Causes of Obesity
The three leading causes of obesity are genetic, environmental, and medical.
Genetic Factors: Generally, children of those who are obese tend to be obese. The genetic basis of obesity is difficult to establish, as it may also be environmental. However, there is a growing consensus that, in some cases, obesity may indeed be genetic.
Environmental Factors: Obesity can also result from environmental and social factors, as lifestyles and behaviors have changed over generations. A general decline in physical activity, combined with increased caloric intake, has led to greater societal weight gain. The world around us can be hectic, and we often don’t realize how many calories we consume, to the detriment of our health.
Medical Factors: Medical causes of obesity can stem from treatable diseases or from the side effects of certain medications. Hormonal changes and fluctuations may also trigger weight gain. Any of these may cause obesity.
