Hypertension is a common disease that affects about 15 to 205 of the population. Many people do not know they have high blood pressure, because the body becomes accustomed to high levels, which, however, will commit a silent organs like the heart, kidneys, brain and eyes. But you can avoid this situation and even prevent the onset of hypertension.
What is hypertension?
It is the pressure exerted on the heart arteries, which can be measured by two values, maximum pressure (systolic) with respect to pressure is that the heart to pump blood towards the organs and the minimum pressure (diastolic) with regard to accommodation of blood in blood intervals.
What are the contents of normal pressure?
For adults, the World Health Organization accepted as normal until a maximum pressure of 140 and a minimum pressure of 90 mmHg (14 by 9). However, there has been a tendency to reduce these levels because of the difficulty in demarcating the limits of normal values and changes that indicate hypertension.
What is hypertension?
It is a disease of multiple causes, characterized by a sustained increase in blood pressure values. Values of 14 for 9, even if the person is calm and at rest, can now be considered abnormal.
What happens in the body of a hypertensive?
Your arteries become narrow and difficult passage of blood, which is why the heart needs to exert greater pressure to pump it.
What are the symptoms?
Most people who have hypertension have no symptoms. When present, however, can manifest as headaches, nosebleeds, dizziness and ringing in the ears. Others such as palpitations, chest pain, shortness of breath, swelling, vision changes, memory loss and balance, paleness, urinary problems and pain in the legs show that the target organs of the disease may be compromised. In these cases, one should seek immediate medical attention.
What are the causes of disease?
In 90 to 905 cases there is a known cause of hypertension. But eventually, endocrine and kidney problems, pregnancy, frequent use of some drugs (contraceptives, decongestants, antidepressants, steroids, and appetite suppressants) of cocaine, as well as neurological diseases may be causes of hypertension.
Hypertension as can be diagnosed?
The diagnosis is based on the measurement of blood pressure with an apparatus used in hospitals, clinics and offices. Although simple pressure measurement alone is influenced by several factors. Because of this, today’s medicine uses additional resources to diagnose hypertension.
What resources are these?
One is the stress test, which measures the pressure of the individual during physical exertion and can show if it has risk of developing hypertension. Another is the ambulatory blood pressure (MAP), which registers the pressure of the patient 24 hours over the course of their daily activities and sleep, providing data relevant to the doctor. But none of these features replaces the patient’s clinical evaluation and blood pressure measurement in the office.
Why is it important control hypertension?
Because the life expectancy of an individual with hypertension is 40% lower than that of a healthy individual, over the years. The fact is that, while struggling to pump blood, the heart of hypertensive patients are vulnerable to heart failure. Moreover, due to the increased pressure will wearing vessels, which may break and cause a stroke. This wear also facilitates the accumulation of fatty plaques in arteries, predisposing the individual to the infarction. Another serious consequence is the impairment of the kidney filtration system.
What is the treatment?
For some, a diet low in salt and fat, in addition to lifestyle changes of3 9deixar smoking, drink less alcohol, exercise and weight loss) are sufficient to maintain peer pressure controlled. Others, however, require drugs. But only your doctor can determine the type of hypertension, assess the state of the target organs of the disease and prescribe the proper treatment.
How can you prevent hypertension?
Lead a healthy lifestyle, maintaining a healthy weight, avoid alcoholic beverages, exercise, not smoking and eat a balanced diet, with moderate consumption of salt are preventive attitudes. It is also recommended that every person over 40 years to make periodic measurements of pressure – especially those who have a history of high blood pressure in the family – always under medical supervision.
Any high pressure is already sign of hypertension?
No. The pressure varies within 24 hours of the day and follows a rhythm of its own, influenced by the psychological state of the person, habits and daily activities. So, can rise momentarily but then go back to normal. To be labeled as hypertensive, the patient should present pressure levels above the normal range obtained in media row, in two or more doctor visits.
