Gastric Bypass

A gastric bypass is a weight loss surgery procedure that uses both restrictive and malabsorptive elements. The result is you simply cannot eat as much and thus you absorb fewer calories.

What happens during gastric bypass?

Gastric Bypass SurgeryA gastric bypass is performed underĀ general anaestheticĀ and usually takes between two and four hours.

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

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.

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.
