Uncontrolled vital sign (hypertension) is a common condition in which the long-term force of the blood against your artery walls is high enough that it may eventually cause health problems, like heart disease.
Blood pressure is resoluted both by the amount of blood your heart pumps and the amount of resistance to blood flow in your arteries. The more blood your heart pumps and therefore the narrower your arteries, the upper your blood pressure. A vital sign reading is given in millimeters of mercury (mm Hg).
Most people with high blood pressure have no signs or symptoms, whether or not blood pressure readings reach dangerously high levels.
A few people with high blood pressure may have headaches, shortness of breath or nosebleeds, but these signs and symptoms aren't specific and typically don't occur until high blood pressure has reached a severe or life-threatening stage.
There are two sorts of high blood pressure.
Primary (essential) hypertension
For most adults, there is no identifiable cause of high blood pressure. this sort of high blood pressure, called primary (essential) hypertension, tends to develop gradually over a few years .
Some people have high vital sign caused by an underlying condition. this sort of high blood pressure, called high blood pressure , tends to seem suddenly and cause higher blood pressure than does primary hypertension.
