Gastric Bypass Surgery
Conveniently located to serve London, Greater London, Birmingham, and Manchester.
What isGastric Bypass?
The gastric bypass is one of the most trusted and well-established bariatric surgery procedures. This procedure affects the release of certain hormones associated with hunger. This creates a feeling of satiety after consumption of a smaller amount of food. This feeling is also present for a longer time. Additionally, as a result of gastric bypass surgery, the number of calories and amount of fat absorbed during the eating process are greatly reduced.
Patients who properly follow their personalized diet and exercise programme after their procedure has lost up to 80% of their excess weight over the course of two years. This can equate to 30% to 35% of the patient’s total body weight. The weight loss achieved through these surgeries is greater than that achieved through adjustable gastric band placement, endoscopic sleeve gastroplasty, gastric balloons, and weight-loss medications.
The gastric bypass is the optimal surgery for treatment of gastroesophageal reflux disease. Gastric bypass surgery can also aid in treatment of a number of other health issues, such as Type 2 diabetes, infertility, high blood pressure, sleep apnoea, heart disease, and high cholesterol.
The Gastric Bypass Consultation
During a consultation with Mr. Vasilikostas, the patient will express their weight-reduction goals. The patient and Mr. Vasilikostas will discuss the patient’s overall health, including such factors as their complete medical history and numerous aspects of their diet and lifestyle. Mr. Vasilikostas will perform a physical examination, and lab tests may be ordered.
The potential benefits of a gastric bypass will be discussed, along with the weight-loss process associated with it. Questions are highly encouraged at any time during the consultation process.
Mr. Vasilikostas and our highly experienced staff of health professionals will create a personalised diet and exercise plan for the patient. These lifestyle changes can aid the patient in long-term maintenance of weight-loss results.
The Gastric Bypass Surgical Process
A Roux-en-Y gastric bypass (RYGB) requires anywhere from 50 minutes to two hours to perform. On average, the procedure is performed in one and a half hours. At the beginning of the procedure, general anesthesia is administered for patient comfort.

Once the general anaesthesia has taken effect, Mr. Vasilikostas creates four to five precise upper-abdominal incisions. These incisions are quite small and are called keyhole incisions. An instrument called a laparoscope is then inserted. This instrument provides a magnified view of the area on an external monitor.
Mr. Vasilikostas utilises an instrument known as a laparoscopic stapler to place staples in the upper part of the stomach. This results in a new egg-sized stomach pouch, which can only accommodate one ounce of food. Normally, the stomach can accommodate up to three pints of food.
The larger portion of the stomach (80% of the original stomach) remains in the abdomen. Its secretion of digestive enzymes is not interrupted. However, food no longer travels through it.
Once Mr. Vasilikostas creates the smaller stomach pouch, he then creates a tiny opening in the pouch and sutures a section of the jejunum, or small intestine, to the opening. This connection is known as an anastomosis, and it routes food directly from the pouch to the central section of the jejunum.
Mr. Vasilikostas then connects the other end of the small intestine to another section of the small intestine, creating another anastomosis. The resulting stomach-intestine structure has a Y shape, which gives the procedure its name.
Once these changes have been achieved, all tools are withdrawn, and then the incisions are closed with the aid of surgical sutures or clips.
The Recovery Process Following a Gastric Bypass
The patient is closely monitored after their surgical session. A hospital stay of one to two days is required before patients can receive clearance to return home. It will be necessary for the patient to be driven home by a companion or family member, as driving will be prohibited at this time.

During recovery, patients must follow a liquid diet for two weeks, which shifts to a pureed-food diet for a period of one to two weeks. After this, patients adopt a soft-food diet for one to two weeks. Patients can then resume a normal solid-food diet as directed.
Minor swelling, tenderness, bruising, numbness, itching, or tingling may be experienced at the incision sites. These issues will subside in time. Pain may be experienced at the incision sites, which can be addressed with the aid of medication as directed.
Patients receive clearance to return to their workplace within seven to 14 days following their procedure. Many other normal activities can be resumed at this time. Heavy exercise and other strenuous activities are prohibited for four to six weeks. Less strenuous exercises can be resumed gradually until patients return to high-impact exercises such as weight training.
Women must practise proper contraception for a year to a year and a half following their procedure. This ensures effective healing and weight reduction.
For proper nutrition, lifelong vitamin and mineral supplements will be necessary, including iron, multivitamins, calcium, and vitamin B12 supplements. To evaluate nutrient levels, blood tests must be performed every six to 12 months.
Over the following three to six months, patients will experience rapid weight loss. They may also experience temporary side effects such as dry skin, cold sensations, aches, fatigue, and mood changes. Patients may experience a degree of hair loss for the first six months, but this is almost always temporary. They may also experience the formation of loose skin.
Patients will be required to return for follow-up appointments so that Mr. Vasilikostas can evaluate their weight-loss progress. To achieve sustained weight reduction, patients must follow their recommended lifestyle changes, including a healthy diet and regular exercise.
The Cost of a Gastric Bypass
The cost of a gastric bypass procedure may vary based on several factors. The patient’s medical history can play a role, as can their various support needs. The price of this procedure may be discussed with Mr. Vasilikostas as part of one’s consultation. We also offer tailored pricing packages based on each patient’s personal needs.

FrequentlyAskedQuestions
Am I a good candidate?
The optimal candidates for gastric bypass surgery are interested in an effective surgical weight-reduction solution. Patients who have been unable to achieve effective weight-loss results through traditional diet and exercise may find these procedures to be ideal options.
To be an optimal candidate for a gastric bypass, patients must have a BMI of 40 or higher. Patients who suffer from serious weight-related medical issues and have a BMI of between 30 and 40 are also excellent candidates.
Candidates with Type 2 diabetes often benefit strongly from this procedure, experiencing a quick resolution of their condition; some patients experience this change as soon as a single day after their procedure. Patients with acid reflux and high blood pressure can also benefit greatly from this surgery.
Patients who have undergone one or more abdominal surgeries or who plan to become pregnant within 12 months are not ideal candidates for the gastric bypass procedure.
How do I prepare for gastric bypass surgery?
Prior to gastric bypass surgery, patients will be strongly encouraged to stop smoking. For two weeks prior to the session, they may be instructed to adopt a liver-shrinking diet. These changes greatly reduce the potential for various health complications.
What is dumping syndrome?
Dumping syndrome is a condition that may occur following gastric bypass surgery. This causes patients to feel light-headed as a result of consumption of foods that are higher in sugar, starch, or fat.
