The prevalence of obesity is now one of the main concerns of public health worldwide. Obesity leads to various otolaryngological (ENT) problems by altering the immune system, studies are showing a positive correlation between obesity and common otolaryngological diseases. Following the studies carried out so far, it has been shown that bariatric surgery is currently the most effective and long-lasting treatment for severe obesity. Gastric bypass and other weight loss surgeries - known collectively as bariatric surgery - involve making changes to the digestive system to help the patient lose weight. The present study highlights significant weight loss between approximately two years and six years, and the highest percentage is of patients who have lost more than 50 kg through bariatric surgery, and aims to explore the benefits or risks of bariatric surgery in the ENT field. The purpose of the research is to deepen and research the ENT manifestations following bariatric surgery.
