Non-communicable diseases are now the leading cause of death worldwide, reflecting a shift in global health from infectious diseases to conditions linked to lifestyle and long-term behaviour.
Diseases such as Type 2 Diabetes, heart disease and certain cancers are increasingly associated with diet, physical inactivity and environmental factors.
Health experts say urbanisation and modern lifestyles have contributed to rising rates of obesity and related conditions. Processed foods, sedentary work and reduced physical activity are among the key drivers.
At the same time, healthcare systems are facing the challenge of managing chronic conditions that require long-term treatment rather than short-term intervention.
Governments are introducing measures aimed at prevention, including public health campaigns, taxes on sugary drinks and efforts to promote healthier lifestyles.
However, changing behaviour at a population level remains difficult. Social and economic factors often influence health choices, making it harder for individuals to adopt healthier habits.
There is also growing interest in using technology to address these challenges. Wearable devices, health apps and personalised nutrition programmes are being promoted as tools to support healthier living.
Experts say tackling lifestyle diseases will require a combination of policy, education and individual action.
As global health priorities continue to evolve, prevention is becoming as important as treatment — and in some cases, even more so.
