Diabetes is a widespread chronic condition affecting millions worldwide, and India is no exception. With over 77 million diabetics, India is often called the “Diabetes Capital of the World.” Managing diabetes effectively requires constant vigilance, as fluctuations in blood sugar levels can have serious health consequences. Traditional methods of monitoring blood glucose, such as fingerstick tests, offer only sporadic insights into one’s glycemic status.
However, Continuous Glucose Monitoring devices have revolutionized diabetes management, providing real-time data that can help individuals make informed decisions about their diet, medication, and lifestyle.
This comprehensive guide will delve into the world of continuous glucose monitoring, exploring its benefits, how it works, its availability in India, and much more.
What is Continuous Glucose Monitoring?
Continuous Glucose Monitoring, often abbreviated as CGM, is a revolutionary method for tracking blood glucose levels in real-time. Unlike traditional glucose meters that require periodic finger stick tests, continuous glucose monitoring devices provide a continuous stream of data, typically updated every few minutes. This continuous monitoring allows individuals with diabetes to gain deeper insights into their glucose fluctuations, helping them make timely adjustments to their treatment plans.

How Does Continuous Glucose Monitoring Work?
Continuous glucose monitoring devices consist of three main components: a small sensor inserted under the skin, a transmitter communicating with the sensor, and a receiver or smartphone app displaying the glucose data. The sensor measures glucose levels in the interstitial fluid (fluid surrounding cells) rather than in the blood itself. This data is sent wirelessly to the receiver, providing users with a comprehensive view of their glycemic trends.
Continuous Glucose Monitoring (CGM) is a technology that allows individuals with diabetes to track their blood glucose levels in real-time throughout the day and night. Here’s a step-by-step explanation of how CGM works:
Step 1: Sensor Placement
The process begins with the placement of a small, disposable sensor just beneath the user’s skin. This sensor contains a tiny electrode that measures glucose levels in the interstitial fluid, which surrounds the body’s cells. The sensor is typically inserted into the upper arm’s abdominal area or the back.
Step 2: Sensor Calibration
After sensor placement, it’s essential to calibrate the CGM device according to the manufacturer’s instructions. Calibration involves taking a few fingerstick glucose measurements using a traditional blood glucose meter and entering these values into the CGM device. Calibration helps ensure the accuracy of the CGM readings.
Step 3: Glucose Measurement
Once the sensor is in place and calibrated, it begins to continuously measure glucose levels in the interstitial fluid. The sensor detects the glucose concentration in the fluid, and this information is transmitted to the CGM device.
Step 4: Data Transmission
The sensor is connected to a transmitter, which wirelessly communicates the glucose data to a receiver or a compatible smartphone app. Some CGM systems use Bluetooth technology for this purpose, enabling users to view their glucose data conveniently on their smartphones.
Step 5: Data Display and Alerts
The receiver or smartphone app displays the glucose data in real time, typically in the form of a continuous glucose graph or chart. Users can see their current glucose level and track trends over several hours. CGM devices can also provide alerts and alarms for both high (hyperglycemia) and low (hypoglycemia) glucose levels. These alerts are crucial for prompt action to avoid severe blood sugar fluctuations.
Step 6: Data Analysis and Interpretation
Users, along with healthcare professionals, can analyze the CGM data to gain insights into their glucose patterns. They can identify trends related to meals, exercise, medication, and other factors affecting blood sugar. This analysis helps in making informed decisions about insulin dosing, dietary choices, and lifestyle modifications to maintain better glycemic control.
Step 7: Sensor Replacement
CGM sensors typically have a limited lifespan, usually lasting from 7 to 14 days, depending on the brand and model. After this period, the sensor needs to be replaced with a new one to continuously monitor glucose levels.
Step 8: Data Storage
Many CGM systems store historical glucose data, allowing users and healthcare professionals to review trends over an extended period. This historical data can be helpful in assessing the effectiveness of treatment plans and making necessary adjustments.
The Benefits of Continuous Glucose Monitoring
