Full Answer

The top number of a blood pressure reading is the systolic blood pressure, explains WebMD. This occurs when the heart contracts, putting pressure on the arteries as it pushes blood throughout the body. The bottom number is the diastolic blood pressure, which shows the pressure on the arteries when the heart is resting between beats.

A blood pressure reading of 90/60 or less indicates low blood pressure, which is unhealthy in some cases but generally indicates a lower risk for stroke or heart disease, states Blood Pressure UK. A reading between 90/60 and 120/80 is an ideal and healthy blood pressure reading. A reading between 120/80 and 140/90 is slightly higher than it should be. A reading between 140/90 or higher indicates high blood pressure or hypertension, indicating the need for lifestyle changes and possibly high blood pressure medicine.

If blood pressure is normal, or less than 120/80, it should be checked every two years or as the doctor suggests, advises WebMD. Blood pressure between 120/80 and 140/90 is borderline high and should be checked every year, or more often if suggested by the doctor. Blood pressure above this is high blood pressure and requires a doctor's advice as to proper treatment.
