Lifestyle is simply the way of life. The physical, mental, and social well-being of a human is hugely affected by his lifestyle. Lifestyle diseases are mostly diseases we bring to ourselves because of the way we live, eat, work, and go about our everyday lives. Lifestyle diseases are non-communicable and are caused by lack of physical activity, unhealthy eating, alcohol, drug use disorders, smoking tobacco, etc. An unhealthy lifestyle mostly results in the development of lifestyle diseases, specifically heart disease, stroke, diabetes, obesity, metabolic syndrome, chronic obstructive pulmonary disease, and some types of cancer.

What are the Most Common Lifestyle diseases?

According to WHO, 60% of related factors to individual health and quality of life correlate to lifestyle. Poor diet and its consequences like obesity are one of the common health problems in urban societies. It is estimated that more than 36% of the world population is overweight or obese. Around 32.6 percent of both men and women in the United States self-report that they are obese, compared to 14.6 percent of women and 18.1 percent of men in Germany. The rates of obesity can differ drastically from country to country as various factors like income, activity level, diet, stress, and work environment affect the rate of obesity.

The world is undergoing some drastic changes due to globalization and urbanization. These processes have an impact on the health and lifestyle of society. Local cuisines and tastes are on the verge of extinction, and more and more processed food items are getting a place on our menu. Also, the increase in physical inactivity due to the increasingly desk-bound nature of our work, changing modes of transportation, increasing urbanization, rising income, and higher women’s labor force participation, etc. have caused a surge in the rate of obesity and overweight. In today’s world, the number of people killed due to being underweight is less compared to the number of people who are overweight or obese. The most common lifestyle diseases are;


Hypertension/ High Blood Pressure

Heart disease and Stroke

Type 2 Diabetes

chronic respiratory diseases
