Hi Joan, Thanks for reaching out to HCM.
I understand your concern and the symptoms do look like your daughter is entering the diabetes
zone. Since i see you have taken the tests required, from a diet point of view, I would suggest her to consume high fibrous foods which will keep the blood sugar levels in control and a Low calorie, low fat and high protein diet. Also, she should drink plenty of water and limit the consumption of simple sugars in the form of sweets, chocolates, tea, etc and also limit the consumption of refined foods such as pizzas, pastas, cakes etc. Care should be taken to include a lot of fruits and vegetables. Whole fruits are always better than Juices as whole fruits add bulk and the fiber will help in keeping the blood sugara in control. Also, since she also has UTI, its advisable to drink a lot of water. Please consult a doctor so that you can also take medication along with a good diet.
