Blood Sugar Level
Apr 24 2018

Blood Sugar Level

A level of 200 mg/dL (11 mmol/L) or higher often means you have diabetes. Your provider will order a fasting blood glucose, A1C test, or glucose tolerance test, depending on your random blood glucose test result.

Normal and diabetic blood sugar ranges

For the majority of healthy individuals, normal blood sugar levels are as follows:

  • Between 4.0 to 5.4 mmol/L (72 to 99 mg/dL) when fasting 
  • Up to 7.8 mmol/L (140 mg/dL) 2 hours after eating

For people with diabetes, blood sugar level targets are as follows:

  • Before meals: 4 to 7 mmol/L for people with type 1 or type 2 diabetes
  • After meals: under 9 mmol/L for people with type 1 diabetes and under 8.5mmol/L for people with type 2 diabetes
