How does high blood pressure affect the kidneys?




A health care provider diagnoses high blood pressure with multiple blood pressure tests—often repeated over several visits to a health care provider’s office—show that a systolic blood pressure is consistently above 140 or a diastolic blood pressure is consistently above 90. Health care providers measure blood pressure with a blood pressure cuff. Individuals can also buy blood pressure cuffs at discount chain stores and drugstores to observe their blood pressure at home.  

High blood pressure will harm blood vessels within the kidneys, reducing their ability to work properly. When the force of blood flow is high, blood vessels stretch thus blood flows more simply. Eventually, this stretching scars and weakens blood vessels throughout the body, together those within the kidneys. If the kidneys’ blood vessels are damaged, they will stop removing wastes and additional fluid from the body. Extra fluid in the blood vessels might raise blood pressure even more, making a dangerous cycle.

Renal hypertension usually causes no symptoms. The narrowing in the arteries can't be felt. Unless it's dangerously high, high blood pressure causes no symptoms, either. Symptoms of severely elevated blood pressure include:
·         Headache
·         Confusion
·         Blurry or double vision
·         Bloody (pink-colored) urine
·         Nosebleed

Protect your kidneys by managing your blood pressure
Controlling your pressure is an crucial way to reduce kidney disease, and to reduce your risk of heart condition and stroke. Your doctor will need to confirm that blood pressure is lower than 140/90 mmHg, and in some cases as low as 130/80 mmHg.
ACE inhibitors or angiotensin receptor blockers are usually primary alternative of blood pressure medicine for someone with kidney disease. This is because they help protect the kidneys against further damage. If these medicines do not lower your blood pressure enough then other blood pressure medicines can be used.
If you have diabetes as well as high blood pressure, it is very necessary to keep this controlled. Diabetes can cause serious harm to your kidneys if it is not treated properly.

Hypertension, or high blood pressure, is a leading contributor to heart disease and stroke, two diseases which together account for 1 in 5 premature deaths (under age 65). In the past decade, the prevalence of hypertension has increased by 11%. Today, over 1 in 4 adults (estimated 1.8 million people) report having hypertension. Diagnosing and treating high blood pressure with lifestyle counselling and with the right medications can prevent hospital admissions, heart attacks, strokes, heart failure, and premature death. Although genetics plays a role, it is clear that lifestyle and diet are a major component. It is often a silent manifestation of underlying untreated medical, behavioural or social conditions. Education, periodic early screening and lifestyle modification significantly delay and even prevent the onset of the disease. Realizing the importance to explore latest research advancements in Hypertension treatment, Cardiology Conference series is organizing the 5 th Inter

Can Renal Denervation control Resistant Hypertension??

Can Renal Denervation control Resistant Hypertension?? It is well known fact that if hypertension is not treated on time then it can turn into resistant hypertension. Resistant hypertension refers to the condition where blood pressure remains high even after taking three antihypertensive agents of different classes. After various studies it has been seen that renal denervation can lower the blood pressure in hypertensive Patients who are not taking medications. Renal denervation is less painful, endovascular catheter based procedure which uses radio frequency or ultrasound ablation. This procedure removes the nerves in the wall of renal artery by radio frequency pulses or ultrasound. Due to this there is reduction of afferent and efferent activity to the kidney and as a result blood pressure can be reduced. Basically renal denervation provides energy to the kidney nerves and regulates the blood pressure. Studies were conducted to check the efficacy of the t

Uric acid level responsible for increase in blood pressure

Uric acid level responsible for increase in blood pressure High Blood Pressure also known as Hypertension , is one of the most common and long-term medical problem faced by people today. High blood pressure refers to the persistent elevation of blood pressure in arteries. It can be classified as Primary and Secondary Hypertension. Hypertension has now become one of the most common cardiovascular diseases. The chances of getting hypertension becomes higher with age, which results in increase mortality rate due to events such as heart failure , myocardial infraction , stroke etc. The level of uric acid plays a major role in controlling blood pressure. Various studies have found uric acid’s association with hypertension . Uric acid is waste product which is the result of food metabolism. The amount of uric acid in our body should be maintained. When the amount of uric acid in our body builds up then it can lead to increase in blood pressure. Too much increase in level of u
