Hello, I am a type 1 and have been for around 4 years due to pancreas/spleen/gall bladder removal due to a malignant tumour. This is my first post although I have been a member for quite some time. Yesterday and today I walked the dogs around the normal places. I was just over 7.5 and 8.1 on these days. I came back and was approaching 4.6 (the alarm on my libra is set on that). I had one small/medium apple and around one hour later I am registering 16. It is very unusual for me. I take Humalog for my bolus and work on 1:10 ratio. I have very recently been moved to Levimir for my basal and I thought that was going well (only been on that since last week). I take 6 units twice a day (morning and night). I find this large jump quite confusing. I am 75 years old. 12 stone 4 lbs and otherwise quite good physically. Any suggestions would be welcome. Thanks.
