Nigeria continues to face one of the world’s lowest life expectancies, with health experts warning that millions of citizens are dying years, and in many cases decades, before their expected lifespan because of preventable causes ranging from poor healthcare access and poverty to late diagnosis of diseases and unhealthy lifestyles.
Medical professionals, public health specialists and policy analysts say the country’s life expectancy crisis is not driven by a single factor but by a combination of weak healthcare infrastructure, economic hardship, infectious and non-communicable diseases, environmental pollution, insecurity and inadequate government investment in the health sector.

According to recent global estimates, Nigeria’s average life expectancy is approximately 54 to 55 years, placing it among the countries with the shortest life expectancy worldwide. Experts argue that this statistic reflects years of systemic failures rather than biological limitations. (ICIR News)
Preventable deaths remain widespread
Health professionals say many Nigerians continue to die from diseases that are either preventable or treatable if detected early.
Communicable diseases such as malaria, tuberculosis and HIV/AIDS remain major contributors to mortality, while non-communicable diseases including hypertension, diabetes, stroke, kidney disease and cancer are increasing rapidly across the country.
Unfortunately, many patients only seek medical attention after their conditions have become severe, reducing the chances of successful treatment.
Medical experts attribute delayed hospital visits to poverty, self-medication, cultural beliefs, fear of medical costs and inadequate awareness about early symptoms of diseases. (Vanguard News)
Poverty continues to determine survival
Economic hardship has become one of the strongest predictors of health outcomes in Nigeria.
Millions of households struggle to afford nutritious food, clean drinking water and quality healthcare. As inflation continues to affect household incomes, many families postpone hospital visits or discontinue treatment because they cannot pay medical bills.
Unlike many developed countries where health insurance significantly reduces treatment costs, healthcare spending in Nigeria remains largely out-of-pocket, leaving vulnerable citizens exposed to catastrophic medical expenses. (Wikipedia)
Healthcare infrastructure under pressure
Experts say Nigeria’s healthcare system remains overstretched.
Many primary healthcare centres lack essential drugs, modern diagnostic equipment and adequate medical personnel. Rural communities are particularly affected, with residents often travelling long distances before reaching hospitals capable of handling emergencies.
The shortage of specialist doctors has also worsened due to the migration of healthcare workers seeking better salaries and working conditions abroad.
This “brain drain” has reduced the country’s capacity to deliver quality healthcare, increasing waiting times and reducing access to specialised treatment. (Wikipedia)
Lifestyle diseases are increasing
Doctors are also raising concerns over changing lifestyles among Nigerians.
Poor diets rich in processed foods, physical inactivity, excessive alcohol consumption, smoking, chronic stress and inadequate sleep have contributed to rising cases of hypertension, obesity, diabetes and cardiovascular diseases.
Public health specialists warn that these illnesses often develop silently for years before symptoms become obvious.
Routine medical screening, they say, remains uncommon among many Nigerians, allowing diseases to progress unnoticed.
Maternal and child mortality
Nigeria continues to record some of the world’s highest maternal and under-five mortality rates.
Experts note that many women still deliver without skilled birth attendants, while preventable childhood illnesses such as pneumonia, diarrhoea and malaria continue to claim thousands of young lives annually.
Improving antenatal care, immunisation coverage and emergency obstetric services could significantly improve life expectancy nationwide.
Mental health receives little attention
Mental health professionals also argue that psychological wellbeing has been neglected.
Depression, anxiety and stress-related disorders are becoming increasingly common due to unemployment, insecurity and economic hardship.
Yet access to mental healthcare remains limited because of inadequate facilities, shortage of specialists and persistent social stigma surrounding mental illness.
Experts believe untreated mental health conditions indirectly contribute to premature deaths through substance abuse, suicide and worsening physical illnesses.
Environmental factors
Air pollution, poor sanitation, unsafe drinking water and inadequate waste management continue to expose millions of Nigerians to preventable diseases.
Urban residents face increasing exposure to industrial pollution and traffic emissions, while many rural communities still lack access to clean water and proper sanitation facilities.
Environmental health specialists warn that these conditions increase respiratory diseases, gastrointestinal infections and other chronic illnesses that shorten lifespan.
Insecurity affects healthcare delivery
Persistent insecurity across parts of Nigeria has also disrupted healthcare delivery.
Armed conflicts, kidnappings and displacement have forced many health facilities to close or reduce operations in affected communities.
Humanitarian organisations report that millions of internally displaced persons have limited access to healthcare, nutrition and clean water, increasing vulnerability to disease outbreaks.
Experts call for urgent reforms
Health professionals say improving Nigeria’s life expectancy requires comprehensive reforms rather than isolated interventions.
Among their recommendations are increased government investment in healthcare, rehabilitation of public hospitals, expansion of health insurance coverage, improved remuneration for healthcare workers, stronger disease prevention programmes and greater public awareness on healthy living.
They also advocate increased funding for primary healthcare, wider access to routine medical screening, improved maternal and child healthcare services, enhanced vaccination campaigns and policies that address poverty, unemployment and environmental pollution simultaneously. (Vanguard News)
A national development challenge
Public health experts argue that life expectancy is more than a health indicator—it reflects the overall quality of governance, economic opportunity and social wellbeing.
They warn that unless Nigeria strengthens its healthcare system while addressing poverty, insecurity and environmental challenges, millions of citizens will continue to die prematurely from preventable causes.
For experts, extending the average Nigerian’s lifespan is not only about keeping people alive longer but ensuring they live healthier, more productive lives supported by accessible, affordable and quality healthcare. (ICIR News)
