Professor Ademilola Adetuyibi stands as a towering figure in Nigerian and international medicine, a distinguished physician, endocrinologist, and academic whose career spanned decades of dedicated service, groundbreaking research, and profound pedagogical influence. Born on 24 September 1938 in Ghana to a Nigerian merchant father, John Adebiyi Adetuyibi, he held Nigerian nationality and embarked on an academic journey that would take him from Nigeria’s premier institutions to the halls of Cambridge University, solidifying his reputation as a scholar of exceptional calibre.
Adetuyibi’s early education began in Ghana at the Presbyterian Infant School, Aburi (1943–1945), before continuing in Nigeria at Christ Church School, Mapo, Ibadan (1946–1951). He proceeded to complete his secondary education at Oduduwa College, Ile-Ife (1952–1956). This solid academic foundation prepared him for a remarkable medical career, which commenced at University College, Ibadan/University of Ibadan (UI), where he was an undergraduate from 1958 to 1965, completing his professional training at the University College Hospital (UCH), Ibadan. He further augmented his credentials with postgraduate studies at the University of Cambridge, England (1970–1972).
His academic achievements were formally recognised through a formidable array of qualifications, including the MB BS (Ibadan) in 1965, a PhD (Cantab) in 1972 an MD (Lond) in 1977. His professional excellence earned him fellowships such as MRCP (Lond) in 1968, FRCP (Lond) in 1980, FMCP (Nig) in 1981, and FWACP in 1981, marking him as an exceptionally well-qualified specialist.
Professor Adetuyibi’s professional life was deeply rooted in the University of Ibadan and the University College Hospital (UCH). After his qualification, he held house jobs and registrar posts at UCH from 1965 to 1970. His commitment to public service was also evident in his brief but significant tenure with the Armed Forces Medical Services of Nigeria in early 1969, where he attained the rank of Major in the Nigerian Army, serving until 1970.
He rapidly ascended the academic ladder at the University of Ibadan, starting as a lecturer in medicine in 1973, becoming a senior lecturer in 1975, and achieving the full professorship of medicine in 1977. He retired from the University of Ibadan as professor of Medicine and honorary consultant physician/endocrinologist to UCH in September 1996.
His leadership extended beyond the lecture theatre. He served as the head of the Department of Medicine (1980–1982) during a rotational period and was the master of Tedder Hall at the University of Ibadan for two terms (1977–1980/1982–1987). Notably, he instituted innovative departmental publications, including a departmental newsletter and occasional publications. His reputation as an expert led to numerous external roles, including acting as an external examiner in medicine to medical schools across Nigeria (Lagos, Benin, Zaria, and Shagamu) and to the University of Zimbabwe. He also sat on interview panels as an expert assessor for professorial appointments at the Universities of Lagos and Benin.
Professor Adetuyibi was a dedicated scientist and endocrinologist, known for his specialization and research focus on diabetes and its complications. His doctoral research at Cambridge was pioneering; he developed the first radioimmunoassay technique for the estimation of kininogenase (kallikrein) in urine in Professor Ivor H. Mills’ laboratory. This significant contribution to endocrinology followed his careful work on the kinetics of the kininogenase-kininogen reaction in homologous plasma.
His scientific output is documented in several important papers published in prestigious journals like The Lancet and Tropical and Geographical Medicine. Key research themes include:
Kallikrein-Kinin System: Exploring the relationship between urinary kallikrein, renal function, hypertension, and the excretion of sodium and water.
Diabetes in the African Context: Authored papers such as "Diabetes in the Nigerian African. I. Review of long-term complications" and "Insulin secretory reserve in diabetic Nigerian Africans," and co-authored studies on the risk factors and outcome of treatment for foot lesions in Nigerian diabetic patients.
Cardiology: Research on chronic pulmonary heart disease and P-wave patterns in endomyocardial fibrosis in Ibadan.
Beyond his scientific papers, he made a substantial contribution to medical literature through several books, aimed at both academic and lay audiences. His seminal work, Companion to clinical medicine in the tropics (London, Macmillan, 1980), became a core textbook for undergraduate and postgraduate students. Other publications included Diabetes Mellitus. A handbook for the lay public and paramedical personnel and Medicine Through Multiple Choice Questions (MCQs).
Following his retirement from Ibadan, Professor Adetuyibi leveraged his expertise on the global stage, holding multiple consultant physician appointments in the Middle East, including consultant physician, King Abdulaziz Hospital & Oncology Center, Jeddah, KSA (1991–1995), consultant physician, Al-Sabah Hospital, Kuwait (1996–1998), and consultant physician, North West Armed Forces Hospital, Tabuk, KSA, until December 1999.
In his personal life, Professor Adetuyibi was married in 1966 to Atinuke Olabisi née Omigbodun, the daughter of a clergyman and teacher. They had two sons, one named Adeoye, and a daughter. Outside of medicine, he was known to read widely and had a deep personal interest in African works of art, building a significant collection.
Professor Ademilola Adetuyibi's legacy is one of unwavering academic rigour, clinical excellence, and deep commitment to education. From his pioneering research on the kallikrein-kinin system to his foundational medical textbooks and his leadership roles at the University of Ibadan, he profoundly shaped medical practice and education in West Africa and beyond. His life exemplifies a distinguished physician who successfully balanced a demanding academic and clinical career with pioneering scientific investigation and a rich personal life, leaving an indelible mark on all who had the privilege of learning from or working with him.
