If it's from prediabetes, that is 'hopeful' news because one can do a lot -- and fairly quickly -- to bring the diabetic symptoms under control by Healthier food and Adequate levels of a Variety of physical activity. I say this as an octogenarian who does not have any health issues except those related to some impairment, and cataract, but able to live alone independently, often carrying 20 lbs of groceries thru subway and bus systems thru stairs.

While diabetes.ca and diabetes.org have great info for variety of menus it's mostly plant based and free of any highly processed foods that's the key.

Nature is our ally...it knows we screw up now and then, but unless we remain negligent to symptoms, such as poor sleep, overweight, unfit and stiff body, things can get too bad to reverse.
I hope you get to enjoy the health and vitality u deserve!
