Brief summary

Obesity has become a worldwide public health problem and severe obesity causes among other things, impaired quality of life above and beyond the impact of medical complications of the disease. Evidence links obesity with low self-esteem, poor body image, sexual dysfunction, and poor quality-of-life, while lifestyle changes and weight loss may improve these parameters. The aim of this study is to examine sexual function and overall quality of life among men with obesity. There is currently little known about the obesity-related health problems that are specific to Australian men, and we think it is likely that men have significant health concerns. We also believe that weight loss after bariatric surgery may significantly improve men’s health, sexual function and quality of life. In order to investigate this, we are asking men who are planning to have bariatric surgery to complete a set of surveys before their surgery and again 1-year after their surgery.
