Helping control blood pressure
One of the important functions of the kidneys is to regulate blood pressure.
Healthy kidneys make hormones such as renin and angiotensin. These hormones regulate how much sodium (salt) and fluid the body keeps, and how well the blood vessels can expand and contract. This, in turn, helps control blood pressure.
They do this by regulating:
High blood pressure (also called hypertension) caused by a breakdown in these functions is common in people with kidney failure. It is also a complication, a secondary condition caused by kidney failure.
"I never knew high blood pressure could cause kidney disease. I didn't ask my doctor enough questions. If I had known, I would do things so much differently." -Perry Aldridge, kidney patient
