Definition of hypertension
Arterial hypertension, also called high blood pressure, is a medical condition where the blood pressure in the artery walls is sufficiently high so that the end can lead to health problems such as heart disease. This is because the heart has to work harder to circulate blood efficiently through the blood vessels throughout the body.
How can cause high blood pressure?
Blood pressure is determined by two factors, namely the amount (volume) of blood pumped, the heart and the amount of bleeding resistance arteries. This is in agreement with the laws of physics, the more blood is pumped, the reduction of the coronary arteries, the increased blood pressure.
If the measurement of blood pressure and the result has been high, and not necessarily transferred to the person with hypertension. He was to define or diagnose a person has high blood pressure, at least, check blood pressure (voltage) three times at different times (at least 5 minutes) during hibernation comfortable with the results of more or equal to 140/90 mmHg.
A person can have high blood pressure (hypertension) for years without symptoms. Therefore, it is also known that a person who has high blood accidentally, when you see a doctor for other diseases. Therefore, knowledge of blood pressure is important for early detection if you drew, as control of high pressure and blood processing time.
High blood pressure typically develops over many years, and that affects almost everyone at some point. Fortunately, high blood pressure can be easily detected. And he raised even known, then treatment can be done to control blood pressure. Since uncontrolled hypertension remains high alias continues, the risk of serious health problems will increase, including andstroke heart attacks.
Symptoms of hypertension
Most people with high blood pressure has no signs or symptoms, even if it is under pressure ditensi reached dangerous levels.
However, some people experience initial stages of high blood pressure may include headaches, dizziness or nosebleeds, signs and symptoms usually occur when the blood pressure is high – that endanger life, even at this stage -.
See why blood pressure (voltage), which regularly:
For children 18 years or every two years.
Children aged 3 years or more is tested, usually a year of study in the context of blood pressure.
For those who have high blood pressure, frequent checks are detected according to doctor’s instructions.

The cause of hypertension
The cause of high blood pressure according to the type of itself to high blood pressure, there are two types of high blood pressure (hypertension).
Primary hypertension (essential)
Hypertension Primary hypertension is a type of majority for adults, called primary or essential or idiopathic because the cause is unknown and the pressure of this type are usually come with the years.
In this secondary hypertension, high blood pressure caused by the causes of the illness or underlying condition. Secondary hypertension may appear suddenly and cause hypertension. Various conditions and medications that can cause secondary hypertension, including:
Some defects in the blood vessels at birth (congenital)
Certain medications, such as birth control pills control medications against colds, decongestants, painkillers and prescription drugs
Illegal drugs such as cocaine and amphetamines
