A brief overview of your interest group (be sure to put its name in bold in the first sentence) and the scope of the article goes here.[1]
The following list of sections should serve as a loose guideline for developing the body of your article. The works cited in references 2-5 are all fake; their purpose is to serve as a formatting model for your own citations.
Introduction
Surgery as a treatment for obesity
For many obese patients, diets and lifestlye changes do not work in long term. Bariatric surgery has proved to be the only effective method in the long term treatment of obesity.
How surgery works
Bariatric surgery works by altering the anatomy of the gastrointestinal tract, thus: limiting the volume of food the stomach can hold, interfering with the absorption of calories, and by interfering with orexigenic and anorexigenic signalling between the gut, adipose tissues and the brain.
Bariatric Surgical Procedures
Restrictive Surgery
Restrictive surgery reduces the size of the stomach causing decreased hunger and an increased satiety following ingestion of smaller amounts of food. Surgical procedures include gastric banding, where an adjustable band is clipped just below the cardia of the stomach creating a small gastric pouch above(kerrigan, le roux). Other forms of restrictive surgery includes gastroplasty and sleeve gasrectomy.
Malabsorptive Surgery
Jejuno-ileal bypass, duodenojejunal bypass and biolopancreatic bypass (with or without duodenal switch)
Combination Surgery
Combination surgery combines the benefits of both restrictive and restrictive surgery. The most common bariatric procedure in the US is the Roux-en-Y Gastric Bypass (RYGP).
Duodenal switch
