The definition of an infected human obesity, is the man who owns the fatty tissue and the value of body mass index (BMI) has over 30. The BMI is an index measuring weightcompared with height. You may have excess adipose tissue, serious health consequences, such as diabetes, high blood pressure and high levels of lipids in the blood.
Obesity is one of the most common medical conditions in Western society today, the most difficult in terms of the treatment of obesity. Not, relatively speaking, achieved little progress in the treatment of obesity (except lifestyle change), but many were gathering information about the medical consequences of obesity status.
Causes and risk factors of obesity
Obesity was until recently associated with the lifestyle of lazy (sitting) and excess consumption of calories. But today, it is known that obesity causes this task, but there are also genetic factors play a role in the different incidence of obesity.
As proof, I have adopted children see plumper style corresponds to the pattern that we are seeing their parents biologists, more that we see to the adoptive parents. The research also showed the twins identical, having the effect of genetic factors on the body mass index is greater than the impact of environmental factors.
The estimate is that it could be attributed because between 40%-70% of hereditary factors, obesity, and not the environmental factors or lifestyle.
The research also showed that mice, five genes linked to appetite, these genes lead to obesity. These genes are present also in humans. One of the key genetic factors in obesity, is hormone leptin (Leptin).
Today, believe that obesity is a combination of specific genes, not only as a result of a defect in a single gene. The increase in obesity in recent decades, primarily due to environmental influence, such as lifestyle and dietary habits.
