Continuous glucose monitoring in MDI

In continuous glucose monitoring (CGM) the sensor is usually in permanent use and it can be used to replace the self-measurements of blood sugar from fingertip. The user must be aware of the limitations of the sensor and be able to make decisions regarding self-management on the basis of the information.

Assessment of the information gained from a glucose sensor is a good tool for learning solutions to different situations in the daily treatment of diabetes. It enables seeing the effect of different types of food, exercise or stress on the blood sugar. It may also reduce the need to consume extra carbohydrates, for example, before going to bed, driving or exercising.

Glucose sensor enables prediction of too low blood sugar levels and better assessment of too hight blood sugar levels and their treatment. Most sensor equipment can be set to give an alarm for an individual blood sugar level that is too high or too low compared to the target level. Sensors can also be used together with an insulinpump.

The benefits of sensor are increased if information about the insulin doses, carbohydrates and exercise are also periodically entered in the device. It pays off to periodically do this kind of intensive monitoring for one's own benefit. Intensive monitoring is also highly useful before a planned appointment with a nurse or a doctor. It makes it easier to implement self-management and make decisions regarding the care.

The use of a glucose sensor has been shown to improve glycemic balance and reduce hypoglycemia. When utilized correctly, a glucose sensor facilitates the monitoring of blood sugar balance and the management of self-care, as well as adds flexibility and safety to everyday life. This often increases freedom, helps with endurance, and creates conditions for a better quality of life.
