What Are Glucose Monitors and Meters?
In simple terms, glucose monitors will help you to keep a check on your blood sugar levels. If you are a patient with diabetes, you should keep one in your pocket. This will help you to manage your blood-sugar balance pretty well. Generally, for blood tests, you need to visit a laboratory. But blood sugar monitors make this work much easier! So, this way you can manage your food intake without visiting the doctor's place often.
But, the use of this portable machine varies from person to person. The amount of usage of glucose monitors and meters depends on the type of diabetes you are having. Consult your doctor to understand how often you need to use these machines. Frequent usage of these machines has its side effects. So, use within limits!
How to Use These Machines?
Yes, glucose monitors and meters are used to indicate the amount of glucose in your bloodstream. But wait. Do you know to use these portable machines? If not, do not fret. Let me make you understand it's working in a few simple steps.
- Firstly, get yourself a glucose monitor.
- Secondly, these indicators require a drop of your blood. So, it will hurt a little bit. The lancet attached to these monitors lightly pricks the skin. But, the benefits are incomparable to that pain. Yes, do remember to clean up the needle portion with some alcohol.
- Thirdly, this tiny machine will read your blood contents. This is done by the glucometer strips present in the machine. These strips might have some sort of chemicals in them. These assist in giving the numerical reading in no time!
- Keep a bandage handy!
- Now, after knowing these two little steps, you need to know how frequently to use them. The testing requirements depend on two types of diabetes: Type 1 and type 2.
- If you are a person with type 1 diabetes, then it is advised to use this machine at least four times a day. Type 1 diabetes is caused by your system's inability to create the required amount of insulin. The pancreas is unable to produce the needed amount because one is obese. If your body is unable to transport the sugar from your blood to the cells for energy, you are doomed. Using a glucose monitor would help you to keep track of this issue. You will be able to limit the amount of sugar intake this way.
Type 2 diabetes is a condition where the body is unable to utilize the insulin produced by the body. This is yet another problem. Here, the cells are not active enough to accept the insulin that the pancreas produces. Again, this leads to a blood-sugar level rise. But, do not fret. Glucose monitors are there for you.
Precautions to Keep in Mind
A very important thing to follow is precautions while using these monitors and meters. Glucose monitors and meters are very personal. You should not share these. It may lead to infections without giving you a clue! So, always use needles after cleansing them with a little alcohol. It would save you from a variety of serious diseases such as hepatitis or HIV.
How Can You Choose Your Glucose Monitor?
The most crucial step you need to know is about choosing your type of glucose monitor. Now, models are not limited when it comes to glucose monitors and meters. From the cheapest to the costliest, from the basic to the advanced, all options are available in the market. You just need to search for it. You need to understand the model of glucose monitor you are most comfortable with.
Okay. Generally, glucose monitors work by pricking your finger. A test strip is present in the model. After the strip comes in contact with the drop of blood, the monitor depicts the readings! Simple, isn't it? But, times have changed, and these models and evolved. Simplicity has taken a new turn! Now, you will get such models on the market which would not prick your finger to give you blood-glucose readings.
First, let us know certain conditions before selecting the model of glucose monitors and meters:
- Price of the Meter: The cost factor is important to consider while buying yourself a glucose monitor. Please do not spend extensively on glucose monitors. Consider a glucose monitor, which is cheap and effective. One thing to note is that a blood glucose monitor is of two types- self-monitoring glucose monitors and meters and continuous glucose monitors.
The former is pretty cheap and it comes with a lancet and a test strip. Pricking your finger is mandatory over here. The portable machine provides the glucose readings in seconds after the blood comes in contact with the strip. The latter model does not require pricking. These models are meant for taking glucose readings every few seconds. These come with a sensor that is placed under the skin of your tummy. These are a little bit expensive and not recommended for patients with mild diabetes.
So, talk with your doctor and choose according to your requirement.
- Amount of Blood Sample: Now, if you are sensitive to pricking your finger, you do need to consider this factor. Always look for meter glucose monitors and meters that need not more than a microliter of your blood. If you choose this way, then you would be less likely to face the error of insufficient blood. Your test strip won't be wasted in vain this way. And of course, you do not want to waste your test strip; they are pretty costly if you use them frequently.
- Try Using Glucose Monitors That Stores the Maximum Data: Considering glucose monitors and meters that store a lot of data is very helpful. Some monitors have the feature of emailing your data to the doctor, while some have the advantage of tracking date and time. So, selecting a glucose meter having these features assists you greatly. Well, you'll have to spend a little more on these than the ordinary ones.
- Easy to Use: While buying a glucose monitor, you always need to consider this advantage. This is a glucose monitor which has the facility of talking technology! People who are not able to see properly will greatly benefit from this way. A glucose monitor having this particular feature is most suitable for older people.
- Coding in Glucose Monitors: Coding is yet another feature that is ought to be taken into account. Many glucose monitors and meters depend on manual coding. This is often erroneous. This is because you need to calibrate every time you begin to test by inserting new strips. So, a glucose monitor with the facility of automatic coding saves you from this trouble.
- Accuracy and Test Time: These two things are needed to be taken seriously. For accuracy and test time, always consult your doctor. A doctor will be able to provide the best suggestion for a glucose monitor that has these two features.
Two Varieties of Glucose Monitors
It is necessary to know the differences between two sorts of glucose monitors. It would help you to choose the perfect one for yourself. So, why wait? Let us dig into the matter!
Alternative Site Testing (AST)
The most notable advantage is that the samples of blood can be taken from anywhere other than the fingertips. This makes the device less painful. One can take the blood from less sensitive areas such as arms or thighs, etc. Like every device, this too has its drawbacks. The readings are not very accurate in this device. The blood sample from the fingertips provides the best result. This can be achieved through self-monitoring glucose monitors and meters.
Continuous Glucose Monitor(GSM)
The advantage that this device offers is a sensor. You can simply place it under the skin of your stomach. Now the sensor can transmit information to any device, such as a smartphone. It also provides an alert if the glucose level gets too high or low. The greatest disadvantage that this device offers is its high cost. These are very expensive. Also, the sensor is required to be changed after every 7 days. So, this is not recommended unless you suffer from a really serious blood-glucose issue.
Now, we know pretty well about glucose monitors and meters. So, don't you think it is high time to get to know about some of the models of these portable devices? Relax, you have waited enough.
