    Renal hypertension: life on a powder kidneyWhat does the kidney?

    In inexperienced in matters of medical patientsThis question arises more often. For Professionals renal hypertension development mechanism is obvious: because the pressure - it is a derivative of the interdependent work of the heart, kidney and vascular tone. In the process of evolution of kidney took over the function of the pressure regulator. Otherwise they would not be able to filter comes before us in the water body.

    If for any reason, this mechanismIt is broken and the pressure drops in blood ejected renin - specific substance is converted into angiotensin, which has vasoconstrictor activity and stimulates the production of aldosterone - adrenal hormones in the body retarding sodium and water. There is a life-threatening situation in which the level of circulating blood does not match the volume of the vascular bed.

    What is different from the usual renal hypertension?

    In normal (heart), hypertension pressure jumps in response to emotional or physical stress. When kidney - high blood pressure is kept constant.

    diastolic - - pressure As a rule, the lower increases in renal hypertension. For an adult human common indicators blood pressure 120/80 mm Hg up. Art. And it is considered acceptable rise to 140/90. Anything above - the norm abroad.

    Especially cautious lately doctorsbelong to the so-called mild hypertension, in which the pressure level of 140-159 / 90-99 mm Hg. Art. Do doctors, it is considered the most insidious. The man in this case is quite normal to feel and not to suspect that stands at the point of no return. At one time it was thought that such a slight pressure rise, and it is not necessary to treat. Until it became clear that he was the first instigator of cerebral strokes.

    Who is at risk?

    Renal hypertension is often chooses tosacrifice the young and able-bodied. Most of all - men. What, according to experts, it is a scientific explanation: the representatives of a strong half of mankind has always had a greater propensity to hypertension. Unlike women men have more body mass, and hence the volume of the vascular bed with circulating it, which creates a "favorable" conditions for a higher pressure level.

    The dangerous renal hypertension?

    Renal hypertensive patients not to be envied. In addition to cardiac and renal failure, and cerebrovascular accidents regular increase in diastolic pressure is fraught with retinal hemorrhage, severe lesions of arteries. The "worst" hypertensive change properties of the blood (it becomes more viscous), disturbed lipid metabolism, blood vessels, as corrosion, affected with atherosclerosis lose their elasticity, and require a lot of effort all the heart. People with high blood pressure the heart - a real "lifter".

    Renal hypertension: life on a powder kidneyIs there salvation?

    Until recently, renal hypertension havetreated handfuls of drugs that do not always lead to the desired result. Contrary to popular belief (that, say, hypertension treated successfully), hypertension with renal component of a truly positive result physicians can be achieved only in 4% of cases. The reason - the complexity of the mechanism of regulation of renal pressure. And the mass of adverse reactions to drugs, lowering it.

    More recently, in hypertensive patients there is hope -a unique and very effective method of treating hypertension, allowing operation without anesthesia, and change the direction of blood flow and reduce the amount of hormones, provoking the rise of blood pressure, and vascular spasm. However, this technique is not so new. Know-how is the subject of our pride of Urology, was discovered and patented by thirteen years ago.

    The essence of the method lies in the uniquepainless puncture of the femoral vein through which a miniature spiral inserted under X-ray control central venous adrenal coated with Teflon. Thanks to this manipulation changes in the adrenal glands blood flow is reset excessively produced by aldosterone and other stress hormones in the liver, where they are destroyed, eliminating the hypertensive patient suffering from for years to come.

    By the way ...

    The cause of renal hypertension can be anykidney disease: narrowing of the renal artery (due to atherosclerosis or congenital anomalies of vessels), polycystic (a hereditary disease in which kidney tissue is compressed), nephropathy (a consequence of diabetes) and even pyelonephritis, causing major changes in the structure of the kidney itself.

    Instructions for hypertensive

  • Monitor your pressure. Especially in adverse meteorological parameters on days hypertensive which are known to be particularly sensitive. Before measure the pressure10-15 minutes, sit quietly. Make several measurements (preferably on both hands) at rest, in moments of stress and after. Do not try to maintain the usual way nyzvaemoe "working" pressure for you, if it is outside the normal range. According to Michael Koryakina, each millimeter rise in diastolic (bottom) pressure above the 100 - stricken from the year of your life.

  • Be on the lookout! Impending attack of renal hypertension is usually preceded by dizziness, headache, flashing "flies" before the eyes, weakness in the limbs, nosebleeds, pressing pain in the heart.

  • If you regularly celebrate at thesesymptoms, do not delay. Run to the doctor! First of all, find out whether your hypertension in renal components: hand over a blood on hormones, perform magnetic resonance imaging of the adrenal glands and, if necessary - and angiography of the renal arteries.

  • Try to normalize body weight. Losing every extra 5 kg reduces the pressure to several divisions. Reasonable exercise and low-calorie diet - the best option.

  • Wean dosalivat food. For hypertensive salt - the number one enemy. It leads to fluid retention and increases the already high vascular tone.

  • If you are a smoker, then please be courage andtry to gradually give up smoking, as well Moderate consumption of alcohol. The most that is allowed to take on hypertensive chest - 60 ml of spirits and 200 grams of dry wine a week. The same applies to coffee and strong tea. Limit the consumption of at least up to a cup a day.
