Gastric Band Surgery | Rivers Hospital, Hertfordshire

Gastric Band 


Gastric band or gastric banding is one of the least invasive weight loss surgeries available for overweight and obese people. It reduces hunger in results to you not needing to east as much. With a decrease in calories a gastric band helps you to lose aproximatey 50% of your excess weight if you retain good eating habits whilst improving your overall health.

What is a gastric band?

A gastric band is an adjustable and inflatable silicone band that is placed around the top of your stomach to create an upper and lower pouch. 

A small upper pouch restricts the amount of food you can eat. It works by putting pressure on hunger sensors in order to feel less hungry. This means that you will still be able to eat but you will not need so much. 

The gastric band also controls the rate at which food empties from your upper pouch into your lower stomach. It makes you feel fuller sooner and for longer on less food.

What does a gastric band involve?

 A gastric band is a commonly performed minimally invasive, reversible and adjustable weight loss or bariatric surgery that reduces the volume of food that you need to eat. 

Gastric band surgery is a quick procedure typically taking an hour, performed using laparoscopic (keyhole) surgery under general anaesthetic.

Your weight loss surgeon makes several small cuts to your stomach and inserts a long thin telescope with a tiny light and camera at one end, called a laparoscope, to see inside.

The gastric band is placed around the top part of your stomach to create a small upper pouch. The band is connected to an injection port just under your skin with fine tubing.


After your operation, your gastric band is inflated with sterile fluid via the injection port. It can be adjusted by adding more sterile fluid to inflate it or removing some to deflate it. This adjustment controls the pressure on your hunger sensor. 

Recovery after Gastric Band

Recovery after gastric band can vary from person to person.

You will stay in hospital overnight after your gastric band surgery, then usually you will go home the next day.

In the first few weeks you must follow a liquid-only diet and gradually reintroduce soft foods and then solid foods. This will take up to six weeks.

You should be able to return to work after one to two weeks depending on the extent of your surgery and your job type.

You can expect to need band adjustment appointments as it often takes several adjustments to find the right level of restriction.

You will be given advice about your gastric band diet from your surgeon or dietician together with exercise recommendations for a healthier lifestyle.

It’s important that you are committed to keeping to your new diet and way of life to help you reach your weight loss goals. People who have gastric band surgery on average lose over half of their excess body weight provided they stick to their new diet and exercise plan.

Is a gastric band right for me?

You will have tried without success to lose weight in other ways such as healthy eating, exercise and taking relevant medicines, for at least six months, before considering a gastric band.

There are pros and cons to all weight loss procedures. You should discuss all of your weight loss options with your surgeon when deciding if a gastric band is the right choice for you.

The benefits of a gastric band are that it is the least invasive weight loss surgery with a shorter hospital stay, faster recovery time, and smaller scars. It is also a reversible procedure so if you decide it’s not for you, you can simply have the band deflated and removed.

Your gastric band can be individually adjusted to control the rate of food passage from your upper to your lower pouch to help your weight loss.

Weight loss may be more gradual with a gastric band but, if you are committed to a new healthier lifestyle and gastric band diet, you can achieve substantial long-term weight loss.

As you lose weight you should see improvements in obesity-related problems such as type 2 diabetes, high cholesterol, sleep apnoea, high blood pressure and asthma.

Unlike with some weight loss surgeries a gastric band doesn’t interfere with your food absorption so you shouldn’t experience vitamin deficiencies and you are less likely to suffer from symptoms of dumping syndrome.

You will also need to check your eligibility for a gastric band. You may be eligible if: your BMI score is over 40, or over 35 if you have other medical conditions such as type 2 diabetes or high blood pressure that may be improved by losing weight. You will need to be fit enough to have a general anaesthetic and surgery. You must also be committed to long-term lifestyle and diet changes for weight loss and maintenance.
