What happens during gastric bypass?
- A gastric bypass is performed under general anaesthetic and usually takes between two and four hours
- Your surgeon will usually use laparoscopic (keyhole) surgery
- They will make several small cuts on your abdomen
- Your surgeon will place surgical instruments along with a telescope inside your abdomen to perform the operation
- Your surgeon will create a tunnel behind your stomach
- They will pass a stapling device through the tunnel and then staple your stomach to create a smaller stomach pouch
- They will divide your small bowel below your stomach and bring up the lower end and attach it to your new stomach pouch
- The contents of your new stomach pouch will now bypass the rest of your stomach and the first part of your small bowel.
Going home after gastric bypass
- You should be able to go home the day after your procedure
- Your stomach may be sore and you may experience nausea or vomiting
- These symptoms should ease quickly
- You will start with a liquid-only diet, progressing to soft food and then to solid food
- Due to nutritional deficiencies created by gastric bypass you may need dietary supplements for the rest of your life
- Some patients experience “dumping syndrome” if they eat the wrong foods; resulting in nausea, vomiting and diarrhoea
- You should be able to return to work after two to four weeks depending on the extent of surgery and your type of work
- Many patients experience rapid weight loss in the first 6-9 months following gastric bypass
- It is important that you maintain any diet or exercise programme prescribed in order to continue this progress.
