"Sometimes when I test my glucose levels they aren't what I expect... that's OK, I just use my insulin or a cereal bar to move my level back to where it should be"

With all these different things going on, you are bound to get it a bit wrong sometimes. That's the way life is - the important thing is to control it as well as you can.

What should my blood glucose be?

Diabetes UK currently recommends the following targets:

Everday blood glucose
Before meals    4-7 mmol/L
Two hours after meals    No higher than 10 mmol/L
Long term blood glucose HbA1c*    7.0% or less
