High Blood Pressure - Hypertension

Major Cause of High Blood Pressure - Hypertension

What is hypertension?

The heart is a muscle that works like a machine pumping. When he sends a stream of blood to the circulatory channels and push the pressure it is called systole. When the heart relaxes between beats, it decreases the pressure in the circulatory tract, and this is called diastolic pressure.

The normal pressure is below 140 for the systolic and below 85 for diastolic.

These are the circumstances that increase blood pressure transiently values:

-- The physical effort. --A change in temperature, the cold. -- The move to a different climate. -- Strong Emotions, pain and fear. -- Voltage, public speaking, discussion, energetic, loud noises, among others.

The blood pressure causes it to produce a reaction that tends to raise the alert, as they are repeated shots of blood pressure, this tends to fall. So do not take more than two or three times the pressure and is considered the last or the average of all real pressure.

Common symptoms of hypertension include acute anxiety, dizziness, fatigue and headaches. If blood pressure is serious symptoms may include confusion, distortion of vision, nausea, vomiting, chest pain, shortness of breath, ringing in the ears, nose bleeding and excessive sweating.

The pressure can change from one moment to another depending on the activity, moods, with position changes, exercise or during sleep. People with high blood pressure need not be overly anxious, compulsive or "nervous."

A very important fact is that you can have high blood pressure and no know because usually no symptoms. That is why it is called a "silent death".

In 90% of cases of hypertension were unaware of the causes that lead. This type is called primary hypertension.

What is the cause of hypertension (HBP)?

In essential hypertension have not been described yet, their specific causes, but has been linked to heredity, sex, age and race, to change habits, environment, and habits of people, such as obesity, sodium sensitivity, excessive alcohol consumption, use of oral contraceptives and a sedentary lifestyle.

Inheritance from parents to children is transmitted predisposition or a tendency to develop high levels of blood pressure. When a person has a parent (or both) hypertension / s, the chances of developing hypertension are twice those of other people with both parents normotensive.

Sex: Men are more predisposed to develop hypertension than women until they reach the age of menopause, after which the frequency in both sexes is equal.

This is because nature has given to women while in age with a protective hormones are estrogen and therefore have less risk of cardiovascular disease. In this way nature protects women by ensuring procreation. However, in younger women there is a particular risk when they take pills.

Age and race: The age is another factor that will influence the numbers of blood pressure, so that both systolic blood pressure or the maximum or minimum diastolic increase naturally with age and is more in hypertensive older age groups.

As for the race, noting that only black people are twice as likely to develop hypertension than those of whites also have a worse prognosis.

Overweight: The relationship between weight and blood pressure, and overweight and hypertension, has been known for many years, and reduction of overweight is used to treat the same too long.

We must assume that an overweight individual is more exposed to higher blood pressure than individuals with normal weight. As you gain weight increases blood pressure and this is much more evident in those under 40 years and in women.

The frequency of hypertension among the obese, at any age is considered is two to three times higher than among individuals of the same age who are in their ideal weight.

Is not clear whether obesity is itself the cause of hypertension or if there is an associated factor that increases the pressure in people with overweight, although recent research suggests that obesity is associated with another series of alterations that would partly responsible for the increase in blood pressure. It is also true that the reduction in weight makes these alterations disappear.

Diet and Prevention of Hypertension:

Excessive salt in the diet causes fluid retention and increased tension. To reduce the tension, the first step is to decrease the total intake (including that contained in the bread, broth concentrates, prepared foods, etc.). To an amount less than one teaspoon per day, which is the required daily our diet.

It can improve blood pressure, eating more fruits and vegetables that contain potassium, and thus promote this reduction.

Other dietary factors:

The snuff and drinks with caffeine have an effect on short-term increase in TA, but there is clear evidence that its routine use can contribute to a sustained hypertension. However, the use of snuff can accelerate the process of atherosclerosis in people with hypertension. Also, the habitual abuse of alcohol can contribute to the development and maintenance of hypertension.

It should also be aware that certain medications increase vascular resistance, among them are the non-steroidal anti-inflammatory drugs, contraceptives, cute mimetics and steroids.

A program of aerobic exercise helps strengthen the heart, control weight and to lower the TA. No one knows the exact mechanism by which helps to lower the TA. You must make a proper exercise of each person and each age, so the realization of smooth half-hour race 2 or 3 days per week is enough for most people.

Hypertension, also referred to as high blood pressure, HTN or HPN, is a medical condition in which the blood pressure is chronically elevated.Hypertension can be classified either essential (primary) or secondary. Essential hypertension indicates that no specific medical cause can be found to explain a patient's condition. About 95% of hypertension is essential hypertension. Secondary hypertension indicates that the high blood pressure is a resul
