High blood pressure (hypertension) – Diagnosis and treatment …

High blood pressure (hypertension) is diagnosed if the blood pressure reading is equal to or greater than 130/80 mm Hg. A diagnosis of high blood pressure is usually based on the average of two or more readings taken on separate occasions. Blood pressure is grouped according to how high it is. This is called staging. Staging helps guide treatment.
