Blood sugar monitoring is the process of checking the level of glucose in the blood. This is important for people with conditions like diabetes, as it helps them manage their health. Monitoring can be done using a glucometer, a small device that provides quick readings, or continuous glucose monitors that track levels throughout the day. Regular monitoring helps individuals understand how their diet, exercise, and medications affect their blood sugar levels. By keeping track of these levels, they can make informed decisions to maintain a healthy balance, reducing the risk of complications associated with high or low blood sugar.
