Gastric Sleeve Surgery
Conveniently located to serve London, Greater London, Birmingham, and Manchester.
Patients seeking a highly effective solution for weight loss are encouraged to consider gastric sleeve surgery in London with Mr. Georgios Vasilikostas, a leading expert in bariatric procedures. Gastric sleeve surgery, also known as sleeve gastrectomy, offers superior weight-loss outcomes compared to options such as gastric band weight reduction, gastric balloons, or weight-loss medications.
This transformative procedure can help patients of the GV Weight Loss Clinic in London lose up to 60% or more of their excess weight or around 35% of their total weight. Weight loss typically occurs rapidly during the first three to six months, with continued progress over a two-year period. Thanks to the lifestyle changes incorporated into this journey, patients can maintain their results for the long term, enjoying improved health and vitality.
What IsGastric Sleeve Surgery?
Gastric sleeve surgery, or sleeve gastrectomy, is a minimally invasive weight-loss procedure that removes approximately 75–80% of the stomach, leaving a smaller, sleeve-shaped stomach. This significantly reduces the amount of food the stomach can hold, helping patients feel full faster and consume fewer calories.
In addition to the physical changes, gastric sleeve surgery triggers hormonal adjustments in the gut. By removing the part of the stomach that produces ghrelin (the “hunger hormone”), patients experience fewer cravings and improved satiety, making portion control easier and sustainable.
This procedure is typically performed laparoscopically, which means it requires only small incisions, leading to shorter recovery times and reduced risks compared to open surgery.
Ideal Candidates for Gastric Sleeve Surgery
Ideal gastric sleeve candidates have a BMI of 40 or higher. If patients have a BMI above 35 or sometimes even lower with comorbidities like Type 2 diabetes, they may also be eligible candidates.
Candidates for a gastric sleeve procedure must be ready to make lifelong changes to their diet and exercise regimen. Patients must also be willing to come in for regular follow-up appointments.
Smokers are strongly encouraged to stop smoking before the date of their gastric sleeve surgery to decrease the risk of complications and improve results.
Benefits of Gastric Sleeve Surgery
Gastric sleeve surgery is one of the most effective tools for sustained weight management. Key benefits include:
- Significant Weight Loss: Achieve substantial and lasting weight reduction, improving overall health and reducing obesity-related risks.
- Health Improvements: Many patients see improvements in conditions such as type 2 diabetes, high blood pressure, and sleep apnoea.
- No Foreign Objects: Unlike gastric banding, the procedure does not involve implanting devices, reducing the risk of complications.
- Improved Quality of Life: Increased energy levels, enhanced mobility, and a boost in self-confidence are common outcomes.
- Reduced Appetite: By removing the portion of the stomach that produces hunger-stimulating hormones, patients feel full faster and eat smaller portions.
The Gastric Sleeve Consultation
During the patient’s consultation with Mr. Vasilikostas, the patient will discuss their weight-loss goals in great detail. Mr. Vasilikostas will perform a physical examination and make enquiries regarding various lifestyle factors. The patient’s medical history will be discussed, including all pre-existing health conditions and allergies.
Mr. Vasilikostas will talk to the patient about the gastric sleeve procedure and what it can do for them. He will give them preparation instructions and tell them about the surgical process, recovery, and the weight-loss benefits of gastric sleeve surgery.
A personalised diet and exercise plan will be created for the patient. Patients can feel free to ask any questions they may have. Finally, a date will be set for the surgery.
The Gastric Sleeve Procedure
A gastric sleeve procedure takes one to two hours to perform. At the start, general anaesthesia is administered in order to ensure comfort and prevent pain.

Next, incisions are created in the abdomen. Laparoscopic incisions are quite small, resulting in a shorter recovery time.
Laparoscopic gastric sleeve surgery involves insertion of a laparoscope into an incision. A laparoscope is a thin tube with a camera and a light. The camera transmits images to an external monitor, allowing the doctor to analyse internal structures with a high degree of detail.
Next, the surgeon staples the stomach vertically. This results in a thin pouch, which is 15% to 20% of the stomach. The remaining 75% to 80% of the stomach is carefully removed. The laparoscope is withdrawn, and then the incisions are closed using medical glue.
After Gastric Sleeve Surgery
Once the patient’s gastric sleeve procedure is complete, the recovery process will begin. The patient will be monitored for one to two nights until they are cleared to return home. Pain-control medication will be administered as needed.

Patients can shower immediately after returning home. Gastric sleeve incisions will heal naturally over time. Patients are instructed to keep the incisions clean and dry. After a few days, they will be able to peel off the medical glue.
Following the operation, patients will need to follow a staged diet, which may vary from patient to patient. Our specialist bariatric dieticians provide patients with all the necessary information before and after the procedure.
Generally, patients start with a diet of sugar-free non-carbonated liquids for two weeks. After this, patients will be able to eat pureed foods for around two weeks. They will then switch to a soft diet for around two weeks. Once this period is over, patients can resume a solid-food diet.
Additionally, patients will need to take multivitamins and mineral supplements in the long term. Patients will receive more detailed information from our dieticians based on their specific case.
During the first three to six months, patients may experience minor temporary side effects, including aches, cold sensations, and feelings of fatigue. Equally, they feel more energized due to the weight loss and its positive impact on their lives. Patients will be given regular follow-ups to support them through their journey, maximize the results, and recognise any issues as early as possible.
The Cost of Gastric Sleeve Surgery
The cost of gastric sleeve surgery varies depending on the patient’s medical history. Each patient’s personal support needs can also play a role in determining the overall price. Customised price packages are available, as well as financing options.
