The dangerously high blood pressure

First of all, high blood pressure is dangerous sudden sharp rise in blood pressure - hypertensive crisis, which may lead to stroke, myocardial infarction, severe complications from the kidney and so on. As a result, a person may remain disabled for life.

But the danger exists and no crises, when high blood pressure does not manifest itself for a long time. Since the blood vessels are in a constant state of spasm, organs and tissues do not get enough nutrients and oxygen. Particularly affected by this brain, heart and kidneys. All organs and tissues against this background develop sclerotic phenomenon - instead of tissue of an organ grows connective tissue, which leads to organ dysfunction.

That is why when a person has untreated hypertension disrupted memory, motor coordination, trembling of the limbs appear, shortness of breath, urination disorders, significant renal dysfunction, and so on. Diseases caused by high blood pressure, associated with dysfunction of internal organs - brain, heart, kidneys, eyes and so on. Effects of high pressure can be very heavy, which is why it should be as soon as possible to identify and treat.

Symptomatic hypertension

High blood pressure can also be due to diseases of a certain organ. It is characterized by high blood pressure in the kidney. Most often symptomatic hypertension develops diseases such as glomerulonephritis (infectious-allergic disease of the kidneys), and congenital renal vasoconstriction. Pyelonephritis and high pressure - phenomenon is characteristic, however, is long flowing inflammatory process can also lead to renal vasoconstriction. As a result, narrowing of kidney arteries begin to secrete the hormone renin, which contributes to a sharp narrowing of the blood vessels and persistent elevation of blood pressure, thus largely increases lower (diastolic pressure). High blood pressure and kidney - a very frequent combination, so the initial examination of the patient with high blood pressure in the first rule of kidney disease.

High blood pressure may also be in some diseases of the adrenal glands (eg, in tumors of the adrenal pheochromocytoma). The tumor in this case produces adrenaline, which contributes to a persistent increase in blood pressure.

High pressure in diabetes occurs least frequently. This contributes to atherosclerosis Atherosclerosis - when problems with blood vessels , Obesity, as well as increased blood viscosity typical of diabetes. Therefore, all recommended for diabetics to control not only blood sugar, but your blood pressure.

It is also characterized by high blood pressure during menopause - blood pressure rises because of hormonal disorders Hormonal disorders: causes and the most frequent disease . This blood pressure rarely rises steadily - for menopause longer characterized by significant differences in blood pressure, which is poorly tolerated by women. If you develop such complex as a climax and high blood pressure, women need adequate treatment with antihypertensive drugs.

High pressures may be transient, such as when significant stress. An example would be a high pressure after the operation, which is normalized as the recovery of the patient. But it is dangerous because it can cause bleeding, so postoperative anesthetists closely monitoring the pressure of the patients.

High blood pressure is also common colds, but in this case, be sure to call the doctor, because cold symptoms (eg, fever) can be confused with symptoms of incipient myocardial infarction - necrosis of cardiac muscle tissue may also be accompanied by fever.

Sometimes high blood pressure after a stroke, high blood pressure after a heart attack - to reduce it or not, the doctor decides, as a slight increase in blood pressure in this case may even be useful - it helps to improve the widening of collateral blood vessels that nourish the changing tissue site.

Portal hypertension

High pressure in the liver Liver disease: when the natural filter faltering   It does not develop in the entire circulatory system, but only in the portal vein is called portal hypertension. The cause of portal hypertension is usually cirrhosis or congenital anomaly of hepatic vessels. Effect on liver diseases pressure in the portal vein is characterized in that the blood flows into the liver of the heart not only directly, but also a bypass route through the other organs of the gastrointestinal tract. This leads to expansion of the veins in this area and the development of frequent bleeding. Stagnation of blood in the liver causes ascites (exudation of liquid part of blood in the abdominal cavity), which is often accompanied by varicose veins around the navel (head jellyfish).

High intraocular pressure

High eye pressure develops in violation of the outflow of intraocular fluid from the eye. The outflow of the fluid is broken or because of the blockade of access to outflow pathways or due to a change in the system outflow. This increases the pressure in the eyeball, it begins to compress the optic nerve, which gradually leads to the development of his first-degenerative metabolic processes, and then (in the long course of the disease) to full atrophy. At first sight it just reduced by narrowing the field of view, and then (atrophy) comes complete blindness. High eye pressure may cause seizures in patients with severe headaches and pains in the orbit.
