That obesity is one of the most common medical Cases  in world today, and the most difficult in terms of the treatment of obesity and response. No, achieve relatively little progress in the treatment of obesity (except for a lifestyle change), but has been collecting a lot of information about the medical consequences of obesity condition.


The causes and risk factors for obesity

Obesity has been until recently linked lazy lifestyle (depending on seating) and excess consumption of calories continuously. But today, known that these two factors are important to the incidence of obesity, but there are also different genetic factors play a role in obesity.


As evidence of this, the adoptive children to see the pattern of obesity is similar to the style that we see with both biological parents, more than we see in the adoptive parents. The research also showed had Identical twins, having the effect of genetic factors on body mass index (BMI) greater than the effect of environmental factors.

The estimate is that it can be attributed cause of between 40% - 70% of obesity to different genetic factors, not environmental factors or lifestyle.

The research also showed the mice, the presence of 5 genes linked to appetite, these genes that lead to obesity. That these genes are also present in humans. That one of the basic genetic factors in obesity, is a hormone (Leptin).


Believe today, that obesity is a mix of specific genes, not only as a result of a malfunction in a single gene. The increase in obesity in the past decades, due mainly to the environmental impact, such as lifestyle and dietary habits.
