Hypertension simply means high blood pressure. High blood pressure typically develops over many years, and it affects nearly everyone eventually. Fortunately, hypertension is easily detected and once you know you have it, you can control it.
Blood pressure is determined by two basic factors:
Blood pressure is measured when the heart beats while pumping blood (referred to as 'systolic' pressure) and when the heart is at rest in between beats (referred to as 'diastolic' pressure). Normal blood pressure is below 120/80 mmHg where the 120 refers to the systolic and the 80 the diastolic pressures.

If you have diabetes or chronic kidney disease, hypertension is defined as 130/80 mmHg or higher. High blood pressure numbers also differ for children and teens.
Blood pressure doesn't stay the same at all times. It lowers with sleep and rises upon waking. Blood pressure also rises when one gets excited, nervous, or active. If your numbers stay above normal most of the time, you're at risk for health problems and the risk grows as blood pressure numbers rise. "Prehypertension" means there is a tendency to develop high blood pressure, unless steps are taken to prevent it. If, upon treatment for high blood pressure, readings are consistently obtained in the normal range, then it means that the pressure is under control and not necessarily that the disease is gone. Note, however, that the complete mechanism governing the progression of the disease is not clear so that treatment now focuses on symptoms of the disease.
If you're being treated for HBP and have repeat readings in the normal range, your blood pressure is under control. However, you still have the condition.
Most people with high blood pressure have no signs or symptoms, even if blood pressure readings reach dangerously high levels. Hypertension can be present for years without one knowing it. During this time, the condition can damage your heart, blood vessels, kidneys, and other parts of your body.
Although a few people with early-stage high blood pressure may have dull headaches, dizzy spells or a few more nosebleeds than normal, these signs and symptoms typically don't occur until high blood pressure has reached a severe — even life-threatening — stage.
Some people only learn that they have Hypertension after the damage has caused problems, such as coronary heart disease, stroke, or kidney failure.
Knowing your blood pressure numbers is important, even when you're feeling fine.
