Obesity and overweight are not just cosmetic defects associated with excess body fat. Obesity is a multifactorial chronic relapsing disease requiring a skilled medical intervention. This condition is associated with other pathologies: high blood pressure, atherosclerosis, type II diabetes, cancer and other processes.

Currently, according to the World Health Organization (WHO) obesity is a new chronic “epidemic” of our time. More than 300 million of patients suffering from this disease were registered all over the world. In economically developed countries (including the USA), 10 – 40% of the population suffers from obesity.

There is a dangerous tendency – an increase in the number of children and adolescents suffering from overweight or obesity. At present, in the developed countries up to 30% of adolescents are overweight, and 15% – obese.

It has been proven that overweight in childhood is the cause of obesity in adulthood: 45% of children who are overweight at 5 years of age suffer from obesity having grown up.

If obesity is observed in young people, the risk of its development increases to 75% in middle age. WHO experts predict that the percentage of obese or overweight people will increase 2-fold by the year 2025 compared with 2000.

Statistical data show the important role of demographic factors such as gender, age, and ethnicity in the genesis of obesity development. Thus, the incidence of overweight in women higher than in men. The number of patients with obesity increases with age.
