Gastric Sleeve To Gastric Bypass Surgery in Detail

Gastric sleeve surgery is a popular and effective weight loss tool, but it’s not the right procedure for everyone. 

If you’ve had gastric sleeve surgery but find that it’s not as effective as you’d hoped or is causing you discomfort, there is the option of converting it to a gastric bypass. This procedure changes the way that food reaches your stomach as well as restricting how much you’re able to eat at once. 

  • Typically results in greater weight loss than gastric sleeve surgery 
  • Can resolve sleeve-related complications such as stenosis or acid reflux 
  • Losing excess weight can help to resolve obesity-related conditions, such as type-2 diabetes and high blood pressure 
  • Reduces your stomach’s ability to produce ghrelin, a hunger inducing hormone 
  • Infection 
  • Bleeding 
  • Blood clots 
  • Nutritional deficiency 
  • Dumping syndrome (when food moves too quickly from the stomach, leading to nausea, vomiting or diarrhoea)

Conversion from gastric sleeve to gastric bypass typically begins with your surgeon assessing the gastric sleeve to check its condition and the overall health of your gastrointestinal tract. 

If all is in order, they will then perform the gastric bypass surgery by creating a smaller stomach pouch and re-routing the small intestine to connect with both sections of the stomach. 

You’ll be under general anaesthetic for the procedure, so you’ll be asleep throughout the whole process. 

You might decide to convert your gastric sleeve to gastric bypass if: 

  • Your weight loss after gastric sleeve surgery wasn’t as much as you’d hoped, or you’ve regained weight 
  • You’re experiencing complications from your gastric sleeve, such as severe acid reflux 
  • You have comorbid health conditions that might improve with gastric bypass surgery 

After your procedure, you’ll spend one night with us before returning home to recover. 

You should be prepared to take around 1 week off work, although this depends on how physical your job is. You’ll feel slightly uncomfortable and possibly nauseous for the first few days, but this will dissipate as your body gets used to the changes in your stomach. 

We’ll give you specific aftercare instructions that you’ll need to follow in order to get your weight loss journey off to the right start. It will involve a strict post-surgery diet that you should follow for the first 4 weeks.
