A fasting Blood Glucose reading of 7.9 mmol/L (Plasma) is a little on the high side, but could be a lot worse, though your recent HbA1c reading of 48.6 is good and shows that in general you have mantained your average B/G levels in the preceeding 120 days very well.
You may well not need to go on any diabetic medications at this moment in time (your Dr will ultimately decide upon this) and he/she might well consider that by your choosing a carefull type of diet together with some modest regular exercise, that is all that is currently required to keep yourType 2 diabetes held at bay.
