Diabetic, fusion surgery & more, this is all new to me.?

I can only tell you that 149 is high. The target numbers vary from person to person but they usually say the highest it should be is 120. You don't have particularly severe hyperglycemia (high blood sugar). I believe. Be careful with what you eat no more carbs, no more soda juice or sugar. I was an EMT and went to Medical Assistant courses however I don't remember the signs and syptoms of hyperglycemia. I know that with hypoglycemia (low blood sugar) are shakyness, dizzyness, and a feeling of being very hungry but not wanting any food I don't remember the others as these are the only 3 I get.
