2nd pregnancy! - info about insulin resistance compared to 1st pregnancy, or any other advice wanted!

Hi - I recently took a pregnancy test and found out I'm pregnant again with baby#2. I am only now in my 7th week, and already my insulin dosage has doubled! I am taking the same amount of insulin, already at week 7, as I did toward the end of my last pregnancy! I was wondering if this crazy insulin resistance so early is typical for a 2nd pregnancy. Has it happened to others of you out there? Do you think insulin resistance typically peaks a lot earlier the 2nd time around, or if I will continue to become more and more insulin resistant for nearly the entire pregnancy as I did with my 1st pregnancy?

Also, I was wondering if there are any other significant differences in pregnancy#2 versus #1 to watch out for, or any other suggestions, etc.

My first pregnancy was way different from this second one (nearly finished).

First pregnancy I was only just diagnosed. I made do with 70/30 and despite 1 very memorable low did pretty well.

This pregnancy the diabetes has obviously advanced dramatically. Last pregnancy i think my maximum dose of insulin was something like 30 units/day. Now at the end of this pregnancy I am currently up to 100+ units (depending how much carbs I eat). This pregnancy I'm using basal-bolus - no way 70/30 could work given how much things have progressed.

insulin resistance continues to increase during the pregnancy - getting much worse in the 3rd trimester.

My onlya dvice is don't compare with last time. Just treat this as a new situation and do what you need to to control it as well as you can.

Hi SS and congratulations! I am currently 25 weeks with #2 and my insulin resistance seems at about the same level as it did with #1. My A1c is just a little lower now than my first pregnancy. I am approaching my 10 year mark for T1D and my 8th year using a pump.

It'll be interesting to see how my insulin needs re-adjust after birth because the first time around, I was back to 'normal' levels within 5 days and that crash period was really tough- among all of the other stresses going on in those first few days after birth!!!

This time around, doctors have been much more cautious but that is partly due to being 4 years older, having high blood pressure in the last few weeks of my 1st pregnancy, and my water breaking at 35 weeks previously.

Physically my body has changed so much faster than with #1, I've been very surprised.

Best of luck to you throughout this pregnancy!!! Keep us updated!
