Chronic Kidney Disease in Nigeria

Q: How common is CKD in Nigeria?

Estimated 25–30 million Nigerians have CKD — approximately 14% of the adult population. Most are undiagnosed. The primary causes are hypertension (50%) and diabetes (25%). Herbal medicine nephrotoxicity and sickle cell disease are also significant in Nigeria.

Q: Can CKD be reversed?

Truly chronic kidney damage (scarred tissue) cannot be reversed. However, progression can be dramatically slowed with optimal management — many people with CKD Stage 3 live for decades without reaching dialysis. Early detection is critical.

Q: Is herbal medicine safe for people with kidney disease?

No — many traditional herbal preparations used in Nigeria are nephrotoxic. Aristolochic acid (in some herbs) causes irreversible kidney damage. Agbo jedi-jedi and various local concoctions have been documented causes of CKD in Nigerian patients. Once you have CKD, all traditional medicines must be reviewed with your nephrologist.

Q: How expensive is dialysis in Nigeria?

Haemodialysis costs approximately N30,000–N60,000 per session (3 sessions/week), equating to N400,000–N800,000 per month. This is unaffordable for most Nigerians without HMO or NHIA support. Prevention of kidney failure is economically as well as medically critical.

Q: Can I get a kidney transplant in Nigeria?

Yes — kidney transplantation is performed at Lagos University Teaching Hospital, Aminu Kano Teaching Hospital, University College Hospital Ibadan, and other centres. The number of transplants performed is limited by donor availability and cost. Living-donor transplants from a compatible family member are the most accessible option.

Nigeria's silent kidney disease epidemic — detection and management

Chronic kidney disease (CKD) affects an estimated 25 million Nigerians — yet most have no idea. CKD has no symptoms until the kidneys are functioning below 30% of normal capacity. The main drivers are hypertension and diabetes — Nigeria's two most common non-communicable diseases. Caught early, CKD can be slowed significantly; caught late, it progresses to dialysis or death.

Signs and Symptoms

✓ Most CKD is SILENT until advanced stages

✓ Fatigue and weakness (anaemia from kidney failure to make erythropoietin)

✓ Swelling in legs, ankles, and around the eyes (fluid retention)

✓ Reduced urine output or foamy urine (protein in urine)

✓ High blood pressure that is difficult to control

✓ Nausea, vomiting, and poor appetite (advanced CKD)

✓ Shortness of breath (fluid in lungs or anaemia)

✓ Itching all over the body (uraemia)

✓ Confusion and drowsiness (very advanced — uraemic encephalopathy)

Risk Factors

Hypertension — the leading cause of CKD in Nigeria
Diabetes mellitus
Recurrent urinary tract infections
Kidney stones
Sickle cell disease — causes sickling in kidney vessels
HIV-associated nephropathy
Chronic NSAID use (ibuprofen, diclofenac — very common in Nigeria)
Herbal medicine nephrotoxicity — agbo, certain plants used as traditional remedies
Family history of kidney disease

When to Seek Help

Hypertension or diabetes diagnosedBoth conditions require annual kidney function tests (creatinine, eGFR, urine protein) — even with no symptoms.

Foamy urinePersistent foamy urine suggests protein loss — an early warning sign of kidney damage.

Leg swelling with known diabetes or hypertensionMay represent nephrotic syndrome or CKD-related fluid retention — requires urgent assessment.

Urine output reduced significantlyOliguria (producing less than 500 ml urine daily) is an emergency in CKD — may represent acute decompensation.

Tests & Diagnosis

🧪 Serum creatinine + eGFR

eGFR (estimated glomerular filtration rate) calculated from creatinine, age, and sex — the primary measure of kidney function. Normal >90; stage 5 (kidney failure) <15 ml/min.

🧪 Urine albumin-to-creatinine ratio (ACR)

Detects protein in urine — the earliest marker of diabetic and hypertensive kidney damage. ACR above 3 mg/mmol indicates significant proteinuria.

🧪 Urine dipstick

Detects blood and protein in urine — quick screening test.

🧪 Kidney ultrasound

Shows kidney size and structure — small kidneys suggest chronic disease; asymmetry suggests obstruction or renovascular disease.

🧪 Full blood count

Anaemia of CKD is normocytic, normochromic — caused by reduced erythropoietin production.

🧪 Serum electrolytes (potassium, bicarbonate)

Hyperkalaemia (high potassium) and acidosis are dangerous complications of advanced CKD requiring urgent management.

Treatment Options

Control blood pressure strictly

Target BP below 130/80 mmHg. ACE inhibitors (lisinopril) or ARBs (losartan) are the preferred antihypertensives in CKD — they also reduce proteinuria and slow disease progression independently of BP control.

Control blood sugar tightly

In diabetic CKD, SGLT2 inhibitors (empagliflozin, dapagliflozin) have proven kidney-protective effects beyond glucose lowering — now first-line in diabetic CKD.

Reduce proteinuria

ACE inhibitors/ARBs reduce protein leakage — a key mechanism of slowing CKD progression.

Avoid nephrotoxins

Stop all NSAIDs (ibuprofen, diclofenac, aspirin for pain). Avoid herbal preparations (many are nephrotoxic). Report all medications to your nephrologist. Contrast dye for CT scans requires pre-hydration — inform the radiologist of your CKD.

Dietary modification

Reduce salt (reduces proteinuria and BP). Limit potassium in Stage 4–5 (avoid bananas, avocados, potatoes in large amounts). Moderate protein restriction in advanced CKD (nephrologist guidance). Adequate hydration — but not excessive in advanced CKD.

Treat anaemia of CKD

Iron supplementation if iron-deficient. Erythropoiesis-stimulating agents (EPO injections) for anaemia when eGFR is low — available in Nigeria.

Dialysis (Stage 5 CKD — eGFR <10–15)

Haemodialysis (3 sessions per week at a dialysis centre) or peritoneal dialysis (done at home daily). Kidney transplant is the best long-term option — available at some Nigerian teaching hospitals.
