I'm 73, male, fit, insulin controlled diabetic for about 13 years. Got diabetes due to Pancreatitis 20 years ago. Over the last 5 years or so my Humalog daily need has varied quite a bit, but up till about a fortnight ago it was generally between 15 and 20 units a day. Highest ever intake was 34 units, and my lowest 3. My GP (lead in diabetes in my area) has told me that this is due to Pancreatic Insufficiency caused by the Pancreatitis, and I understand that. Meds include Creon. About a fortnight ago, my daily Humalog need suddenly went from 18 to 25 to 45 to 11 to 36. OK at times of increasing need, but when the need suddenly crash dives I get massive hypos before I realise that a huge change has occurred since yesterday. I spoke to my GP about this and he told me that I was "managing it," and that I simply needed to "develop more confidence." 24 hours later, I had a massive hypo 1 hour after breakfast that wiped me out for most of the day. My diet and activity levels have not changed at all. Has anyone else experienced anything like this? Any advice? Cheers. Joe.
