SUMMARY. The aim – to monitor the dynamics of changes in views on obesity, to analyze the global experience in the search for effective treatment for this disease of the last decade.
Material and Methods. The systematic analysis was provided by using search engines of scientific information, in particular PubMed, Medscape, ScienceDirect, Google Scholar, UpToDate. The method of information search and analytical-comparative method are applied.
Results. Obesity is associated with numerous complications: metabolic, mechanical, mental. It has been proven that life expectancy decreases with an increase in BMI.
BMI is the most useful indicator of overweight and obesity because it is the same for both sexes and for all age groups of adults.
Losing weight by 5–10 % of the initial amount reduces the incidence of type 2 diabetes, cardiovascular mortality, leads to improvement of blood lipid profile, normalization of blood pressure, reducing the severity of obstructive sleep apnea and improving health-related quality of life.
Obesity has a huge impact on life expectancy. It is estimated that almost 80 % of people who had a normal BMI at the age of 35 will live to be 70 years old; however, with a BMI of 30–35 kg/m2, this share decreases to about 70 %; with a BMI of 35–40 kg/m2 up to approximately 62 %; with a BMI of 40–50 kg/m2 only a half of assessed people live to 70 years old.
Weight decrease by 5–10 % is the cause of a significant clinical effect in the following pathological conditions: osteoarthritis, urinary incontinence, gastroesophageal reflux disease, polycystic ovary syndrome.
Conclusions. Obesity, as defined by the Association of Obesity Medicine, is indeed a chronic, relapsing, multifactorial, neurobehavioral disease in which increased body fat contributes to adipose tissue dysfunction and abnormal physical strength of adipose mass, leading to adverse metabolic, biomechanical, and psychosocial consequences for the body. Even a slight decrease in body weight reliably improves the patient’s general condition, positively affects the course of concomitant diseases, improves laboratory parameters and extends the patient’s life expectancy. It has been proven that only a combined individual approach to the patient with the latter’s active involvement in the treatment gives a positive and, what is the most important, long-lasting effect.
