Blood glucose monitoring is a process used to measure the amount of glucose (sugar) in the blood. This is important for people with diabetes, as it helps them manage their condition and maintain healthy blood sugar levels. Monitoring can be done using a glucometer, a small device that provides quick readings, or continuous glucose monitors (CGMs) that track levels throughout the day. Regular monitoring allows individuals to understand how their diet, exercise, and medications affect their blood sugar. By keeping track of these levels, they can make informed decisions to prevent complications associated with high or low blood sugar, ensuring better overall health.
