High blood pressure, or hypertension, is a state in which the force of the blood against the artery walls is high such that it may ultimately cause severe heart problems or other health issues. High blood pressure is said to be a silent killer.

The amount of blood produced by the heart and the degree of arterial blood flow resistance influence blood pressure. Blood pressure rises in direct proportion to how much blood the heart pumps through constricted arteries.
The risk of significant health problems including heart disease and stroke increases double when high blood pressure is uncontrolled. Fortunately, excessive blood pressure can be quickly identified, managed, and treated.

Blood pressure is measured by a sphygmomanometer. There are three types of these devices- mercury sphygmomanometer, aneroid sphygmomanometer and digital sphygmomanometer. A sphygmomanometer is a device with an inflatable rubber cuff that is applied to the arm and connected to a column of mercury next to a graduated scale enabling the determination of systolic and diastolic blood pressure by increasing and gradually releasing the pressure in the cuff. Along with it, a doctor uses a stethoscope to hear the blood flow in arteries and veins.

Despite readings showing dangerously high levels, the majority of persons with hypertension do not exhibit any symptoms.
Some people may experience headaches, breathlessness, or nosebleeds, but these symptoms are vague and typically don't show up until high blood pressure has gotten quite bad.
There are many types of high blood pressure –

Treatment of high blood pressure may involve many options like:
Taking one or more drugs is often more effective for many persons with high blood pressure than taking doses of just one medication. Healthcare professionals may suggest different drugs depending on the patient's body, medical history, and degree of the ailment.
High blood pressure sufferers need to watch their sodium and cholesterol intake and keep up a balanced diet.
It could be advised to follow a diet high in protein, fiber, and other nutrients.
