What is a Roux-en-Y Gastric Bypass?
A Roux-en-Y Gastric Bypass is a weight loss surgery aimed at reducing the risks of weight-related conditions. The way it works is by creating a structure that drastically reduces the space inside your stomach, leaving you feeling full for longer. This involves creating a small upper pouch of the stomach which is directly connected to the intestines. This is a permanent procedure, and you will need to make the appropriate lifestyle changes in response to it.
Your surgery will last around 1 – 2 hours, and you should expect to stay for one night in our clinic. You should also plan to have 7 – 10 days off work, and expect a full recovery between 6 – 8 weeks.
The average weight loss experienced by patients who have a gastric bypass is 70% of their excess weight.
Do You Qualify for a Roux-en-Y Bypass?
If you have struggled with losing weight in the past, the Roux-en-Y Bypass may be a good option for you in order to reduce the risks associated with being overweight. The gastric bypass is hugely successful, lending to the overall popularity of the surgery. Those looking to have a gastric bypass should have a BMI of no less than 35, but exceptions may be made if you are diabetic or are Asian.
A Brief History
The gastric bypass was initially developed in the 1960s, after two doctors observed the weight loss experienced by patients undergoing partial stomach removal for ulcers. Over several decades the technique as we know it today, the Roux-en-Y Bypass, was developed.
As with any surgeries, there are risks involved in the gastric bypass procedure. These include excessive bleeding, infection, and blood clots among others. During your initial consultation, the Bariatric Consultant will be able to talk through these risks with you, including any questions you may have about them.
What to Expect
Completed in one of our centres, the gastric bypass will be conducted under general anaesthetic, and most are performed laparoscopically. Surgery usually takes a few hours, and you will stay overnight in the clinic to ensure your recovery goes in the right direction.
Average weight loss: 70% of excess weight.
It can take several weeks to fully recover from a gastric bypass. During this time, you should expect some natural discomfort as a result of the surgery but can look to optimise your recovery by following the expert advice of our medical team. Due to rapid weight loss, it is common to experience body aches, feeling tired, and mood changes in the first six months of having the bypass.

The most widely used measurement for obesity. The BMI approximates body mass using a mathematical ratio of weight and height [(weight in kg ÷ height in meters) or (weight in pounds ÷ height in inches x 703)]. A BMI of 30 or more is regarded by most health agencies as the threshold for obesity. A BMI of 40 or more generally qualifies as morbid obesity. However, note that BMI measurements in body-builders and athletes may not be accurate determinants of obesity because the BMI does not distinguish between muscle and fat.
