Is Renal Hypertension Life-Threatening

Is renal hypertension life-threatening? To know well about this question, let’s make clear what renal hypertension is and how kidney disease cause renal hypertension.

What is renal hypertension?

Renal hypertension refers to high blood pressure that occurs due to impairment of renal parenchymas and renal arteries. It accounts for 5%-10% of Hypertension in adults.

How does kidney disease cause renal hypertension?

Renal hypertension is a common symptom or complication of kidney disease and generally caused in the following two ways:

1. Impairment of renal parenchyma makes kidneys unable in discharging excess fluid and sodium. Large amounts of fluid and sodium stay in blood vessels, leading to expand of blood volume,which can cause high blood pressure.

2. Kidney damages stimulate periglomerular cells to secrete lots of renin, which can increase the activity of angiotensin and cause shrinkage of blood vessels. High blood pressure refers to high impact of blood on vascular wall and when blood vessels are shrunk, pressure on vascular wall increase and high blood pressure occurs.

Is renal hypertension life-threatening?

High blood pressure is a common illness in our daily life, so it is usually not treated seriously. However, for kidney disease patients with renal hypertension, it is of great importance for them to bring their blood pressure into normal range due to its following bad effects:

1. Renal hypertension can accelerate illness progression

Although renal hypertension occurs as a consequence of kidney damages, in turn it further damages kidney and aggravates kidney condition.

2. Renal hypertension can increase the incidence of cardiovascular disease

Cardiovascular disease is the leading cause of death among kidney failure patients. High blood pressure increases burden on heart and for kidney disease patients, if this condition lasts for a long time, their risk for cardiovascular disease will be increased greatly.

Renal hypertension cause no death immediately, but it shorts kidney disease patients’ life in many other ways, so a timely and effective treatment is always urgently needed for kidney disease patients to control their illness condition well.
