Stomach Stapling & Gastric BypassWeight loss surgery can involve anything from gastrointestinal surgery to stomach stapling (gastroplasty) to gastric bypasses (jejunoileal bypass). Other weight loss surgery options are stomach wrapping, jejunocolic bypass, truncal vagotomy and biliopancreatic diversion. These operations work on the premise that by creating a small stomach pouch, individuals will lose weight because they feel fuller. The size of the pouch prevents individuals from over eating as individuals feel ill when they eat more then what the pouch can accommodate.Lap-Band Adjustable Gastric Banding SystemThis is a more modern and flexible procedure, which involves inserting a ‘band’. The operation involves surgically inserting a ‘lap band’ in the stomach, which is designed to limit food consumption and give the person a sense of fullness. The band is implanted through elective keyhole surgery (laparoscopic) and is tailored made to suit the individual. Saline is injected into the band to form a smaller gastric band which limits calorie intake. The band is highly versatile and can be adjusted (tightened or loosened) according to the dietary needs of the individual. This type of weight loss surgery claims to be more effective and less invasive than current weight loss procedures. A three year study on the lap band revealed that after this type of weight loss surgery, sixty six per cent of the patients involved lost at least a quarter of their weight. However there were some patients who experienced at least one if not more of the following side effects: vomiting, heartburn, band slippage, and abdominal pain.LiposuctionLiposuction appears to be the ultimate way to go: so much fat can be removed from exactly the areas we want it to, without the stress of food restriction.If something sounds too good to be true - it usually is! So is liposuction. Most methods of liposuction involve injection of anesthetics and epinephrin into the fat tissue. They also involve general anaethetic and large amounts of blood loss. Liposuction is a very sophisticated technique and can easily go very wrong or produce an unwanted very unappealing result. ConsiderationsWeight loss surgery is a very sensitive issue. An obese person is classified as a person who weights more than 50 kg or double their ideal weight. Individuals who are obese usually have associated health problems such as diabetes, hypertension and sleep apnea. Weight loss surgery often involves a second or third operation to fix problems which arise after the initial surgery. This is dangerous and the surgery is very complicated. When weight loss surgery goes wrong, it can be life threatening.The health risks to weight loss surgery are mainly pulmonary embolism and thrombosis. Obese people should exhaust all options to lose weight before resorting to weight loss surgery, which is the last option. Non-surgical treatments are much more effective than weight loss surgery because weight loss surgery does not fix the cause of the problem and the weight will come back unles the cause is addressed. |
