Self-monitoring of blood glucose (SMBG) is an essential tool for people with diabetes, especially those taking insulin or experiencing blood glucose fluctuations. It helps patients understand their dynamic blood glucose profile, allowing them to adjust their dietary intake, physical activity, and insulin doses accordingly.
SMBG provides data on an individual's blood glucose levels at different times of the day, which can be used to schedule meals, physical activity, and medication. For example, if SMBG shows a pattern of high fasting glucose levels, medications targeting liver glucose output may be beneficial. Similarly, postprandial glucose levels indicate the impact of food intake on blood sugar, guiding dietary adjustments.
SMBG is also crucial for insulin-dependent patients, helping them adjust their insulin doses to prevent hypoglycemia and achieve optimal blood glucose targets. This is particularly relevant for those with type 1 diabetes, who may need to measure their blood glucose at least three times daily.
Additionally, SMBG data can be used to establish a longitudinal glucose profile, aiding in day-to-day decision-making and long-term management of diabetes. It is recommended that patients record their SMBG values, along with information about food intake, medication, and exercise, in a logbook. This helps patients reflect on their SMBG results and contemplate necessary adjustments to their lifestyle and nutrition.
The frequency of SMBG testing should be tailored to individual needs, with more frequent testing recommended during illness, periods of low blood sugar, or when adjusting medication doses. While SMBG is a valuable tool, its cost-effectiveness has been questioned, and insurance coverage or affordability of test strips should be considered.
