There are several factors that have contributed to the rising prevalence of diabetes, hypertension, obesity, and hypercholesterolemia in India. Here are some of the primary reasons:

• The adoption of a sedentary lifestyle and unhealthy eating habits leading to high-calorie consumption and less physical exertion
• The lack of safe drinking water in rural areas, leading to water-borne diseases, especially in coastal and hilly areas.
• The increased intake of salt and sugar in the diet, which leads to elevated blood pressure and increased cholesterol levels respectively.
• The lack of awareness and accessibility of preventive healthcare facilities in the country.
• The individual's genetics is a major contributing factor, which affects the susceptibility and severity of all non-communicable diseases.
• The inadequate investment in public healthcare, leading to inadequate coverage of the population and a lacking supply of medical facilities.

These factors have led to a significant increase in the prevalence of non-communicable diseases in India, and unless the government takes appropriate measures to address them, the situation is unlikely to improve in the near future.
