Under normal conditions, the blood pressure of man fits the needs of the circulatory situation, the complex regulation of hormones and is also on the autonomic nervous system. With increased physical stress, the blood pressure, as well as for pain, psychological factors and stress, at rest it sinks. Blood pressure is also subject to daily variations: the highest value arising in the morning, late afternoon and early evening. During the lunch time (especially after lunch), blood pressure drops off significantly, while most of the night. The blood pressure values of the people are stable in a certain context. Through a series of disease processes, this system out of balance blood pressure fall - with permanently elevated values, but also to low levels or inadequate blood pressure fluctuations:

* Primary hypertension (essential hypertension): In approximately 80% of cases of hypertension are available genetic causes, which led, in particular in old age in a decrease in vascular elasticity. Under these conditions must be that heart to fight against increased resistance, which manifests itself as high blood pressure. In addition to hereditary factors contribute to the emergence of a number of other risk factors of hypertension:
o Poor nutrition and obesity
o stress,
o alcohol and smoking,
o existing diseases such as diabetes or dyslipidemia.
* Secondary hypertension: In contrast, are responsible for the secondary concrete body shape causes for the increase in blood pressure. These include anomalies of the cardiovascular system itself, such as the congenital narrowing in the descending part of the aorta (coarctation), but also diseases of the kidneys or the endocrine system. Since the kidneys act as a major organ of elimination a central role in the regulation of water balance and blood pressure, are disorders of this organ often associated with blood pressure problems. All pathological processes that lead to a hypoperfusion of the kidney, such as a narrowing of the renal artery may be associated with elevated blood pressure.
