Prehypertension in Adults
If you believe you have low or normal blood pressure, you may be off the mark. You might have prehypertension. Prehypertension occurs when you have elevated blood pressure, but not high enough to require medical treatment. When your blood pressure is elevated, the risk of developing hypertension increases dramatically.
Hypertension, or high blood pressure, is diagnosed when a blood pressure reading of 140/90 mmHg (millimeters of mercury) or greater is noted. The level must be seen on at least two readings to be officially diagnosed. The upper number is the systolic pressure when your heart contracts. The lower number is the diastolic pressure when your heart relaxes.
Having prehypertension is your cue to take action. It is important to take steps now to lower your blood pressure before medical treatment is necessary.
As mentioned before, people with prehypertension are more likely to develop full-blown hypertension. They are also more likely to develop associated health problems. Heart disease, stroke, kidney disease, and impaired vision are all associated with hypertension.
Studies indicate that cardiovascular risk increases as blood pressure rises above 115/75 mmHg. In fact, your risk doubles with every 20 mmHg rise in systolic pressure or with every 10 mmHg rise in diastolic pressure.
