Type 2 Hi sugar

[Tina1970]

I have type 1 diabetes. My sister has been type 2 for a few years but now put onto insulin.
She’s on humulin M3. Before her main meal her sugars were 8.9. Her meal was fish in breadcrumbs, oven fries and peas. Her sugars at 10pm were 21.6, she had 40 units of insulin before her meal.
I have tried to help, but I’m on a totally different insulin than her, mine I can correct. Can she correct her sugars on this type of insulin.

I don't think so, as she's on a mixture of long and short acting insulin. Though I guess she could try phoning her clinic to ask for advice? But like you, I'm T1 and I'm not sure that insulin is managed in quite the same way for T2s.

The issue here is whether she is still producing her own insulin. T2s are insulin resistant, so they typically over produce insulin until their insulin producing cells start to wear out... Many T2s can come off insulin altogether if they just reduce their carb levels to what their bodies can cope with.... (Really, it's counter productive to inject insulin to a system that is already overloaded with the stuff, but I don't know whether your sister is still over producing insulin.)

Your sister would have to do this carefully, because of her insulin, but is she open to reducing her carbohydrate intake? That meal would be a bit of a disaster for the T2s on here who successfully stay off medication altogether by going low carb....

Has she been actually tested for Type 1? Because type 1 runs in families and type 2 runs in families even more. She could either be type 1 or you could be prone to insulin resistance along with being a type 1.

Your sis is eating a large amount of carbohydrates.... If she cut down on those, provided she till produces her own insulin, there might be hope yet of cutting down on the carbs. But yeah, I would advise making 100% certain it really is T2, not late onset T1, (C-peptide and GAD tests) and being extremely careful lowering carbs when on insulin, as the combination could have her hypo... https://josekalsbeek.blogspot.com/2019/11/the-nutritional-thingy.html might help her?

Thank you. Very helpful. I think she should get in touch with her diabetic nurse.
