Today, there is not much difference between tier 1 and tier 2 cities, with cities witnessing a massive transition in living with stressful and unhealthy lifestyles being prevalent. This has caused numerous diseases in tier 1 cities, such as non-communicable diseases like cardiovascular disease, neuro-related diseases, asthma, cancer, diabetes, depression, and infectious diseases such as HIV/AIDS, tuberculosis, pneumonia, dengue, etc. In tier-II cities, too witnessing transition in lifestyles, diseases such as hypertension, diabetes, blood pressure, high cholesterol, etc., are more prevalent.
