How Hypertension relates to renal failure? How hypotension relates to renal failure?

Question

Thank you for your help

Answer 1

Hypertension may cause renal failure due to its causal role in chronic vascular damage, which produces sclerosis of the arteries, and over time reduces blood supply to the kidneys -- this will ultimately result in focal ischemia and necrosis (i.e. dead renal tissue) that will over time involve enough of the kidneys to cause renal failure

Hypotension may cause renal failure due to extremely low blood perfusion of the kidneys, infarcting them (like a heart attack, or stroke, but damaging the kidneys instead) -- the renal tissue is then dead, and thus non-functional.

Answer 2

Hypertension has many causes, among them are renal diseases. So some types of renal failure can cause hypertension. Hypertension can also cause renal failure as well as damaging many other organs. Hypotension can cause renal failure in the setting that there is massive uncontrolled hemmorhage. Under those circumstances, the renal artery will contract to send blood to more vital organs. If this continues for enough time there will be renal failure. However, chronic low grade hypotension is not considered a cause of renal failure.

Ehm..
Many times people may not experience any symptoms until their kidney disease is well advanced. Early signs that the kidneys may be diseased include blood or protein in the urine or elevated blood pressure readings. If you want to know how to overcome kidney disease
