Nephrogenic hypertension ( renal pressure) - Causes, Symptoms and Treatment .MF .

August 12, 2017 17:52 | Diseases Of The Heart And Blood Vessels

nephrogenic hypertension (or as it is called patients - "renal" pressure) - it is a systematic increase in blood pressure due to kidney disease.On the mechanism of its development nephrogenic hypertension is renovascular and parenchymal.The first disrupted the functioning of the body vessel, while the second - direct its tissue.

reasons nephrogenic hypertension

Regardless of the type of renal hypertension, the disease remains a single mechanism.In case of violation of organ function increases the production of special hormones - renin, which is responsible for the tone of the vascular wall.By increasing the tone of arteries, renin narrows the lumen of the latter, thus increasing blood pressure.

immediate cause of renovascular hypertension is the pathology of renal vessels.Firstly, it can be congenital, such as the renal artery wall hyperplasia, coarctation of the aorta or renal artery aneurysm.In addition, enhance the blood pressure and may be acquired factors.Atherosclerosis of renal vessels, ren

al artery embolism, stenosis of the vessel sclerosing paranephritis, compression of the renal artery from the outside - the disease, which can also be causes of nephrogenic hypertension.

As parenchymal hypertension , that its causes may be both congenital and acquired factors.Among developmental abnormalities affecting blood pressure, it should be noted hypoplasia and a doubling of the kidneys.In addition, the cause of the high-pressure variant can be congenital renal cysts.

Among the acquired causes of nephrogenic hypertension largest share inflammatory kidney disease.Acute and chronic glomerulonephritis and pyelonephritis are the most common causes of high blood pressure due to the high concentration of renin in the blood.

mechanism of development of nephrogenic hypertension

diagnosis of renal hypertension

diagnose renal arterial hypertension is very difficult, since it is necessary to exclude almost a dozen diseases, which can also lead to high blood pressure.

First, to suggest a possible diagnosis requires periodic monitoring of blood pressure at home with a tonometer.However, if during one month marked increase in blood pressure above 140/90 mm Hg, while exhibiting a diagnosis of hypertension.If in the course of further investigation fails to reveal kidney abnormalities, hypertension is classified as nephrogenic.

This is done by a list of studies in the first place in which there is a general analysis of blood and urine.Often, in inflammatory kidney disease can be revealed increased number of leukocytes in the blood and urine.In addition, in glomerulonephritis in the urine may experience a small amount of red blood cells.

next diagnostic step is an ultrasound of the kidneys, in which you can identify malformations, cysts or tumors of the renal parenchyma.

ultrasound.Hydronephrosis as cause of renal hypertension

to determine kidney function performed radioisotope renografiya or excretory urography.These methods do not give an idea of ​​the body structure and its functionality.

If such screening can not determine the pathology of kidneys, then performed laboratory testing to determine the renin level in the blood.This diagnostic method makes it possible to accurately judge whether the kidney disease effect on blood pressure or not.

Symptoms of nephrogenic hypertension

According to its clinical course nephrogenic hypertension is virtually identical to hypertension, although there are some characteristics that allow all the same set of renal pathology.

There are two variants of the disease: benign and malignant.In embodiment benign hypertension renal arterial pressure is usually increased steadily and does not tend to decrease.Patients complain of headaches, weakness, dizziness, fatigue, shortness of breath, discomfort and pain in the heart, and the heart.

malignant form of nephrogenic arterial hypertension is characterized by increased mainly diastolic pressure.Rapidly progressive process will soon cause blurred vision, which is called hypertensive retinopathy.Patients with such a variant of the disease complain of chronic headaches, especially in the neck, nausea, vomiting and dizziness.

analyzing the symptoms of the disease, it can be noted that they are virtually indistinguishable from the normal signs of hypertension.But in some cases, due to violations of renal blood flow, patients may experience pain in the lumbar region, which suggests the presence of urological diseases.

If a patient has at least one of the above symptoms should immediately consult a urologist or a therapist who will be able to assign the correct tests and studies to confirm or refute the diagnosis of urological diseases.

Treatment of renal hypertension

The treatment of this disease must involve at least two doctors - a urologist and internist.If the first task - to cope with kidney disease, the latter is obliged to normalize blood pressure.Treatment

kidney disease depends on its type.For example, if the patient suffers from kidney tumor or cyst, in this situation, simply can not do without surgery, during which the need to remove the neoplasm.

When inflammation of the renal pelvis or parenchyma appointed antibiotics, such as ceftriaxone and gatifloxacin.They can be purchased over the counter without a doctor's prescription, but do not need, as these drugs have multiple side effects, which should be monitored technician.

second direction in the treatment of renal hypertension is blood pressure normalization.It can produce any antihypertensive drugs, but the pathogenesis caused by ACE inhibitors are the only factor.Representatives of this group are the drugs captopril, enalapril and fozzinopril.They were released on prescription in almost any drugstore.The course of treatment depends on the blood pressure indicators to be normalized to the figures below 140/90 mmHg.

Feeding habits and lifestyle with nephrogenic hypertension

When hypertension, regardless of the cause, is assigned to a dietary food with a limited number of edible salt in the diet.In addition, it is necessary to exclude sour, fried, peppered and spicy dishes, which in addition to the fact that increase blood pressure, adversely affect renal function.Absolutely unacceptable for high blood pressure is considered to be drinking coffee, strong tea and alcohol.

As for lifestyle, it is necessary to remember that in hypertension, including nephrogenic, to avoid heavy physical exertion, which can help improve vascular tone and consequently the blood pressure.

rehabilitation after illness

Patients with renal arterial hypertension are recommended courses of sanatorium treatment in sanatoriums and the pine forest air.Well suited for this purpose resorts Chmielnik, who specializes in treating diseases of the cardiovascular system.

addition, developed a set of exercises for physical therapy, which help to reduce the tone of blood vessels and lower blood pressure.However, you should consult with a doctor-physiotherapist for him to find the right exercise before starting these procedures.

Treatment of renal hypertension folk remedies

For the treatment of hypertension, traditional medicine is a huge amount of funds.Some of them have a fairly powerful hypotensive effect, which in some cases gives positive results.The main mistake of the national treatment of nephrogenic hypertension is that it does not act on the cause of the disease, and lowers blood pressure symptomatically.In this case, the disease continues to progress, and after discontinuation of the infusions of herbs or pressure increases even more.

Thus, the use of folk remedies is permissible only in the case when finally revealed the cause of the disease, and it does not lie in renal pathology.

Complications of renal hypertension

With constantly high blood pressure begin to suffer the so-called target organs.First of all disrupted vascular system of the eye, which leads to a hypertensive retinopathy.Patients complain of progressive visual impairment, which is irreversible.

Besides the eye, due to high blood pressure begins to break the brain and heart muscle function.Subsequently, it could face a stroke or heart attack.

In addition, high blood pressure begins to suffer cardiovascular system itself kidneys.Thus, a "vicious circle", which opens only after renal function completely fails.

prevention of nephrogenic hypertension

Prevention of this disease is based on the prevention of kidney disease, which holds to the above symptom.

Firstly, the need to guard against hypothermia, both general and local hypothermia lumbar region.This can lead to renal inflammatory diseases that are accompanied by increases in blood pressure.

also in the use of any medication you need to pay attention to expiry dates and side effects.People who in the past had problems with urinary organs, antibiotics should only be used after consulting a specialist, and a whole list of laboratory studies.
