Your heart pumps your blood through tubes (blood vessels) called arteries and veins. When your blood moves through the blood vessels, it pushes against the inside of them and creates pressure. Blood pressure is the pressure created inside your arteries and veins when your blood flows through.

High blood pressure and your kidneys

High blood pressure (hypertension) means your heart is working too hard to pump your blood. It usually shows no signs. The only way to know if you have high blood pressure is to get tested.

High blood pressure can cause kidney disease.
When blood lows too forcefully through the tiny blood vessels in your kidneys, this can hurt or weaken these tiny vessels. Over time, this can lead to kidney disease.

Kidney disease can cause high blood pressure.
Healthy kidneys help control your blood pressure. When your kidneys don’t work well, they don’t do a good job controlling your blood pressure. This can cause high blood pressure.

What does a blood pressure test do?

  • It measures how hard your heart is working to pump blood.
  • It uses an inflatable cuff that tightens around your arm and slowly loosens. As it loosens, a meter measures the pressure in your arteries when your heart pumps.
  • A blood pressure test can be done by your doctor or nurse, at home, or in some pharmacies and grocery stores.
  • Check your blood pressure regularly, and tell your doctor if you get a high result.
