Love and marriage; horse and carriage; kidneys and blood pressure - inadequate kidney function can cause high blood pressure and high blood pressure can cause serious kidney damage. So, those of us in the Lone Kidney Club need to pay particular attention to our blood pressure.
In following up on some speculations I'd arrived at on this subject, I discovered an excellent website which I think should be recommended reading for all of us:- http://www.bloodpressure-drs-practical-guide.com/pulsepressure.html
One point that is made clear in that website affects the majority of us, in our Club - i.e. those who are not in the first flush of youth - and that is that what we thought we knew about blood pressure now turns out to be not the whole story.
Below age 50 or so, it is bad news if you have a high diastolic blood pressure; from about 50 to about 60, the systolic figure becomes increasingly important; but for us oldies it's not good if either reading is high but it's worse still if our systolic pressure is a lot higher than our diastolic. So, contrary to what you'd expect, 170/100 is better than 170/70 for anyone in their 60s or older. A systolic of 170 is bad, and so is a diastolic of 100. However, although a diastolic of 70 would be fine with a systolic of, say 120 or 130, it's not at all good to have a difference of 100 (170 minus 70) - better to have a (bad) diastolic of 100 but a smaller difference of 70 (170 minus 100). There is a growing body of recent scientific research work that shows this to be true.
I raise my hat to the retired specialist who has gone to the trouble to put together such a valuable and informative site. In it you'll also find much good advice on how to lower your blood pressure for free by tweaking what you eat and drink, taking suitable exercise and so on. Not everyone is as keen as I am on reading this sort of stuff but if you do I'm sure you'll benefit from it.
