Gastric Bypass Surgery

Gastric bypass surgery is a highly effective weight loss procedure for obese people who want substantial and long lasting weight loss.

What does a gastric bypass procedure involve?

Gastric bypass surgery is often performed using keyhole (laparoscopic) surgery although sometimes open surgery is more appropriate.

The most common gastric bypass procedure is the Roux-en-Y gastric bypass. A stapler is used to divide your stomach into two parts. This creates a smaller pouch at the top that allows you to take in less food to feel full.

Your top stomach pouch is attached directly to a section of your small intestine so that your food bypasses the rest of your stomach and much of your intestine. This rerouted passage is made narrow to keep your food in the upper pouch longer and make you feel fuller longer.

How does a gastric bypass work?

A gastric bypass works by using both restriction and malabsorption. As your stomach is smaller it restricts the amount of food you can eat and as parts of your intestine are by-passed less calories are absorbed by your body from the food.

Why choose a gastric bypass procedure?

  •                     A very effective weight loss choice offering rapid weight loss.
  •                     It’s used to improve conditions related to obesity such as: diabetes,                         high blood pressure, high cholesterol, arthritis, sleep apnoea and                             heartburn.
  •                     Good long-term results.

How much weight can I lose with a gastric bypass?

Weight loss after gastric bypass surgery can vary depending on a person’s individual circumstances and commitment to making diet and lifestyle changes.

On average people see considerable and long lasting weight loss of up to 65 to 75 percent of their excess body weight within 12 to 18 months.

Things to bear in mind when considering a gastric bypass

This is a major surgical procedure. It’s more extensive and complex than other weight loss surgeries and as such can carry higher risks.

You’ll need to take multi-vitamin supplements or the rest of your life to ensure you don’t suffer from nutritional deficiencies due to the change in food absorption.

You may suffer from ‘dumping’ of your food into the intestines too quickly before it’s been properly digested. Dumping syndrome is common in gastric bypass patients although they learn to avoid these weight gaining foods that lead to dumping syndrome.

Am I eligible for a gastric bypass surgery?

To be eligible for gastric bypass surgery you must:

  •          a BMI (Body Mass Index) of 35 plus and have a medical condition like high              blood pressure and diabetes or a BMI of 40 plus
  •          be aged 18 or over
  •          be prepared to maintain a medically supervised program
  •          be fit enough to have anaesthesia and surgery.
