Sorry this is long winded. I have a type 1 late teen Daughter who was dignosed 13 years ago. For the 1st 6 years she was what the hospital called a "poster child" the insulin she was on ( mixtard 30) was withdrawn within 6 weeks of using the new insulin she suffered her 1st fit and it has progressively got worse, even been in a coma. she has tried nearly all available insulin & I mean tried. she has spent the last 7 years constently hypoing even when on very little insulin & sometimes no insulin even while in hospital. Everything is checked & double checked. All she keeps getting off her Doctors is they don't know !! which does not help. I have had to watch her going from somone who was becoming independent & confident to manage every aspect of her treatment. To somone who is constently trying to gain control. She goes to all her appointments, she follows what they ask her to do to the letter, she is keeping food diary's, she is weighing everything just to make sure she is not over or under estimating her carbs. nothing is working. what can be ruled out is she is definitely type 1, not making her own insulin, does not give herself too much insulin, All her medication is stored properly & she has an excellent diet. I think the problem lies in the way her body breaks down the newer insulins eg an ingredient. I am open to suggestions. I just want her to get her life back.
