How is kidney function related to blood pressure? – Dr. Pallavi Patri

We all know that kidney disease affects kidney function and causes an accumulation of toxins in the blood. Kidney Patients need to undergo dialysis or kidney transplant to excrete those toxins from blood vessels.

CRCHUM director Dr. Vincent Poitout reported that We identified molecular mechanisms that may be responsible for the increase in blood glucose levels in patients with non-diabetic kidney disease. Our observations in mice samples and in human samples show that the disease can cause secondary diabetes, from his research. He explained that chronic kidney patients without diabetes start to develop secondary diabetes because of a specific toxin in the bloodstream.

Can High Blood Pressure Cause Kidney Disease

Kidneys use blood vessels to clean your blood of wastes, toxins and excess fluid. High blood pressure means that high pressure is consistently being exerted against the walls of arteries throughout the body, which can damage blood vessels over time. Damage to blood vessels, including the hardening and narrowing of arteries around the kidneys, can prevent your kidneys from cleaning bloodeventually leading to kidney disease.

Kidney disease or kidney failure due to high blood pressure may take years to develop. If you are diagnosed with kidney disease, it’s important to know that there are things you can do to manage CKD and thrive.

Over Time High Blood Pressure Harms Renal Blood Vessels

The nephrons in the kidneys are supplied with a dense network of blood vessels, and high volumes of blood flow through them. Over time, uncontrolled high blood pressure can cause arteries around the kidneys to narrow, weaken or harden. These damaged arteries are not able to deliver enough blood to the kidney tissue.

  • Damaged kidney arteries do not filter blood well. Kidneys have small, finger-like nephrons that filter your blood. Each nephron receives its blood supply through tiny hair-like capillaries, the smallest of all blood vessels. When the arteries become damaged, the nephrons do not receive the essential oxygen and nutrients and the kidneys lose their ability to filter blood and regulate the fluid, hormones, acids and salts in the body.
  • Damaged kidneys fail to regulate blood pressure. Healthy kidneys produce a hormone called aldosterone to help the body regulate blood pressure. Kidney damage and uncontrolled high blood pressure each contribute to a negative spiral. As more arteries become blocked and stop functioning, the kidneys eventually fail.

How Does Lower Blood Pressure Cause Kidney Failure

When your blood pressure decreases it indicates that there is a change in blood flow throughout the body. A change in blood flow can cause you to experience serious problems with your kidneys. If the blood flow is not corrected, it could result in serious, potentially fatal, problems.

The kidneys are often the first organs to experience problems as a result of low blood pressure. The problems occur because there is a dramatic decrease in blood flow to the kidneys. If the kidneys dont have access to the right amount of blood, they are unable to properly filter the blood or receive enough oxygen to function. Over time these problems from the lower blood pressure result in the kidneys slowly shutting down.

    Treating High Blood Pressure When You Have Kidney Disease

    High blood pressure, or hypertension, is one of the leading causes of kidney disease. Many people with high blood pressure need medicine to help lower blood pressure, which also helps to slow the progression of kidney disease. Two groups of medicines that lower blood pressure are:

    • Angiotensin-converting enzyme inhibitorsAngiotensin II is a chemical in the body that narrows blood vessels by making the muscles around the blood vessels contract. It creates a chemical called angiotensin I. ACE inhibitors prevent angiotensin I from creating angiotensin II. This helps the muscles around the blood vessels relax and enlarges the blood vessels, which reduces blood pressure.
    • Angiotensin receptor blockers ARBs block angiotensin II from causing the muscles around the blood vessels to contract and make the blood vessels smaller. ARBs protect the blood vessels from the effects of angiotensin II so that blood pressure stays in a safe range.

    ACE inhibitors and ARBs lower blood pressure, which also helps to slow kidney damage. Some people may need to take a combination of two or more blood pressure medicines to stay below 130/80.

    Protein Or Blood In The Urine

    Urinalysis or urine testing is used to look for abnormalities such as an excess amount of protein, blood, pus, bacteria or sugar. A urine test can help to detect a variety of kidney and urinary tract disorders, including chronic kidney disease, diabetes, bladder infections and kidney stones. A trace of one type of protein, albumin in urine is an early sign of chronic kidney disease. Persistent amounts of albumin and other proteins in the urine indicate kidney damage. The presence of albumin is also a risk factor for cardiovascular events and death.

    Elevated Blood Pressure And Risk Of End

    It had been known since the early days of Franz Volhard and Arthur Fishberg that renal disease and renal failure occur commonly in hypertensive patients. In the study of Perera , at a time when antihypertensive medication had not yet become available, a large proportion of patients with essential hypertension wound up in renal failure. This was later ascribed to the occurrence of malignant hypertension. With the advent of effective antihypertensive medication, malignant hypertension has become much rarer. In relatively short-term trials that clearly documented the cardiovascular benefit from antihypertensive medication, few if any cases with renal failure were observed. This led to an as yet unresolved dilemma.

    There are authors who made strong statements such as: there are no reported cases of benign essential hypertensive patients with normal serum creatinine levels and no proteinuria who subsequently went on to develop renal failure . On the other hand, in the US and elsewhere, but with remarkable differences between countries , a high proportion of cases reaching end-stage renal disease with hypertension and a nondiagnostic clinical course are given the diagnosis of hypertensive nephropathy in the absence of renal biopsy and other more in-depth investigations.

    How Is It Treated

    Understanding High Blood Pressure And Kidney Failure

    If you have high blood pressure, your doctor will give you a blood pressure goal. Your goal will be based on your health.

    You can help lower your blood pressure by making healthy changes in your lifestyle. If those lifestyle changes donât work well enough, you may also need to take pills. Either way, you will need to control your high blood pressure throughout your life.

    Treatment depends on how high your blood pressure is, whether you have other health problems such as diabetes, and whether any organs have already been damaged. Your doctor will also consider how likely you are to develop other diseases, especially heart disease.

    Most people take more than one pill for high blood pressure. Work with your doctor to find the right pill or combination of pills that will cause the fewest side effects.

    What Causes High Blood Pressure

    High blood pressure usually develops over time. It can happen because of unhealthy lifestyle choices, such as not getting enough regular physical activity. Certain health conditions, such as diabetes and having obesity, can also increase the risk for developing high blood pressure. High blood pressure can also happen during pregnancy.

    You can manage your blood pressure to lower your risk for serious health problems that may affect your heart, brain, kidneys, and eyes.

    What Are The Symptoms

    High blood pressure doesnât usually cause symptoms. Most people donât know they have it until they go to the doctor for some other reason.

    Very high blood pressure can cause severe headaches and vision problems. These symptoms can also be caused by dangerously high blood pressure called malignant high blood pressure. It may also be called a hypertensive crisis or hypertensive emergency. Malignant high blood pressure is a medical emergency.

    How Will I Know Whether I Have Kidney Damage

    Kidney damage, like hypertension, can be unnoticeable and detected only through medical tests. Blood tests will show whether your kidneys are removing wastes efficiently. Your doctor should order tests to measure your serum creatinine. Having too much creatinine in your blood is a sign that you have kidney damage. The doctor should use the serum creatinine to estimate the main kidney function called glomerular filtration rate, or GFR. Another sign is proteinuria, or protein in your urine. Proteinuria has also been shown to be associated with heart disease and damaged blood vessels. .)

    Eat Less Meat More Plants

    A plant-based diet is an easy way to increase fiber and reduce the amount of sodium and unhealthy saturated and trans fat you take in from dairy foods and meat. Increase the number of fruits, vegetables, leafy greens, and whole grains youre eating. Instead of red meat, opt for healthier lean proteins like fish, poultry, or tofu.

    What Should I Avoid Eating If I Have High Blood Pressure Or Kidney Disease

    If you have kidney disease, avoid foods and beverages that are high in sodium.

    Additional steps you can take to meet your blood pressure goals may include eating heart-healthy and low-sodium meals, quitting smoking, being active, getting enough sleep, and taking your medicines as prescribed. You should also limit alcoholic drinksno more than two per day for men and one per day for womenbecause consuming too many alcoholic beverages raises blood pressure.

    In addition, a health care professional may recommend that you eat moderate or reduced amounts of protein.

    Proteins break down into waste products that the kidneys filter from the blood. Eating more protein than your body needs may burden your kidneys and cause kidney function to decline faster. However, eating too little protein may lead to malnutrition, a condition that occurs when the body does not get enough nutrients.

    If you have kidney disease and are on a restricted protein diet, a health care professional will use blood tests to monitor your nutrient levels.

    How High Blood Pressure Can Damage Kidneys

    High blood pressure the second leading cause of CKD is an increase in the force of blood as it flows through your blood vessels. Over time, that force can damage the tiny vessels in the nephrons, just as it can damage blood vessels throughout the body.

    The vessels in the kidney are delicate, explains Dr. Leisman. Imagine two hoses: one is high pressure and one is low pressure. Both have water coming out, but the water coming from the high-pressure hose, over time, can lead to damage.

    Leisman notes that treating high blood pressure is one of the cornerstones of preventing or slowing kidney damage. In fact, some of the most common drugs used to lower blood pressure are considered a standard treatment for CKD.

    What Is Normal Blood Pressure

    Take the Pressure Off: Your Kidneys and Your Health

    Blood pressure normally varies a lot, from minute to minute and even from one breath to the next. It is usually lower at night, and goes up with exercise and other forms of stress . It also varies around the body.

    For most purposes, it is best to measure blood pressure in the upper arm, at heart level, with the person sitting comfortably, not talking, having rested for at least five minutes and avoided cigarettes and caffeine for at least 30 minutes. Measured like this, a normal adults blood pressure is around 120/80 mm Hg.

    Blood pressure is often measured in a rush in outpatient clinics, without much time for rest, and often at a time of increased anxiety. Measurements taken like this shouldnt be used as the sole basis for deciding on treatment. Repeated measurements at home or ambulatory blood pressure measurements give a much better idea.

    • Your blood pressure is considered to be high if your blood pressure is 140/90mmHg or above, and your average daytime ambulatory or home blood pressure is 135/85mmHg or above.
    • The higher your resting blood pressure, the higher your risk of heart disease, stroke, and progressive kidney damage.

    There is often no obvious cause for hypertension but some groups, for example people from minority ethnic groups are more prone to developing high blood pressure.

    What Procedures May Help Treat Renal Hypertension

    Angioplasty with stenting is an invasive procedure that helps blood flow more freely through the artery to the kidney. It is an option for those who have:

    • Severe narrowing of the renal artery.
    • Blood pressure that cannot be controlled with medicines.
    • Kidneys that are not working well and are rapidly becoming worse.

    In an angioplasty, a healthcare provider inserts a catheter into a small puncture over an artery in the arm or groin. This catheter carries a tiny inflatable balloon with it to the blocked area. There, the balloon is inflated and deflated several times to flatten the plaque against the artery walls, widening the vessel. After the procedure, the balloon and catheter are removed from the body. Stenting is usually needed in addition to angioplasty.

    With stenting, a tiny mesh tube, called a stent, is inserted by the catheter. Just like the balloon in an angioplasty, the stent is guided to the narrowed area of the renal artery and placed to provide support, keeping the artery open. The stent is left in place permanently.

    What Is Chronic Kidney Disease

    The kidneys are a pair of bean-shaped internal organs responsible for removing waste products from the body. When the kidneys cant remove the waste from the blood efficiently, that condition is called kidney disease. There are several causes and types of kidney diseases. Kidney diseases are classified into two major types.

    • Acute Kidney Disease
    • Chronic Kidney Disease

    There are several causes for acute kidney diseases that can be developed within several days, and they can be fatal. AKD can be reversed in several situations.

    Several other conditions cause chronic kidney diseases unfortunately, there is no cure for CKD. It can be caused by diabetes, blood pressure, heart disease, unhealthy food consumption for a long time, and genetic reasons. CKD patients can extend their lifespan using proper medication, diet, yoga, physical activity, dialysis, and kidney transplant. But the damaged part cannot be healed or recovered. But that doesnt mean you cant lead a happy life. If you have chronic kidney disease, you should read these books. They can change your view about living with chronic disease.

    What Can I Do To Help Control My High Blood Pressure

    A healthy lifestyle is key to helping control any type of hypertension. Making changes in daily habits can help, such as:

    • Eating a heart-healthy diet: Choose fruits, vegetables, grains and low-fat dairy foods.
    • Exercising regularly, at least 30 minutes a day of moderate activity, such as walking .
    • Keeping your weight under control: Check with your healthcare provider for a weight-loss program, if needed.
    • Quitting smoking, if you smoke.
    • Cutting back on alcoholic drinks.
    • Limiting caffeine intake.
    • Limiting sodium in your diet: Read nutrition labels on packaged foods to learn how much sodium is in one serving.
    • Reducing and avoiding stress when possible: Many people find that regular meditation or yoga helps.

    What Are The Signs And Symptoms Of Kidney Disease

    blood pressure causes

    Like high blood pressure, early or mild kidney disease often has no signs or symptoms, so you might not know you have it. It is often picked up by a blood test done by the GP or hospital . As kidney disease progresses it can have a number of signs and symptoms, including:

    • changes to your wee, including changes in colour and smell, how often you need to wee, and how much liquid you pass
    • swelling in your legs, hands or face
    • tiredness
    • muscle cramps and paleness due to anaemia

    See your GP if you have any of these symptoms, particularly if they are ongoing.

    Diagnosis Of Kidney Disease

    Early diagnosis and optimal management can often prevent kidney damage from becoming worse and reduce the risk of kidney failure.

    Chronic kidney disease often has very few symptoms, or only general symptoms, such as tiredness, headaches and feeling sick. The doctor may begin by reviewing your medical history and performing a physical examination.

    The diagnostic tests for kidney disease chosen by your doctor depend on factors including your symptoms, age, medical history, lifestyle and general health. Tests for kidney disease include:

    • urine tests
    • biopsy.
