Weight Loss and Gastric Sleeve Guide for UK Patients

Considering weight-loss treatment abroad involves more than comparing a headline price or a before-and-after photograph. UK patients need to understand which treatment is being discussed, who will assess and treat them, what the written package includes, how complications would be managed and who will provide follow-up after they return home.

This guide brings the main Istanbul Obesity Center resources into one clear pathway, with gastric sleeve surgery in Turkey as the primary focus. It is general information, not a diagnosis or a promise that surgery is suitable. A decision should follow an individual clinical assessment, informed consent and a realistic UK aftercare plan.

Gastric Sleeve Is One Option, Not an Automatic Answer

Sleeve gastrectomy permanently removes part of the stomach and leaves a narrower stomach tube. It is different from gastric bypass, an intragastric balloon, endoscopic sleeve gastroplasty and prescription weight-management medicines. These options differ in anatomy, evidence, reversibility, nutritional effects, procedure-specific risks and follow-up needs. No single treatment is best for every person.

The Fixed £1,800 Primary Gastric Sleeve Package

For a suitable primary gastric sleeve patient, the fixed package price is £1,800. The planned package includes two hospital nights, one hotel night, interpreter support, planned local transfers and one year of dietitian follow-up with Aylin Demir. The price should be confirmed in writing for the individual patient before travel.

Flights, travel insurance and UK or external tests, consultations or treatment are not included unless they are specifically added in writing. Revision surgery, bypass, balloon treatment and care made necessary by an additional finding or complication require separate assessment and written pricing. Read the full gastric sleeve cost and package guide before comparing IOC with another provider.

Who Does What?

  • Kenan Afilitak, general surgery specialist: leads surgical assessment, discusses options and risks, and is responsible for the surgical consent pathway. See the Kenan Afilitak profile.
  • Aylin Demir, dietitian: supports the planned nutrition pathway and the package’s one-year dietitian follow-up. This does not replace lifelong monitoring in the UK.
  • Mustafa Hekin, clinic coordinator: helps coordinate written package, appointments and travel information. A coordinator does not diagnose, prescribe, choose an operation or replace emergency care.

Patients should know the named hospital, named surgeon, planned procedure and responsible clinical contact before paying or travelling. Marketing messages should never be treated as clinical consent.

Step 1: Individual Assessment Before Booking

A safe assessment is not based on BMI alone. Relevant information may include previous operations, current conditions, medicines and allergies, sleep apnoea, reflux, diabetes, blood-clot history, smoking or nicotine, alcohol, pregnancy plans, mental health, eating behaviour, mobility, nutrition and the ability to attend follow-up. The clinical team decides which tests and specialist opinions are needed; a website should not give every patient the same test list or medicine-stopping instruction.

Be open about prescribed, over-the-counter and recreational substances. Do not stop anticoagulants, diabetes medicines, weight-loss injections or other treatment because of a generic online timetable. The prescribing and surgical teams should give an individual plan.

Step 2: Prepare for Surgery and the Return to the UK

Some patients receive a preoperative liver-reduction diet, but its length and content should come from the treating dietitian or surgical team. The pre-bariatric surgery diet guide explains the purpose without prescribing a universal menu.

  • Confirm the hospital, surgeon, procedure and anaesthetic plan in writing.
  • Confirm what the £1,800 package includes and what could create an additional charge.
  • Arrange travel insurance that accurately reflects planned treatment; check exclusions and repatriation terms.
  • Plan enough time in Turkey for assessment and clinical clearance to travel, rather than relying on a fixed “safe to fly” day.
  • Identify who can accompany or support you, and how you would access urgent help after returning home.
  • Bring medicines in original packaging and follow airline rules for medical equipment or injections.

For travel-specific questions, use the travel after bariatric treatment guide. A treatment trip should not be planned as an ordinary holiday.

Step 3: Hospital, Discharge and Hotel

The planned sleeve package provides two hospital nights followed by one hotel night, subject to clinical decisions. A longer stay, different pathway or additional treatment may be needed if recovery is not proceeding as expected. Discharge should be based on the clinical picture, not only the travel booking.

Before leaving Turkey, ask for the operation note, discharge summary, medicine and supplement plan, test results, pathology arrangements where applicable, wound advice, diet-stage instructions, emergency contact route and fit-to-travel decision. Keep both digital and paper copies available for UK clinicians.

Step 4: Eating, Drinking and Supplements

After sleeve surgery, diet normally progresses through texture stages, but services use different names and timelines. Follow your own written plan rather than advancing because another patient did. Hydration, slow eating, tolerance and food-first protein are important, but exact targets should be individualised. The main nutrition after gastric sleeve guide, protein guide and breakfast guide explain these principles in more detail.

Repeated vomiting, inability to keep fluids down, progressive difficulty swallowing or new neurological symptoms are not problems to manage by repeatedly changing a meal plan online. They need prompt clinical assessment.

Step 5: Lifelong Follow-Up in the UK

One year of dietitian support is useful, but bariatric follow-up does not end after one year. UK guidance supports long-term nutritional surveillance and lifelong annual monitoring after discharge from a specialist bariatric service. The exact blood tests and supplement doses depend on the operation, results, symptoms and individual clinical history.

Use the blood tests after gastric sleeve guide to prepare a discussion with your GP or bariatric service. Do not wait for symptoms before arranging routine follow-up, because some deficiencies can develop quietly.

Risks, Warning Signs and Emergency Planning

Possible early complications include bleeding, leak, infection, blood clots, dehydration and breathing problems. Later issues can include reflux, narrowing, gallstones, nutritional deficiency, food intolerance and weight regain. Risk varies, and listing a complication does not predict whether it will happen to one person.

Seek urgent clinical advice for worsening abdominal or chest pain, persistent fast heart rate, fever or feeling severely unwell, repeated vomiting, inability to keep fluids down, increasing difficulty swallowing, black stools or vomiting blood, wound redness with systemic illness, or a swollen painful leg. Call 999 or go to A&E for severe breathing difficulty, collapse, major bleeding or another emergency. Use NHS 111 or urgent GP care when prompt advice is needed but it is not an immediate life-threatening emergency. Contact IOC as well, but WhatsApp and the website contact form are not emergency services.

More detailed topic guides include reflux after gastric sleeve, scar and wound healing and leak testing and its limits.

Results, Plateaus and Weight Regain

No clinic can guarantee an exact kilogram, stone, dress size, BMI or health outcome. Results differ with starting point, biology, health conditions, medicines, nutrition, activity, sleep, follow-up and complications. Before-and-after photographs are selected examples, not a forecast for another patient.

Read the gastric sleeve results guide, plateau guide and weight-regain review guide. A plateau or regain should prompt a structured clinical, dietary and behavioural review rather than blame or an automatic revision operation.

UK Patient Decision Checklist

  • Do I know the exact operation and why it may be suitable for me?
  • Have I discussed alternatives, uncertainties and procedure-specific risks with the clinician responsible?
  • Do I have the named surgeon, hospital and clinical contact details?
  • Is the full £1,800 scope and every exclusion written down?
  • Do I understand that flights, insurance and UK or external care are outside the package unless added in writing?
  • Do I have a complication, insurance and repatriation plan?
  • Will I receive operation, discharge, medicine, supplement and test records before returning home?
  • Who will provide routine blood monitoring, prescriptions and urgent assessment in the UK?
  • Am I being offered realistic information rather than a guaranteed result or pressure to pay quickly?

Request an Individual Assessment

If you would like to discuss primary gastric sleeve surgery, use the IOC contact page to request an assessment and written package information. Share your medical history accurately and ask for any unclear inclusion, exclusion or aftercare responsibility to be confirmed before booking.
