High blood pressure

What blood pressure numbers mean and everyday steps that help keep them in a healthy range.

Overview

Illustration of a heart with a pulse line
High blood pressure often has no symptoms, so regular checks matter.

Blood pressure is the force of blood pushing against artery walls. When it stays high, the heart works harder and the risk of heart attack, stroke and kidney disease goes up.

Know your numbers

A reading has two numbers, such as 120/80. Your care team will explain what your readings mean and what target is right for you.

Everyday steps

  • Limit salt (sodium) and processed foods
  • Stay active most days of the week
  • Limit alcohol and avoid tobacco
  • Take medicines as prescribed

When to get help

Call 911 for a very high reading with chest pain, shortness of breath, back pain, numbness or weakness, vision changes, or difficulty speaking.
