“High blood pressure causes kidney failure.”
Really? So if my blood pressure is 140/90 (it is actually lower than that), my kidneys will fail? From an Internet site:
“If high blood pressure damages the blood vessels that deliver blood to your kidneys...”
At what pressure will the blood vessels be damaged BY PRESSURE?
This goes back to my point: Blood pressure is a SYMPTOM, not a CAUSE. If you have damage to your arteries, it can raise your blood pressure AND damage your kidneys, but the blood pressure is an associated symptom, not the cause of the damage!
Now if your blood pressure was super high, it might do structural damage. But how high would that be? I had uncles with very high blood pressure who lived into their 90s, so the pressure itself isn’t the issue.
My understanding is that 140/90, used to be considered “normal”, but they keep lowering it, in order to sell more pills.
Kidney damage from high blood pressure is worse the higher the pressure, and worse the more time one is at a higher pressure.
It’s not an on/off switch at some high pressure level.
