Keep Blood Pressure in a Healthy Range: Hypertension is both a cause and a consequence of chronic kidney disease, and blood pressure is among the best-established influences on how fast kidney function declines. Reducing dietary sodium, staying physically active, keeping weight in a healthy range and moderating alcohol all contribute. KDIGO (PubMed)
Manage Blood Sugar If Diabetic: Diabetic kidney disease is the leading cause of kidney failure. Keeping glucose near individualized targets helps limit kidney damage, and SGLT2 inhibitors have been shown to slow CKD progression in people with and without diabetes (DAPA-CKD trial). Early screening with the urinary albumin-to-creatinine ratio can detect kidney damage before eGFR declines. New England Journal of Medicine (PubMed)
Know That Kidney Disease Is Usually Silent: CKD is often symptomless until it is advanced, and many people who have it are unaware. Simple blood and urine tests detect it, and they are routine parts of general health checks. If you have diabetes, high blood pressure, or a family history of kidney disease, it is worth knowing that those tests exist and asking whether they apply to you. KDIGO (PubMed)
Go Easy on Painkillers and Stay Hydrated: Regular heavy use of over-the-counter anti-inflammatory painkillers such as ibuprofen and naproxen reduces blood flow to the kidneys, particularly alongside dehydration or reduced kidney function. Some herbal remedies stress the kidneys too. Staying well hydrated helps, and any ongoing need for daily pain relief is worth raising with a clinician. NIDDK (NIH)
Maintain Cardiovascular Health: Cardiovascular disease, rather than progression to dialysis, is the leading cause of death in people with CKD. Managing blood pressure, lipids, blood sugar, and body weight supports both kidneys and heart. The relationship is bidirectional, so steps that protect one organ system tend to benefit the other.

Background and further reading
Chronic kidney disease (CKD) is defined as abnormalities of kidney structure or function - most often an estimated glomerular filtration rate (eGFR) below 60 mL/min/1.73 m² and/or albuminuria - that persist for more than 3 months [2]. It affects roughly 10% of adults worldwide, on the order of 800 million people [4]. CKD is staged by eGFR and albuminuria, and it is often silent until advanced stages, when it can cause fatigue, swelling, nausea, and cognitive difficulty; surveys find that most adults with CKD are unaware they have it [4]. Stage 5 (kidney failure) typically requires dialysis or transplantation. CKD also substantially raises cardiovascular risk, and many people with CKD experience a cardiovascular event before ever reaching dialysis [2].
Genetic Basis: Kidney function is moderately heritable: twin and family studies put the heritability of eGFR broadly in the 30-50% range, though estimates vary widely by study and age. The trait is highly polygenic - a trans-ancestry meta-analysis of more than a million individuals cataloged 264 loci associated with eGFR (166 of them new), with one of the strongest and most replicated signals at UMOD, which encodes uromodulin, the most abundant protein in normal urine [1]. Other well-established kidney-function loci include SHROOM3 and GATM. The APOL1 G1 and G2 variants, common in people of recent African ancestry, are associated with elevated kidney-disease risk; for CKD overall the effect of carrying two risk alleles is modest (roughly 1.5-fold), but it is far larger for specific kidney conditions such as focal segmental glomerulosclerosis and hypertension-attributed kidney failure [3]. Rare monogenic disorders, including polycystic kidney disease and Alport syndrome, account for a smaller share of cases.
Modifiable Risk Factors: Diabetes and high blood pressure are the two leading causes of CKD and together account for roughly two-thirds of new cases of kidney failure [4]. Other contributing factors include obesity, smoking, and the regular use of NSAIDs such as ibuprofen and naproxen, which reduce blood flow to the kidneys [4]. Early detection and treatment of these factors can meaningfully slow progression. Blood-pressure control is one of the best-established interventions: the KDIGO 2021 guideline recommends a target systolic pressure below 120 mmHg using standardized office measurement for most adults with CKD, where tolerated [5], while other guidelines favor a <130/80 mmHg target - the appropriate goal is individualized.
