Your blood glucose target range

Glucose is always present in the bloodstream, to be used as your body's main source of energy. As a person with diabetes, it is important to carefully manage the amount of glucose in your blood.

Your healthcare provider will help you to decide the blood glucose range that is best for you. Your target range depends on your age, lifestyle, and the state of your health.

Your blood glucose level will fluctuate throughout the day, depending on your activity level and food consumption. Generally, your blood glucose level is lowest before a meal, and peaks one to two hours after eating.

Low blood sugar - also called "hypoglycemia" - occurs when your blood glucose level drops below your target range. High blood sugar - or "hyperglycemia" - occurs when your blood glucose level spikes above your target range.

Inactivity, unhealthy eating habits, and poor adherence to prescribed medication can lead to a consistently high blood glucose level. Over time, high blood glucose can lead to serious health complications.

It is important to get regular physical activity, eat a well-balanced diet, and take medication required by your healthcare provider.

A healthy lifestyle will help you stay within your blood glucose target range, and prevent or delay the complications of diabetes.
