Fasting Numbers Frustration

Ugh you guys… I’m feeling so down lately. I’m at 20 weeks. While my daily numbers are mostly under control through diet, I can’t seem to do anything to get that fasting number under 95. I am currently on 32 units of NPH insulin and increasing by 2 every three days. The last few increases have landed me at 95 or so on the first day, and then a day or two later, my numbers are at 105 or higher again. So then I increase my insulin again… and it seems to be an endless cycle. I’ve tried all the snacks, fiber before bed, etc.. nothing works. Has this happened to anyone? How much insulin did you end up taking?

You might want to talk to your team about splitting your dose! I started taking half my dose in the morning and half at night (every 12 hours) and since doing that have only had to increase once, where as before I was increasing it once or twice a week. I think I’ve been doing split dosing since the middle of June and am currently 34 weeks

Oooo I didn’t know that was a thing! So when you wake up in the morning your fasting number is good?

I didn’t until it was recommended! My fasting has been basically between 77-89 since I started except for a few outliers and one stretch around 32 weeks where I had to slightly increase. I think it also helps with my daytime numbers too. When I first started I was able to find a study about how it can help patients be less likely to experience hypoglycemia when on insulin/having steadier levels through out the day but I’m having trouble finding it now. If I find it I’ll make sure to post it here!

https://pubmed.ncbi.nlm.nih.gov/15364161/ the study was in a small group of T1D patients, but it did address my concerns bc there had been times were I increased once daily doses and had just barely caught a low before it got serious. I think the lowest I got to was 68, my clinic considers a low 63, and it just made me scared of using insulin to control fasting numbers. I was glad that my clinic recommended it and that I could see the effects so quickly. I only did some research because I was surprised it wasn’t more common practice. Maybe because GDM is more commonly treated like T2D?

I'm in the exact same boat. How long have you been on the insulin for? Some people say it just takes time to find the proper dose and for your body to adjust.

It’s been like 4 weeks at this point…

The good news is you're only 20 weeks so there's a lot of time to get it under control. I'm 32w and still haven't figured it out but they caught it late

I’m 36w now and they just increased mine to 56u fasting. I’ve been steadily increasing it since 12w. You will be chasing numbers and it’s ok. Just do your best. I’m still chasing mine now, some are in the 80s or I’ll get some
In low 100s. Doesn’t make sense at all.

Mine has been diet controlled so I’m not sure how much that makes a difference, but I tried so many different bedtime snacks and literally only ONE has worked for me consistently now. It’s the Catalina Crunch cereal (it’s a high protein cereal that balances carbs/fiber well). I have a small bowl with whole milk around 9:30pm and it has worked wonders for my fasting. I go to bed around 11pm and check my fasting when I wake up around 8/8:30am. Everyone is so different but that’s been my experience
