Managing a middle-aged woman with prediabetes

Annie is a 57-year-old woman who came to Australia 25 years ago from China. She recently moved to your area and needs a GP. She is married to an Australian of British background and has one child, aged 20 years. She was recently told that her brother, who was diagnosed with diabetes last year, already has eye damage and Annie is concerned about her risk of developing diabetes. She has felt more tired recently and wonders whether this is a symptom.
