Obesity is recorded as a rapidly increasing and very serious public health issue across the globe. According to data from the World Health Organization (WHO), more than one billion people worldwide are living with obesity. Approximately 880 million of them are adults, and 159 million are children. Since 1990, obesity rates have more than doubled among adults and have quadrupled among children and adolescents. If this trend continues, it is projected that by 2035, half of the world’s population—around 4 billion people—will be overweight or obese. Obesity can lead to serious health problems such as cardiovascular diseases, diabetes, and certain types of cancer. Therefore, promoting healthy eating habits and increasing physical activity are of great importance in the fight against obesity. For those who cannot lose weight despite following all these criteria, obesity surgery comes into consideration.
