It is important for type 1 diabetics to maintain a log of blood sugar levels because a physician uses these records to assess overall health and develop a diabetes care plan, according to the American Diabetes Association. Blood sugar monitoring is often the primary tool physicians use to recommend treatment.
Diabetics should check blood sugar levels frequently, especially if they are having difficulty controlling blood glucose levels, taking insulin, experiencing low blood glucose levels or are pregnant, according to the American Diabetes Association.
Blood sugar, or blood glucose, levels can be checked by inserting a test strip into a blood glucose meter and pricking the finger to obtain a drop of blood, according to the American Diabetes Association. The meter displays the current blood sugar level. With some devices, a monitoring system to log levels is built in and can be submitted to a physician electronically. Some patients opt to create a manual log by tracking blood sugar readings several times each day to review with a physician or endocrinologist.
A log of blood sugar readings helps patients assess how food, activity and stress impact their blood sugar, according to the American Diabetes Association. The results or patterns observed may indicate a need for a change in activity or adjustments to a meal plan.
