The transmitter sends the information, without using wires, to the third part, a software program that is stored on a smartphone, on an insulin pump , or on a separate device called a receiver.

Your doctor may recommend that you use a CGM if you need insulin to manage type 1 diabetes , type 2 diabetes , or another form of diabetes. Talk with your doctor about whether using a CGM could help you manage your diabetes.

Doctors can prescribe CGMs for adults and children. Some models can be used for children as young as 2 years old. Your doctor may suggest using a CGM all the time or only for a few days to help adjust your diabetes care.

All CGMs estimate blood glucose levels, but they store and display the information in different ways. Some CGMs send and display information to your smartphone or receiver automatically. But you will need to scan the CGM with a separate receiver or smartphone every few hours to view and store the data.

A third type of CGM collects data about your blood glucose level for your doctor to download and review later. Doctors provide this type of CGM to check on your diabetes care, and you wear it for a limited time.

For some CGM models, you may need to do a finger-stick test with a standard blood glucose monitor to calibrate the system and make sure the CGM readings are correct. Many CGMs work with apps that have special features, such as.

For safety, it is important to act quickly if a CGM alarm sounds when your glucose level is too low or too high. You should get help or follow your treatment plan to bring your glucose level into a healthy range. The CGM will create an alert and might display a graphic that shows whether your glucose level is rising or dropping—and how quickly—so you can choose the best way to reach your target range.

Over time, keeping your glucose levels in the healthy range can help you stay well and prevent diabetes complications.

The people who benefit the most from a CGM are those who use it every day or nearly every day. Researchers are working to make CGMs more accurate and easier to use.

However, you may experience some issues while using a CGM. For safety, you may sometimes need to compare your CGM glucose readings with a finger-stick test and a standard blood glucose meter.

This could be needed if you doubt the accuracy of your CGM readings, if you are changing your insulin dose, or if your CGM gives a warning alert. You might have to replace parts of your CGM over time.

Disposable CGM sensors should be replaced every 7 to 14 days, depending on the model. Some implantable sensors can last up to days.

You may have to replace the transmitters of some CGMs. You may also need to reconnect the CGM, transmitter, and receiver or smartphone if your CGM is not working correctly. Skin redness or irritation from the sticky patches used to attach the sensor may occur for some people.

A CGM costs more than using a standard glucose meter, but it may be covered by your health insurance. You might be able to get financial help for diabetes care from your health insurance or other resources.

Check with your health insurance plan or Medicare to see if the costs will be covered. An artificial pancreas , also called an automated insulin delivery system AID , mimics how a healthy pancreas controls blood glucose in the body.

A CGM, an insulin pump, and a software program that shares information between the CGM and insulin pump make up the artificial pancreas. The CGM estimates glucose levels and wirelessly sends the information to a software program on a smartphone or insulin pump.

The program calculates how much insulin your body needs, and the insulin pump delivers the insulin when glucose levels rise higher than your target range. On the other hand, if your glucose levels fall lower than your target range, the artificial pancreas can lower or stop the amount of insulin given by the insulin pump.

The artificial pancreas is mainly used to help people with type 1 diabetes keep their glucose levels in their target range. NIDDK has a long-standing commitment to funding research to better understand diabetes and improve the lives of people with the disease.

NIDDK-funded research helped scientists learn that glucose levels in the fluid between cells could be used to estimate blood glucose levels. NIDDK also supported the Diabetes Control and Complications Trial, which showed that people with diabetes could use blood glucose monitors at home to closely control their blood glucose levels and reduce their risk of health problems.

NIDDK conducts and supports clinical trials for many diseases and conditions, including diabetes. Trials look for new ways to prevent, detect, or treat disease and improve quality of life. Clinical trials—and other types of clinical studies —are part of medical research and involve people like you.

CGMs are particularly useful if you often have lows and are unaware of when they happen hypoglycemia unawareness. Even if you have a good handle on your diabetes management, you still may want to consider using a CGM for the convenience and the elimination of finger pricks.

You can get a pump, wear it for a time, decide to stop wearing it, and restart it if you think it will fit better with your treatment—work with your insurance to match whatever works for you.

Pumps are an extra piece of hardware attached to your body. They work by closely mimicking your body's normal release of insulin. If your doctor determines that a pump is a good option for you, it's important to check with your insurance provider before you buy anything.

Most insurance providers cover pumps, but sometimes they may not be covered and pumps can be expensive. In addition to cost, some considerations to consider when it comes to getting a pump are lifestyle, commitment, and safety.

Your insulin pump will be able to integrate your glucose data from the CGM sensor and either suggest changes to insulin dosing or adjust the appropriate amount of background or basal insulin on its own.
