Chronic Kidney Disease

Overview

Chronic kidney disease (CKD) means the kidneys have been functioning below their normal capacity for at least three months, and the change is long-standing rather than temporary. It is usually silent in its early stages and is most often discovered on a routine blood or urine test. CKD is staged by the level of eGFR and the amount of albumin in the urine, and the stage guides how closely it is watched and what treatment is needed. Importantly, early CKD is not the same as kidney failure — most people with early CKD never reach kidney failure, and the right treatment can keep it that way. This is the main disease-focused page; Reduced Kidney Function, Low eGFR and Kidney Health Monitoring link here for the more specific angles.

How CKD is staged

CKD is described by the eGFR (from G1, normal or high, down to G5, kidney failure) together with the level of albumin in the urine (A1 to A3). The combination gives a clearer picture than either alone, because kidney function and albumin leak each predict risk independently. A person with a good eGFR but heavy albumin leak may still be at meaningful risk, while a small drop in eGFR with no albumin leak may be less concerning. Staging is therefore about risk and monitoring intensity, not alarm.

Common causes and associated conditions

• Diabetes — the commonest cause (see Diabetic Kidney Disease).
• High blood pressure — the second commonest cause (see Hypertensive Kidney Disease).
• Long-standing blockage or recurrent urinary problems (see Urinary Problems).
• Kidney stones or recurrent infections.
• Certain medicines taken long-term, especially some painkillers.
• Inherited conditions such as polycystic kidney disease.
• Glomerular (filter) inflammation and autoimmune disease.

Symptoms

Early CKD usually causes no symptoms. As function falls, possible features include tiredness, weakness, swelling of the legs or face, foamy urine, changes in urination, poor appetite, nausea, itching, and raised blood pressure. Many of these are not specific to the kidneys, which is why testing matters. Anaemia and bone-mineral changes can also develop in later stages.

Evaluation and investigations

Evaluation confirms reduced function over at least three months, identifies the cause, and assesses the stage and risk. Tests include repeat kidney function tests (creatinine and eGFR), urine ACR and routine microscopy, blood sugar or HbA1c and a lipid profile, a complete blood count, serum albumin and electrolytes, and an ultrasound of the kidneys. Further tests are selected when the pattern suggests a specific cause.

Management overview

Management aims to protect remaining function and prevent progression. The pillars are tight blood pressure and blood sugar control, specific medicines that reduce protein leak and protect the filters, avoiding kidney-irritating medicines (particularly certain painkillers), dietary adjustments tailored to the stage (salt, and in later stages protein, potassium and phosphorus), and treating the underlying cause. Anaemia and bone-mineral issues are addressed as they arise. Regular monitoring confirms stability or signals the need to intensify treatment.

Follow-up and monitoring

The frequency of monitoring depends on the stage and risk — from yearly for very early changes to every few months for established disease. Each visit re-checks kidney function, urine ACR, blood pressure and metabolic markers. See Kidney Health Monitoring for the schedule. Where disease is advanced or progressing despite treatment, timely referral for specialist kidney care is arranged.

Warning signs — seek prompt care

• Markedly reduced urine output or no urine for a day.
• Rapidly worsening swelling with breathlessness.
• A sudden, large rise in creatinine on testing.
• Persistent nausea, vomiting, itching or drowsiness with known CKD.
• Very high or hard-to-control blood pressure with kidney abnormalities.
