How does obesity occur? The reasons are complex. Despite popular opinion, morbid obesity is not purely the result of eating too much. According to recent studies, it has been found that cases of morbid obesity are often rooted in genetic causes. If this holds true in an individual's case, then dieting and exercise will have limited effects on the problem.
Scientific research in to the causes and cure for morbid obesity continues to be conducted all over the world. But until we gain a firmer grasp on all the implications of the disease, it is something that patients simply have to deal with and work on, oftentimes for their entire lives. Medical science has come up with numerous interventions, including surgery, but these are not cures for obesity – rather they provide relief for the physical strain and consequences that come from being excessively overweight.
We do not know what extreme obesity is caused by. Instead of there being one cause, it usually comes about as the result of several different factors, including diet, environment, genetics, heredity, and metabolism. Hypothyroidism and steroid intake are two medical conditions that might result in excessive weight gain or obesity.
Children whose parents are obese have a much greater chance of becoming obese themselves. Perhaps this has to do with genetic factors, but more often than not, it has to do with the family's sedentary lifestyle and eating habits. If parents do not take proper care of themselves, then their children can be born obese.
There are additional, environmental, factors that cause and maintain obesity.
