My partner was diagnosed with Hashimoto's disease (autoimmune hypothyroidism) two years ago and three months or so ago was diagnosed with Pernicious Anaemia, for which he is receiving IM hydroxycobalamin weekly (doesn't seem to be able to go longer than that without the injection). However he has also been just avoiding a diabetes 2 diagnosis for years and now he can no longer escape this. We are about to limit fats and portions, having reduced to almost zero simple carbohydrates and starches. So we mainly eat meat, some fish, non starchy vegetables, and limited fruit. I have three main questions:
1. Does anyone have an opinion or literature references about diabetes and Hashimotos (and PA and other illnesses in this complex syndrome) distinguishing it as a third type of diabetes perhaps, or describing it as something other than a coincidental late onset diet-related type 2 diabetes?
2. How have other people with at least one of the related illnesses (PA, Hashimotos, Lupus...) dealt with this with regard to diet, exercise, or other approaches? (For instance, I notice that quite a few people use gluten free approach but I didn't notice this being related to any diabetes).
3. Has anyone noticed an improvement in the diabetes (glucose levels in blood or symptoms) after using B12 in the longer term?
I'm just trying to do my best to understand this and help my partner - not wishing to deny the illness or anything.
