That is more than 1 in 10 adults on Earth โ a global age-standardised prevalence of 14.2%, up from 378 million in 1990. CKD is now the 9th leading cause of death worldwide, killing 1.48 million people per year. It is silent, often asymptomatic until advanced stages, and disproportionately deadly in low-income countries where dialysis and transplant are largely unavailable.

788 million people aged 20 and older worldwide have chronic kidney disease (CKD) as of 2023 โ equivalent to a global age-standardised adult prevalence of 14.2%, up from 378 million in 1990, according to the GBD 2023 Chronic Kidney Disease Collaborators (The Lancet, November 2025). This represents more than 1 in 10 adults globally. CKD is the 9th leading cause of death worldwide, killing 1.48 million people per year. Most people with CKD have Stage 1โ3 disease, but progression to end-stage kidney disease (ESKD) without dialysis or transplant is fatal โ and in low- and middle-income countries, most patients with ESKD have no access to life-saving renal replacement therapy.
Chronic kidney disease (CKD) is defined by KDIGO (Kidney Disease: Improving Global Outcomes) as the presence of kidney damage or a glomerular filtration rate (eGFR) below 60 mL/min/1.73mยฒ for three months or more, regardless of cause. It is classified into five stages (G1โG5) based on eGFR and albuminuria. Most people with CKD do not know they have it โ it is almost always asymptomatic until advanced stages โ making systematic screening and awareness critical.
The GBD 2023 data โ the most comprehensive and most recent available โ reveals that CKD's global prevalence more than doubled between 1990 and 2023, from 378 million to 788 million. This rise is primarily driven by the parallel epidemics of diabetes and hypertension, the ageing of the global population, and the increasing prevalence of obesity. While the age-standardised rate has risen only modestly (+3.5% relative increase since 1990), the absolute number of affected individuals has grown dramatically as world population expanded and aged.

CKD is not merely a kidney disease โ it is a cardiovascular amplifier and systemic burden. According to GBD 2023, impaired kidney function as a risk factor accounts for 11.5% of all cardiovascular deaths globally. Every stage of CKD increases the risk of heart attack, stroke, and sudden cardiac death. In many patients, cardiovascular complications kill before kidney failure itself progresses to ESKD requiring dialysis.
๐ Key TakeawayCKD's most devastating feature is not how many people have it, but how invisible it is. Because CKD has no symptoms until Stage 4 or 5, the vast majority of the 788 million people affected globally do not know their kidneys are failing. Awareness, detection, and early treatment โ with ACE inhibitors, SGLT2 inhibitors, blood pressure control, and diabetic management โ can halt progression for years or decades. The tragedy is that in low-income countries like many in sub-Saharan Africa, even these inexpensive interventions are often unavailable or unaffordable, while dialysis โ the lifeline when kidneys fail โ is accessible to only a fraction of those who need it.

๐ Key Takeaway โ Data BreakdownDiabetes and hypertension together drive the majority of global CKD โ meaning most CKD is theoretically preventable through better metabolic control, blood pressure management, and lifestyle modification. In sub-Saharan Africa, however, CKD has a unique profile: hypertension-driven disease dominates, but so does CKD of unknown aetiology (CKDu), HIV-associated nephropathy, and infection-driven glomerulonephritis โ a "double burden" of communicable and non-communicable drivers that no single intervention addresses. APOL1 gene variants (G1 and G2) common in West African populations confer up to 50% lifetime risk of HIVAN and dramatically elevated risk of focal segmental glomerulosclerosis โ a genetic vulnerability that further amplifies the CKD burden in Africa.

Section 3
Trend Over Time โ Three Decades of Rising Burden
The GBD 2023 data documents one of global health's most consistent trends: a relentless absolute rise in the number of people living with CKD since 1990, driven by population growth, ageing, and the parallel diabetes and hypertension epidemics. The age-standardised rate โ which controls for these demographic shifts โ has risen more modestly, but the absolute human toll is staggering.

๐ Key Takeaway โ TrendCKD is one of the fastest-rising causes of death and disability globally. While most leading diseases (heart disease, stroke, many cancers) have seen declining age-standardised mortality rates since 1990 in high-income countries, CKD mortality has increased in almost every region. It moved from the 27th cause of death in 1990 to the 9th in 2023 โ driven not by better detection alone, but by genuine increases in underlying risk factors (diabetes, hypertension, obesity) and, in sub-Saharan Africa, by CKDu, HIV, and infections. GBD projections suggest CKD could become the 5th highest cause of years of life lost by 2040 if current trajectories continue.

Country & Regional Comparison โ Access Inequality
CKD's burden is global, but what separates life from death for ESKD patients is access to renal replacement therapy (RRT) โ dialysis or kidney transplant. This is where the world's most extreme healthcare inequality exists: in high-income countries, essentially all patients who need dialysis receive it. In low-income countries, the overwhelming majority die without it.

๐ Key Takeaway โ Country ComparisonThe global KRT access gap โ a factor of 200 between rich and poor regions โ is the single most visible expression of healthcare inequality in CKD. In Nigeria, CKD patients reaching ESKD have essentially no access to chronic haemodialysis through public funds; they rely entirely on private payment that most cannot afford. The Lancet Global Health 2024 found that seven countries โ including Nigeria, Ghana, and DRC โ rely solely on private and out-of-pocket payments for haemodialysis. There are fewer nephrologists in the entire sub-Saharan African region than in some individual US teaching hospitals. New treatments โ particularly SGLT2 inhibitors (dapagliflozin, empagliflozin) โ can slow CKD progression by ~40% and are increasingly recommended by KDIGO, but affordability and availability in LMICs remain major barriers.

Why This Matters โ Patient Impact, Policy & SDGs
The Silent Killer โ Living With CKD
CKD profoundly diminishes quality of life long before kidney failure. Fatigue, anaemia, fluid retention, bone disease, cognitive impairment, and cardiovascular risk shadow patients through stages 3 and 4. The 12th leading cause of DALYs globally, CKD's disability burden extends far beyond mortality statistics. For patients in Nigeria and sub-Saharan Africa reaching ESKD, the choices are stark: unaffordable private dialysis (typically โฆ150,000โโฆ400,000 per month in Nigeria, far exceeding minimum wage), medical tourism abroad, or death. The International Society of Nephrology estimates that over 2 million people die each year from lack of access to kidney replacement therapy globally โ the vast majority in sub-Saharan Africa and South Asia.
The economic cost of CKD is enormous. In the USA alone, Medicare spending on ESKD was over US$51 billion in 2021 (USRDS). Globally, the cost of dialysis for all who need it has been estimated at over US$1 trillion annually if treatment were universalised โ a figure that underscores why global equity remains elusive.
"Globally, in 2023, 788 million people aged 20 years and older were estimated to have chronic kidney disease, up from 378 million in 1990. CKD is a major global health issue, with rising prevalence and increasing importance as a cause of death and as a risk factor for cardiovascular death."

SDG 3 & the 2040 Projection
CKD sits at the intersection of SDG 3 (Good Health and Well-Being) and SDG 10 (Reduced Inequalities). WHO's Global Action Plan for NCDs targets a one-third reduction in premature NCD mortality by 2030 โ CKD's trajectory is moving in the opposite direction in most LMICs. The GBD 2017 report projected that CKD will become the 5th highest cause of years of life lost globally by 2040. New treatments โ SGLT2 inhibitors (dapagliflozin in DAPA-CKD: 39% risk reduction in ESKD/death; HR 0.61) and finerenone โ offer genuine hope for slowing progression but remain unaffordable in most of Africa and South Asia.

Methodology & Data Notes
๐ฌ How the Primary Statistic (788 million) Was Derived
Primary Source
GBD 2023 Chronic Kidney Disease Collaborators. "Global, regional, and national burden of chronic kidney disease in adults, 1990โ2023, and its attributable risk factors: a systematic analysis for the Global Burden of Disease Study 2023." The Lancet. Published 07 November 2025. doi:10.1016/S0140-6736(25)01853-7. Funded by Gates Foundation, Wellcome, US National Kidney Foundation, and NIDDK.
Population Scope
Adults aged 20 years and older. 204 countries and territories. GBD 2023 explicitly covers age 20+ for CKD; some earlier studies (GBD 2017/2021) reported all-age figures. This accounts for apparent differences between GBD cycles: the 843.6M figure from 2017 was all-age and used different methodology.
Data Sources Used
Published literature, vital registration systems (where available), kidney failure treatment registries, and household surveys. The Cause of Death Ensemble model and Bayesian meta-regression tool (DisMod-MR) produced the estimates. 100,983+ data sources were reviewed for GBD 2023.
CKD Definition
KDIGO 2012 criteria: eGFR <60 mL/min/1.73mยฒ and/or albumin-to-creatinine ratio (ACR) โฅ30 mg/g for โฅ3 months, regardless of cause. This is the internationally accepted diagnostic standard. Variation in which GFR equation is used (CKD-EPI, MDRD, CG) affects country-level estimates โ especially in Africa.
Uncertainty Range
788 million (95% UI: 743โ843 million). The uncertainty interval reflects data availability, modelling assumptions, and variation in underlying registries. Countries with complete vital registration have tighter intervals; African countries (with limited data) have wider intervals.
Why GBD Estimates Differ by Year
GBD 2017: 843.6M (all ages, older methodology) ยท GBD 2021: 673โ674M (revised methodology, now age 20+, different albuminuria inclusion) ยท GBD 2023: 788M (most comprehensive; 1990โ2023 range; adults 20+). These differences are methodological, not contradictory. GBD 2023 is the most current and authoritative.

Frequently Asked Questions
788 million people aged 20 and older worldwide have chronic kidney disease (CKD) as of 2023 โ representing a global age-standardised adult prevalence of 14.2% (95% uncertainty interval: 743โ843 million; 13.4โ15.2%). This figure comes from the GBD 2023 Chronic Kidney Disease Collaborators, published in The Lancet on 07 November 2025 (doi:10.1016/S0140-6736(25)01853-7), funded by the Gates Foundation, Wellcome Trust, US National Kidney Foundation, and NIDDK. It covers 204 countries and territories from 1990 to 2023, using data from published literature, vital registration, kidney failure registries, and household surveys. For comparison, in 1990 there were 378 million people with CKD โ meaning the global burden has more than doubled in 33 years. The global median CKD prevalence is also reported as 9.5% (IQR 5.9โ11.7%) by the ISN Global Kidney Health Atlas 2024 (Lancet Global Health, 2024) โ a slightly lower figure reflecting median across all countries rather than population-weighted global prevalence. Both figures are valid; the 14.2% global age-standardised estimate from GBD 2023 is the most comprehensive and methodologically rigorous. (Sources: GBD 2023 ยท The Lancet Nov 2025 ยท ISN GKHA ยท Lancet Global Health 2024)
CKD caused 1.48 million deaths globally in 2023 (95% UI: 1.30โ1.65 million), making it the 9th leading cause of death worldwide according to GBD 2023 (The Lancet, November 2025). In addition, CKD is the 12th leading cause of disability-adjusted life years (DALYs), with an age-standardised DALY rate of 769.2 per 100,000. Beyond its direct mortality, impaired kidney function as a risk factor accounts for 11.5% of all cardiovascular deaths globally โ meaning CKD's contribution to the global death toll is far larger than its direct death count suggests. Separately, the International Society of Nephrology (ISN) estimates that over 2 million people die annually from lack of access to kidney replacement therapy โ these patients reach end-stage kidney disease but cannot access dialysis or transplant, primarily in sub-Saharan Africa and South Asia. GBD 2021 reported 1.5 million direct CKD deaths. The trajectory from 1990 to 2023 shows consistent increase: CKD moved from the 27th cause of death in 1990 to the 12th in 2017 to the 9th in 2023. (Sources: GBD 2023 ยท The Lancet Nov 2025 ยท ISN GKHA 2024)
The leading causes of CKD globally are: (1) Diabetes mellitus (diabetic kidney disease / DKD): The single largest contributor โ diabetic nephropathy accounts for approximately 32% of all CKD DALYs globally (GBD 2017). In people with diabetes, 11โ83.7% develop CKD in Africa (PMC systematic review). (2) Hypertension (high blood pressure): The second major cause; hypertensive nephrosclerosis progressively damages glomeruli. CKD prevalence among hypertensive US adults was 35.8% vs 10.2% in normotensives. (3) Glomerulonephritis: Immune-mediated kidney inflammation โ particularly IgA nephropathy in East Asia; post-infectious glomerulonephritis in sub-Saharan Africa. (4) CKD of Unknown Aetiology (CKDu): Particularly prominent in sub-Saharan Africa, Sri Lanka, and Central America โ linked to environmental toxins, heat stress, and pesticide exposure; accounts for up to 65.8% of CKD in some East African populations. (5) APOL1 gene variants: G1 and G2 variants common in West African populations confer dramatically elevated CKD risk โ up to 50% lifetime risk for HIV-associated nephropathy (HIVAN), OR 10.5โ16.9 for focal segmental glomerulosclerosis. (6) Polycystic Kidney Disease (PKD): Genetic; ~1 in 1,000 globally. (7) AKI progression: Non-recovery from acute kidney injury progresses to CKD โ especially from malaria, sepsis, obstetric complications in sub-Saharan Africa. (Sources: GBD 2023 ยท PMC9073222 ยท MDPI Applied Sci 2023 ยท Wiley Nephrology 2024)
Nigeria's CKD prevalence varies significantly depending on the diagnostic equation used and the population studied. A systematic review (PMC5968792, 2018) of 7 population-based Nigerian studies found: Using Cockcroft-Gault equation: 24.4โ26% prevalence. Using MDRD equation: 2.5โ14.2% (most studies: 12.3โ14.2%). Using CKD-EPI equation: 11.4% (one study). The review concluded that CKD prevalence in Nigeria is high but variable, influenced by equation choice. Nigerian population studies have identified these key risk factors: hypertension (most common), diabetes mellitus, obesity, family history of kidney or hypertensive disease, use of traditional herbal medications (a major, underappreciated nephrotoxic risk in Nigeria), and HIV. In Nigeria, unlike high-income countries, chronic glomerulonephritis and interstitial nephritis from infections (malaria, schistosomiasis, HIV, HBV) remain important causes alongside NCDs โ the "double burden." CKD of unknown aetiology (CKDu) accounts for up to 21.5% of all renal admissions in Nigeria. The treatment gap in Nigeria is severe: chronic dialysis is not publicly funded, relies entirely on private payment, and costs โฆ150,000โโฆ400,000+ per month โ unaffordable for most Nigerians. Fewer than 5 nephrologists per million people serve the country. (Sources: PMC5968792 ยท Lancet GH 2024 ยท Wiley Nephrology 2024 ยท MDPI 2023)
CKD stages 1โ3 can often be significantly slowed or stabilised with proper treatment, and in some early cases (where the underlying cause is corrected), kidney function can partially recover. However, CKD is generally progressive and cannot be reversed once significant nephron loss occurs. Key evidence-based treatments include: (1) SGLT2 inhibitors (dapagliflozin, empagliflozin): The landmark DAPA-CKD trial showed a 39% risk reduction in ESKD, โฅ50% eGFR decline, or death (HR 0.61; 95% CI 0.51โ0.72; p<0.001), regardless of diabetes status. Now the standard of care in KDIGO 2024 guidelines for CKD with proteinuria. (2) ACE inhibitors / ARBs (e.g. lisinopril, losartan): Reduce proteinuria and slow progression โ essential for diabetic and hypertensive nephropathy; inexpensive and widely available. (3) Blood pressure control: Target <130/80 mmHg in CKD โ reducing BP dramatically slows progression. (4) Finerenone: Non-steroidal mineralocorticoid receptor antagonist โ reduces ESKD and CV outcomes in CKD with type 2 diabetes. (5) Blood sugar control in diabetes: HbA1c <7% target prevents DKD onset and slows progression. (6) Renal replacement therapy (dialysis/transplant): For Stage 5 ESKD โ kidney transplant is far superior to dialysis in outcomes. For Nigeria: ACE inhibitors are available and affordable through NHIA. SGLT2 inhibitors are increasingly available in private pharmacies but expensive. Finerenone is not yet widely available. Early detection and BP/sugar control at primary care level are the most actionable interventions. (Sources: DAPA-CKD trial ยท KDIGO 2024 ยท KDIGO guidelines ยท PMC)
CKD is called the "silent disease" because it has essentially no symptoms until Stage 4 or 5 โ by which time significant, often irreversible, kidney damage has already occurred. This is why screening is critical for people with diabetes or hypertension. When symptoms do appear, they include: (1) Swelling (oedema): Puffy feet, ankles, and legs from fluid retention โ a sign of advanced CKD. (2) Persistent fatigue and weakness: Caused by anaemia (CKD impairs erythropoietin production) and uraemia (toxin build-up). (3) Changes in urination: Foamy urine (protein leaking into urine โ proteinuria), increased frequency at night (nocturia), decreased urine output in ESKD, or blood in urine. (4) Loss of appetite, nausea, and vomiting: From uraemic toxin accumulation in Stages 4โ5. (5) High blood pressure that is difficult to control: CKD both causes and is worsened by hypertension. (6) Itchy skin: Phosphate and other waste build-up in Stages 4โ5. (7) Muscle cramps and bone pain: Mineral bone disorder from CKD. Screening approach: Any person with diabetes, hypertension, or family history of kidney disease should have annual screening โ a blood test (eGFR via serum creatinine) and urine test (albumin-to-creatinine ratio) performed at any hospital or laboratory. These are inexpensive, widely available in Nigeria, and can detect CKD years before symptoms appear. (Sources: KDIGO 2024 ยท WHO ยท PMC9073222 ยท ISN GKHA 2024)
The global CKD burden is projected to continue rising for three interconnected reasons: (1) Population ageing: Kidney function naturally declines with age; as populations in every world region age, a higher proportion of people will develop CKD even without any change in underlying risk factors. (2) The diabetes pandemic: Globally, over 537 million adults have diabetes (IDF 2021) and this is projected to reach 783 million by 2045. Diabetic kidney disease is the single largest cause of CKD โ every new diabetic patient is a future CKD risk. (3) The hypertension epidemic: Hypertension affects approximately 1.28 billion adults globally (WHO 2023) โ particularly in sub-Saharan Africa where urbanisation, salt-heavy diets, obesity, and lack of screening drive uncontrolled hypertension rates above 50% of all adults in some countries. (4) Rising obesity: Obesity directly damages kidneys through hyperfiltration, oxidative stress, and insulin resistance โ and accelerates both diabetes and hypertension. (5) Limited prevention in LMICs: Most CKD is preventable through diabetes and hypertension control โ but in LMICs, these conditions are often diagnosed late and poorly managed. GBD projections: CKD is expected to become the 5th leading cause of years of life lost globally by 2040 (PMC9073222 citing GBD projections). The burden in sub-Saharan Africa will grow disproportionately as the continent urbanises and adopts risk-increasing lifestyle patterns.
