The survival time for renal hypertension is related to the type and extent of the disease and individual circumstances and cannot be generalized. Renal hypertension is a common type of disease secondary to hypertension and can be caused by various types of nephritis, renal vascular stenosis, and other renal pathologies. The main mechanism is due to various renal diseases causing reduced glomerular filtration capacity, water and sodium retention, which causes an increase in body volume and leads to an increase in blood pressure; in addition, it can also abnormally activate the renin-angiotensin-aldosterone system, causing abnormal vasoconstriction and leading to an increase in blood pressure. If the primary disease is actively treated at this time and various symptomatic treatment measures are taken, blood pressure will naturally decrease and will not affect the life of the patient. However, if the primary disease develops further and combines with the failure of the heart, brain, kidneys and other important organs, it may be life-threatening. It is recommended that patients with renal hypertension should actively consult a nephrologist to treat the primary disease in a timely manner. In addition, patients need to pay attention to rest and reasonable diet.
