How the surgery is done
After you’ve been put to sleep with general anaesthetic, your surgeon accesses your stomach via 5 small incisions. They then reduce the size of your stomach by stapling along the length of it to form a long tube that looks like a banana. The rest of your stomach is then removed.
The surgery generally takes 1 – 2 hours. Average time off work is 2 – 4 weeks.
How it works
- Your new stomach pouch holds much less food than a normal stomach. This helps to reduce the amount of food (and calories) you can consume.
- The hormone that makes you feel hungry is produced in your stomach so reducing the size of your stomach reduces hunger pangs while increasing feelings of fullness.
- the complication rate is lower than the Roux-en-Y gastric bypass
- short-term studies show that gastric sleeve surgery is as effective as the Roux-en-Y gastric bypass in terms of weight loss and improvement in diabetes
- you can expect to lose over 50% of excess weight after 3 – 5 years and over 50% of people manage to keep the weight off
- you won't have a foreign objects in your body (unlike the adjustable gastric band), and no bypass or re-routing of the food stream (unlike Roux-en-Y gastric bypass)
- you’ll have a relatively short hospital stay of around 2 days
- it changes your gut hormones, suppressing hunger, reducing appetite and making you feel full.
- the procedure isn’t reversible
- the complication rate is higher than for the adjustable gastric band
- it has the potential to cause long-term vitamin deficiencies
- early complications include bleeding (1% – 6%) and leakage along the staple line (up to 5%)
- later complications can include gastric reflux (47%) nutrient deficiency (up to 23%) stricture (3%) and abscess (less than 1%).
