My mother, aged 79 years, a hyperintensive and a diabetic for several years, recently underwent a CABG surgery for a Triple Vessel Disease on July 13, 2010 and was discharged from hospital on July 21, 2010. She is recovering, yet her blood sugar levels continue to be high and is being administered Novomix 30 ( 20 units before before breakfast and 10 units before lunch). Prior to surgery, she was taking Amaryl 1mg tablets once a day. Is this increased BSR levels following a surgery common enough, are there any implications and what should be the desired course of action?
