Strange Basal Insulin Question

Hi,

I have been trying low carb for the last 6 months, I have been having 8 units Levemir morning and night, with a trickle of Novorapid for the protein and carbs in fruit/veg.

I have noticed over the last month or so that I have needed to increase my basal insulin to 12/12 from 8/8 with no significant change in exercise (only dif is I no longer go outside on the bike, but use trainer indoors as weather is naff) or eating habits.

I am wondering if this is a hormonal thing, my body doing something expecting winter or something? Has anyone else noticed a need to increase basal in winter? Or is my insulin sensitivity going down? I still drop like a brick from too much Novorapid so I don't think so, unless its Levemir I am no longer sensitive to?

Any ideas? Increasing basal is not an issue, just got me wondering.

I've had similar changes, but in reverse. Reduced BI from 14/14 to 10/10 from July to September, and dinner ratio from 3:1 to 2:1. But recently had to increase BI to 11/11. I had often wondered if weather affected sensitivity. The only other thing I could think of was changing BI sites from thighs to buttocks and using larger injection areas.

So your not alone.
