Non-communicable diseases (NCDs) include conditions such as cardiovascular disease, obesity, and allergies. NCDs are not transmitted between people but rather are caused by factors like age, genetics, unhealthy behaviors like smoking and poor diet, and air pollution. Key ways to prevent NCDs include maintaining a healthy diet, engaging in regular physical activity, avoiding tobacco and alcohol, and reducing pollution exposure. Treatment for NCDs should be available and affordable for all people according to the WHO. India still faces many issues related to the burden of NCDs as it continues developing.
