Our specialist bariatric surgeons have performed thousands of weight loss surgery procedures. They will talk you through all the available options and answer your questions.
A sleeve gastrectomy is a type of surgery for weight loss. It is also known as a partial gastrectomy, vertical gastrectomy or gastric sleeve.
It involves permanently reducing the size and capacity of the stomach by about 75%.
The upper part of the stomach is removed as this is where the chemical (ghrelin) that stimulates your appetite is produced. This helps to reduce hunger.
You won’t be able to eat large portions as you’ll feel satisfied with much less.
We understand the decision to have bariatric surgery isn’t one to be taken lightly.
When you’ve tried other ways to lose weight and been unable to maintain long-term results, a sleeve gastrectomy might be an option for you.

Book an appointment
Our dedicated appointments team will arrange for you to meet with one of our renowned surgeons.
During the consultation, you will discuss your expectations and desired results from surgery.
You will need to show us what methods you’ve already tried to lose weight.
Bariatric surgery should always be the last resort. Your surgeon will also outline any risks associated with your procedure.
You will be fully aware of exactly what a gastric sleeve involves.
You’ll have an appointment to review your general health ahead of gastric sleeve surgery. This will help your care team plan your treatment safely.
We will also give advice on your pre-operative diet which you will need to closely follow to prepare for surgery.
There are many pre-requisites of bariatric surgery including body mass index (BMI) which specifically looks at your height to weight ratio.
This will help to determine how healthy you are and whether you are a suitable candidate or not. We will also need to review any current obesity-related conditions.
The day of your operation
You’ll meet your care team who will prepare you for surgery and let you know exactly what to expect throughout the day.
After your operation, your surgeon will check on you and discuss how best to start your recovery.
You should be ready to leave two to three days after your operation. Once you’re home, you’ll have a video check-up with a nurse for dressing changes.
You’ll come back to The London Clinic to have your dressings changed a few weeks later.
After six to eight weeks, you’ll have a follow-up with your surgeon.
They will ensure that your healing is going as expected and you are following your bariatric diet plan without any problems.
A gastric sleeve works by using keyhole surgery to remove around 75% of the total stomach volume. This will reduce your appetite and ability to eat large portion sizes.
It does not change the way food passes through the stomach, unlike gastric bypass surgery.
A gastric sleeve is a type of surgery that removes part of your stomach and requires a general anaesthetic.
Your typical recovery time is a little longer than that after a gastric band. Most patients get back to normal activities in two weeks.
A gastric sleeve surgery takes 1 to 2 hours. After the operation, you will usually require a 2 to 3 day stay with us.
The exact length of your stay depends on your body mass index and the complexity of your case.
Your surgeon will be able to tell you all of these details at your consultation.
The benefits of gastric sleeve surgery include losing weight faster than other weight loss methods, like a gastric bypass or weight loss medication.
But the amount of weight you lose will depend on how committed you are to following a long-term plan of diet and exercise.
Many of our patients achieve long-lasting results. They go on to lose 60% to 70% of their excess weight in the first 12 months after surgery.
This is similar to how much weight you would expect to lose with a gastric bypass in 24 months.
Rather than a weight loss solution, you should view a sleeve gastrectomy as a long-term weight loss management tool. It requires a lot of effort and dedication on your part.
When combined with a healthy diet and exercise, your results can be life-changing.
The part of your stomach which produces an appetite-stimulating hormone will be removed during surgery.
So you will typically feel a lot less hungry after surgery, and this will support your weight loss effort.
Your surgery will restrict the amount of food you can eat in one go and you will find yourself satisfied with smaller portion sizes.
The main advantage of sleeve gastrectomy, over other types of weight loss surgery, is that the way your body digests food won’t change.
This means that there is less chance of becoming deficient in key vitamins, minerals or protein.
You will still need to take supplements in the first two years after surgery, as your food intake will be severely reduced.
Your dietitian will recommend the best vitamins and supplements to support you.
Maintaining a healthy weight can lead to a better quality of life.
It can give you more energy and freedom to enjoy the things you want to do with the people you love the most.
A gastric sleeve can help to treat or reduce the likelihood of obesity-related conditions in future.
These conditions include coronary heart disease, stroke and certain types of cancer.
It's important to remember that you should always weigh up the possible benefits against the risks. This form of weight loss surgery is permanent and irreversible.
Your surgeon will always discuss all risks involved so you can make a fully informed decision.
Your recovery time after gastric sleeve surgery is a little longer than after a gastric band.
Most of our weight loss surgery patients resume normal activities in two weeks following their operation.
You will need to stick to a strict diet that alternates between liquids, purees and soft foods for at least one month.
Your specialist bariatric dietitian will advise you exactly what to eat after your sleeve gastrectomy.
They will provide you with a comprehensive diet plan including any foods to avoid after surgery.
Your surgeon will work with other specialists to give you advice on prehabilitation. This will include things you can do before your operation for a head start on recovery.
We’ll help you recover as fully and quickly as possible by having regular follow-ups with you. We will make sure everything is as expected and answer any questions you may have.
If there’s anything you’re worried about, you can contact your care team at any time.
We know that weight loss isn’t easy, especially on your own. When you’ve tried diet and exercise but it’s just not enough, gastric sleeve surgery with us could be a fresh start.
A sleeve gastrectomy is a major surgical procedure, and it is important to be aware of the possible side effects.
Your surgeon and care team will discuss these with you and make sure you’re well informed about your treatment before you have it.
You can feel confident and reassured that you know what to expect.
The most common side effects of gastric sleeve surgery are:
- Nausea and vomiting
- Acid reflux
- Food intolerances
Dumping syndrome is another one of the potential risks of gastric sleeve surgery.
This sometimes occurs when food moves too quickly through the stomach and is dumped into the small intestine.
Just 1% of sleeve gastrectomy patients find their symptoms are hard to manage. Side effects get better over time after surgery.
You'll be fully supported by our care team to ensure that side effects like malnutrition and dumping syndrome are avoided.
The most serious complications include rupture of the stomach along the line at which the stomach has been stapled.
Bleeding and leakage can occur within 24 to 48 hours after surgery. In the UK, this occurs in fewer than one in 100 patients.
However, the skill of your bariatric surgeon is crucial, and we rarely see such complications at The London Clinic.
A gastric band is intermediate between the gastric balloon and more extensive bariatric surgery
