Gastric Bypass Surgery in Turkey
The gold standard for significant, sustained weight loss, from £3,160, with 5-star accommodation, transfers, and 12 months of aftercare.
If you have a higher BMI or obesity-related health conditions, particularly type 2 diabetes, a gastric bypass may be the most effective treatment for you. It is considered the gold standard of bariatric procedures, with decades of clinical evidence supporting its safety and effectiveness.
A gastric bypass works in two ways. First, it creates a small stomach pouch that limits how much you can eat. Second, it reroutes a portion of your small intestine so your body absorbs fewer calories from food. This dual mechanism means patients typically lose more weight, more quickly, than with other bariatric procedures, and the results tend to be especially powerful for improving type 2 diabetes, often leading to full remission.
Most patients lose 70-80% of their excess body weight within 12-18 months, with many seeing significant health improvements within weeks of their procedure.
At The Health Store Turkey, your gastric bypass package covers everything: your procedure in a JCI-accredited hospital, 3-4 nights of hospital care, 5-star hotel accommodation, private airport transfers, a personal translator, and 12 months of dedicated aftercare. From £4,500, fully inclusive. No hidden costs.
What Is Gastric Bypass Surgery?
How a Gastric Bypass Works
A gastric bypass (formally known as a Roux-en-Y gastric bypass) involves two steps, both performed laparoscopically through small keyhole incisions:
- Creating a smaller stomach pouch. Your surgeon divides your stomach, creating a small pouch roughly the size of an egg. This dramatically reduces how much food you can eat at each sitting.
- Rerouting the intestine. A section of your small intestine is then connected directly to the new pouch, bypassing a significant portion of your digestive tract. This means your body absorbs fewer calories and less fat from the food you eat.
The procedure takes approximately 60-90 minutes under general anaesthesia. Because it is performed laparoscopically, you benefit from smaller incisions, less discomfort, and a faster recovery than traditional open procedures.
Why Is It So Effective?
The gastric bypass is the only bariatric procedure that works through both restriction (smaller stomach) and malabsorption (fewer calories absorbed). This combination delivers:
- Greater total weight loss, typically 70-80% of excess body weight
- Faster initial results, many patients notice significant changes within the first month
- Powerful metabolic effects, particularly on type 2 diabetes, with remission rates of up to 80% in eligible patients
- Reduced hunger hormones, changes to your gut hormones help suppress appetite naturally
For patients with a BMI over 40, or a BMI over 35 with serious obesity-related conditions, the gastric bypass is often the recommended treatment.
Am I Suitable?
A gastric bypass may be right for you if:
- Your BMI is 35 or above with obesity-related health conditions (such as type 2 diabetes, high blood pressure, or sleep apnoea)
- Your BMI is 40 or above, regardless of other conditions
- You have tried to lose weight through diet, exercise, or other methods without lasting success
- You are committed to the long-term dietary and lifestyle changes required after your procedure
- You are generally fit enough for a procedure under general anaesthesia
The gastric bypass is often particularly recommended for patients with type 2 diabetes, as the metabolic changes it produces can dramatically improve, and in many cases completely reverse, insulin resistance.
You may not be suitable if you have certain gastrointestinal conditions (such as Crohn's disease), are a heavy smoker unwilling to stop before your procedure, are pregnant or planning pregnancy within 12-18 months, or have unmanaged psychological health concerns.
Your free consultation includes a thorough medical review. Your patient coordinator will assess your BMI, health history, current medications, and personal goals to confirm whether a gastric bypass is the right choice, or whether another procedure, such as a gastric sleeve, might better suit your situation. There is no obligation and no pressure.
What Happens During the Procedure?
Before Your Procedure
Everything begins with a free consultation, by phone, video call, or at one of our UK consultation days. Your patient coordinator will discuss your goals, talk through your medical history, and explain the procedure step by step.
Once you decide to proceed, your team arranges everything: flights, hotel, hospital scheduling, and pre-operative preparation. You will receive a detailed guide explaining the 2-3 week liver-shrinking diet you need to follow before your procedure. This is an important step, it reduces the size of your liver, giving your surgeon better access and making the procedure safer.
On the Day
You will arrive at the hospital having fasted overnight. Your care team will greet you, complete final blood tests and checks, and your anaesthetist will explain exactly what to expect.
The procedure takes approximately 60-90 minutes under general anaesthesia. You will be asleep throughout and will not feel or remember anything.
After Your Procedure
You will spend 3-4 nights in hospital. This slightly longer stay (compared to a gastric sleeve) allows your medical team to carefully monitor your recovery and ensure the new connections in your digestive system are healing properly.
A leak test is performed before you begin taking fluids, confirming everything is sealed and functioning as it should. Your personal translator is with you throughout, ensuring clear communication with your medical team at all times.
Once discharged, you will continue your recovery at your 5-star hotel with 24/7 access to your patient coordinator. When you are ready, your private transfer takes you back to the airport.
Recovery & Aftercare
What to Expect During Recovery
Recovery from a gastric bypass takes slightly longer than a gastric sleeve, but most patients are surprised by how quickly they feel better. You can typically return to light daily activities within 10-14 days and resume full work after 3-4 weeks.
Week 1-2: A strict liquid diet while your stomach and intestinal connections heal. Some discomfort and tiredness are normal. Pain is managed with prescribed medication. Light walking is encouraged from the day after your procedure, it is one of the most important things you can do for your recovery.
Week 2-4: Gradual progression to soft, pureed foods. Energy levels improve, and most patients start to see noticeable weight loss at this stage. You may feel emotional as your body adjusts, this is completely normal and temporary.
Month 2-3: You begin transitioning to small, regular solid meals. Portions are much smaller than before, and you may find that very sugary or fatty foods cause discomfort (known as "dumping syndrome"). This is actually a helpful side effect, it naturally discourages unhealthy eating habits.
Month 3-12: Consistent, steady weight loss continues. Most patients lose the majority of their excess weight within 12-18 months. Your aftercare team supports you through every phase, adjusting your dietary plan and supplement routine as needed.
Your 12-Month Aftercare Programme
Your care continues long after you return home:
- Regular check-ins with your dedicated aftercare team
- Detailed dietary guidance for each phase of recovery
- Supplement and vitamin monitoring (particularly important with a gastric bypass)
- Free sports and fitness access for 12 months
- Blood test guidance to monitor nutritional levels
- Direct access to your patient coordinator whenever you have questions
Risks & Considerations
Being transparent about risks is part of giving you the honest information you need to make the right decision. A gastric bypass is a well-established procedure with decades of safety data, but like any treatment performed under general anaesthesia, it carries some risks.
Common Side Effects (Temporary)
- Nausea and discomfort in the first few days (managed with medication)
- Fatigue and low energy during the liquid diet phase
- "Dumping syndrome", feeling dizzy, sweaty, or nauseous after eating sugary or fatty foods. This occurs in approximately 15-20% of patients and is usually temporary. Many patients view it as a helpful deterrent.
- Changes in bowel habits as your body adjusts to the new digestive route
Less Common Risks
- Infection at incision sites (minimised by JCI hospital hygiene protocols)
- Blood clots (reduced through early mobilisation, compression stockings, and blood-thinning medication)
- Internal leaking at the surgical connections (occurs in approximately 1-3% of cases; this is why your hospital stay is 3-4 nights, with a leak test before you begin fluids)
- Nutritional deficiencies, more significant than with a gastric sleeve, because your body absorbs fewer nutrients. This is managed with a lifelong supplement routine and regular blood monitoring.
- Internal hernias (rare, occurring in 1-2% of cases over time; symptoms are monitored during your aftercare)
How Your Risk Is Managed
Your procedure is performed in a JCI-accredited hospital with full intensive care facilities. Your surgical team has extensive experience with gastric bypass procedures, using advanced laparoscopic techniques. The 3-4 night hospital stay allows thorough monitoring, and the leak test provides confirmation before you begin oral intake. Your 12-month aftercare programme includes nutritional monitoring specifically designed for gastric bypass patients.
Every patient has concerns, that is a sign of someone making a thoughtful decision. Your patient coordinator is available to talk through any specific worries, openly and honestly.

Frequently Asked Questions
Most gastric bypass patients lose 70-80% of their excess body weight within 12-18 months. For example, if you are 8 stone overweight, you could expect to lose 6-7 stone. Weight loss is typically fastest in the first 6 months and then gradually stabilises. The gastric bypass generally produces greater total weight loss than a gastric sleeve, particularly for patients with a higher starting BMI. Your long-term results depend on following the dietary guidelines and attending your aftercare appointments.
In many cases, yes, dramatically. Clinical studies show that up to 80% of type 2 diabetes patients experience complete remission after a gastric bypass, meaning they no longer need diabetes medication. This is because the procedure changes the way your body processes insulin and glucose, not just through weight loss but through direct metabolic effects on your gut hormones. Improvements often begin within days of the procedure, well before significant weight loss has occurred. Your medical team will monitor your blood sugar levels closely and adjust your medication as needed throughout your recovery.
Both procedures reduce the size of your stomach, but a gastric bypass also reroutes part of your small intestine. This means it works through both restriction (smaller stomach) and malabsorption (fewer calories absorbed). The gastric bypass typically produces greater total weight loss and has stronger effects on type 2 diabetes. However, it is a more involved procedure with a slightly longer recovery and a greater need for lifelong vitamin supplements. The gastric sleeve is simpler, has a shorter recovery, and is often recommended for patients with a lower starting BMI. Your consultation will help determine which procedure is the right fit for you.
Yes. Because the gastric bypass changes how your body absorbs nutrients, you will need to take daily supplements for the rest of your life. This typically includes a multivitamin, vitamin B12 (often as a monthly injection or daily sublingual tablet), iron, calcium with vitamin D, and sometimes additional supplements depending on your blood test results. Your aftercare team will set up your supplement plan and guide you through the first 12 months. Most patients find it becomes second nature within a few weeks, a small daily commitment for a life-changing result.
Plan for 6-8 days in total. This includes 3-4 nights in hospital following your procedure, plus 2-3 nights at your 5-star hotel for continued recovery. Your patient coordinator will help you arrange flights and timing to make everything as smooth as possible. Some patients choose to add an extra recovery day before flying, though most feel comfortable travelling after 6-7 days. Your personal translator and patient coordinator are available throughout your entire stay.
