Diabetes Diary: keep track of your diabetes


The benefits of the Diabetes Diary

Individuals with diabetes who regularly check their blood sugar levels should use a diabetes diary to monitor blood sugar trends and detect patterns in everyday life that may be associated with blood sugar fluctuations. The Diabetes Diary allows you to keep track of factors such as diet and exercise and how this affects your blood sugar by recording your diet, exercise and blood sugar values in the personal diary. In addition, this facilitates the follow-up visits with the diabetes nurse by going through the Diabetes Diary together. After that, it is possible to take measures to correct what causes blood sugar fluctuations.

Check your blood sugar before and after meals (either 1 to 4 hours before or after), this will help you see how well you and your medicine handle different meals. Note the meals that make blood sugar difficult to control and see if blood sugar levels are high during certain parts of the day. Watch how exercise, illness and stress affect your blood sugar levels and dosage doses. For individuals who record blood glucose values over a number of years, it is possible to see seasonal trends. Diabetes diaries are available to download free of charge.

Recommended glucose levels from the National Institute for Clinical Excellence (NICE) for individuals with and without diabetes are listed below.
