I am Type 2 diabetic for the last many years. My age is 68. For the last 6 months my BS level is not changing. It is Fasting 240 and more PPBS above 350 H1bc 7,5. Cholesterol normal. Thyroid normal. Creatinine 1, Urine analysis normal, I am presently taking Lantus Insulin injection 16 units during night with Vobes 0.3 and Glynase 1 each three times Zilenta M in the morning. But sugar level continues to be the same level. Please guide me why it is happening so.
