Hypoglycemia and blood glucose monitors -

Devices that combine an insulin pump with a CGM system are also available. See "Patient education: Type 1 diabetes: Insulin treatment Beyond the Basics ". Advantages — There is evidence that people with type 1 diabetes who use a CGM system consistently and reliably rather than blood glucose monitoring [BGM] have modestly better managed blood glucose levels.

The "real-time" CGM devices automatically display your glucose level every five minutes, using numbers, graphics, and arrows so you can easily tell if your level is increasing, decreasing, or stable figure 3.

The receiver recording device can also be set to trigger an alarm if your glucose level gets above or below a preset level, which can be especially helpful for people who cannot feel when they have low blood glucose also known as "impaired awareness of hypoglycemia".

Most CGM systems permit real-time "sharing" of your CGM readings with others eg, family members or caregivers. Some, but not all, of these intermittently scanning CGM devices are able to alert you of low or high glucose readings.

You can download glucose results from the CGM system to your computer, tablet, or smartphone, allowing you to see glucose trends over time. If you take insulin, your health care provider can help you figure out how to use this information to adjust your insulin dose if needed. Drawbacks — CGM systems may show lower glucose values than blood glucose meters, especially when blood glucose levels are rapidly rising.

In addition, the costs associated with CGM are greater than those of traditional glucose meters. Not all continuous glucose meters and supplies are covered by commercial health insurance companies.

Glucose testing — The results of glucose testing with blood glucose monitoring BGM or continuous glucose monitoring CGM tell you how well your diabetes treatments are working.

Glucose results can be affected by different things, including your level of physical activity, what you eat, stress, and medications including insulin, non-insulin injectable medications, and oral diabetes medications. To fully understand what your glucose levels mean, it is important to consider all of these factors.

When keeping track of your results, you should include the time and date, glucose result, and the medication and dose you are taking. Additional notes about what you ate, whether you exercised, and any difficulties with illness or stress can also be helpful but are not generally required every day.

You should review this information regularly with your health care provider to understand what your results mean and whether you need to make any changes to better manage your glucose levels.

Need for urine testing — If you have type 1 diabetes, your health care provider will talk to you about checking your urine for ketones. Ketones are acids that are formed when the body does not have enough insulin to get glucose into the cells, causing the body to break down fat for energy.

Ketones can also develop during illness, if an inadequate amount of glucose is available due to skipped meals or vomiting. Ketoacidosis is a condition that occurs when high levels of ketones are present in the body; it can lead to serious complications such as diabetic coma.

Urine ketone testing is done with a dipstick, available in pharmacies without a prescription. If you have moderate to large ketones, you should call your health care provider immediately to determine the best treatment. You may need to take an additional dose of insulin, or your provider may instruct you to go to the nearest emergency room.

Meters that measure ketone levels in the blood are also available, but due to their cost, urine testing is more widely used.

ADJUSTING TREATMENT. Checking your glucose either with blood glucose monitoring [BGM] or continuous glucose monitoring [CGM] provides useful information and is an important part of managing your diabetes. If you use insulin, your glucose results will help guide you in choosing the appropriate doses from meal to meal.

When you first start treatment for diabetes, you will need to work with your health care provider as you learn to make adjustments in treatment. However, with time and experience, most people learn how to make many of these adjustments on their own. Your health care provider is the best source of information for questions and concerns related to your medical problem.

You may also benefit from going on a diabetes education course if you use Flash Freestyle Libre or CGM. Ask your GP or other diabetes healthcare professional to refer you. If you want to share your experiences about using tech or find out information by asking others using it, go to our forum.

To scan your Freestyle Libre 1 or Freestyle Libre 2 sensors from a smart mobile phone, download the Freestyle LibreLink app from the app store on your phone. You can also share the data from your Freestyle Libre with friends, family or carers via the Libre Linkup app.

They will need to download the LibreLinkUp app and create an account. You can then give them access to your data using your own LibreLink app and their email address. If your sensors, reader or CGM transmitter are faulty, you can send them back to the manufacturer and request replacements.

It may help to send example readings, compared with finger prick checks. You can also report any concerns to the MHRA yellow card scheme. Like all types of tech, looking after it and things like making sure the batteries are charged is important.

If you have any concerns or specific issues with your Freestyle Libre 2, please contact Abbott directly via their Libre2 support pages. Or use the Abbott guides we're sharing below. You may be able to link a smartwatch to a CGM or flash glucose monitor read more further down.

But we would not recommend any of the smartwatches that are intended to be used without a sensor attached to the body. They are sometimes called non-invasive blood glucose smartwatches. Join the discussion on our forum. If you use some devices, like the Freestyle Libre 2, Dexcom One, G6 and G7, you can use a standalone reader instead of a phone to check the readings.

Another option could be to use a smartwatch to check the CGM readings if you have compatible devices and software. Join the chat on smartwatches and devices on the forum.
