You may wish to ask your Dr if he will test you for type 1 diabetes, which you may possibly have given your age and how high your sugars were. If it
is type 1
diabetes, you will need to continue taking insulin rather than oral meds.
Please learn as much as you can about diabetes. It is managed through diet, exercise and medications (insulin and/or oral). You will need to monitor your blood sugar frequently to see how your medications are working too.
