Conditions & treatments covered

At The Wellington Hospital we provide specialist laparoscopic surgery that can be tailored to provide the most suitable and appropriate treatment for you.

Gastric Banding

The lap band or laparoscopic gastric band simply works by reducing the amount of food you eat.

Gastric banding involves placing an adjustable band made up of a silicone ring and a fluid reservoir around the top of the stomach. By placing the band around the top section of your stomach a small egg sized stomach "pouch" is created, which restricts the food that can pass through the bigger part of the stomach. If the "pouch" is full and stretched, you will feel full after eating a much smaller quantity of food and won't want to eat anymore, should you try to eat more the band will cause you to be sick.

The size of the opening from the pouch determines how quickly food leaves your stomach and is adjusted by adding or removing fluid to/from the band reservoir. A thin tube connects the band to a 'port' that has been placed under the skin of your chest or below your ribs. To be effective, the band has to be tightened after 6 weeks under radiological supervision. It may have to be tightened or loosened later if required.

The band is positioned using keyhole surgery which means very minimal scarring following the operation and recovery time is much quicker.

This banding technique has been successfully used and developed since the 1980s.



A strict diet will need to be followed together with some lifestyle changes in order to get the best results from this operation. Once the optimal setting is found your band will remain in place until your weight loss target is reached.

Expected Weight Loss using a Gastric band

On average, patients can lose between 50-65% of their excess weight in the two years after placement of a lap band. But benefits can be felt within the first few weeks of having the band fitted.


Gastric band surgery is commonly performed and generally very safe. Although rare, sometimes the band may have to be removed if it slips out of place or leaks, which can occur in about 10% of people. Other problems are gastro-oesophageal reflux (heartburn) and band related problems. The required weight loss is not achieved in about 10% of patients who have a Gastric Band fitted and in this situation your Consultant may then recommend alternatives. The exact risks are specific to every individual and the surgeon will explain how these apply to you.

The surgery is fully reversible leaving no permanent affects on your stomach.


Gastric Bypass (Roux-en-Y)

The Gastric bypass procedure is the most commonly used weight loss surgery. This operation makes the stomach smaller and the digestive system (intestines) shorter, meaning that you absorb fewer calories when you eat.

Although there are a number of variations, one of the most commonly performed bypass procedures is called the Roux-en-Y gastric bypass. A small pouch, which only holds a few ounces, is created at the top of the stomach by stapling part of the stomach together - this limits how much food you eat. Then the small intestine (which carries food from the stomach) is cut and attached to the pouch to allow the food to bypass the duodenum, shortening the intestine and meaning that you have less time to absorb the food.


After the operation

Assuming that everything goes well, (and you have had a laparoscopic procedure) you will be discharged from hospital about 2 days after your surgery. It generally takes patients between two and four weeks to recover and resume normal activities.


As with any surgery, there are risks associated with the Gastric bypass procedures, these can include: internal or external hernias, bleeding or leaking from the join between the stomach and intestine, although if you have had laparoscopic surgery the risk of external hernia complication is reduced.

Not only does Gastric bypass result in reduced absorption of calories it may also reduce the absorption of important vitamins. You will be required to take daily nutritional supplements to compensate for those less absorbed (i.e. vitamins, iron and calcium).


In patients who are obese, particularly those with diabetes, the benefits of Gastric bypass surgery can outweigh the risks. The Gastric bypass operations allows greater weight loss with patients generally losing up to two-thirds (70%) of their excess weight within two years. There will also be major improvements to a whole range of weight-associated conditions including sleep apnea, arthritis, joint pain, fatigue, shortness of breath plus most type II diabetics will be cured. There is no doubt that this surgery can be life-changing and life-saving, however, the decision to go ahead with surgery should always be discussed fully with your consultant. Further information and advice about this procedure will be made available to you at your consultations with our specialists.

Gastric Balloon 

Managing your weight is increasingly difficult with the pressures of modern society. Many of us have a weight problem and many of us find it impossible to manage our weight consistently despite the well known health dangers of being overweight.

Most people have heard of the surgical procedures now being used to restrict appetite and to bring bodyweight under control. But for many people the prospect of undergoing major surgery is not acceptable. The Wellington can offer a new and increasingly popular non-surgical alternative - the Intragastric Balloon Programme.

Our specialist endoscopy teams introduce a soft silicon balloon through the mouth and into the stomach and fill it with sterile saline solution. The procedure, carried out by a senior consultant, takes a matter of minutes and is assisted by a local anaesthetic to aid the passage of the balloon.

The balloon reduces the appetite by reducing the space for food and consequently leads to planned and consistent weight loss. During the time the balloon is in the patient's stomach, a course of medication may be needed to reduce the acid content in the stomach to preserve the balloon while its presence helps weight loss.

Our senior consultants work closely with our dieticians to help patients adjust their diet appropriately and to monitor the weight loss over a period of six months. After six months the balloon is removed and our consultants and dieticians review the patient's progress and discuss follow-up dietary and lifestyle regimes or other follow-up treatments.

This new method is internationally recognised as providing a successful non surgical method of bringing body weight under control and we have a full information pack explaining the expected results and all aspects of the treatment for those who would like to consider this option.
