Q: What is CGM? A: CGM stands for Continuous Glucose Monitoring. It is a system that tracks glucose levels in real-time throughout the day and night, providing users with continuous data on their blood sugar levels.

Q: How does CGM work? A: CGM systems consist of a small sensor that is inserted under the skin, typically on the abdomen, and measures glucose levels in the interstitial fluid. The sensor is connected to a transmitter that wirelessly sends the data to a receiver or smartphone app, where the user can monitor their glucose levels in real-time.

Q: What are the benefits of using CGM? A: CGM offers several benefits, including:

  1. Real-time glucose monitoring: CGM provides continuous updates on glucose levels, allowing users to detect patterns and trends, and make informed decisions about their diabetes management.

  2. Hypoglycemia and hyperglycemia alerts: CGM systems can alert users when their glucose levels are too high or too low, helping them take immediate action to avoid complications.

  3. Reduced fingerstick testing: CGM reduces the need for frequent fingerstick blood glucose testing, as it provides continuous glucose readings throughout the day.

  4. Insight into lifestyle impact: CGM data can reveal how diet, exercise, medication, and other factors affect glucose levels, allowing users to make more targeted adjustments to their diabetes management plan.

Q: Is CGM accurate? A: CGM systems have improved significantly in accuracy over the years. However, it's important to note that CGM readings may still differ slightly from traditional fingerstick blood glucose readings. Calibration and regular sensor replacement are crucial for maintaining accuracy.

Q: Can CGM be used by people with type 2 diabetes? A: Yes, CGM is not limited to people with type 1 diabetes. It can also be beneficial for people with type 2 diabetes who are using insulin or other diabetes medications.

Q: How long can CGM sensors be worn? A: The wear time for CGM sensors varies depending on the specific system and manufacturer. Some sensors may need to be replaced every 7 to 14 days, while others can be worn for up to 10 days or more. It's important to follow the manufacturer's instructions for sensor wear and replacement.

Q: Can CGM be used during exercise and other physical activities? A: Yes, CGM can be used during exercise and other physical activities. In fact, it can provide valuable information about how different activities impact glucose levels, helping users make appropriate adjustments to their diabetes management plan.

Q: Is CGM covered by insurance? A: Coverage for CGM varies depending on the country, insurance provider, and individual policy. In many cases, CGM is covered for people with type 1 diabetes, while coverage for type 2 diabetes may vary. It's best to check with your insurance provider to determine coverage and reimbursement options.

It's important to consult with a healthcare professional for personalized advice and guidance regarding CGM and diabetes management.
