Chronic kidney disease is a long term, progressive loss of kidney function that often develops silently over many years. It is usually staged using estimated glomerular filtration rate and markers of kidney damage such as albumin in the urine. Diabetes and high blood pressure are the main causes worldwide, with obesity, smoking, cardiovascular disease, and aging further increasing risk.

Research shows that early stages are frequently asymptomatic, which leads to underdiagnosis and late presentation. Screening of high risk groups using simple blood and urine tests is strongly supported, since early detection allows measures that can slow progression. These include strict blood pressure control, optimal blood sugar management in diabetes, reduction of dietary sodium, and the use of medications that block the renin angiotensin aldosterone system.

Recent studies highlight that chronic kidney disease is closely linked to cardiovascular disease, and that even mild impairment greatly increases heart attack, stroke, and mortality risk. Novel drugs such as sodium glucose cotransporter 2 inhibitors and nonsteroidal mineralocorticoid receptor antagonists have been shown to slow kidney function decline and reduce cardiovascular events in people with and without diabetes.

Research also points to large global inequalities. Low and middle income countries face rising burdens due to increasing diabetes and hypertension, limited access to screening, and late referral for specialist care. Environmental and social factors, including exposure to toxins, heat stress, and limited healthcare access, contribute to geographic and occupational clusters of disease.

Overall, the evidence emphasizes prevention, early detection, aggressive risk factor control, and broader public health strategies to curb the growing impact of chronic kidney disease.
