Nephrologist

What this life looks like

The kidneys filter 200 litres of blood every day, regulate blood pressure, balance the body's fluids and electrolytes, and produce hormones that control red blood cell production. When they fail, every other organ system is affected. As a Nephrologist you specialise in the prevention, diagnosis, and treatment of kidney disease – from hypertension-related chronic kidney disease to glomerulonephritis, to acute kidney injury in critically ill patients, to end-stage kidney failure requiring dialysis or transplantation. Kidney disease in Africa is largely invisible. It does not have the global profile of HIV, malaria, or tuberculosis – yet it affects an estimated 15 percent of adults across sub-Saharan Africa, most of them undiagnosed. The leading drivers – hypertension, diabetes, HIV kidney disease, and infections including schistosomiasis and malaria – are all common in Africa. Yet Africa has fewer than 0.5 nephrologists per million people, dialysis is unaffordable for the vast majority of patients who need it, and kidney transplantation is available in only a handful of African cities. The nephrologist who works in Africa is addressing a massive unmet need with very limited tools – and pushing to build more.

What she actually does

A Nephrologist diagnoses and manages chronic kidney disease, acute kidney injury, glomerulonephritis, hypertension-related kidney disease, diabetic nephropathy, and kidney disease associated with HIV and infections. They manage patients on haemodialysis and peritoneal dialysis, assess and prepare patients for kidney transplantation, and work with transplant teams post-transplant. They also run hypertension clinics, advise on fluid and electrolyte management in critically ill patients, and screen high-risk populations for early kidney disease.

Where you can work

Why it matters in Africa

Hypertension – the most common cause of kidney failure – affects over 130 million Africans. Diabetes, another leading cause, is rising rapidly. HIV-associated nephropathy remains common in Africa despite antiretroviral treatment. Yet most Africans with chronic kidney disease are diagnosed only when they reach end-stage failure – at which point treatment options are extremely limited and expensive. Building nephrology capacity for earlier detection and treatment is essential to preventing the rising wave of kidney failure that Africa's epidemics of hypertension and diabetes will otherwise produce.

Your pathway in

Biology, Chemistry, and Mathematics at secondary school. Then MBBS or MBChB over five to six years, followed by housemanship. Internal medicine residency then subspecialty fellowship in nephrology through the West African College of Physicians or equivalent body follows. The full pathway takes approximately 12 to 14 years.

Skills you will need

Technical: Kidney disease management, fluid and electrolyte management, dialysis including haemodialysis and peritoneal dialysis, immunosuppression management for transplant patients, renal biopsy, and renal imaging interpretation. Human: Managing patients with progressive, often terminal disease with honesty and compassion, the ability to counsel patients and families on the realities of dialysis and transplantation in resource-limited settings, and the advocacy instinct to fight for better kidney care policies in contexts where renal care is severely underfunded. Digital tools: Electronic renal records, dialysis monitoring systems, kidney disease management apps, and telemedicine for remote nephrology consultation.
