A gastric bypass is a permanent weight loss surgery and is essentially irreversible. There is a revision procedure but there is a high risk of complications attached and this is only really carried out if absolutely necessary.
If you are unsure about permanent weight loss surgery then there are non-permanent alternatives available. This includes a gastric band, where a band is placed around the top of the stomach, and can be tightened, loosened or removed where necessary, and a non-surgical gastric balloon. In this procedure a balloon is placed in the stomach and filled with saline fluid, meaning there is less space in the stomach for food. Our expert surgeon can talk you through the options and help choose which would be the best to meet your needs.
