Hypertension

hypertensionWhich is it?

Hypertension is the increase in blood pressure chronically. It’s a disease no symptoms for a long time and, if untreated, can trigger severe complications such as myocardial infarction, cerebral hemorrhage or thrombosis, which can be avoided if handled properly. The first consequences of hypertension are suffered arteries that harden as they bear high blood pressure continuously, thicken and may be impeded the passage of blood through it. This is known as atherosclerosis.

Causes

The mechanism of hypertension most common, called “essential hypertension”, “primary” or “idiopathic”. In essential hypertension have not yet described the specific causes, but has been linked with a number of factors that are usually present in most people who suffer. Should be separated from those related to heredity, sex, age and race and rarely modifiable, those that could be changed by varying habits, environment, and morals of individuals, such as obesity, sensitivity sodium, excessive alcohol consumption, oral contraceptive use and a very sedentary lifestyle.

  • Inheritance: when transmitted from parent to child inherits a tendency or predisposition to develop high levels of blood pressure. Exact mechanism is unknown, but past experience shows that when a person has a parent (or both) with hypertension, the chances of developing hypertension are twice those of other people with both parents without a history of hypertension.
  • Sex: Men are more predisposed to high blood pressure than women until they reach the age of menopause. From this stage the frequency in both sexes is equal. This is because nature has endowed woman with a protective hormones while you are of childbearing age, estrogen, and therefore have a lower risk of cardiovascular disease. However, in younger women there is a special risk when taking birth control pills.
  • Age and Race: Age is another factor, unfortunately coded, which will influence blood pressure numbers, so that both systolic and diastolic pressures, or maximum or minimum increase with age and is logically a greater number of hypertensive patients with increasing age. As for the race, people of African descent are twice as likely to develop hypertension than whites, also have a worse prognosis.
  • Overweight: Overweight individuals are more likely to have higher blood pressure than normal-weight individual. As weight increases blood pressure rises and this is much more evident in those under age 40 and women. The frequency of hypertension among the obese, regardless of age, is two to three times higher than individuals of normal weight. It is unclear whether obesity is itself the cause of hypertension, or if there is an associated factor that increases pressure in overweight, although recent research suggests that obesity is associated with another series of alterations that be in part responsible for increased blood pressure. It is also true that the reduction in weight makes these alterations disappear.
