Obesity is one of the leading public health problems in the world, with its frequency of pandemic proportions. It is defined as an excessive accumulation of body fat in the body and an index of body mass above 30 kg/m2. According to the World Health Organization's latest data, more than 650 million adults worldwide suffer from obesity, accounting for 13% of the world's population. Obesity is a complex phenomenon and is explained by the interaction of genetic and environmental factors, the most significant of which is irregular nutrition and insufficient physical activity. Obesity is one of the major risk factors for the development of many diseases. Many studies confirm that there is a clear link between obesity and type 2 diabetes, arterial hypertension, cardiovascular disease, dyslipidemia and depression. As the number of people suffering from obesity increases, so does the number of patients suffering from comorbidities as well, and it is therefore important to prevent and treat obesity. Family physicians are the ones who are familiar with the illnesses and habits of their patients and that plays an important role in this. Each patient should be accessed individually, explained to about what obesity is and what comorbidities are and then suggested and supported in the therapy. The most important step is a lifestyle change that includes body mass reduction and increased physical activity, and if necessary, pharmacological and, exceptionally, surgical therapy can be introduced.
