38 weeks) and I guess we'll be discussing birth plan and whether to induce or not. she did say she would prefer me to deliver soon after 38 weeks. I would like the baby to come in her own time, if all else seems fine.

Yes, decreasing insulin needs are normal after week 36. My endo and OB-GYN were concerned that they started much earlier (but even that seems normal according to the replies that I got here and elsewhere).

Glad that you are doing so well!! Look forward to hearing the news :)
