High blood pressure or hypertension is the most common cardiovascular disease. It is a chronic medical condition in which the blood pressure in the arteries is elevated. This requires the heart to work harder than normal to circulate blood through the blood vessels.
One can have high blood pressure for years without any symptoms. Uncontrolled high blood pressure increases the risk of serious health problems, including heart attack and stroke.
A blood pressure reading has a top number (systolic) and bottom number (diastolic). The ranges are:
Normal: Less than 120 over 80 (120/80)
Pre hypertension: 120-139 over 80-89
Stage 1 high blood pressure: 140-159 over 90-99
Stage 2 high blood pressure: 160 and above over 100 and above
A proportion of people with high blood pressure reports:
Headaches (particularly at the back of the head and in the morning)
Tinnitus (buzzing or hissing in the ears)
Altered vision or fainting episodes.
