What is lifestyle disease?

Possible diseases due to our living & working lifestyle include:

A number of factors influence the way in which sport and physical activity impacts on health in different populations. Sport and physical activity in itself may not directly lead to benefits but, in combination with other factors, can promote healthy lifestyles. There is evidence to suggest that changes in the environment can have a significant impact on opportunities for participation and in addition, the conditions under which the activity is taking place can heavily impact on health outcomes. Elements that may be determinants on health include nutrition, intensity and type of physical activity, appropriate footwear and clothing, climate, injury, stress levels and sleep patterns.

Cancer is one such disease where life style contribute much.

People ignoring the habits of our elders with respect to eating habits, exercising habits, drinking habits, etc. They knew well, but chose to adopt different habits that brought them eventually cancer in many different organs, like lung, stomach, intestine, liver, etc.

In developing countries like India, the greatest burden of disease is due to communicable diseases, malnutrition and complications of pregnancy and childbirth. As developing countries grow, they are likely to experience an epidemiological transition from communicable to non-communicable diseases. Developing countries will have to deal with the ground realities of limited resources entwined with the dual burden of infectious and chronic diseases. Thus, preventing lifestyle and chronic diseases is a vital investment, particularly for developing countries like India.

Dear Colleagues,

Good Day,

"Lifestyle disease

Lifestyle diseases are defined as diseases linked with the way people live their life. This is commonly caused by alcohol, drug and smoking abuse as well as lack of physical activity and unhealthy eating. Diseases that impact on our lifestyle are heart disease, stroke, obesity and type II diabetes. The diseases that appear to increase in frequency as countries become more industrialized and people live longer. They can include Alzheimer's disease, arthritis, atherosclerosis, asthma, cancer, chronic liver disease or cirrhosis, chronic obstructive pulmonary disease, type 2 diabetes, heart disease, metabolic syndrome, chronic renal failure, osteoporosis, stroke, depression, and obesity. In the U.K the death rate is four times higher from respiratory disease caused by an unhealthy lifestyle

Some commenters maintain a distinction between diseases of longevity and diseases of civilization. Certain diseases, such as diabetes, dental caries and asthma, appear at greater rates in young populations living in the "western" way; their increased incidence is not related to age, so the terms cannot accurately be used interchangeably for all diseases.".......

Due to our standing & status in life we have become more lethargic in the sense that due to our heretic involvement , we do not give the enough time for the requirement of our health which demands a calm & quite life for few minutes . Our sleep without any disturbance ,problem of irritation  ,anger contemplation of our mind with rethinking process & such other action of our life, we do not give justice to our requisite health problem.

, Blood pressure,Heart Attack, Diabetes , Gastric trouble, Indigestion & stomach problem have become a order of day .

This is my personal opinion
