Gastric Sleeve Cost

Getting gastric sleeve surgery privately in the UK will cost you from £7,995 up to £15,000.

Most clinics provide finance packages to help you spread the cost of your surgery. These typically involve an initial deposit followed by small monthly payments over a pre-agreed time period.

Gastric sleeve surgery is available on the NHS for free, but the strict eligibility criteria means you may not qualify for the procedure.

How Much Does Gastric Sleeve Surgery Cost?

You should expect to pay anywhere between £7,995 and £15,000 for gastric sleeve surgery at a private clinic in the UK, making it one of the most expensive types of weight loss procedures. The table below compares the price of gastric sleeve surgery against the other types of gastric surgery:

Procedure Description Price Range (GBP)

The price of gastric sleeve surgery varies depending on your general health and the clinic at which you undergo the procedure. Since prices are determined on a case-by-case basis, the actual price you will pay may differ considerably from the advertised price. We do not recommend that you opt for the cheapest price you can find however, as this is often a reflection of the poorer quality of the procedure. Clinic Compare has researched the cost of gastric sleeve surgery at some of the leading private clinics in the UK to give you an estimate of how much you could pay for the procedure:

Clinic Starting Price
The Hospital Group £9,950
Spire St Anthony’s Hospital £10,300
Ramsay Health Care UK £7,995
Healthier Weight £9,990
The London Clinic £9,885

When researching costs, it is important that you find out what is included in the advertised price. Some clinics may charge extra for services such as aftercare and follow-up appointments, meaning you will end up paying more than you initially anticipated. You should make sure you know about these additional costs so that you can factor them into your budget.

Gastric Sleeve Surgery Financing

Many clinics offer finance packages to allow you to spread the cost of your procedure, with most offering a 0% APR option on your monthly payments which means that you pay back only the cost of the procedure. Some clinics do however charge interest in order for you to spread the cost. An example of the difference interest makes to your overall payment is shown below:

  • £10,000 at 0% APR over 2 years = £416.67 per month - Total Repaid = £10,000
  • £10,000 at 7% APR over 2 years = £475 per month - Total Repaid = £11,400
  • £10,000 at 7% APR over 4 years = £266.67 per month - Total Repaid = £12,800

You should always discuss in detail the finance packages available from your clinic, the total amount repayable and what is included in the price, to make sure you are fully aware of all the cost implications. The table below shows you the finance packages available at some of the top weight loss clinics in the UK:

Clinic Finance
The Hospital Group
  • £500 deposit
  • 0% APR for up to 12 months
  • 9.9% APR for over 12 months
Spire St Anthony’s Hospital

  • No in-house finance
  • Recommend Zebra Health Finance
Healthier Weight
  • £500 deposit

Not everyone will be eligible to get gastric sleeve surgery on finance, since many clinics have a strict acceptance criteria that you must meet in order to qualify for financial support. The criteria typically includes that you:

  • Are a UK resident and have lived at a registered address for at least 3 years
  • Have been in full time employment for at least 1 year
  • Have a bank account from which you can set up direct debits

If you have defaulted on any previous payments, have had a bankruptcy notice or have an IVA in your credit history, you may find it difficult to be accepted into any financial agreement.

Can I Get A Gastric Sleeve On The NHS?

Gastric sleeve surgery, as well as other types of gastric surgery, are not usually performed on the NHS. In extreme cases however, if the patient has not responded to diet or exercise, and every other form of non-surgical weight loss has been explored, then it may be possible to have a gastric sleeve operation free on the NHS.

If the patient can prove that they have tried dieting and exercising, and have a Body Mass Index (BMI) of more than 40, or a BMI of 35 or above coupled with a serious obesity-related health condition that stands a good chance of been remedied by surgery such as hypertension or type II diabetes, then they have a chance of being accepted for surgery on the NHS.

The first step towards finding out if you are eligible for a gastric sleeve on the NHS is to make an appointment to speak to your GP. To get an idea of whether you are entitled to free surgery, you should consult the weight loss section of the NHS website.

How Is Gastric Sleeve Surgery Performed?

gastric sleeve procedure

A gastric sleeve is a surgical procedure designed to limit your food intake and thus aid in losing weight. During the procedure, a portion of your stomach is removed, reducing the size available to take in food by up to 75%.

Gastric sleeve surgery is carried out under general anaesthetic, and takes roughly one to one and a half hours to complete. During the operation, a large incision will be made, or your surgeon may make small incisions and insert a laparoscopic camera to see inside. They will then remove more than half the stomach, creating a banana-sized pouch or “sleeve” instead.

This reduction in size means you feel full sooner and eat less, both of which help with weight loss. The surgeon will close the new sleeve with sutures before closing the incision with sutures. As a substantial part of the stomach has been removed, the procedure is permanent and cannot be reversed.

In preparation for your surgery, you will have to follow a full liquid diet for 2 weeks before undergoing your procedure. This is beneficial for numerous reasons, as it:

  • Gets you used to limiting your food intake ready for your new postoperative diet.
  • Reduces the size of your liver, making the surgery easier and quicker.

The night before the surgery, you must also fast to avoid potentially serious complications. This means it is essential that you do not eat, drink or even chew gum in order to prevent your surgery being cancelled and rescheduled.

Recovery From Gastric Sleeve Surgery

Following the procedure, you may be in hospital for a couple of days before being discharged to recover at home. It is normal for patients to experience pain in the abdomen following surgery, and your doctor may provide prescription painkillers to help with this. The area around the incision may also feel sore and tender, and it is recommended to take things slow during the weeks following your surgery. You should be able to return to work and resume normal activities within 4 to 6 weeks of your operation.

You will have to follow a strict diet plan to slowly reintroduce food into your diet. For the first two to three days you will only be allowed to consume liquids, beginning with small sips of water. For the following 2-4 weeks you can then progress onto thin soups and pureed foods taken in 4-6 small portions throughout the day. Once these meals are tolerated well enough, you can begin eating mashed foods along with plenty of water, before moving onto more solid foods and a healthy balanced diets from 6 weeks onwards.

In addition you may also have to take vitamin supplements as a result of the procedure, either in tablet or injection form. This will help to prevent the development of conditions such as anaemia.

What Are The Risks?

Watch Mr Chris Sutton, Consultant Specialist Bariatric Surgeon at Tonic Weight Loss Surgery Ltd, describe the side affects associated with gastric sleeve surgery:


Video Transcript

"Side effects following a sleeve gastrectomy very low indeed. As long as there wasn’t a problem at the initial operation such as a bleed or a leak, a sleeve is probably one of the easiest operations to live with. Patients can eat almost any food but obviously in a smaller portion. They often don’t feel hungry following the sleeve because the parts of the stomach that’s removed removes what’s called the Gherlin Secreting Cells, the Gherlins are hormones that drive appetite and it’s made in the part of the stomach that is removed following a sleeve gastrectomy."

Mr Chris Sutton, Consultant Specialist Bariatric Surgeon at Tonic Weight Loss Surgery Ltd


Like with any operation, there are a number of general risks that result from gastric sleeve surgery. These include:

  • Nausea and vomiting
  • Blood clots
  • Infection
  • Internal bleeding
  • Reactions to the anaesthetic

You may also experience some more specific risks as a direct result of the surgery, including:

  • Gallstones
  • Food intolerance
  • Acid reflux
  • Excess skin
  • Leakage from where the stomach was closed, which may mean a further procedure to repair the join and stop the leakage (peritonitis)

Some patients also experience 'dumping syndrome', which occurs when food passes through the gastric sleeve into the small intestine too quickly. Symptoms of dumping syndrome include diarrhoea, nausea and vomiting, and abdominal pain. Avoiding consuming fatty and sugary food, and introducing high-fibre foods into your diet can help prevent dumping syndrome from occurring.

Your surgeon should discuss all of these potential side effects with you before your procedure to make sure you are fully aware.

Considering Surgery?

Weight loss surgery does not give immediate results and only works if you change to a healthier lifestyle. It should only be viewed as a last resort and should not be attempted before trying other methods of weight loss, such as changing diet and increasing exercise.

If you do not want to undergo gastric sleeve surgery, there are numerous other weight loss surgeries available today including a gastric balloon, bypass or band.
