Types of Weight Loss Operations Available in the UK

By Dietitian, Juliette Kellow BSc RD

Operations for obesity are not a miracle cure to help people shift a few unwanted pounds and should not be considered to be similar to cosmetic surgery. They are a last resort for people who have severe health problems due to their excessive weight.

All surgery comes with risks and these risks are even greater for people who are obese, so any procedure should be given plenty of thought and not be undertaken lightly.

Before undergoing surgery you should be properly prepared and understand both the risks and the benefits, both in the short and long term.

You should also be fully aware of what you can expect to achieve and the type of lifestyle changes you will need to follow after the operation, including changes to your diet.

The type of operation you have will help to determine how much weight you will lose. But ultimately, a big part of the success of any of the treatments will depend upon your willingness to change your eating and lifestyle habits. Don’t be fooled into thinking that having a weight loss operation means you won’t ever need to diet or exercise again.

Ultimately, for most people, surgery means they will be on a life-long restricted eating plan that allows only small amounts of food.

Bottom line: large meals, loads of snacks and lots of fatty and sugary foods will continue to be off the menu.

There are several operations for weight loss to choose from and obese people who are suitable for surgery should discuss the risks and benefits of each with a health professional.

Some weight loss operations reduce the size of the stomach so that only small amounts of food can be eaten; others bypass part of the small intestine so that the body absorbs fewer calories from food; and others combine the two.

Types of Weight Loss Operations available in the UK

Gastric Band

A band fitted around the top of the stomach which severely restricts the amount of food you can eat.

Gastric Bypass

A line of staples separates the top part of the stomach to create a pouch which means food bypasses most of the stomach and small intestine.

Stomach Stapling (Vertical banded gastroplasty)

An obsolete weight loss operation replaced by the gastric band.

Sleeve Gastrectomy

An operation for weight loss which reduces the size of the stomach.

Bilopancreatic Diversion

This operation removes most of the stomach and attaches a small pouch left to the final part of the small intestine.

Intragastric Balloon

A deflated silicone balloon is placed into the stomach and filled with liquid to create a feeling of fullness.

Implantable Gastric Stimulator

This operation involves implanting electrodes into the stomach which stimulates the stomach to send messages to the brain to induce feelings of fullness.
