Causes of Non-communicable diseases

Cancer, diabetes, cardiovascular disease, and chronic respiratory conditions are the leading non-communicable diseases. The lack of physical activity, anomalies in the metabolism, a sedentary lifestyle, and the emergence of some cancers appear to be contributing factors in the development of NCDs.

Poor, less nutritive diets fall short of meeting one’s nutritional needs, and problems with sugar, salt, and fat consumption promote the emergence of non-communicable diseases. In addition, abusing alcohol and cigarettes increases the risk of cancer, lung disease, and metabolic disorders. Unsustainable ecosystem processes have an impact on bodily functions and lead to the emergence of certain diseases.
