Continuous Glucose Monitoring (CGM) Device

CGM or Continuous Glucose Monitoring is a device that can continuously measure blood sugar levels 24 hours a day. It measures the sugar level in the interstitial fluid beneath the skin, which reflects the current blood sugar level. The device sends data to a mobile application in real-time, allowing users to know their current sugar level along with alerts when the sugar level is too low or too high beyond the set threshold. This helps patients manage themselves quickly, and doctors can plan or adjust treatment appropriately.

Continuous Glucose Monitoring (CGM) consists of 3 parts

1. Glucose sensor (Sensor) is a small metal piece inserted under the skin (subcutaneous) to measure sugar levels in the interstitial fluid beneath the skin. It measures every 3 minutes. The sensor can be worn for 14 days before needing replacement.
2. Transmitter receives sugar level data from the sensor and sends signals to the mobile application, allowing patients, doctors, and care teams to access real-time data.
3. Mobile application displays the measured sugar levels and alerts when the sugar level is abnormally high or low. Alert thresholds can be personalized.

Who should use continuous glucose monitoring?

• Type 1 diabetes patients
• Type 2 diabetes patients who receive insulin injections 3 times a day or more
• Diabetes patients with unstable blood sugar levels, very high or very low sugar levels daily
• Diabetes patients who frequently experience low blood sugar, especially those without prior warning symptoms, experiencing dizziness or sudden unconsciousness
• Diabetes patients who cannot control blood sugar levels to target
• Diabetes patients who want to closely monitor blood sugar levels for more effective diabetes management
• Pregnant women with diabetes

Recommendations for CGM users

• Patients should perform fingerstick blood sugar tests 1-2 times daily to calibrate the device correctly.
• Since the device measures sugar levels from interstitial fluid in the subcutaneous fat layer, sugar levels may differ from fingerstick blood sugar by about 10-20%.
• If there is an alert indicating abnormally high or low sugar levels, confirm the result with a fingerstick blood sugar test.
• The device is waterproof, so it does not need to be removed while bathing, exercising, or swimming and can be used during daily activities as usual.
• There may be slight discomfort or pain at the device attachment site.
• If wearing this device, you cannot undergo CT scans or MRI scans.
