High blood pressure is especially common in Western industrialized countries. So there is more than 25 percent of the population suffer from hypertension. The higher the age, the greater the risk of high blood pressure. In medicine, a distinction for high blood pressure between two forms of primary hypertension and secondary hypertension. A primary cause of hypertension, the blood pressure rise is not usually known. This is different from the secondary form. It is the consequence of certain diseases. Thus approximately 10 to 15 percent of all high blood pressure patients suffering from hypertension, has organic causes.
The most common secondary hypertension by kidney and vascular diseases and diseases of the endocrine system is caused. Especially kidney disease is the reason for the secondary form. It is differentiated between diseases of the kidney tissue and renal arteries. To diseases of the kidney tissue can cause damage by diabetes, chronic inflammation or mechanical compression. Similarly, an adrenal tumor for hypertension to be the cause. However, disturbances in the hormonal household as in Conn's syndrome or Cushing's syndrome are often the trigger for a secondary hypertension. Another possible cause is a narrowing of the aorta, the aorta, the aortic arch (coarctation). This narrowing causes a rise in blood pressure. Since the kidneys which are the bottleneck, with reduced blood flow only to be, this will eventually lead to arterial hypertension. Occasionally, even the sleep apnea syndrome secondary hypertension trigger. The increase in blood pressure occurs in this case, especially at night.
To symptoms, it is not always with hypertension. Sometimes, however, connect the symptoms like headache in the morning, racing heart , shortness of breath , nausea , dizziness , insomnia, fatigue , ringing in your ears or nose bleeds . In most cases, hypertension does not felt only by secondary damage. However, if blood vessels and organs affected, the risk of coronary heart disease. At worst, it can cause a heart attack or stroke occur.
Just as primary hypertension, hypertension can also be the secondary by repeated blood pressure measured at different times of day notice. In addition, the patient's history is very important in order to find information on the underlying disease. To treat the hypertension secondary effect, the underlying disease-causing to be corrected. Therefore, the treatment on the specific cause of disease. Is there such as a renal artery stenosis, we administered to the patient either medication or take an extension of the renal arteries using a catheter prior to what is known as percutaneous transluminal Arteriendilatation. If the narrowing of the artery removed, the blood pressure may drop again. In endocrine disease is often a surgical procedure performed to the secondary hypertension to eliminate the trigger.
