CGM, or Continuous Glucose Monitoring, is a revolutionary technology that helps individuals track their glucose (blood sugar) levels in real-time, 24/7. Unlike traditional blood sugar monitoring that requires frequent finger pricks, CGMs offer continuous, automatic readings, making diabetes management easier and more effective.
CGM systems are widely used by people with Type 1 and Type 2 diabetes to monitor glucose fluctuations and maintain better control over their health. By providing valuable insights into how food, exercise, stress, and medications affect blood sugar levels, CGMs empower users to make informed decisions about their lifestyle and treatment.
How Does a CGM Work?
CGM consists of three main components:
A. Sensor: A tiny sensor is painlessly inserted under the skin, usually on the arm or abdomen. This sensor continuously measures glucose levels in the interstitial fluid (the fluid surrounding your cells).
B. Transmitter: The sensor is connected to a small wireless transmitter, which sends glucose data to a compatible device.
C. Receiver/Smartphone: The glucose readings are displayed on a receiver, smartphone app, or insulin pump, allowing users to see trends, patterns, and alerts in real time.
Key Benefits of Using a CGM
- Better Blood Sugar Control: Get real-time glucose data to make informed decisions about food, exercise, and insulin.
- Early Alerts & Warnings: Receive alerts for high and low blood sugar levels before they become emergencies.
- Fewer Finger Pricks: While some CGMs may still require calibration, most significantly reduce the need for painful fingerstick tests.
- Improved Diabetes Management: See how diet, activity, stress, and sleep affect blood sugar, allowing for better long-term health.
- Enhanced Safety: CGMs help prevent dangerous hypoglycemia (low blood sugar) and hyperglycemia (high blood sugar) by giving timely warnings.
