Gastric bypass surgery

Laparoscopic biliary gastric bypass (Roux-en-Y)

Our experienced surgeons specialise in minimally invasive procedures to aid weight loss, including gastric bypass

About

Excess weight is known to increase the risk of serious conditions including diabetes, hypertension and heart disease. If your body mass index (BMI) is over 35, gastric bypass surgery can help you achieve long-term weight loss, improving your overall health and allowing you to participate more fully in the activities you enjoy.

Need to know

  • What happens icon plus

    The gastric bypass involves stapling the stomach to produce a much smaller stomach, which will reduce from the size of the stomach from that of a Galia melon to the size of an egg. The second part of the operation involves bypassing the digestive secretions that are normally involved in absorption of foods.

    A loop of the small bowel is bought up to the new small stomach and connected to this. This new configuration bypasses the digestive secretions for half of the bowel length. Eventually food and secretions will remix half way down the bowel.

    The procedure is under general anaesthetic and takes on average one and a half hours
  • How to prepare icon plus

    Your consultant will explain the procedure to you and answer any questions you may have. They'll let you know how to prepare, including any special dietary requirements in the days leading up to your procedure.

    Because you'll be having general anaesthetic, they'll also let you know how long you should 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

    The morning after surgery you should be able to walk around your private room, use the bathroom and shower. You should be able to sit comfortably and drink tea, smoothies or milk. Your pain should be well controlled with soluble painkillers.

    Some patients will be keen to go home the day after surgery but most will prefer to stay and relax in the hospital and return home after the second night.

    You will need to take 1 or 2 weeks off work.
