A CGM helps you manage blood sugar levels when diagnosed with type 1 or type 2 diabetes and allows you to use fewer finger sticks. It has a sensor placed under the skin to measure your glucose levels throughout the day. It also has a transmitter that sends the data to a wearable device such as a cell phone.

What is a BGM (Blood Glucose Meter)?

Also known as a glucose monitor, a BGM is a portable device that helps you analyze your blood sugar levels by checking your blood sugar concentration. Your blood sugar changes throughout the day, so you must check your blood sugar levels several times a day.
