Gastric Sleeve Surgery

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

Start your journey to a new you.

If you’ve 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.

How is the gastric sleeve surgery performed?

The gastric sleeve 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.

Gastric bypass

Gastric bypass vs sleeve vs band: What’s the difference?

Although the purpose of all three weight loss surgeries we offer is to reduce appetite and portion size to ultimately help with weight loss, there are some key differences between these procedures. Below, we explain what you can expect from a gastric sleeve compared to a gastric bypass or band.

The gastric sleeve procedure is normally done as keyhole surgery and involves vertical removal of most of your stomach, which helps to control food intake. Both gastric sleeve and gastric bypass surgeries are irreversible. A laparoscopic sleeve gastrectomy is sometimes recommended over other forms of bariatric surgery if a medical condition would rule them out.

Gastric sleeve surgery is also a little less invasive than gastric bypass, during which the top of the stomach is stapled to create a small pouch which 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.

So, what about a gastric band versus gastric sleeve? One of the main differences is that a gastric band is less invasive than gastric sleeve or gastric bypass surgery. A band is placed around the top of the stomach, which stimulates nerve endings and tricks the brain into thinking the stomach is full. This helps you to feel satisfied on smaller portions.

If you’re wondering whether a gastric sleeve compared to a gastric bypass or band is best for you, we advise booking a free consultation with one of our patient advisors to discuss your weight loss surgery options. They will be able to explain the pros and cons of bariatric sleeve surgery and help you find the best procedure for you and your body.

The main purpose of gastric sleeve, gastric bypass and gastric band surgery is to reduce appetite and portion size, but each is a different kind of surgery.

Gastric sleeve

How does it work?

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

Is it reversible?

No.

Gastric bypass

How does it work?

Both gastric sleeve and gastric bypass surgeries reduce the capacity of your stomach, but a bypass is more invasive than gastric sleeve surgery. During a bypass, the top of the stomach is stapled, creating a small pouch that is then connected to your small intestine. Because the pouch is smaller and the rest of your stomach is bypassed, you will feel full after eating less, meaning your overall appetite will reduce and you may absorb fewer calories from your food.

Is it reversible? 

No.

Gastric band

How does it work?

When considering a gastric band or sleeve, it’s worth noting that the gastric band procedure is 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 will feel more satisfied on smaller portions of food as a result.

Is it reversible? 

Yes.

    What are the sleeve gastrectomy risks?

    As with any major operation, gastric sleeve surgery comes with its own set of risks. When you speak to our experts, they’ll talk through everything you need to know, and answer any questions you may have, to ensure you’re fully aware of the potential sleeve gastrectomy risks and any complications that could arise.

    Our team of surgeons have plenty of experience performing weight loss surgery and supporting their patients afterwards. You can feel completely confident that we’ll conduct your surgery and aftercare with the utmost professionalism.

    Still, it’s important to make yourself aware of the possible vertical sleeve gastrectomy side effects to ensure that, in the unlikely event that something does happen, you’re able to seek treatment as soon as possible. These may include:

    • Blood clots
    • Wound infection
    • Stomach leak
    • Stomach obstruction
    • Malnutrition
    • Gallstones
    • Skin folds or excess skin

    If you notice sudden swelling and inflammation, feel feverish or have nausea after gastric sleeve surgery, seek medical treatment as soon as you can.

    Some people experience a phenomenon known as Dumping Syndrome after gastric sleeve surgery. This is the name given to a range of symptoms experienced after consuming food/fluid containing a lot of carbohydrate (especially sugar).  It occurs because the stomach empties more quickly after gastric sleeve surgery compared with before.

    When you’re deciding whether to have a total gastrectomy, 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

    What is gastric sleeve surgery?

    Gastric sleeve surgery is a weight loss procedure where most of the stomach is removed, reducing its capacity by up to 75%. The area where the hormone that stimulates appetite is produced is also removed. As a result, the food portion size you are able to eat, as well as your appetite, are reduced. It’s important that you make lifestyle changes too, in terms of healthy eating and regular activity, to achieve the best possible results.

    Is there a gastric sleeve diet to follow post-surgery?

    Yes, you’ll need to follow a gastric sleeve diet after your procedure. As 75% of your stomach is removed, naturally your appetite and the portion sizes you can manage to eat will reduce. One of our expert dietitians will advise you on your diet after gastric sleeve surgery, including your food and liquid intake throughout the length of your aftercare. They’ll be able to give you detailed information on what to eat and any foods to avoid after sleeve gastrectomy to ensure you get the desired results following your surgery.

    What are the sleeve gastrectomy risks?

    All surgery comes with the risk of complications, which will be explained to you fully in your consultation, so you are completely aware of what’s involved and can make an informed decision regarding private gastric sleeve surgery.

    Some people may experience Dumping Syndrome after a gastric sleeve procedure. This is the name given to a range of symptoms which can be 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, following your vertical sleeve gastrectomy, side effects like malnutrition and Dumping Syndrome are avoided as far as possible. You’ll also have the opportunity to purchase vitamin and mineral supplements to ensure that you’re getting all the nutrients you need.

    What are the pros and cons of bariatric sleeve surgery?

    Gastric sleeve surgery can completely overhaul your health and overall quality of life. Most people are successful in losing weight following their procedure – with the gastric sleeve weight loss rate as much as 55-60% after three years.

    Losing significant amounts of weight can lead to a happier, more fulfilling life, the 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 is a 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 operations carry some possible complications which will be discussed with you in detail.

    Is gastric sleeve right for me?

    Most patients will need to meet certain criteria for gastric sleeve surgery. As the gastric sleeve procedure is more invasive than a gastric band, but not such a major operation as a gastric bypass, it may suit patients for whom the bypass is inadvisable due to health complications.

    Usually patients must have a certain BMI for gastric sleeve surgery to be suitable, which is typically those with a BMI of 40kg/m2 or over. However, 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).

    It’s important to know that surgery is dependent on a bariatric surgeon’s opinion and your individual circumstances. During your consultation, your surgeon will explain the criteria for a gastric sleeve and discuss whether it’s the most suitable procedure for you.

    How long will I be in hospital after my gastrectomy surgery?

    You will normally stay in one of our specialist hospitals for 2-3 nights after your gastrectomy surgery. Rest assured that our team offer exceptional standards of patient care and all our facilities are registered with the Care Quality Commission.

    What can I eat after my sleeve gastrectomy?

    The sleeve works to reduce portion sizes, rather than restricting specific food types. Compared to the bypass, there are fewer types of food to avoid after a sleeve gastrectomy. However, some patients may struggle with certain textures of food, such as bread or red meat. Our team of experienced dietitians will let you know what to eat after your sleeve gastrectomy to ensure you’re getting all the essential vitamins and minerals you need. It’s important to follow the gastric sleeve diet that your specialist advises to ensure you achieve the results you desire post-surgery.

    Is drinking alcohol after my gastrectomy surgery OK?

    We advise you to avoid drinking alcohol after gastrectomy surgery for at least the first four weeks post-op. Following this, be mindful that your tolerance is likely to reduce. While consuming small quantities of alcohol 1 month after a gastric sleeve is OK, it’s likely you will absorb alcohol into your bloodstream more quickly than before the operation.

    What is Dumping Syndrome after gastric sleeve surgery?

    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 is “dumped” into the small intestine. However, only 1% of patients report their symptoms difficult to manage, and the sensation often occurs less as time passes.

    What is the typical gastric sleeve recovery time?

    The overall gastric sleeve recovery time 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.

    How much weight can you lose after gastric sleeve surgery?

    How much weight you can lose after gastric sleeve surgery will depend on a variety of factors. According to the NHSmore people tend to achieve significant weight loss with a gastric bypass or sleeve gastrectomy than with a gastric band. The gastric sleeve weight loss rate is 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.

    How much is a gastric sleeve?

    Here at The Hospital Group, we understand that every individual has different requirements, which is why we create a bespoke treatment plan in line with your weight loss goals. This means that the gastric sleeve cost may vary, depending on a range of factors. You can use our price check to work out how much your gastric sleeve 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 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.

    We also have 0% finance options allow to spread the sleeve gastrectomy cost over a 6, 10 or 12-month period completely interest-free. Our finance plans are provided by Omni Capital Retail Finance Ltd, regulated by the
