Why More Young Nigerians Are Suffering Strokes, Doctors Warn

A growing number of young Nigerians are being struck by strokes, a condition once thought to affect mainly the elderly, medical experts have warned. Doctors say the alarming rise in cases among people in their 20s and 30s is being fueled by poor lifestyle habits, environmental risks, and underlying but undetected health conditions.

Specialists who spoke to Punch Healthwise identified high blood pressure, high cholesterol, obesity, diabetes, smoking, stress, poor diets, alcohol consumption, and physical inactivity as the main culprits. Many of these risk factors remain silent until a stroke occurs, making early screening and prevention critical.

They also highlighted the role of genetic and medical conditions such as sickle cell disease, congenital heart defects, migraines, HIV, and pregnancy-related complications, which combine with unhealthy lifestyles to increase the risk.

According to the World Health Organisation (WHO), stroke is one of the leading causes of death and disability worldwide, with 15 million cases annually. Five million victims die, while another five million are left permanently disabled. WHO reports that stroke is rare in people under 40, but when it occurs, high blood pressure is often the primary cause.

Nigeria is facing an escalating crisis. The National Institute of Health estimates stroke prevalence in the country at 1.14 per 1,000 people, with a 30-day fatality rate as high as 40 percent. Findings from the Stroke Investigative Research and Education Network (SIREN) study reveal that poor diet, stress, and low physical activity are major drivers, while genetic factors such as sickle cell disease compound the risks.

Professor Mayowa Owolabi, Director of the Center for Genomic and Precision Medicine at the University of Ibadan, warned that stroke and other cardiovascular diseases have overtaken infectious diseases as Africa’s leading killers. He pointed to hypertension, obesity, smoking, and poor nutrition as major triggers, while stressing that daily consumption of green vegetables, regular exercise, and early detection of silent conditions like high blood pressure could significantly reduce risks.

“Most risk factors show no symptoms until a devastating stroke happens. That is why screening and control across the life course is crucial,” he said. Owolabi called for urgent policy interventions, including reintroducing physical activity in schools, taxing unhealthy products like tobacco and alcohol, and using such funds to promote healthier food options and safer environments.

Consultant neurologist Dr. Demola Olaniyi echoed these concerns, warning that traditional stroke risk factors, once confined to older adults, are now widespread among people in their 20s and 30s. He noted that hypertension remains the single most devastating culprit, but added that migraine, oral contraceptive use, pregnancy, congenital heart conditions, HIV, and drug use also raise risks in younger people.

Olaniyi urged Nigerians to learn stroke warning signs using the F.A.S.T. rule—Face drooping, Arm weakness, Speech difficulty, and Time to call emergency services. “Stroke can be reversed if patients get to the hospital within 4.5 hours, but many arrive too late due to poor awareness and delays,” he said. He called for better emergency response systems, more stroke care centers, and investment in advanced treatments such as clot-busting drugs and mechanical thrombectomy.

A major regional study by SIREN, which analysed over 2,000 cases in Nigeria and Ghana, found that nearly one in four stroke patients in West Africa is under 50. Hypertension accounted for almost 89 percent of these cases. Unlike in Western countries where ischemic stroke is more common in the young, over half of the West African patients suffered from the deadlier hemorrhagic type, caused by bleeding in the brain.

The study also linked low education and poor health literacy to higher stroke risks, raising concerns about late detection and mismanagement of hypertension in many communities. Globally, stroke in people under 50 accounts for 5 to 20 percent of cases. In West Africa, however, the numbers are climbing rapidly, prompting experts to warn of an “epidemiological time bomb.”

Unless urgent action is taken to improve public awareness, expand hypertension screening, encourage healthier lifestyles, and ensure affordable access to care, doctors fear the country may continue to lose large numbers of its young and productive workforce to a disease that is largely preventable.
