How long are you a diabetic?
HbA1c is more relatable to your diabetes than fbs or ppbs as it gives a 3 month average percentage.
If you have uncontrolled diabetes for more than 5 years get a diabetic profile which can include the following: fbs, ppbs, hba1c, lipid profiling, b12, ECG, renal function tests, urine microalbuminuria, urine analysis.
Opthalmology and Podiatrist consultation may also be required to rule out onset of retinopathy and neuropathy
A good diet plan that is plant based and fitness or yoga regime will help you.
