Gastric Sleeve Surgery

We’re the UK’s most trusted weight loss & cosmetic surgery provider

Say hello to a new you.

If you have been unable to lose weight through diet and exercise alone, gastric sleeve surgery could help you achieve your weight loss goals. Also known as sleeve gastrectomy, gastric sleeve surgery may be suitable if you have a BMI of over 30, especially  if you have Type 2 diabetes, or if you suffer from another condition associated with obesity.  

Gastric sleeve surgery can result in considerable weight loss, giving you a healthier, more fulfilling lifestyle. Less invasive than a gastric bypass but more complex than a gastric band, gastric sleeve patients lose on average 55-60% of excess weight after three years, according to the 2014 National Bariatric Surgery Registry Report.

The procedure involves reducing the size and capacity of the stomach by around 75%, which includes removing the upper part of the stomach where ghrelin (the hormone that stimulates hunger) is produced. This helps to reduce appetite and portion size, significantly assisting your weight loss efforts.

If you are thinking about gastric sleeve surgery, contact us today to arrange a consultation with one of our experts, who will help you decide on the best way to begin the next chapter in your weight loss journey.

What is gastric sleeve surgery, and how does it differ from a band or bypass?

Although the purpose of all three weight loss surgery procedures we offer is to reduce appetite and portion size to ultimately help with weight loss, there are some key difference between these procedures.

The sleeve gastrectomy procedure is normally done as key hole surgery and involves vertical removal of most of your stomach. This then helps to control food intake. Similarly, to bypass surgery, gastric sleeve surgery is irreversible. The vertical sleeve gastrectomy is sometimes recommended over other forms of bariatric surgery if a medical condition would rule out the other forms of surgery.

Gastric sleeve surgery is also a little less invasive than gastric bypass, during which the top of the stomach is stapled, creating a small pouch that is then connected to the small intestine. Because the pouch is smaller, and the rest of the stomach is bypassed, you will feel full after eating less. Hormones that stimulate satisfaction increase and hormones that stimulate hunger decrease.

Finally, gastric band is less invasive than gastric sleeve or bypass surgery. A band is placed around the top of the stomach, which stimulates nerve endings tricking the brain into thinking the stomach is full.  This helps you to feel satisfied on smaller portions.

Whether you are considering sleeve, bypass or band surgery, we always advise to book a free consultation with one of our Patient Advisor first to discuss your weight loss surgery options.

The main purpose of gastric sleeve, band, and gastric bypass surgeries is reduce appetite and portion size. The way this is done depends on the kind of surgery:

Gastric sleeve

How does it work?

The upper part of the stomach is removed, reducing the capacity of the stomach by around 75%, along with the area of the stomach where ghrelin (the chemical that stimulates appetite) is produced. Your portion size and appetite are therefore reduced.

Because the pouch is smaller and the rest of your stomach is bypassed, you will feel full after eating less, your overall appetite will reduce and you may absorb fewer calories from your food.

Is it reversible? 

No

Gastric band

How does it work?

Less invasive than gastric sleeve surgery. A band is placed around the top of the stomach, which Stimulates nerve endings, tricking your brain into thinking the stomach is full.  You feel more satisfied on smaller portions of food.

When you’re deciding whether to have surgery, it’s reassuring to have all the facts. You’ll be able to ask any questions at your consultation, but here are some that our patients most frequently ask.

Gastric sleeve FAQs

It’s a weight loss procedure where most of the stomach is removed, reducing its capacity by up to 75%, along with the removal of the area where the hormone that stimulates appetite is produced. As a result, your portion size and appetite are therefore reduced. It is important to make lifestyle changes too in terms of healthy eating and regular activity to achieve the best possible results.

As 75% of your stomach is removed, naturally your appetite and the portion sizes you can manage will reduce. One of our dedicated and expert dietitians who will be looking after you will advise you on food and liquids intake throughout the length of your aftercare cover, depending on the package that you choose.

All surgery comes with the risks of complications, which will be explained to you fully in your consultation, so you are fully aware of what is involved and can make an informed decision about having gastric sleeve surgery.

Some people may experience dumping syndrome after a gastric sleeve procedure. This is the name given to a range of symptoms experienced after consuming food or fluid containing a lot of carbohydrates (especially sugar). It occurs because the stomach empties more quickly after gastric sleeve surgery compared with before.

You will be fully supported by one of our specialist dietitians to ensure that any potential risks of malnutrition and dumping syndrome are minimal, and you will also have the opportunity to purchase vitamin and mineral supplements to ensure that you are getting all the nutrients you need.

Gastric sleeve surgery can completely overhaul your health and overall quality of life and most people are successful in accomplishing significant weight loss – as much as 55-60% after three years.

Losing significant amount of weight can lead to a happier, more fulfilling life, ability to enjoy higher energy levels and more freedom in the things you can do. It can also help treat and reduce the impact of illnesses and some medical conditions associated with obesity.

Gastric sleeve surgery a is permanent decision and an irreversible surgery, so you cannot change your mind once you have had the procedure as it involves the removal of part of your stomach. As with any surgery, gastric sleeve surgery carries some possible complications which will be discussed with you in details prior to the surgery. 

The gastric sleeve is more invasive than a gastric band, but not such a major operation as a gastric bypass. It may therefore suit patients for whom the bypass is inadvisable due to health complications. Usually patients most suitable to have gastric sleeve surgery are those with a BMI of 40kg/m2 or over, although if your BMI is between 30kg/m2 and 40kg/m2, you may be considered, especially if you have obesity-related conditions such as Type 2 diabetes and even more so if you are from an Asian background (source: National Institute for Health and Care Excellence (NICE) guideline 189, 2014). However, surgery is dependent on a bariatric surgeon’s opinion and your individual circumstances. All our weight-loss surgery patients have an in-depth consultation prior to surgery to discuss the most suitable procedure for them.

You will normally stay in hospital for 2-3 nights after your surgery.

The sleeve works to reduce portion sizes, not specific food types. Compared to the bypass, there are fewer restrictions on the types of food that patients can consume. However, some patients may struggle with certain textures of food such as bread or red meat.

We advise you avoid alcohol for the first 4 weeks and following this, be mindful that your tolerance is likely to reduce. After your surgery, it is likely you will absorb alcohol into your bloodstream more quickly than before the operation.

Dumping syndrome or rapid gastric emptying is relatively common following bariatric surgery procedures that bypass the majority of the stomach. It describes the symptoms that occur when food moves too quickly through the stomach and “dumped” into the small intestine. However, only 1% of patients report their symptoms difficult to manage, and often occurs less as time passes.

The overall recovery time after a gastric sleeve procedure will vary based on you and your individual circumstances. Many people feel comfortable walking a day or two after the surgery and can return to work within a few weeks, but it is best to always follow the advice of your expert weight loss surgeon.

According to the NHS, more people tend to achieve significant weight loss with a gastric bypass or sleeve gastrectomy than with a gastric band. Most people are successful in accomplishing significant weight loss – as much as 55-60% after three years but this will vary from person to person and the amount of effort that you put into changing your lifestyle and eating habits.

The cost of gastric sleeve surgery may vary, depending on a range of factors. Use our price check to work out how much your surgery could cost. You can choose to pay for your treatment in full or spread the cost out over 24, 36, 48 or 60 months using our finance options.

For example, if your gastric sleeve procedure costs £9,145 you could pay a £500 deposit on a loan plan at 12.9% APR and pay 60 monthly instalments at £193.18pcm this would mean you’d pay £12,090.80 in total.

Our 0% finance options allow to spread the costs surgery over a 6, 10 or 12-month period completely interest free.

On the day of your surgery, your medical team will make your experience as comfortable as possible and you’ll meet your surgeon again before the procedure. The gastric sleeve procedure is usually carried out as keyhole surgery. It involves vertical removal of up to 75% of the stomach area to leave a thin sleeve. The stomach continues to function as normal, but the smaller sizerestricts the amount you can eat and makes you feel full after smaller meals. It also aims to drop appetite hormone levels to reduce your appetite. Less stomach acid is produced, which can affect the absorption of some vitamins and minerals and so supplements are required for life. Gastric sleeve surgery is non-reversible.
