My boyfriend didnt have to take any medications for his blood sugar( being diabetic),then a DR. gave him predisone and his blood sugar went to 496,we went to another er & they gave him 8 units of insulin via iv drip.A few hrs after this then went back up to 300 -400 again.This was 2 1/2 wks ago-also ER DR put him on glucophage 500mg bid,which has not helped.his blood sugars are still ranging between 200 to 400.He is eating more then usual also eating foods he doesnt even like-he is just not acting "his usual self",he gets confused.Is this still related to predisone hes 6'1 240 lbs.(the new er we went to after all this started the dr daid was d/t the predisone,also didnt know how long would take for the predisone to get out of his system.Getting him to go to dr's is very hard then after all that occurred made it worse.Could there be another reason for this-his blood sugars still high,even with medication,which is now 1000 mg bid & not helping.Any ideas on this? Ty for any help
