I can understand your concern.
first of all, she has to take her prescribed medicines daily and get her sugar checked on a regular basis.
she should be avoiding foods with high glycemic index and also she should restrict her salt intake.
high protein diet and high finer diet is to be taken.
as per exercise, walking for atlas 20 minutes twice a day would be enough for her age.
she should get adequate sun exposure like for upto 20 mins a day with 20 percent of her body exposed.
