Procedure Information
Gastric Sleeve Surgery60-70% of excess weight▼
Gastric sleeve surgery involves removing a large part of your stomach to decrease the amount of food you're able to consume. The procedure enables you to gradually lose weight as your meal sizes are restricted and your calorie intake is reduced. After surgery, your body will produce lower levels of the hunger hormone Ghrelin.
Gastric Bypass Surgery70-80% of excess weight within the first year▼
Also known as the Roux-en-Y, the procedure involves creating a pouch out of your stomach and joining it to your small bowel to circumvent part of the gut, restricting the amount of food you can eat and the number of calories you can absorb. It also alters your gut hormone levels, helping you to feel full earlier.
Gastric Band SurgeryOn average, patients lose 40 per cent of their excess weight▼
During a Gastric band Surgery, an adjustable silicone band is wrapped around the stomach forming a small pouch. This results in less food needing to be consumed before you feel satisfied and full, as the pouch takes less food to fill up compared with your stomach.
