Part 2 of 4 parts
Information that is important for
all people with diabetes.
If you are newly diagnosed or an old
hand, please take time to read or reread the instructions that come
with your meter and the instructions in the box with your test
strips. Instructions do change and I am of the habit of trying to
read mine on at least a yearly basis. Every now and then, I learn
something new or find that instructions for the test strips have
changed. Example, it used to say to clean your finger to be used for
testing with an alcohol swab and let air dry. Recently, this
instruction change to wash you hands and thoroughly dry. Even I know
this is better, and would add to wash with warm water and soap and
thoroughly dry. It is important not to handle the test strips with
wet hands as you could cause problems and receive an incorrect
reading.
Learn How to Test Almost Pain Free
At first, pricking you finger to get
blood for your test strip can be intimidating. With practice and
knowing your equipment, this will become almost second nature.
Unless you can prove that testing on the tip of your finger is
painless, learn not to test there. Learn to test on the sides of
your finger. About an eighth of an inch below your fingernail and on
each side and for about three sixteenth of an inch is the best area
for pricking your finger. Also use the area just behind where the
nail extends (area you trim) to about where the nail emerges from
your skin for the boundary front to back within the area in the
previous sentence. The below image shows the appropriate pricking
area.
Some people are able to test like in
the picture below, but not many. There are more nerves in this area
for most people. I know that this area does not work for me.
However, that does mean that you can’t experiment.
Next, examine your lancet device. In
the picture above near the left area near the lancet area and look
for a dial or adjusting slide and select the lightest setting
(usually the lowest number) and start with this. The above shows the
dial area, which is on the reverse side of the lancet device. Then
take a lance from the box and insert it in the correct area for
holding it, then carefully twist off the round-like tip and you are
ready to go. One the above lancet device, just pull of the dial and you will see the insert for the lancet.
If you have not been shown how to do
this, ask a pharmacist, or if you have one, a diabetes educator for
instructions. Then press the top (on most devices) until the device
is cocked. (See the right side of the Softclix picture above.)
Holding the device firmly against the side of one finger, press the
release button (the button to the left of the Softclix name in the
picture). If there is no or very little blood, move the dial or
slide to the next higher number and repeat. There is no need to
change lancets yet. If there is sufficient blood for the test strip,
then this is the setting to use. Repeat the above until you have
sufficient blood. Most of the time nearly enough blood could be
enough if you gently press your finger and move the pressure toward
the area of the blood. This is what we term as milking the finger to
obtain sufficient blood. Do not use a lot of force, but set the
depth of the lancet deeper.
A word of caution, please. Please know
that if you hand write a lot, you may have some calluses on the
finger you use the most for holding the pen, pencil, or other writing
tool. If you want to use this area, you may need to adjust the
lancet depth more and then reset it for the rest of your fingers and
thumbs. Rotate finger sides and fingers for each time you prick for
blood. The strategy for using the sides of the fingers is these
areas contain fewer nerves and the sole and fingertips have many more
nerves.
Now about changing your lancets. You
may have been told to change for each finger prick. This is true and
probably a good habit to get into. However, after using a single
lancet for several months, I have gotten into the habit on only
changing mine about every three months. Some people change weekly,
biweekly, or even monthly. In other words, we don't change lancets
for every use. I do change lancets if I use my lancet device on my wife or
any other person and change it when I use it again on myself. I do
keep alcohol pads around to sanitize the area of the lancet device
that presses against the skin when testing on others. I also adjust
the depth setting, as I don't normally need as deep a setting for
people that do not test. Read
this by Alan Shanley for another viewpoint on painless pricks and then one from
Jan 5 that covers much the same ground as mine.
Do not use alcohol pads to clean the
area that you will prick. Alcohol pads will dry your fingers and
during the winter, they will crack, becoming very painful. It is
better to use warm water and soap to wash your hands and dry
thoroughly. Read
this for more reasons to use water and soap. Also, David Mendosa has a
blog on Health Central about operator error that is worth reading.
Learn and know the why of testing
Yes, learn about testing and the why of
testing. There are many sources for this information. Don't be like
many people and think you are doing the tests for your doctor. This
is a fallacy and needs to stop now. Many, if not most, doctors
outside diabetes offices, never look at the data or blood glucose
reading log. Most are only interested in your A1c. Many diabetes clinics do download the readings from your
meter, print out logs, and review them with you to ask questions and
give you assistance in interpreting them early on. Then they expect
you to know what the readings mean and how to use them.
The best reason for testing is helping
you effectively manage your diabetes. Without testing, how are you
going to be able to know what is happening, what needs to be changed,
and if the change was even the right change? No, you will be in a
fog with no direction and cannot even know what is happening.
Test with a Purpose
One of the best blogs about testing is
this one by Alan Shanley. Although this blog may suggest testing
more often than many people can afford to test, it is still
applicable in learning the why of testing. Once you have read that
blog, I suggest reading
this blog, also by Alan. What I like about
Alan's style is that he can be very insightful and lead to an
understanding. In addition, he is not afraid to say that you need to
find what works for you and not follow what works for him. For some,
following his suggestions will work and for others they will need to
read for understanding and find what works for them. Do not hesitate
to bookmark anything you may want to review later.
Testing is important to know what your
body is doing and what food is doing to your blood glucose levels.
Testing gives you what your blood glucose is at that time.
Therefore, I would encourage you to read this by Jenny Ruhl –
here
and
here – to get some guidance also in testing. You may notice
that the first link is the same information as the first link for
Alan. This is because this is excellent information and important to
know. There is also excellent information on Jenny's site.
No, this is not what the American
Diabetes Association (ADA) preaches. The more you read and learn,
the more likely you may find that the dogma preached by the ADA does
not work for you. The levels they suggest using are in the range
that encourages diabetes to progress and does not prevent
complications from developing. Management of your diabetes is the
goal to prevent or slow the progression of diabetes and prevent the
complications from developing. Yes, it is possible and this should
always be considered a goal of diabetes management. Many of us use
this from William Polonsky, “Diabetes causes nothing! It is the
lack of diabetes management that causes the diabetes complications.”
This means that if you don't manage your diabetes, complications
are quite likely.
Yes, there is a purpose behind testing
your blood glucose. You are doing the testing for your benefit and
to measure your blood glucose to know that at the one or two hour
time after eating that you have achieved your goals. Intensive
testing to find your general time of high blood glucose after eating,
start testing about three fourths of an hour after eating (use first
or last bite, but be consistent), and test every 15 minutes or every
half hour until the three hour mark. If you notice the reading going
down, stop testing. If you have learned from intensive testing that
you reach your high blood glucose level about 90 minutes after
eating, then you will generally desire to test at the 90 minute mark
to make sure that you haven't exceeded your goal. No, I did not use
the one or two hour mark to show you that these can hold true for
some people and other people can vary when they reach their high
point. Many people do reach their high at the one hour mark and some studies show for many people, the the high is reached at about the 78 minute mark.
Know What to Do With the Numbers
Numbers are just numbers unless you
know what they mean. To start with, most normal people without
diabetes the range for blood glucose is between 70 and 120 mg/dl
(milligrams per deciliter - the American measure), or 3.9 to 6.7
mmol/l (millimole per liter – as the rest of the world measures).
This is what the “experts” don't say after the previous
statement. Most normal people without diabetes can have readings
above 100 mg/dl, but they don't stay above 100 very long and are back
below 100 quickly. This can happen after a very carbohydrate heavy
meal and is not the normal happening. They also don't say that
readings of 100 to 125 mg/dl are the range of people that have
prediabetes.
If you have morning fasting readings of
over 120 mg/dl, you need to consider making some food changes the
evening before. Maybe a smaller snack (less grams) before bedtime or
not eating for longer before bedtime other than the snack. If this
does not help, then you need to discuss the dawn phenomenon with your
doctor. This is or can be caused by the normal wake up reaction of
your body and your liver dumping glucose into your blood in
preparation for waking up.
Some people notice that after an
evening meal that their blood glucose levels are elevated over 180
mg/dl. This may mean that the evening meal was too large or
carbohydrate heavy and the number of carbohydrates need to be
reduced. Or, it is possible that an evening walk will help bring
blood glucose numbers back in range. Other people will notice that
after exercise that they are low, (below 70 mg/dl) and need to
consider having as least a 15 gram (or larger) snack before exercising.
By knowing your blood glucose numbers,
this will help you adjust your food intake and possible changes in
your exercise regimen that will help in maintaining lower blood
glucose levels. This in turn will help return a lower A1c reading
and help in your diabetes management.
Know what your blood glucose numbers
are will also help you know if you need to talk to the doctor about
reducing your carbohydrates or if the doctor will need to consider, reducing medications, adding
additional medications, a change in medications, or even the need for
insulin.
