Bp Affecting The Test Strip Meter Accuracy?

[ickihun]

If this is a repeat I apologise. I was in the middle of editting this new thread when it refused to save.

Blood Pressure seems to be affecting my blood glucose results on my meter. I'm unsure if my hba1c will reflect as I'm questioning whether low blood pressure or high blood pressure will show a different bg result?
On this occasion and a previous one of taking co-codamol for scatica my blood pressure has reduced as my bgs on my meter.
I read somewhere that high blood pressure was related to cardiac disease and diabetes can bring on cardiac disease. Is there a relationship between blood pressure and bg results???

I do not think BP affects BG levels. BP is affected by the blood thickness and also the hardness of your arteries. Meter readings can vary a lot and be within calibration. Also this calibration is set for 99% of readings so you can still have 1% of readings that are outside the calibration range.

What will be making more difference to your reading is sweat on your fingers or any other contamination (can include soap). If I do not believe a reading I will smear blood over the area to take a sample to make sure it is "cleansed" and then take another two readings.

As for high BP and cardio disease it is because of the stiffening arteries.

Blood pressure is the pressure of the liquid in the system. So how hard your heart is having to beat to get your blood round, how strong your arterial walls are.

Blood sugar is the make up of the liquid in the system. I can't see the logic of how blood pressure might impact on blood sugar. If you fill a balloon up with water and squeeze it really hard, it won't make the water more sugary.

I also can't see how high blood pressure might impact on the accuracy of test results, whether hba1c tests or blood glucose finger pricks.

However, high blood sugar will cause high blood pressure. Blood that is high in glucose is more viscous and will require more pressure to get it round the system.

I think you are being over optimistic to suggest that high bp gives inaccurately high blood sugar readings (which is what the title of the thread reads like, to me anyway) rather, if you have noticed that high blood sugar readings coincide with high blood pressure that could be because higher blood sugar can cause raised blood pressure.

@ickihun I tend to agree with this. One of the issues with T2` is that there is excess insulin in the system, and when blood glucose levels are higher, this is likely to be exacerbated.

What is known about hyperinsulinaemia is that it has a direct correlation with hypertension. There have been studies in this area, (one of which is documented here, https://www.ncbi.nlm.nih.gov/pmc/articles/PMC423608/) and what has been shown is that under glycaemic load producing an insulin load, blood pressure is increased. This was a single study, but seems in line with what we know of the physiology.

The likelihood, therefore, is that when you see high blood glucose levels, you will have an even higher insulin load than normal, and this will result in higher blood pressure.

Since reading your initial post @ickihun I have been having a read around on the web as it seems like quite an interesting subject.

There may be some correlation between blood pressure and blood glucose but if anything, it looks to me like it may be in the opposite direction to your supposition.............

Diabetes and Blood Pressure
In many cases of diabetes, blood sugar affects the blood pressure. When glucose stays in your bloodstream too long, it can act like a slow poison, according to the National Kidney Disease Education Program. Uncontrolled blood sugar can damage the nephrons, the functional units of your kidneys that play a role in regulating your blood pressure. This can cause high blood pressure.

And there seems to be a higher incidence of T2 in people with high blood pressure, also quite interesting.....
