The Gastric Sleeve Loss Surgery


What is the gastric sleeve? Back to top

Gastric Sleeve Weight Loss Surgery

The gastric sleeve also know as a vertical sleeve gastrectomy is a surgical bariatric procedure in which the stomach is reduced by 75% of its original size. The Gastric Sleeve weight loss surgery is a permanent and non-reversible procedure. When required, in a subsequent weight loss procedure, the gastric sleeve can be converted to a gastric bypass. Gastric Sleeve are generally performed in patients who are considered at a high risk for a gastric bypass or a duodenal switch.

At Harley Street Bariatrics, we offer weight loss surgeon lead care packages, based in Harley St, London, UK. This means the patient has constant and unlimited access to their surgeon and supporting bariatric team for follow up appointments and advice for up to 2 years.
Exact costs are given after your first consultation and medical assessment with the surgeon. The all inclusive cost of the gastric sleeve is from £13,000. To find out more, please feel free to contact us.
The initial consultation with the bariatric surgeon is £250 which is deductible from the surgical package price when patients go ahead with surgery.
All of our weight loss procedures and surgeries are performed in London based private hospitals.


Who are the best candidates? Back to top

The gastric sleeve weight loss surgery is generally best suited to people who are obese with a BMI (Body Mass Index) greater than 40, although in some case those with a BMI of between 30 and 40 may be suitable. The suitability of the patient will be determined at the time of the consultation by the surgeon.
* You can calculate your BMI on our main page *( please click here )

Other important factors for the requirements of the gastric sleeve weight loss surgery:


  •     You have been overweight for over five years.
  •     Your weight-loss attempts have had only short term success, for example “yo yo” dieting
  •     You are not suffering from any other disease that may have caused your weight gain.
  •     You are prepared to make a daily commitment and change in your eating habits and lifestyle.
  •     You are willing and eager to being monitored by the specialist treating you.
  •     You do not drink alcohol in excess.
  •     You do not smoke.

At the time of your consultation, you will be carefully assessed by the weight loss surgeon as each individual is different in anatomy and the BMI is rough estimates not taking into account large bone and muscle mass.

How does it the gastric sleeve work? Back to top

The gastric sleeve also know as a vertical sleeve gastrectomy is a surgical bariatric procedure in which the stomach is reduced by 75% of its original size. The new stomach, which looks like a sleeve, restricts and significantly decreases the the amount of food that can be eaten at one time.
The gastric sleeve surgery effectively restricts the stomach capacity without affecting its function.

How is the gastric sleeve weight loss surgery carried out? Back to top

The gastric sleeve weight loss surgery is performed through “keyhole surgery” also know as laparoscopic surgery. “Keyhole surgery” is the preferred method to reduce scars and overall recovery time. The bariatric surgeon creates a smaller stomach, a sleeve,  with a medical stapling device. Once the sleeve is created, the rest of the stomach is removed through one of the incisions or “key-holes”.
The operation takes usually between 1.5 to 3 hours under a general anesthetic depending on the patient. You will be required to stay two nights in the hospital.

How long does the recovery from a gastric sleeve operation take?Back to top

We advise taking at least one week off as you will be adjusting from the surgery and your new diet plan. The first two weeks you will need to go through a transition of fluids (ie: smoothies) to puree back to solids.
You will be followed and advised by your surgeon.
After two weeks, you will come back for a wound check. The sutures are generally dissolvable.

What are the benefits and risks? Back to top

The main benefits are:

  •  Eliminates the portion of the stomach that produces the hormones that stimulates hunger (Ghrelin). Hunger pains are significantly reduced.
  • Significantly reduces the portions of foods and overall daily calorie intake. Supports eating smaller meals 3 – 5 times a day, thus increasing the overall metabolic rate.
  • Dumping syndrome is avoided or minimized because the pylorus is preserved.
  • By avoiding the intestinal bypass, almost eliminates the chance of intestinal obstruction (blockage), marginal ulcers, anemia, osteoporosis, protein deficiency and vitamin deficiency.
  • Alternative option for patients who are concerned about the complications of the gastric bypass surgery  and/or are at a too high risk for intestinal bypass procedures.
  • Alternative option for patients who are concerned about the foreign body aspect of the gastric band.
  • Is performed  laparoscopically, thereby providing all the advantages of minimally invasive surgery: fewer wound and lung problems, less pain, and faster recovery.

The main risks are:

  • Potential for inadequate weight loss or weight regain. While this is true for all procedures, it is theoretically more possible with procedures that do not have an intestinal bypass. The gastric bypass generally offers a higher potential for weight loss than the gastric sleeve.
  • Higher BMI patients will most likely need to have a second stage procedure later to help lose the rest of the weight. Remember, two stages may ultimately be safer and more effective than one operation for higher BMI patients.
  • This procedure does involve stomach stapling and therefore leaks and other complications related to stapling may occur.
  • Because the stomach is removed, it is not reversible. It can be converted to almost any other weight loss procedure.
  • Infection – antibiotics are usually given to prevent infection.
  • Damage to other organs in your abdomen – you may need further surgery to repair any damage.

All surgeries carry risks. The experience and skill the surgeon plus careful screening of each prospect can significantly lower these risks.
