56 Unnerving Kidney Disease Statistics, Facts & FAQs

Kidney Disease Statistics

The majority of the population is born with two functioning kidneys. These organs are vital, meaning we can’t survive without at least one. Their role is to filter excess fluid and waste from the body. As the following kidney disease statistics discuss, healthy kidneys filter about 30 gallons of blood daily to get rid of the excess liquid and waste it contains. 

Muscle use and food consumption help produce this waste, which is filtered into the urine by our kidneys. Another important kidney function is controlling the chemicals and liquids in our bodies. They also control our blood pressure, keep our bones healthy, and help us in the process of making red blood cells. But what if it ever comes to kidney failure?

Keep reading to find out everything about kidney stones, chronic kidney disease, organ donation, and more. We’ve collected the most important stats and facts about kidney disease, and answered some of the most frequently answered questions.

General Facts About the Kidney

1. Every day our kidneys remove one half of a gallon of waste and liquid from our blood.

(American Kidney Fund)

Each day our kidneys—which are located near the middle of the back, on each side—work hard to clean our blood system. When the kidneys don’t work properly, this waste remains in the body, returning to our blood system, which can cause problems with the lungs, bones, heart, blood, and so on.

2. Kidney disease statistics report that 37 million Americans suffer from this disease.

(American Kidney Fund)

Not everyone is aware they have it because they may not experience the first-stage signs of kidney failure. Some kidney problems are only temporary, some can be an early sign of chronic kidney disease (CKD), and some can lead to CKD if they aren’t treated properly.

3. 10% of the world’s population suffers from chronic kidney disease.

(National Kidney Foundation)

According to our chronic kidney disease statistics, millions of people die each year from this disease, often because they don’t have the means to afford treatment. In 1990, CKD was ranked 27th on the list of the leading causes of death worldwide. However, in 2010, it rose to 18th place. Only HIV and AIDs moved up the list more rapidly.

4. More than 2 million people across the world are receiving treatment for kidney disease right at this moment.

(National Kidney Foundation)

As claimed by our dialysis statistics, this is only 10% of all the people who need treatment to stay alive. The great majority of these people are treated in only 5 countries: the United States, Japan, Germany, Brazil, and Italy. These countries make up only 12% of the world’s population.

5. In 2005, there were 35 million deaths around the world caused by chronic diseases.

(National Kidney Foundation)

Diabetes and heart and kidney diseases have replaced influenza, malaria, and AIDs as the most common causes of premature death. As our chronic kidney disease statistics worldwide show, 80% of these deaths happen in low-income or middle-income countries, and 25% of those deaths occur in people who are under 60 years old.

6. The southern US states are among the top 10 hit hardest by kidney disease.

(National Kidney Foundation)

As the Centers for Disease Control (CDC) verify, more than 8% of people in these states also suffer from diabetes, which is the main cause of kidney failure. Physical inactivity and obesity have high rates in these regions, as well as other chronic diseases. The region is, unfortunately, also known as the “stroke belt,” according to many blood pressure and kidney disease facts.

7. Alabama, Mississippi, and Tennessee have 1,537 kidney disease patients per million people.

(National Kidney Foundation)

These states are at the top of the list. Right behind them is the region covering Georgia, North Carolina, and South Carolina, with 1,497 patients per million, and then there’s Southern California, with 1,408, and Texas, with 1,405. Arkansas, Louisiana, and Oklahoma are lumped into fifth place with 1,371 patients per million. And Maryland, Virginia, Washington DC, and West Virginia have 1,336 patients per million, according to the latest kidney disease statistics by state.

The US territories and regions with the highest numbers of patients also include American Samoa, Northern California, Guam, and Hawaii with 1,299 patients per million; New York with 1,267; and New Jersey, Puerto Rico, and the Virgin Islands with 1,258. Countries with the lowest number of kidney disease patients per million population are Alaska, Idaho, Montana, Oregon, and Washington, with 775 patients per million population.

Interesting Facts About Kidney Stones

8. About 11% of men and 6% of women in the United States will have kidney stones at least once in their lives.


Kidney stones are pieces of material that form in our kidneys when we have high levels of minerals in our urine. Their shapes and sizes are varied, and they can be smooth or jagged. They’re usually yellow or brown in color. Small kidney stones may pass through the urinary tract unnoticed, while the larger ones may cause some damage if they aren’t treated by a medical professional.

9. In the case of kidney stones, the facts state that if you’ve already had one, there’s a 30% to 50% chance that more will form in the next 5 years.

(Mental Floss)

Just having a kidney stone puts us at risk of having another. Reducing sodium—like that found in deli meats, packaged soups, and processed foods—may help us lower that risk. It’s also advised to avoid animal proteins, while drinking a lot of liquids and eating vegetables and fruits. Just be careful, because high levels of vitamin C may encourage the formation of calcium oxalate stones.

10. Kidney stones were mentioned for the first time around 5,000 years ago.

(Mental Floss)

The historical facts about kidney stones report that old Mesopotamian medical texts discuss this painful experience. They also mention interventions against kidney stones. They’re even mentioned in the Hippocratic Oath, urging physicians to “not use the knife, not even on sufferers from stone.” In ancient Greece and India, surgeons removed kidney stones, according to texts from the 7th century BCE.

11. The period from the 16th to 18th centuries was the prime time for self-taught surgeons.

(Mental Floss)

One of the most infamous of them was Frère Jacques Beaulieu. He was the pioneer in lateral perineal lithotomy. According to the kidney stone facts, he did more than 5,000 lithotomies, and most of them were deadly. The process consisted of making an incision in the perineum, inserting a cutting instrument into the bladder, cutting up the stone, and then extracting the pieces with the instrument or his fingers. He was finally banned from doing this monstrous procedure in 1698, after 25 of his 60 patients died.

12. In 2009, a 2.5 lb kidney stone was removed from a man in Hungary.

(Mental Floss)

According to additional kidney stone statistics, the world record for largest kidney stone was set in 2004, when a stone the size of a mouse was removed from a man—it was 5.11 inches wide. The most unusual and record-breaking kidney stones are located in the International Museum of Surgical Science.

13. Men over the age of 50 are more likely to have bladder stones.

(Mayo Clinic) (Healthline)

Bladder stones and kidney stones are often mistaken to be the same, but they are not. Facts about kidney disease state that bladder stones are minerals in the bladder that form when the bladder isn’t completely emptied. Bladder stones, even the larger ones, may not cause trouble. 

Just in case, it’s good to know the symptoms: lower abdominal pain, pain during urination, frequent urination, difficulty urinating or interrupted urine flow, blood in the urine, and cloudy or abnormally dark urine. On the other hand, symptoms of kidney stones include pain or burning during urination, an urgent need to urinate, blood in the urine, urine with a cloudy color and strange smell, the slow flow of urine, vomiting, nausea, fever and chills, and pain in the back, stomach, or side.

Chronic Kidney Disease Facts

14. 15% of US adults suffer from chronic kidney disease.

(National Kidney Foundation)

That’s more than 1 in 7 adults. In addition, 1 in 3 adults in the US is at risk of developing chronic kidney disease. Very often, kidney disease symptoms don’t show until the disease has progressed greatly. Hydronephrosis and chronic kidney disease, which develops over time—in many cases over a span of a few years—are just some of the consequences.

15. There are 5 stages of chronic kidney disease, according to the chronic kidney disease facts.

(American Kidney Fund)

The stages are based on the kidneys’ ability to do their job. The safest way to detect kidney disease is by an eGFR blood test, which measures kidney function. In stage 1 kidney disease, the damage to the kidneys is very mild, and there are almost no symptoms. The eGFR test shows values greater than 90. In stage 2, there are generally no symptoms, and the eGFR test shows values between 60 and 89. The kidney disease facts indicate that although there is kidney damage, at these stages they’re still considered healthy and can work well.

Stage 3 kidney disease indicates that the kidneys are moderately damaged, and can’t function very well. People are more likely to have health complications from the waste that has accumulated in their bodies. The eGFR test shows values between 30 and 59, and there may be some symptoms like back pain, swelling in the hands and feet, and problems with urination, as our kidney statistics show. Stage 4 kidney disease shows severe kidney damage, and eGFR values between 15 and 30. This stage includes health issues like high blood pressure, anemia, and bone disease.

16. Close to 2 million people across the world are affected by end-stage kidney disease.

(University of California) (American Kidney Fund)

Stage 5 kidney disease is end-stage kidney—or renal—disease (ESRD). The eGFR is less than 15, and the kidneys are dangerously close to failure. Symptoms in this stage include vomiting, nausea, itching, muscle cramps, not feeling hungry, back pain, swelling in the hands and feet, and problems urinating, breathing, and sleeping.

17. Every year, 750,000 people in the United States are affected by end-stage renal disease.

(University of California)

As stated in renal failure statistics, the number of people who suffer from ESRD is steadily increasing by 5% every year in the United States alone. On a global level, the number of people who suffer from ESRD increases by 5%–7% every year. Mortality rates depend on ESDR treatment, but they are 15% higher in the US than in Europe. At this moment, ESDR is most commonly found in Taiwan, Japan, Mexico, the United States, and Belgium.

18. Hispanics and Native Americans are 1.5 times more likely to suffer from ESRD.

(University of California) (Chronic Kidney Disease)

Kidney disease can affect individuals of all races and ages. However, among those who are African American, kidney disease statistics show them having a greater chance of suffering from ESDR. In fact, this demographic is 3.5 times more likely to suffer from end-stage renal disease, compared to whites. 

ESDR’s effects are disproportionate. It mostly affects the nation’s minority and low-income patients. This risk is partially due to the high rates of diabetes and high blood pressure in these communities. Also, chronic kidney disease can happen at any age, but it’s more common in older people. It’s also more common in women than in men.

Kidney Failure Statistics

19. Over 661,000 Americans suffer from kidney failure.


Kidney disease appears when a person’s kidneys are too damaged to process waste and excess liquids from the body. In this way, the waste accumulates in the body and causes other health issues. Kidney disease increases the chance of a heart attack or stroke. In addition, diabetes, high blood pressure, and a family history of kidney disease also increase a person’s chances of developing kidney disease.

20. In 2013, over 47,000 Americans died because of kidney disease.


The kidney disease death rate shows that each year kidney disease kills more people than prostate and breast cancer. Kidney disease is also known as the “silent disease” because symptoms of kidney disease seldom show in its first stages. Once the disease is discovered, it’s usually already very advanced.

21. Over 80% of those receiving kidney failure treatment have access to universal health care.

(National Kidney Foundation)

Most of them also come from affluent countries that have large populations of elderly people. Statistics on kidney disease predict that the number of cases of kidney failure will show a disproportionate increase in developing countries like India and China, where the number of elderly people is on a constant rise.

22. Every year, 1 million people die from untreated kidney failure.

(National Kidney Foundation)

Dialysis, a kidney transplant, and other kidney failure treatments are an enormous financial burden for everyone who needs this kind of treatment. People who don’t have access to universal health care often can’t afford any kind of treatment, which leads to an alarmingly high number of deaths every year.

23. In the case of kidney failure, the facts show that its treatment uses 6.7% of Medicare’s budget.

(National Kidney Foundation)

The treatment exceeds $48 billion each year. And this budget is spent on less than 1% of those covered by Medicare. Other countries have even greater expenses. For example, in the next 10 years, China will be hit with $558 billion in expenses for death and disabilities caused by kidney and heart diseases.

24. In 2015, 1.2 million people died from kidney failure, according to the more concerning facts about kidney failure.

(World Health Organization)

That is a staggering 32% increase from 2005. It’s also estimated that in 2010, 2.3 million to 7.1 million people died from kidney disease because they didn’t have access to treatment. Also, more than 1.7 million people die every year from acute kidney injuries. All in all, 5 to 10 million people die each year from kidney-related diseases.

25. Diabetes and high blood pressure are responsible for 75% of kidney failure cases.

(National Kidney Foundation)

Kidney disease stats also report that 45% of new kidney disease patients have a primary diagnosis of diabetes, and 29% of them have a primary diagnosis of high blood pressure, or hypertension. Other conditions that cause kidney failure include glomerulonephritis (diseases that cause damage to the filtering units of the kidneys), inherited diseases like polycystic kidney disease, immune diseases like lupus, deformities formed at birth that occur as the baby develops, a large prostate, kidney stones and other obstructions, and repeated urinary tract infections.

Facts About Kidney Cancer

26. Annually, there are 54,000 new cases of kidney cancer in the US alone.

(American Kidney Fund)

People over the age of 55 are more likely to suffer from renal cell carcinoma, but it can affect people of all ages and both genders. Some of the things that increase a person’s chances of having kidney cancer are smoking, obesity, high blood pressure, a family history of it, and other inherited diseases. Of course, these problems don’t guarantee that a person will get kidney cancer, just as not having them doesn’t mean a person won’t get kidney cancer.

27. As estimated in most kidney cancer statistics, this year there will be 73,820 people in the US diagnosed with kidney cancer.


44,120 men and 29,700 women will be diagnosed with this disease. This is the 6th most common cancer for males and the 8th most common one for females. The average age for kidney cancer diagnosis is 64. It’s rare for people younger than 45 to develop kidney cancer. Possible kidney cancer symptoms include blood in the urine, pressure or pain in the side or back, a lump or a mass in the side or back, swelling in the ankles and legs, high blood pressure, anemia, fatigue, loss of appetite, inexplicable weight loss, and fever.

28. Reliable kidney cancer facts predict that this year 14,770 people will die from kidney cancer.


This will total 9,820 men and 4,950 women, to be more accurate. The five-year survival rate shows that 75% of people with kidney cancer survive. Naturally, survival rates depend on the type and stage of the cancer. Around two-thirds of people are diagnosed when the cancer is only in the kidney, and their five-year survival rate is 93%. If the cancer spreads to nearby tissues, the rate decreases to 69%. In cases where the cancer has spread to distant parts of the body, the survival rate falls to 12%.

Polycystic Kidney Disease Statistics

29. About 600,000 people in the United States suffer from polycystic kidney disease.

(National Kidney Foundation)

Polycystic kidney disease occurs when there are numerous water-filled cysts in the kidneys. If the number of cysts is too great, the kidneys can suffer some damage. The growth of cysts can slowly replace the kidneys and cause kidney failure. This is the fourth main cause of kidney failure, and it can happen to both men and women of all ages and races.

30. About 25% of the people who suffer from polycystic kidneys have a floppy valve in the heart.

(National Kidney Foundation)

Some interesting facts about polycystic kidney disease show that this fluttering or pounding of the heart can be one of the first symptoms of polycystic kidney disease. Other symptoms include back or side pain, an increased abdomen size, blood in the urine, persistent bladder and kidney infections, and high blood pressure, which is the most common sign of polycystic kidney disease. Treating high blood pressure can lower or even prevent damage to the kidneys.

31. 90% of the people who suffer from polycystic kidney disease have autosomal dominant polycystic kidney disease.


As polycystic kidney disease statistics show, this is the most frequently inherited disease. It’s referred to as “dominant” because an individual has to inherit one copy of the gene from their parents. People who have inherited autosomal dominant polycystic kidney disease usually don’t experience any symptoms until they’re between 30 and 40 years old. The most common symptoms are high blood pressure, blood in the urine, and pain in the back, sides, and stomach.

Stats on Kidney Donation, Transplants, and Treatments

32. Around 90% of kidney disease patients on dialysis are treated with hemodialysis.

(University of California)

Hemodialysis is the most common kind of dialysis, as the dialysis statistics from 2018 report. It consists of pumping the patient’s blood through an external circuit to filter it and pump it back into the body. One session of hemodialysis usually lasts somewhere between 3 and 5 hours, and it’s recommended to have 3 weekly sessions.

33. About 35% of hemodialysis receivers remain alive after 5 years of treatment.

(University of California)

This type of kidney disease treatment has only short-term effects, not to mention a few drawbacks. According to most dialysis facts, even though hemodialysis’s effects are short-term, the treatment can help extend patients’ lives. Hemodialysis can also be inconvenient and a bit confining, since patients are literally tied to a machine that pumps their blood. It’s also exhausting, can cause obesity, and the mortality rates are high.

34. Every year, Medicare spends $90,000 per patient on hemodialysis.

(University of California)

Medicare coverage is available for everyone who needs dialysis or kidney transplantation to stay alive. As the kidney dialysis facts show, this cost accumulates to $28 billion every year in the United States alone. 

35. In 2015, over 120,000 adults in the US underwent hemodialysis.

(MedTech Dive)

Half of them were older than 65. Since the number of hemodialysis patients is so high, and growing fast, hemodialysis machine companies are working on improving the machines in order to enhance the treatment and reduce any complications that can impact mortality rates.

36. Approximately 2.65 million patients around the world are on hemodialysis.


The dialysis stats also report that 40% of dialysis patients live in the United States, Europe, and Japan. 341,000 patients undergo peritoneal dialysis, which represents nearly 11% of dialysis patients. Most often, dialysis patients undergo treatments in centers, and there are approximately 40,000 dialysis centers in the world.

37. Every day 13 people die waiting for a kidney transplant.

(National Kidney Foundation) (Mayo Clinic)

Kidney transplants are a necessary surgical intervention in which a diseased kidney is replaced with a new, healthy one from a living or deceased organ donor. A kidney transplant can help treat chronic kidney disease and end-stage renal disease. Compared to a lifetime of dialysis, a kidney transplant is a much better choice for patients.

38. For those on the kidney transplant waiting list, statistics show that the average waiting time for a new kidney is 3 to 5 years.

(National Kidney Foundation)

Some patients may receive a new kidney quickly, and some may have to wait for more than 5 years. Some of the factors that influence the waiting list include how well the patient matches with the available kidney, the blood group, and whether the patient has been sensitized with high antibody levels from previous transplants, blood transfusions, and pregnancies. It also depends on how many donors are available in certain areas.

39. Kidney donation statistics show that in 2014, there were 5,538 living donors in the United States.

(National Kidney Foundation)

All living donors must be at least 18 years old to consent to organ donation. The total number of deceased donors was 7,761 in the same year. However, this number doesn’t add up to the total number of deceased donor transplants, since some deceased donors are able to donate both kidneys.

40. In 2014, there were 17,107 kidney transplants in the United States.

(National Kidney Foundation)

As indicated by the kidney transplant statistics, 11,570 of donated kidneys came from deceased donors, and 5,537 kidney donations came from living donors. Acceptable organ donors can range from newborn babies to 65-year-olds. Donor organs are matched to the patients on the waiting list by the National Organ Procurement and Transplantation Network (OPTN). The OPTN is operated by the United Network for Organ Sharing (UNOS).

41. Dialysis patients have an average life expectancy of 5 years.


On the other hand, kidney transplant life expectancy statistics show that people who receive a kidney donation live longer. The average life expectancy for people with a living donor kidney donation is 12 to 20 years, and for people with a deceased donor kidney donation, it’s 8 to 12 years.

42. People who receive a new kidney before dialysis live 10 to 15 years longer than those undergoing dialysis for treatment.


The younger the patient, the more they will benefit from a kidney transplant, but kidney transplant facts show that even the elderly can gain approximately four years more than if they underwent dialysis. Some patients may have to undergo dialysis before getting a new kidney, but that doesn’t ruin their chances of getting a donation.

43. Patients waiting for a new kidney who are on dialysis for 2 years have 3 times greater chances of losing the transplanted kidney.


Research shows that undergoing dialysis for a long time before a kidney transplant influences the life of the new kidney. Kidney donation facts also state that even the benefits of a living organ donation may decrease if the patient has been on dialysis for more than 2 years. The collected data shows that donated kidneys work much better and for a longer time if patients get a transplant before they undergo dialysis. In general, getting a transplant is much better for the overall health of the patients, since dialysis can cause health issues over a period of time.

The Bottom Line

As we have seen throughout this article, the kidneys are a vital part of our body. From making hormones and processing waste to even more serious functions, they’re among several key organs that keep us alive. These kidney disease statistics sound startling and unnerving, but it’s important to remember them in order to make kidney health a main priority. So take care of your vital organs, maintain a healthy lifestyle, and be sure to contact your doctor if you suspect you may be suffering from kidney disease.


What is kidney disease?


Kidney disease is the inability of the kidneys to process excess liquids and waste from our bodies. When one or both kidneys are damaged, the excess liquids and waste build up and go back into our bodies, instead of being eliminated through urination, as in the case of healthy kidneys.

What causes kidney disease?

(National Kidney Foundation)

The two main causes of kidney disease in the US are type 2 diabetes and high blood pressure. If these conditions are discovered in time and treated properly, kidney disease can be slowed down, or even prevented. The third main cause of kidney disease is glomerulonephritis, which is a disease that damages the filtering units of the kidneys. Other causes of kidney disease may include frequent urinary infections, kidney stones, various inherited diseases like polycystic kidney disease, overuse of painkillers and other over the counter medications, and the abuse of certain substances.

What is chronic kidney disease?

(Mayo Clinic)

Chronic kidney disease (CKD), also known as chronic kidney failure, represents the gradual loss of the function in the kidneys. In the early stages of chronic kidney disease, patients may not experience symptoms. Therefore, when CKD is discovered, the disease is usually in the more advanced stages. The progress of kidney disease can be slowed down with treatment, which usually includes controlling the underlying cause of kidney disease.

How fast does chronic kidney disease progress?


In most cases, chronic kidney disease progresses slowly. Sometimes years can pass before the disease reaches another stage. It’s of great importance to take blood and urine tests regularly to monitor the progress of the disease. The tests can determine the stage of the disease and how quickly it’s developing.

What are the stages of kidney disease?


Chronic kidney disease has 5 stages. In stage 1, urine tests show signs of kidney damage, but the organ can still work well. In stage 2, the test shows kidney damage, and the kidney is not working at full capacity. However, kidney function decreases only slightly, and there still may be no symptoms of kidney disease. In stage 3, the kidney’s function is fairly reduced. In stage 4, the test shows severe kidney damage, and there’s an abundance of symptoms like itching, anemia, and pain in the bones. Stage 5 represents end-stage kidney (or renal) disease. The kidney is so damaged it can barely function, and dialysis or a kidney transplant is needed to treat the disease.

How long can you stay in stage 3 kidney disease?


Chronic kidney disease can take years to progress from one stage to another. It greatly depends on the individual. A person with stage 3 CKD should see their doctor regularly and watch their diet, blood pressure, and glucose levels. It is possible to slow down the progress of CKD by maintaining a healthy lifestyle.

What are the symptoms of kidney disease?

(Life Options)

The symptoms can be subtle, and some of these symptoms may indicate other problems. The only way to be sure that you have kidney disease is to visit a doctor. Nevertheless, some of the most common kidney disease symptoms include fatigue, being cold when other people aren’t, shortness of breath after little effort, feeling dizzy and weak, not being able to think clearly, itching, metal-tasting food, ammonia breath, nausea and vomiting, changes in the urine, and swelling in the hands, feet, and face.

What are the best ways to prevent kidney disease?

(American Kidney Fund)

When it comes to how to prevent kidney disease, a healthy lifestyle is the key. If you suffer from diabetes or high blood pressure, you should work with your doctor to keep these conditions under control. If you want to lower your chances of developing the disease, you should maintain a healthy, low-salt and low-fat diet, visit your doctor for regular check-ups, exercise at least 30 minutes a day for most days of the week, stop smoking if you do, and avoid drinking alcohol.

9. What should you avoid eating if you have kidney disease?


The diet you follow greatly depends on the stage of the disease. As for what not to eat when you have kidney disease, the so-called “renal diet” usually limits sodium and potassium daily intake to 2,000 mg. Damaged kidneys have trouble processing waste from our bodies. Because of this, it’s best to avoid consuming dark-colored colas, avocados, canned food, whole wheat bread, brown rice, bananas, dairy, processed meat, oranges and orange juice, relish, pickles and olives, apricots, potatoes, tomatoes, pre-made and instant meals, swiss chard, spinach, beet greens, dates, raisins, prunes, pretzels, chips, and crackers.

How does diabetes cause kidney disease?

(American Diabetes Association)

As mentioned, kidneys filter the waste from our bodies, so the influence of diabetes on our kidneys is massive. High blood sugar levels cause the kidneys to pump more blood. This extra filtering puts the kidneys under pressure, which can lead to protein loss through the urine. Overworking the kidneys can lower their filtering abilities over time, which can further lead to kidney failure.

How many people are diagnosed with kidney disease?

(National Kidney Foundation)

Approximately 1 in 7 adults in the United States suffers from kidney disease. That’s almost 30 million people in the US alone. Moreover, 96% of those who have stage 1 or 2 kidney disease aren’t aware of it. Furthermore, 48% of those who have stage 4 kidney disease but aren’t on dialysis are also unaware of their condition.

What percentage of kidney function is considered kidney failure?

(Cleveland Clinic)

If an individual has two healthy kidneys, then they have 100% kidney function. If the kidneys lose 30% to 40% of their function, a person may not even notice a change. It’s also possible to live even with just one healthy kidney. But if kidney function falls to 25%, some serious health issues arise. Kidney failure usually happens when kidney function drops to 10%–15%. At this point, dialysis or a kidney transplant are the only options left for a person to survive.

What country has the highest kidney disease rate?


Research shows that 1 in 10 people worldwide suffers from kidney disease. The highest prevalence rates among high-income countries include Saudi Arabia and Belgium, both with 24%. Poland and Germany follow, with 18% and 17% respectively, and the United Kingdom and Singapore are behind them with 16% both. On the other hand, Norway and the Netherlands have only a 5% prevalence of kidney disease. We are yet to see what will the kidney disease statistics from 2020 show.
