Hello, my mum is a type 2 diabetic, on insulin once a day, her levels ar still on 20, she has lost a stone in the last month from anythinf she s eating making her ill. She s waking up without eating and her levels being 17 when taking insulin they still rise To 20, im verry worried due to her always sleeping and having no energy and also has very blurry vision, I m not sure on what to do because it s been like this for weeks now and am very worried thanks
