The portion of the Sensor that gets inserted under the skin is less than 0.4 millimetre wide (1mm is about the thickness of a few strands of human hair) and it’s inserted only about 5mm under the skin, so most people will never feel the Sensor while it is being worn*.

*In a study conducted by Abbott Diabetes Care, 93.4% of patients surveyed (n=30) did not feel discomfort under the skin while wearing the Sensor.
