Type 1 diabetes and pregnant..

[Joanneclaire]

Hello

I am 25 weeks pregnant and had the freestyle libre for 3 weeks. I have always had quite tight control and have got it because of hypos due to trying to keep levels lower.

I have had quite a lot of high spikes and was really pleased today to have met targets all day, I have raised my evening Lantus over the last few days as fasting sugars had been a little high. I went to bed with sugar of 7.5, no food for at least an hour before this and nothing since. I woke up around 2 am and thought I would check (as I had a hypo last night at this time!) and blood glucose was 12.8 Any idea why this could be? Thanks in advance! This is really starting to stress me out as I am trying so hard and just want baby to be well.

When do you have your evening bolus and meal? It's possible your blood sugar is still rising as you go to bed, though hopefully the libre will show when the spike occurs.

Also, bear in mind that the libre is not always accurate - might have been worth doing an old fashioned finger prick test when you got the 12.8.

Congrats on the pregnancy. Remember that T1s have been successfully having babies for decades (I'm 57 and my mother was T1 when she had me) and been blissfully ignorant of the spikes you are experiencing because cgms and even glucometers weren't available at the time. And I feel for you on the hypos. I lost hypo awareness during both my T1 pregnancies due to keeping my blood sugars low, and ended up having to have friends watch me when I was alone with my toddler during my second pregnancy, I just wasn't safe on my own. I would have killed to have a cgm then, but this was more than 20 years ago so cgms just weren't available yet.

Have you considered investing in a miaomiao transmitter plus xdrip app so that you can get your libre to generate hypo alarms? (It should also make the device more accurate.)

Good luck.

I have my bolus with evening meal. I did also check with my finger prick monitor and it was similar. Hopefully it was a strange one off! I took 2 units of novorapid and 4. 6 this morning so at least it’s settled. It seems like pregnancy is just making crazy things happen!

Thank you for your reply it is very reassuring I think I’m probably overworrying it I just want her to be here safely.

I have also lost some hypo awareness, I used to feel it if my glucose was around 4 so before I even went hypo but it is getting much lower before I realise, luckily I have still been able to tell though! I’ve not heard of the transmitter but will definitely look into it.

Thank you
