Dr Stella Alagbe

Dr. Stella Chinyelu Alagbe is a graduate of the prestigious University of Cape Town (UCT) in South Africa. She trained under Professor Brian Rayner and Professor Charles Swanepoel  whose relentless supervisions guided Her to complete a Masters of Philosophy certification in Nephrology as a well  as a Certificate in Nephrology (South Africa).

The Division of Nephrology and Hypertension at UCT utilizes a curriculum that effectively integrates knowledge of Novel research methodologies and Research outcomes. These are then used in formulations of Clinical approaches to patient care in Nephrology. Furthermore, the diversities seen in the geo-ethnicities and socio-economic backgrounds of participants in Research protocols and Clinical training, helps greatly in Her current position as a Clinician in the highly heterogeneous, multicultural urban population of Lagos, Nigeria. 

Her journey into this career path in the field of Medicine started from the University of Benin, Benin City Nigeria where she obtained the Bachelor degree in Medicine and Surgery (M.B.B.S). She later continued on this career path by completing a Masters Program in Public Health (MPH) at the University of Lagos, Nigeria. Upon completion of this program, Dr. Stella Alagbe joined the team of Clinicians at Life Support Medical Center, a private Nephrology Center in Lagos. This is where her interest in the field of Nephrology was kindled. She later enrolled in the Post graduate program in Internal medicine and Nephrology at the College of Medicine of the University of Lagos - thus leading to her graduation as a Fellow of West African College of Physicians.

Currently, Dr. Stella Alagbe is a Licensed Consultant Nephrologist with the Nigerian Medical Council. She is the Head of Nephrology and Dialysis Unit at the General Hospital in Marina Lagos, Nigeria.
