Preparing for gastric bypass surgery at Spire Cardiff

Getting here

Spire Cardiff Hospital is located a short distance from Junction 30 of the M4 and is well signposted. We have free on-site parking for you and your visitors.

Your consultations

Your initial appointments will take place in one of our 21 consultation rooms. During your consultations, we’ll:

  • Ask about your medical history
  • Explain about the different surgical methods – your consultant may recommend gastric sleeve surgery first
  • They’ll explain what’s included in your treatment price
  • Explain about your aftercare, the diet and exercise plan you’ll need to follow and how the operation will affect your lifestyle in the long term
  • Discuss risks and complications

The consultations give you an opportunity to ask any questions you may have. Your consultant will explain that there’s no pressure to make any decisions during the appointment. Once you and your consultant have decided to go ahead with a gastric bypass, you’ll also be assessed by a physician, a dietitian and bariatric nurse. You'll also need to have a pre-operative assessment which may include:

  • Blood tests
  • An electrocardiogram (ECG)

Gastric bypass surgery: your procedure

When you come in for your operation, you’ll be with us for approximately three days. You’ll stay in one of our large, bright, private en-suite rooms. All our rooms have the comforts and conveniences you’d expect to find at home, including:

  • TV
  • Window
  • Armchair
  • En-suite

Here’s what will happen on the day of your gastric bypass:

  • You’ll meet your surgical team and anaesthetist
  • Your anaesthetist will administer the general anaesthetic, which will send you to sleep for the operation
  • Once it’s taken effect, your surgeon will carry out the surgery to reduce the size of your stomach and connect it to the lower part of your small intestine
  • Your operation will take between one and three hours

If you’ve come with a friend or family member, they’re welcome to wait in our lounge or restaurant while you have your operation.

Your aftercare and recovery

While you’re in hospital, your nursing team will give you pain relief as and when you need it to make sure you’re comfortable.

After you leave hospital, we’ll arrange to see you for 18 months to two years after your operation so we can keep track of your progress and ensure you’re recovering and losing weight as intended.

Although everyone’s different, here’s a typical recovery guide for gastric bypass surgery:
