Hello All,
I have been a type 1 for over 50 years, and have found that different types of insulin, have given me different types of reactions when entering a hypo. Many years ago when i was on animal insulin you would get tingling of the skin around your mouth and tongue, when i went to the first lot of synthetic it was very different, blurred vision was one of the early signs and my wife could see that i was go into hypo,she said that my eyes would get a glassy look to them, if the hypo was a bad one i would start to get the shakes, and skin color would go white, and eventually start slurring my words. In 2010 they put me onto 2 new insulin's and for 4 weeks i could not feel hypos coming on, even in hospital i was 1 on three occasions and knew nothing about , after 4 weeks later they told me to back onto my old insulin, which i did, Recently they have changed my insulin again and i now have a whole new set of sensations to learn, i now sweat profusely, and the bit i do not like is i have developed palpitations and chest pains when entering a hypo state. There are many little signs that we all learn to recognize, and these are very important, the main issue i have found with the newer insulin's is that you do not have the same flexibility with the time as i use to have with the older animal insulin's. I hope you may find my experience helpful in some way.
Best Regards
and Good Health to All
Toby.
