It is very important to keep blood glucose level within recommended range. This will help to prevent and/or decrease the risk of developing complications.
Below are some of the targets to aim for:
On waking: Between 5 to 7 mmol/l (90 to 126 mg/dl)
Before meals: Between 5 to 7 mmol/l (90 to 126 mg/dl)
Two hours after meals: Between 5 and 9 mmol/l and not higher (90 to 162 mg/dl)
Before going to bed: Between 7 to 9 mmol/l (126 to 162mg/dl)
Before exercising: Between 5 to 14 mmol/l (90 to 250 mg/dl)
These blood glucose targets need to be altered depending on age and amount of complications. In very elderly, it is best to relax above targets. Similarly, in patients with renal failure or on dialysis, it is best to relax the targets. The aim is to reduce the risk of developing hypoglycemia.
