About weight loss surgery

  • Obesity is now a world health concern as the numbers suffering from the condition have increased as much as five hundred per cent in the last seventy years.  

    Excess weight can bring along with it potentially very serious physical and mental health conditions including;
    Loss of confidence
  • Depression 
  • Chronic musculoskeletal problems
  • Osteoarthritis 
  • Cancer 
  • Sleep apnoea  
  • Gallbladder disease 
  • Diabetes
  • Hypertension
  • Heart disease
  • Stroke

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.

At the initial consultation, your consultant will listen to your concerns and will take a full medical history. Surgical options will be discussed as well as any limitations.

Types of Weight loss surgery

Need to know

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.

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.
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.
