What are the SMBG and CGM systems?
Self-Monitoring of Blood Glucose (SMBG) and Continuous Glucose Monitoring (CGM) systems are two methods used to monitor blood sugar levels in people with diabetes.
SMBG involves using a glucose meter to check blood sugar levels at home or on-the-go. This is typically done by pricking the finger with a lancet and placing a small drop of blood on a test strip, which is then inserted into the glucose meter for measurement. SMBG can help individuals with diabetes make informed decisions about diet, physical activity, and medication dosages based on their blood sugar levels.
CGM systems, on the other hand, involve a small sensor that is placed under the skin to continuously measure glucose levels in the interstitial fluid. This sensor is connected to a transmitter that sends the data to a receiver or smartphone app, allowing for real-time monitoring of blood sugar levels and trends. CGM can provide more detailed information about blood sugar patterns and help individuals with diabetes make more informed decisions about their diabetes management.
Both SMBG and CGM systems have their advantages and disadvantages. SMBG is a simpler and more affordable method of monitoring blood sugar levels, but it requires more frequent testing and may not provide a comprehensive view of blood sugar patterns. CGM systems, on the other hand, provide continuous monitoring and can detect trends and patterns in blood sugar levels, but they are more expensive and require a sensor to be inserted under the skin.
In Singapore, both SMBG and CGM systems are widely available and are often used in combination with regular medical check-ups and other diabetes management strategies. The use of SMBG and CGM systems can help individuals with diabetes maintain optimal blood sugar control and prevent complications associated with uncontrolled blood sugar levels.
