  4. In 2000 the extra weight of obese passengers cost airlines $US275 million due to higher fuel costs and pressures to increase seating width
  5. In the US 23-41% of dogs are overweight and about 5.1% are obese
  6. In the USA close to 20% of children are technically obese

Weight loss surgery

  1. Approximately 500,000 bariatric operations are performed worldwide each year
  2. The most commonly performed weight loss operation performed around the world in 2015 was gastric bypass surgery.  Sleeve gastrectomy was second most commonly performed.
  3. The EndoBarrier implantable device for weight loss is utilized in South America, Australia, Europe and other countries.  However it cannot be used in the United States.
  4. The adjustable gastric band (e.g. Lap Band) was in used around the world since the early 1990s but was only approved for use in the US in 2001.
  5. The sleeve gastrectomy was used as part of an operation called duodenal switch.  However many patients were too large for duodenal switch so the first part (the sleeve) was done first to be followed by the second part when some weight had been lost.  However for many patients, the second part was not required as weight loss was excellent with the sleeve component.
