A gastric bypass involves diverting the digestive channel. In 2008, 3,079 such operations were performed. In 2011, this had increased to 6,989.
Until a few years ago, the gastric ring was by far the most popular gastric reduction technique. However, Bruno Dillemans of the Centre for the Study of Obesity in Bruges (West Flanders) told the papers that recent studies have shown that gastric bands are less durable than a gastric bypass.
Mr Dillemans adds that in his view the total number of gastric reductions has remained more or less stable, but more patients are opting for a gastric bypass, rather than a gastric band or a gastric ring.
Since 2007, the conditions for the repayment of all the costs of the gastric bypass operation have been relaxed. Such an operation costs around 6,000 euro.
Mr Dillemans believes that this money well-spent. "This kind of operation has been carried out in the United States for many years now and it has proved its long term value to society."
