This is a complicated question, but the most direct answer is, no.
Diabetes can be managed to the point where diabetic numbers come back down to non-diabetic numbers. For example: blood sugar lower than 100 fasting and A1c around 5.0. However, it is not very common and in most cases it happens with people who are deemed "pre-diabetic". Depending on the diagnosis and prognosis for your diabetes, it is a possibility to alleviate the symptoms of diabetes. However, you would still be highly susceptible to re-entering a diabetic trend so the diabetes is never really gone.
