Blood Glucose Differences Between Left Arm and Right Arm Using a Continuous Glucose Monitor

Status unconfirmed · Not applicable

Conditions studied: Diabetes

In brief

Interest in continuous glucose monitors (CGMs) is growing for use in evaluating real time glucose levels and in detecting extreme high and low values. A CGM is a small device primarily placed on the patient's upper arm or abdomen to measure glucose at frequent time intervals. While the accuracy of these devices is researched extensively, there are no large-scale studies evaluating the differences in the right and left arm in terms of device placement. In addition, intermittent fasting has gained popularity due to potential health benefits including reductions in weight, cholesterol, and blood glucose. However, there remains a shortage of studies researching the effect of short-term intermittent fasting on body fat. The purpose of this study is to see if there is a difference between glucose levels in the right arm and left arm and to examine if short-term intermittent fasting may impact an individual's body fat percentage.
