Obesity (Background) 

In recent decades, obesity has become a worldwide issue. Obesity has rapidly developed into a major global public health challenge. Canada is not alone in observing increases in obesity, approximately 24% of adults are obese One in four Canadian adults (estimates range from 24.3%-25.4%) are obese, according to measured height and weight data from 2007-2009. 

Obesity is an important population health concern and the causes of, and the contributing factors obesity are complex and multifaceted. Current evidence also suggests that people who are severely obese have a greater risk of premature mortality, with an increased risk of major chronic diseases as such heart disease, diabetes, depression and many types of cancers. Bariatric surgery has proven to be an effective treatment for obesity and the related metabolic complications. 

The impact of obesity in Canada has been a financial burden, with an aggregated annual cost of obesity between 1.27 to 11.08 billion dollars.
