Secondary common cause of hypertension

1. Renal Hypertension: renal hypertension is the most common secondary hypertension, which is due to kidney or renal vascular lesions caused substantial hypertension. The former is mostly for congenital renal artery stenosis is the main cause of younger patients, blood pressure increased significantly, the effect of various types of antihypertensive agents poor latter mainly due to chronic glomerulonephritis, chronic pyelonephritis, diabetes kidney disease, connective tissue diseases, such as polycystic kidney disease caused urine test patients often can be found protein, such as abnormal red blood cells or leukocytes. 2. Endocrine hypertension: The main diseases caused by the adrenal gland, a common Cushing's disease, primary aldosteronism and pheochromocytoma. Cushing patients often concentric obesity, limbs, muscle wasting, might face one month after red, abdomen, and thigh in purple stripes, acne skin, body hair, thickening, female menstrual disorders and varying degrees of masculine . Patients with primary aldosteronism tests will discover high hyponatremia and hypokalemia, and potassium content in urine increased, the patient appeared fatigue, muscle weakness, paralysis and intermittent seizures, and more nocturnal enuresis. Pheochromocytoma blood pressure for patients with paroxysmal or sustained higher, common to the three main symptoms of the onset of severe headache, sweating, palpitation, and other symptoms, including looking pale, nausea, abdominal pain, breathing difficulties. 3.

More occurred in the body squat, anemia, a family history of hypertension or female, cold climate Zhouranbian. 4. Hypertension: blood pressure caused the vascular lesions, a 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, unusual increase in the side, the other side could not be determined even lower. Aortoarteritis can also affect the renal artery, renal artery stenosis. Elderly common atherosclerosis, blood pressure can cause upper two distinctly different. 5. Drug-induced hypertension: there are many drugs can cause high blood pressure, patients with long-term use can cause hypertension, can be a serious heart and kidney complications, adverse consequences. A hormone drugs, such as cortisone, prednisone, testosterone propionate, nandrolone styrene-acrylic acid; contraceptives; licorice preparations; adrenergic drugs, such as epinephrine, norepinephrine, epinephrine to drugs (such as ephedrine hydrochloride), and benzene epinephrine, isoproterenol; other drugs such as indomethacin, Ritalin, thyroxine agents, such as sodium bicarbonate.
