What are normal blood sugar levels before and after eating if I have diabetes?
The food we eat is broken down into glucose (sugar) that enters our bloodstream. Our body uses insulin (a hormone) to transfer the sugar into our cells for energy. If you have diabetes, sugar is unable to enter your cells and it builds up in your blood. High blood sugar levels can cause damage to blood vessels, organs and nerves. Being aware of blood glucose levels helps you be in control of your diabetes.
So, what is the normal range for blood sugar in a person with diabetes?
Blood Sugar Level Chart
It is important to consult your health care professional to determine blood sugar ranges for you, as targets may vary.
| * | A1C (%) | Blood sugar before meals (mmol/L) | Blood sugar 2 hours after eating (mmol/L) |
|---|---|---|---|
| Target for most people with prediabetes | 6.0 to 6.4 | 6.1 to 6.9 | 7.8 to 11.0 |
| Target for most people with diabetes | 7.0 or less | 4.0 to 7.0 | 5.0 to 10.0 (5.0 to 8.0 if A1C targets are not being met) |

If your fasting glucose levels or blood sugar levels after eating are higher than the recommendations, there are several key areas that can be addressed to help manage your diabetes.
Physical activity: Exercise is key in diabetes management. It can help lose weight, lower stress and keep blood sugar levels steady.
Diet: Healthy eating is also a big player in achieving blood sugar targets. Follow a diet rich in whole grains, unsaturated fats, lean protein and vegetables. For more tips on what to eat when monitoring blood sugar and what foods to avoid with diabetes, click here.
