I have been asked a lot by my blog’s readers, which are the best wearable blood sugar/glucose monitor devices in the form of A CGM and is there an Apple or Fitbit smart/fitness watch that can monitor blood sugar? and the most common one, Is there a diabetic meter that doesn’t require blood by finger pricking?
I will answer all these questions and more in this article.

Notably, the number of people with diabetes is on an increase mainly due to obesity as well as an inactive lifestyle. Statistically, there were 422 million individuals from all across the world who had diabetes in 2014. Well, it’s alarming.  
More importantly, the process of management of this chronic condition in which blood sugar levels elevate is a complex one. Which is why it often needs a multidisciplinary approach to aid in controlling levels of blood glucose.
To accomplish this purpose, you need to make certain modifications in your lifestyle for instance following a sugar-free diet as well as regular exercising. At the same time, you also require doing its medical management to control your levels of blood glucose.

Is there an accurate diabetic meter that doesn’t require blood by finger pricking? I introduce you to Continuous Glucose Monitoring (CGM) devices:

So, to the question, Is there a diabetic meter that doesn’t require blood by finger pricking?
The answer is yes, and it comes in the form of CGM devices.

For monitoring blood glucose, Continuous Glucose Monitoring (CGM) devices have been the most popular types of wearable devices up until now. Didn’t know about CGM before? Well, a method of tracking levels of glucose 24 hours a day is referred to as Continuous Glucose Monitoring (CGM).

Moreover, the CGM systems measure glucose levels at regular intervals, all through the day as well as at night. More interestingly, it allows you to view your levels of glucose, whenever you want, at a glance.

For seeing trends, you can review the way of changing your glucose levels after a few hours or one day. By viewing real-time glucose levels, you will be able to decide more appropriately the way of balancing your diet, exercise, and medication throughout the day.

Possibly, a Continuous Glucose Monitoring (CGM) system benefits people with type 1 diabetes. Besides, type 2 diabetics using multiple injections of insulin, sulfonylureas or basal insulin may also get benefit from it. Other than that, individuals who are unaware of hypoglycemia or are at hypoglycemic risk may also take advantage of the CGM system.


Pondering Over How Does CGM System Work?

In order to make a CGM system work, you need inserting a tiny sensor beneath your skin, on your arm or abdomen usually. The sensor then performs the measurement of your levels of interstitial glucose. Adding to it, the sensor performs testing of your glucose every few minutes. To a monitor, a transmitter relays the information wirelessly.

Possibly, the monitor is a separate device’s part such as a smartwatch or an insulin pump. Other than this, some CGMs directly send information to a tablet or smartphone as well.

So, Which CGM Device Would Work Best? And How Accurate these devices are?

The CGM devices are very accurate and give a lot of data, in opposition to the traditional blood glucose meter (BGM) which provide information from a single finger prick, the CGM devices will give you a full day data that can be viewed on smart devices like watches, smartphones, and tablets.

Like Dexcom describes it “instead of a snapshot you get a full story”

When it comes to choosing the best CGM device, the accuracy of the reading of glucose levels should be taken into account.  With this respect, the U.S. Food & Drug Administration (FDA) is approving the following CGM devices lately:
