Secondary hypertension is the cause of what

1. Renal hypertension Renal hypertension is the most common secondary hypertension, which is due to kidney or renal vascular lesions caused substantial hypertension. Responsible for the supply of renal artery blood - renal artery stenosis, will lead to renal ischemia, which is one of the major clinical manifestations of hypertension. Common cause high blood renal parenchymal lesions including glomerulonephritis, chronic renal pelvis nephritis, kidney nuclear, systemic diseases and systemic lupus erythematosus kidney damage. Have kidney disease patients in addition to the substantive clinical hypertension, in the regular inspection of urine, can be found protein, such as abnormal red blood cells or leukocytes. 2. Adrenal diseases caused by hypertension Thousands of small renal glands - the adrenal hyperplasia or tumors cause secondary hypertension is also an important reason. Outside the adrenal cortex, with a tendon transfer. Adrenal cortex hyperplasia or tumors mainly caused both diseases January 1 Cushing syndrome and primary aldosteronism. Cushing's syndrome patients suffering from the excessive secretion of adrenal cortex known as a glucocorticoid substances. In addition, patients with hypertension often concentric obesity, limbs, muscle wasting, might face one month in office (that one-month-face, red (blood more qualitative), abdomen, and thigh in purple stripes, acne skin, body hair, enlargement female menstrual disorders and different levels of masculinity. other diseases because of long-term use of prednisone, dexamethasone-treated patients, and other drugs will emerge in a group of the clinical manifestations. Cushing's syndrome characteristic clinical manifestations, the general and it is not difficult to distinguish primary hypertension. In primary aldosteronism, adrenocorticotropic hormone aldosterone is too much material. Aldosterone excess water and the large number of body sodium retention due to potassium in the urine from increased. Apart from high blood pressure patients, check blood will discover high hyponatremia and hypokalemia, check urine, potassium content in urine increased, and from the urine from the less than sodium intake of sodium in the diet. Hypokalemia and patients due to a weakness, muscle weakness, paralysis and intermittent seizures. For nocturnal enuresis more common symptoms. Cause secondary hypertension disease of the adrenal medulla for pheochromocytoma. Adrenomedullin intermittent or persistent excessive secretion of adrenaline and noradrenaline. Both substances can speed up the heart rate, blood vessels to contract, so that the patient's blood pressure or continuous seizures increased, the three common symptoms of the onset of severe headache, sweating, palpitation. But they may not be in a three patients at the same time. Other symptoms include looking pale, nausea, abdominal pain, breathing difficulties. 3. Pregnancy induced hypertension (PIH) Pregnant women generally have higher blood pressure three situations: ① before pregnancy have primary or secondary hypertension, as pregnancy with chronic hypertension; ② hypertension in pregnancy, childbirth within three months after the restoration of normal blood pressure, pregnancy-induced hypertension; ③ hypertension before pregnancy has been in existence; after pregnancy increase blood pressure, high blood that situation before pregnancy and pregnancy-induced hypertension. PIH not normally difficult diagnosis. The levy pregnant patients with edema, and examine a number of urinary protein, that is, proteinuria. 4. Hypertension The increased blood pressure caused vascular lesions are common coarctation of the aorta, the main artery inflammation and atherosclerosis, etc.. Coarctation of the aorta patient's blood pressure increased significantly upper, lower blood pressure and lower limbs, and even without blood pressure. Aortoarteritis frequently in young women, which often involved physical side of the artery, blood pressure can be found when the two upper blood pressure significantly different, more unusual increase in the side, the other side of the low, and even could not be determined. Aortoarteritis can also affect the renal artery, renal artery stenosis. Elderly common atherosclerosis can cause upper two blood pressure significantly different.
