How do the kidney and vascular diseases contribute to hypertension?

Answer 1

Primarily, it's the other way around. Hypertension contributes to kidney and vascular diseases!

The kidneys autoregulate blood flow by controlling the diameter of tiny blood vessels going into and out of each of the microscopic urine-making structures called the "nephrons". When the pressure is high, these blood vessels become stiff from overgrowth of the muscle walls used to resist the flow. The nephrons themselves are damaged from pressure, and the organ's microstructure is slowly replaced by scar.

High blood pressure also represents a challenge to the rest of the bodily blood vessels, which become thickened in response to the pressure, and which are prone to shearing injuries to the lining. This is especially true when the lining is infiltrated with cholesterol in the form of atherosclerotic plaques. As the blood vessels become thickened and stiff, the pulsations of flow hammer away at the walls, creating things like aneurysms (balloon-like dilations prone to rupture) and blockages where the atherosclerotic plaques rupture and clot. This latter mechanism is commonly the cause of heart attack and stroke, as well as other end-organ damage.

There is one particular phenomenon, however, that DOES relate to your exact question. There is a condition known as renovascular hypertension, and this is one of the forms of high blood pressure that can be traced back to a treatable cause, and can be "cured" by an intervention. Most often, of course, hypertension is considered to be "essential hypertension" which means that there is no specific cause identified, and the hypertension itself needs to be treated because of the risks it poses to the patient's health.

Renovascular hypertension is a problem that occurs in those people who develop flow limiting atherosclerotic plaques in the arteries leading off to the kidneys. When this happens, the flow to the kidneys is substantially decreased, and the kidneys are "fooled" into thinking that there is a problem of flow throughout the body. The kidneys react to a situation that, if the arteries to the kidneys were normal, would probably represent low circulating blood volume. Basically, the kidneys are unable to tell the difference between low flow because the arteries are bad, and low flow because the patient lost a lot of blood from an injury.

The response from the kidney suffering low flow comes in the form of a hormone. This hormone is called "renin" and it has one job. Renin circulates in the blood and it turns a protein called "angiotensinogen" into "angiotensin 1". Angiotensin 1 is a hormone that increases the tension in blood vessels, but more importantly, it is a precursor to "angiontensin 2", which is what it its turned into immediately after passing through the lungs. Angiotensin 2 is one of the most powerful vaso-constricting hormones we have. It increases the blood pressure dramatically.

Renovascular hypertension can be treated by procedures which open up the narrowed blood vessel, but the key is that the problem needs to be recognized first! Sometimes people with this problem go unrecognized for long periods of time.

I hope that helps!

Hypertension can undoubtedly give a contribution to atherosclerosis (that's on the whole known as hardening of the arteries, it entails a buildup of ldl cholesterol within the coronary arteries inflicting them to slender), however there are lots of different elements as good corresponding to ldl cholesterol stage, smoking historical past, genetics, and practical age. I do not know of any relation among enviornmental exposures (rather than smoking) and atherosclerotic middle disorder. Now, that having been stated, relying on who honestly crammed out the loss of life certificates, it is almost always fine simply to disregard it, the ones matters are nugatory. They are on the whole crammed out by means of a health care professional who does not understand the sufferer good who's making his fine wager as to what could have triggered the loss of life, however does not understand. Also, there are on the whole different pressures, the reason of loss of life need to be authorized by means of the clinical examiner, that's usually complex (there are centain matters that are not able to be written, even though they are real) so on the whole atherosclerotic middle disorder is written while the health care professional are not able to determine some thing else, without reference to whether or not or now not it displays fact.

Answer 5

I couldn't just sit around and do nothing like my doctors suggested.

They didn't want me to do anything or to take herbs or herbal remedies, but I had to try something - they just wanted me to do dialysis!

This program allowed me to take control of my health. I went from Stage 4 to Stage 3 kidney disease.

It was easy to do and my BUN, creatinine and anemia are all in better ranges.

Answer 6

if the kidney is not functioning well,, it will retain water which will increase the intravascular volume and increases the pressure

hypertension causes cascular disease and endothelial (cells lining the vessels) damage which will contribute to atherosclerotic plaque formation...
