Weight loss surgery

Laparoscopic bariatric operations

​We specialise in minimally invasive procedures to aid weight loss, including gastric banding and gastric bypass surgery


Excess weight is known to increase the risk of serious conditions including diabetes, hypertension and heart disease. Not only can weight loss surgery reduce these risks, it can also improve chronic joint pain and boost energy levels, helping you participate more fully in the activities you enjoy.

Types of Weight loss surgery

Sleeve gastrectomy

Surgery to reduce the size of your stomach to a short tube shape to aid weight loss

Partial gastrectomy

Part of your stomach is removed during a partial gastrectomy, to make your stomach smaller

Gastric banding

An adjustable silicone band is placed around the top of your stomach. This restricts the amount of food that can pass through to your stomach

Gastric Bypass

The gastric bypass involves stapling the stomach to produce a much smaller stomach, which will reduce from the size of the stomach

Need to know

  • What happens icon plus

    Gastric bypass and gastric banding surgery work by making your stomach smaller — either with surgical staples or a special silicone band. Bypass surgery (Roux-en-Y) attaches your small intestine directly to this new smaller stomach. These procedures make you feel full faster, cutting down your calorie intake and making it less likely you'll overeat. Both procedures are done under general anaesthetic, meaning you'll be asleep. Often surgery can be done as a keyhole (laparoscopic) operation for faster recovery. Depending on your overall health and the amount of weight you need to lose, your consultant will recommend the best procedure for you.
  • How to prepare icon plus

    Your consultant will explain the different options available to help you reach and maintain a healthier weight. Once they've determined the best option for you, they'll explain the procedure and answer any questions you may have. They'll let you know what you need to do to prepare for surgery, including how long you'll need to avoid eating and drinking beforehand. Like all procedures, there may be some risks and side effects involved. Your consultant will explain these to you.
  • Afterwards icon plus

    You should be able to go home within two days, depending on the type of surgery you've had. Your consultant will let you know what to expect and tell you when you can get back to your normal activities. They'll also explain your dietary restrictions, including if and for how long you should stick to a liquid diet. If you've had gastric banding, you may need to return in a few weeks to have your band tightened. On average, people who undergo weight loss surgery can expect to lose over half of their body weight. Regular exercise and healthy eating habits will help to improve your overall health and lifestyle.
