🧠 Modern Challenges
Antibiotic resistance: Overuse of antibiotics has caused bacteria to evolve resistance. MRSA (Methicillin-resistant Staphylococcus aureus) and C. difficile are leading examples. Some infections now untreatable with existing antibiotics. Could return us to pre-penicillin death rates from simple infections.
Lifestyle diseases: Obesity, type 2 diabetes, heart disease, and lung cancer are largely caused by diet, inactivity, smoking, and alcohol. Medicine can treat symptoms but cannot cure without behaviour change. Accounts for the majority of NHS spending.
Aging population: People living longer means more dementia, cancer, and chronic illness. The NHS was designed in 1948 for a population with shorter life expectancy. Funding and staffing under growing pressure.
Health inequalities: Life expectancy varies by up to 10 years between wealthy and deprived areas of the UK. Globally, treatments available in rich countries are inaccessible in poor ones. Progress in medicine does not automatically mean equal access.
