Introduction to CGM devices
In a person without diabetes, the body can track the glucose levels in blood and releases insulin naturally in the right amount to keep the body healthy. However in a person with diabetesa monitoring system is required to regularly check the glucose levels.The most common way to monitor the glucose levels in the bodyisthrough the continuous glucose monitoring (CGM) devices.
CGMdevices enablethe patients to monitor their glucose levels 24 hours a day through a sensor that sends the report to an insulin pump or toa phone. CGM devices are not blood glucosemonitoring devices as the sensors of the machine are placed inside the body of the patient but do not come into contact with the bloodstream. However they can warn a patient before the level of glucose in blood reaches hyperglycemic or hypoglycemic.
Market for CGM devices
Due to the increasing cases of diabetes worldwide, the demand for CGM devices is rising. The global market for CGM devices was evaluated at USD 0.4 billion in 2016 and is expected to reach USD 1.01 billion by 2024. The market driving factors for the global demand of CGM devices are- early detection of glucose levels, steady increase in the number of diabeticcases globally, and growing global awareness of the benefits of such devices. It is due to these factors that the global market for CGMS devices is expected to grow at a CAGR of 43.9% for the next 5 years. Though the North American CGM devices market accounts for the highest market value at the present, it is believed that the Asia-Pacific market will rise at the highest CAGR in the upcoming time.
Advantages over other Blood Glucose Monitoring Devices
- CGM devicesemploy a less invasive method for measuring glucose levels in blood.
- Highly accurate in measurements.
- No fear of the sensor detaching from the body or breaking during an activity as the sensor is inherently stable.
- Needs only a sensor to be inserted in the body and after it, the device will work continuously for over a year with only occasional calibration. Other devices need to change the sensor frequently and regular calibrations. It is an automatic 24/7 monitor.
CGM devices can be used by type 1 and type 2 diabetic patients, they can provide correct report on the blood glucose level any time of the day even in the middle of the night. However, they can’t replace traditional monitors. They are needed to be consulted to make sure the device is accurate. Still they would provide the information, the patient needs to decide- how much Insulin he/she should take, an exercise plan, the number meals and the gap between them.
