Tina Turner had a history of high blood pressure and kidney disease. Here’s how one leads to the other
By Karen Dwyer, Deakin University
Legendary singer Tina Turner, who died this week at the age of 83 after a long illness, has written about her history of high blood pressure and kidney disease, leading to a kidney transplant.
Turner should be applauded for her willingness to share her medical history to publicise the importance of looking after your kidneys, just months before she died.
Turner’s family has not confirmed how she died. But Turner’s openness with her long-standing illness is a reminder for us all to keep an eye on our blood pressure, and to control it, if we are to avoid complications.
Here’s why controlling your blood pressure is so important and what can happen if we don’t.
Why is high blood pressure linked to kidney disease?
There’s a bi-directional relationship between blood pressure and kidney disease.
That means high blood pressure increases the risk for kidney disease and once you have kidney disease, it further promotes high blood pressure. It’s a vicious cycle.
In some cases, it’s hard to determine which one came first.
Uncontrolled blood pressure exerts a lot of pressure on the kidney. That leads to scarring and damage. If we looked inside the kidney, we’d see large areas of scarring. Once you have scarring, that tissue isn’t working properly and can start to leak protein into the urine. That then pushes up the risk of progressive kidney disease, leading to kidney failure, heart disease and premature death.
The kidney itself is integral to maintaining blood pressure. Kidneys obviously maintain fluid balance by passing urine, but they also have important hormonal jobs which are vital to maintaining blood pressure.
So, once you get kidney disease, blood pressure can be really hard to manage. It’s like a hammer and nail, and the nail is the kidney. If you have high blood pressure, the hammer is hitting the nail really, really hard.
