Continuous Glucose Monitoring (CGM) sensors are essential tools for managing diabetes. However, users may encounter sensor errors that affect accuracy and performance. Understanding common causes and solutions can help maintain reliable readings.
Common Causes of CGM Sensor Errors
Sensor errors can result from various factors, including improper placement, skin reactions, or technical issues. Identifying the cause is the first step toward fixing the problem.
Placement and Adhesion Issues
Incorrect sensor placement or poor adhesion can lead to errors. Sensors should be placed on clean, dry skin, avoiding areas with scars or irritation. Ensuring the adhesive stays secure helps maintain proper contact with the skin.
Interference and Environmental Factors
Electromagnetic interference from devices like cell phones or other electronics can disrupt sensor signals. Additionally, extreme temperatures or humidity may affect sensor function. Keeping the sensor away from such sources can reduce errors.
Technical and Calibration Issues
Sensor errors may occur if calibration is not performed correctly or if the sensor is damaged. Following manufacturer instructions for calibration and replacing sensors as recommended can prevent inaccuracies.
- Ensure proper placement on clean, dry skin
- Avoid areas with scars or irritation
- Secure the sensor with adhesive patches if needed
- Keep devices away from electromagnetic interference
- Follow calibration instructions carefully
