CGM Vs simple glucose monitr. Whis is better to use? February 16, 2018

Which CGM for Which Diabetes Patient?
CGM is continuous glucose monitoring.
So, at first before try to take a look at which system is best for different type of diabetics I wish to take a look at, why it is good to use this system?

Both of these products are continuous glucose monitors (CGMs), and both are designated by the US Food and Drug Administration as replacements for finger sticks, which means that people can calculate their insulin dose from the glucose values they obtain from the CGM. With both devices, however, a backup finger stick should be available in case there is some discordance between the clinical setting and the glucose value from the CGM.

Did someone got the humor? I have to carry on that monitor attached to my belly, and when I need to inject insulin, .... I have to stick my finger.  For those who read but do not very well familiar with all staff diabetics face every day I wish to say, reading are wary all the time, and the difference can be up to 20 points even when we take the same miter, the same finger, at the same time. So, when I need to inject insulin, what number of glucose in my blood? No one system will answer to this question. The readings are approximate, never the same.

The Dexcom has been available for the longest period of time. It requires the patient to check the finger-stick blood glucose level twice a day to calibrate the device. The Dexcom then "speaks" to a receiver or to a smartphone and transmits the glucose level to the Tandem t:slim insulin pump and, in the future, to other devices.

Now back to the question, why do I need this device on my body? Also pay attention that it is diabetic who needs to calibrate the device twice a day. What is the reason for this calibration? I use simple way. I take reading, all the time with the same meter. As I said reading is approximate. So, if I take reading with the same meter then there is no gap between meters to take into consideration. After reading I inject insulin, the dose I calculated according to the reading I just got right now, and according to the dose of insulin I inject in daily base.
      That's right. No one can inject dose of insulin according to the reading in this moment. Why? Well, it is simple to understand. I take insulin every day, a few times daily. Because of insulin is very effective readings effected by many shots of insulin I already injected yesterday, and many days before. Today my reading is 55 mg/dl. What dose of insulin I have to inject? I injected 240 units in the morning, and then 240 after dinner. Now I need one shot more. But reading on the meter are normal. According to the meter I do not need insulin at all. With this strategy tomorrow my level of sugar would be under 100 mg/dl.
     So, what really author talking about? Does she know the subject she try to discuss and educated diabetics? I do not think so.

The Dexcom provides alarms and alerts to patients to let them know if their glucose levels are going high, if they are falling fast, and if they reach a certain low level or a certain high level. Specific levels can be programmed into the device by the patient. It gives these alarms to the patient and to people who are following the patient, in real time.

Alarm, what is for? Alarm is very important signal. If we do have any alarm in any system then what we have to do? Take actions.This is what "ALARM"stand for. But there is glucose monitoring system. When alarm must sound? What the number must be alarmed? Good question to ask A. Peters, the author of publication. I bet, she has no one idea what I do try to ask.
Really, what is the number on glucose meter that sugar is 'low' or 'high' that alarm must sound?
     For those who is not very well familiar with diabetes and insulin, or those who just educated by Anne Peters I wish to say, no one of us, diabetic who takes insulin every day, day after day, has so alarming number on glucose meter. This is what insulin stand for. We can have high or low numbers but it is not life threatening. No alarm needed. Diabetic must be very well prepared for any low at any time without alarm, long before very low sugar will strike. Also, if we take insulin, and very well know what dose to inject, sugar never would run fatally low.

The FreeStyle Libre is factory calibrated, so people don't have to calibrate the device.

 This part I did not get at all. How device calibrated on factory?So, I am lost. As I said, the dose of insulin is not so simple to find out. It is snot the proportion between level of sugar in blood and the dose of insulin in units to inject. If this system used as to add-on insulin when sugar get above some number, then what after number dropped? Diabetic must add some carbs? To ride on swings up-and-down? Really, I did not get this point, so I better to move on. At least I am not one who will trust to any factory to manipulate my life.

       Anyone who is on a complicated insulin regimen and is at risk for hypoglycemia will receive an alert or alarm when the blood glucose levels change. I love that feature.

I worry if I would relay on the alarm what about my awareness of high or low sugar? Would this natural alarms work for me? And if I do have those natural alarms, then why do I need factory calibrated alarms? No reason. Well, of cause there is good reason. Both system more costly then simple glucose meter. So, The choice is not for diabetic which system to use, but insurance company, which system they pay.  No one diabetic would pay for this system out of pocket. I simple do not need it. I relay on my trusted meter, and glucose strips. Then there is very convenient to use pen with pre-filled insulin, Lantus Solo Star. In this case no one strip lost, and every one of them cost $1. No insulin lost in useless system. All insulin from pen go to my body system, and do perfect job. 
Comments to the article:

Exactly, she really has no interest in helping diabetics, I've tried to help her many times with no response.

 Nothing more to say. All what is good for A. Peters just how much she got in $$$$$. She will say that Metformin is better then Invocana, and that insulin is not good for Diabetics type 2. All what someone ready to pay, she will say, just the matter of price.
