What a difficult additional pressure when a diet change is encouraged. A long slow process but changing one thing like reheated potato rather than fresh potato or flour substitutes. Might be all HE needs, if prediabetic? Are you his carer?
I wish more support for families who have hereditary diabetes. Loads of families now. I wish I wasn't the only member in my family. I stand alone.

My mum came as a chaperone for me yesterday. She still doesn't get, its related to my diabetes (inflammation). Well pelvic problem and struggling to walk carnt be helping my heart. She'll never understand.
