Understanding High Blood Pressure

Key Information

• High blood pressure usually has no symptoms. The only way to know if you have it is to get it checked.
• We diagnose high blood pressure with a simple test. A reading consistently over 140/90 in the clinic, or 135/85 at home (below the age of 80), is considered high.
• Over time, high blood pressure puts extra strain on your heart and blood vessels, increasing your risk of serious problems like heart attacks, strokes, and kidney disease.
• Risk factors include age, family history, ethnic background, and lifestyle choices like diet and smoking.

What Happens Next?

Because high blood pressure usually has no symptoms, getting checked is the only way to know your numbers.

We recommend that all adults over 40 have their blood pressure checked at least every five years. You can get this done here at the practice or at many local pharmacies.
