How to Fix a CGM Sensor That's Giving Wildly Inaccurate Readings

When your Continuous Glucose Monitor (CGM) is not providing accurate readings, it can be frustrating and confusing. CGMs are designed to provide real-time glucose data, helping you manage your blood sugar levels effectively. However, technical issues with the sensor can lead to inaccurate readings, which may affect your treatment decisions. In this guide, we'll walk you through the steps to troubleshoot and fix a CGM sensor that's giving wildly inaccurate readings.

Checking Sensor Placement and Glucose Levels

Before diving into the troubleshooting process, ensure that the sensor is properly placed on your skin. Check the sensor's position, making sure it's not twisted or folded, which can affect its accuracy. Also, check your current glucose levels to ensure you're not experiencing any fluctuations that might be impacting the sensor's accuracy.
