Obesity is classified as a body mass index (BMI) above 30 kg/m2 by the World Health Organization. Both overweight (BMI \> 25 kg/m2) and obesity (BMI \>30 kg/m2) have increased worldwide during the last decades: 1.46 billion of the adult population were estimated to be overweight in 2008, particularly 205 million men and 297 millions of women were estimated to be obese. Obesity is associated with lower quality of life and is linked to serious comorbidities such as type 2 diabetes mellitus, hypertension, cardiovascular diseases and several cancers. Furthermore, obesity is significantly linked to a higher mortality risk compared to normal weight individuals. Obesity is also significantly increasing in patients with IBD. Obesity enhances the inflammatory activity in IBD, leads to longer hospitalization, and increases the possibility to develop extra intestinal manifestations. Also, the frequency of having extended systemic steroid treatment and use of antibiotics seems greater in IBD patients with obesity. Hence, treatment and prevention of obesity, especially in IBD patients, should have high priority.
