Healthcare providers play a crucial role in guiding patients with diabetes towards effective management of their condition. One of the most popular and valuable tools is the continuous glucose monitor (CGM), which provides real-time data on glucose levels. However, before recommending a CGM to patients, it is essential for healthcare provider to have a thorough understanding of multiple factors, including possible interfering substances. These substances, such as certain medications, vitamins or procedures, have the potential to affect CGM accuracy, leading to inaccurate readings and potentially compromising patient care. By recognizing and accounting for these interfering substances, healthcare providers can ensure more accurate and reliable CGM data, resulting in optimal diabetes management for their patients.
