Diabetes Log Books


It's easier to see your patterns when you write them down.

Once you know your blood sugar patterns, you'll know when you're on target or, conversely, why you're not.

The importance of recording your blood glucose

Log books and data collection are a crucial part of keeping your diabetes under control. When you write down the number it is easier to see your blood sugar patterns and know when you are on target or, conversely, why you are not on target. For most people, trying to remember multiple blood sugar numbers and what was happening at the same time as the blood sugar check is difficult and often inaccurate.

Depending upon your type of treatment you may need to check you blood sugar once every few days or multiple times a day. If you are treated with diet alone, and your blood sugar is under control, you only may need to check every few days. In contrast, if your blood sugar is not well controlled and you are starting medications or taking insulin or pills that increase you insulin levels you should check multiple times a day. When taking insulin, you also need to record your insulin dose, and usually your food and carbohydrate intake and activity level. Ask you doctor for blood sugar monitoring and log book recommendations that are specific for you.

There are three ways people commonly fill out the log books. Each method is listed below.

Simple Method

The simple log tracks your blood sugar at various times on different days. This is suitable when your treatment doesn’t change or put you at risk of having a low blood sugar.

Comprehensive Method

A more comprehensive log includes the blood sugar levels at various times on different days, and includes notations about exercise, food (carbohydrates) and medication doses. Use this log when you want to understand how your blood sugar is responding to different foods, activities and medication.

  • time of day
  • blood sugar level,
  • amount of carbohydrate or sugar eaten
  • food diary
  • type and dose of medications or insulin
  • type and duration of exercise
  • any other unusual events such as medications or stresses

This intensive log is used when you are taking multiple doses of insulin or using an insulin pump.
