Why are my glucose test high ? Continued .

Today is a continuation  of the post from 12/16/12

My suggestion is that this person talk with his / her physician about the  possible use of metformin with glipizide. This combination may be effective in correcting blood sugars but the glipizide  does increase hypoglycemia risk. The risk is the highest in late afternoon and the early morning hours , 2 to 3 AM.

Glucophage combinations with almost no risk of hypoglycemia
There are other combinations with metformin that may be more effective without the risk of hypoglycemia.
    Metformin plus a DPP-4 inhibitor ( Januvia , Onglyza or Tradjenta )
    Metformin plus a GLP agonist such as Byetta, victroza or once weekly Bydureon

I have attached previous post that may improve your understanding of glucophage, DPP-4 inhibitors, GLP-1 agonist , sulfonylureas and lizard spit.
