Why does my doctor check my blood sugar level?

It’s a very common question people ask everyday.  Your doctor has many good reasons to know your blood sugar at any point in time.  Firstly, it’s the measurement of glucose in your bloodstream.  Glucose is the energy source for the body and needs to be tightly controlled.  Usually the body has a fantastic system for ensuring your blood sugar remains in normal range.  Remarkable how it all works.  Your doctor or healthcare professional measures  in either mg/dl or mmol/l, depending on the preference of the pathology department.  So to put the size into perspective, the blood sugar machine measures glucose levels 1/3000th of the size of a grain of sugar.  The sample is taken with a tiny drop of blood to calculate your entire body’s glucose level.  So the numbers are very small and thats why you need to accurately measure your blood sugar level as demonstrated in our video on “How to take a blood sugar”.

What is so important about measuring my blood sugar level?

The glucose in your blood has vital importance in keeping all your body functions working properly.  Regulation and function of most body systems depends on the supply of glucose.  What happens when the blood sugar system goes out of control example with diabetes?  Glucose either drops very low causing drowsiness, irritability, confusion and in very extreme cases, unconsciousness and death.  On the other side, high glucose levels depending how high, cause your blood to become thick like honey.

Blood vessels under the extra strain eventually give up by causing problems from kidney failure, heart attacks, eye problems, strokes, nerve damage , skin problems and many more.

Who can help manage my blood sugar?

Correct regulation of your blood sugar level should be done in consultation with a doctor and/or healthcare professional.  Why?

It would be easy to put a chart of correct blood sugar ranges and say you must be in a certain range.  That would be actually wrong.  Every person is unique and situation is different.  Saying you must be in a certain group can be harmful if not guided by professionals that know how to manage blood sugar levels.  They will help you with everything from time to take a test to how many time a day to test and what symptoms affect you. You should understand your body and be aware of warning signs for extreme fluctuations in your glucose levels.

How To Take Your Blood Sugar Levels

There are three essential skills to good management of your diabetes mellitus.  These little tasks go hand in hand.  Firstly, and the most important, is how to take a blood sugar level.  I step through the process in this video


How To Calibrate Your Blood Sugar Machine

Also, it is essential to know how to calibrate your glucometer to ensure that you are getting accurate blood sugar levels every single time.  You are making decision about how best to manage your diet or how much insulin to give, so you need to make sure that you are basing this assessment on a sound reading.  The only way to know that is to regularly calibrate your glucometer every time you start a new batch of testing strips.  In this Nurse on the Go Video, I go through the step-by-step process on how to do that.

Troubleshoot Testing Your Blood Sugar Levels

Finally, taking blood sugar levels seems like an easy process, but sometimes things don’t always go as planned and so it is essential to have an understanding of how to get yourself out of trouble.  I discuss the most common problems that occur when regularly testing and how to navigate them

We’ve made a couple of documents that will help you keep track of where you are at with your blood sugar levels.  It’s a simple chart similar to what nurses use every day when diabetics are in hospital and we are responsible for monitoring their blood sugar levels.  There are two formats: one excel spread sheet that you can download and save onto your computer.

This will allow you to keep electronic records and always have them on your computer for whenever needed.   It’s not a bad idea to keep these for the longer term.  It may come in handy to take a retrospective one day at what your historical blood sugar levels have been.
