Prehypertension is defined as slightly raise in blood pressure. Prehypertension will mostly turn into high blood pressure (hypertension) unless you make lifestyle changes, such as getting more exercise and eating healthier foods. Both prehypertension and high blood pressure increase your risk of heart attack, stroke and heart failure. Prehypertension is a systolic pressure from 120 to 139 millimetres of mercury (mm Hg) or a diastolic pressure from 80 to 89 mm Hg.
This Prehypertension does not cause symptoms. In fact, severe high blood pressure may not cause symptoms. The only way to detect prehypertension is to keep track of your blood pressure readings. Have your blood pressure checked at each doctor's visit - or check it yourself at home with a home blood pressure monitoring device. Ask your doctor for a blood pressure reading at least once every two years starting at age 18. You may need more-frequent readings if you have prehypertension or other risk factors for cardiovascular disease.
Treatment: Any factor that increases pressure against the artery walls can lead to prehypertension. Atherosclerosis, which is the build-up of fatty deposits in your arteries, can lead to high blood pressure. Sometimes an underlying condition causes blood pressure to rise. Certain medications - including birth control pills, cold remedies, decongestants, over-the-counter pain relievers and some prescription drugs - also may cause blood pressure to temporarily rise. Illegal drugs, such as cocaine and amphetamines, can have the same effect.
Statistics: In Israel, the survey on Prehypertension got the result as, of the 426,033 subjects 18.6% had a diagnosis of hypertension or used antihypertensive medications. Only 40.8% of the other 346,799 subjects had had their BP measured in the preceding 2 years. BP recording rates were higher in females than in males (45.1% vs. 36.3%) and higher in elderly subjects than in young subjects (56% aged 66-75 years vs. 32% aged 18-25). Pre-hypertension was observed in 80,625 (23.2%) of the 346,799 while only 56,113 (16.2%) had normal BP records. The prevalence of pre-hypertension increased with age (13.3% aged 18-25 vs. 44.8% aged 66-75), and was more prevalent in men than in women (24.0% vs. 22.5%).
