In gastric sleeve (sleeve gastrectomy), about 70-80% of the stomach is removed laparoscopically (through 4-5 small incisions). The remaining stomach is tube-shaped and holds about 100-150 ml. The operation lasts 60-90 minutes under general anaesthesia. You stay 2-3 days in hospital for pain control and the start of the diet.

The cost of aesthetic treatments in Turkey ranges between €1,500 and €10,000, depending on factors such as the type of procedure, the clinic's quality, and the expertise of the medical team. While lower prices may seem appealing, it is crucial not to compromise your health. At Mapa Health, we prioritize your safety and deliver exceptional results without cutting corners.

What your journey feels like

Day by day with bariatric surgery in Istanbul

Bariatric surgery is a major operation and requires a 5- to 7-day stay. Here is the typical schedule — your individual journey depends on the procedure (sleeve, bypass, balloon), starting condition and healing.

DAY 1

Arrival & pre-op assessment

  • 08:30
    Landing in Istanbul

    Mapa driver in arrivals with a "Mapa Health" sign.

  • 11:00
    Hotel check-in

    5-star partner hotel near the hospital.

  • 14:00
    Clinic: pre-op assessment

    Blood tests, ECG, lung function, endoscopy, anaesthesia consultation. Confirmation of the planned procedure (sleeve or bypass).

  • 18:00
    Last meal

    Fasting from midnight. The pre-op liver diet has ideally already been started at home.

DAY 2

Surgery day

  • 07:00
    Hospital admission

    Admission examination, consent, gown. You have time for questions.

  • 09:00
    Bariatric surgery

    General anaesthesia, laparoscopic (5 small incisions). Sleeve or bypass takes 60 to 90 minutes. You wake up in recovery without consciously experiencing the procedure.

  • 13:00
    First hours

    Mobilisation (standing, a few steps) is important to prevent thrombosis. Pain control with IV medication.

  • 20:00
    First sips of water

    After radiological leak test you may take small sips of water.

DAY 3-5

Hospital & hotel

  • Day 3
    Abdominal pain eases

    You can walk longer distances on the hospital corridor. Clear liquids in small sips — water, unsweetened tea, clear broth.

  • Day 4
    Hospital discharge

    Off to the hotel with pain medication, anti-thrombosis injections, vitamins and a diet plan. Mapa staff check on you regularly.

  • Day 5
    Hotel recovery

    Liquid diet continues, lots of sleep, short walks. Wound check at the clinic.

DAY 6-7

Travel clearance & trip home

  • Day 6
    Final follow-up

    Blood tests, wound check, final medical examination. Written surgical report, vitamin prescription, diet plan, travel clearance.

  • Day 7+
    Trip home

    Compression stockings for the flight, movement on the plane, plenty of fluids. First follow-up with your GP at home after 1 week.

What if...?

"What if complications occur during surgery?"

Bariatric surgery has a low complication rate (1 to 3 percent), but it is not zero. In an emergency the hospital is available 24/7 and the surgeon reachable. A written warranty for re-operation in case of surgery-related complications should be on file before the trip.

"What if I am afraid of general anaesthesia?"

This worry is common. Before surgery you have a thorough talk with the anaesthetist — all pre-existing conditions are discussed. Modern general anaesthesia is very safe; serious complications are rare and monitored. You fall asleep and wake up without experiencing the surgery.

"Travelling alone — can I manage after such major surgery?"

A companion is strongly recommended for the first 5 to 7 days in Istanbul, especially for the trips between hospital and hotel. If you travel alone you receive enhanced Mapa support. WhatsApp hotline is reachable 24/7.

"What if I do not speak Turkish?"

Admission, surgical consent and follow-ups are in English. Hospital nurses communicate via Mapa interpreters. Diet plan and medication list are issued in English for your GP at home.

What you actually experience

Small observations after gastric reduction surgery

No marketing phrases. Short, honest observations — what typically feels like after bariatric surgery during the first days, weeks and months.

Day 1–7

Abdominal pain and tightness in the first 48 to 72 hours are normal — well manageable with pain medication.

Day 1–7

Hunger is completely absent in the first weeks — the stomach no longer sends hunger signals.

Day 1–7

Nausea on the first sip can occur — small sips every 15 minutes help.

Day 1–7

Shoulder pain from the CO₂ gas of laparoscopy is common and passes within 2 to 3 days.

Week 1–6

Diet progression: liquid → puree → soft → solid, each 1 to 2 weeks.

Week 1–6

Tiredness and weakness in the first 2 weeks are expected — the body needs energy for healing.

Week 1–6

The first "no-hunger experience" at the dinner table feels surprising for many patients.

Week 1–6

The first 5 to 8 kg are often lost in the first 2 to 3 weeks.

1–6 months

Main weight loss phase — typically 60 to 70 percent of the expected loss in the first 6 months.

1–6 months

Hair loss from month 3 to 6 is common and reversible — sufficient protein and a multivitamin help.

1–6 months

Loose skin becomes increasingly noticeable, especially on the abdomen, arms and thighs.

1–6 months

Physical activity is possible from week 6 — light training first, then strength training from month 3.

6 months–2 years

Plateau phase after 12 to 18 months — the final weight stabilises.

6 months–2 years

Lifelong vitamin substitution (B12, iron, calcium, multivitamin) becomes routine.

6 months–2 years

Social adjustment when eating with friends — small portions become standard.

6 months–2 years

Plastic surgery for loose skin is possible from month 18 to 24, once the weight is stable.

Observations from medical sources and physician-led aftercare — no patient quotes, no success guarantees. Your individual experience may vary depending on procedure, baseline findings and lifestyle.
Honestly answered

What patients often hesitate to ask

Honest answers on gastric sleeve — reflux, permanence, regain, loose skin.

Will I never be able to eat normally again after sleeve surgery?

You will, but differently. After 6-12 months of adjustment, you can typically eat most foods, but in much smaller portions — around 150-200 grams per meal instead of 500 grams. Social eating with friends remains possible, but requires adaptation — order a small portion, eat slowly, chew well. Most patients describe this as "a normal new normal".

How high is the mortality risk with sleeve surgery?

Mortality risk for laparoscopic sleeve in specialised centres: typically 0.1-0.2% (around 1-2 per 1,000 patients). Complication rate 1-3%, usually well manageable (bleeding, staple-line leak). Risk factors: high BMI, comorbidities, prior abdominal surgeries, smoking. Comparison: the risk of dying from obesity-related complications without surgery is several times higher with a BMI over 40.

What about reflux after sleeve surgery?

Heartburn and reflux are more common after sleeve than after bypass — roughly 20-30% of patients develop new or worsened reflux. With pre-existing reflux, sleeve is often not the right choice; bypass may be better. An honest clinic performs a pre-operative endoscopy and assesses reflux risk.

Will my stomach stretch out again after years?

Moderate dilation of the sleeve stomach after 5-10 years is normal — up to around 30%. Most patients experience slight regain of 5-10 kg without returning to their starting weight. Those who do not maintain dietary changes long-term may regain more. With significant stomach dilation, a re-sleeve or conversion to bypass is possible.

What happens to my skin?

Loose skin after 30-50 kg of weight loss is the rule — most pronounced on the abdomen, upper arms, thighs and breasts. Plastic surgeries (abdominoplasty, breast lift, brachioplasty) are typically possible from 18-24 months after sleeve, once weight is stable. These follow-up procedures are substantial interventions with their own costs and risks.

Will I lose hair?

Diffuse hair loss from month 3-6 is common (around 50% of patients) — caused by rapid weight loss and protein deficit. It is usually reversible: hair regrows from month 9-12 once nutrition stabilises. Adequate protein intake (60-80 g per day) and a multivitamin can reduce the severity.

What if I regret it after 2 years?

Sleeve is, in the strict sense, irreversible — the removed portion of stomach cannot be restored. In theory, conversion to a bypass is possible, though technically complex. Regret ("bariatric regret") affects 5-15% of patients in the first 12 months. An honest pre-operative assessment with psychological evaluation reduces the risk.

What documents and tests should I send before my trip?

Send recent diagnostic reports (relevant to your procedure: imaging, blood work, specialist letters), your full medication list including supplements, allergy history, and a brief health summary including chronic conditions and prior surgeries. Our medical team reviews these free of charge within 24-48 hours so we can confirm candidacy, finalize the plan and quote a binding price before you book travel.

Risks & Safety Information

Gastric sleeve surgery (sleeve gastrectomy) permanently reduces stomach capacity by approximately 75–80%. It is the most frequently performed bariatric surgery worldwide, with well-established long-term safety data.

  • Staple line leak — the most significant surgical risk (1–3%), requiring immediate treatment
  • Post-operative nausea and vomiting during dietary transition phase
  • Gastroesophageal reflux (GERD) — may develop or worsen in some patients
  • Nutritional deficiencies requiring lifelong vitamin supplementation (B12, iron, calcium, vitamin D)
  • Stricture (narrowing) of the sleeve requiring endoscopic dilation (2–3%)
  • Gallstone formation due to rapid weight loss (preventable with medication)
  • Rare: blood clots, bleeding, or wound infection
✓ Safety Assurance:

All bariatric procedures are performed laparoscopically using 4–5 small incisions (0.5–1.2 cm). Leak testing is performed intraoperatively using methylene blue dye and/or air insufflation. Patients are monitored for 2–3 nights post-operatively with gradual dietary progression.

Recovery Timeline

Days 1–3 (Hospital)

Clear liquids only. Walking encouraged on day 1 to prevent blood clots. Pain managed with medication. Leak test performed before advancing diet.

Weeks 1–2

Full liquid diet (protein shakes, broth, yogurt drinks). Gradually increase fluid intake. Mild fatigue is normal.

Weeks 3–4

Soft pureed foods introduced. Eat slowly, small portions. Protein intake prioritized (minimum 60g daily).

Weeks 5–8

Soft solid foods introduced gradually. Three small meals per day. Avoid carbonated drinks, sugar, and high-fat foods.

Month 3+

Regular diet with reduced portions. Most patients return to full activities. Rapid weight loss phase (most loss occurs in first 6–12 months).

Who Is a Good Candidate?

Good Candidates

  • Patients with BMI 35+ (or BMI 30+ with obesity-related health conditions)
  • Those who have attempted supervised diet and exercise programs without sustained success
  • Patients committed to long-term lifestyle changes and follow-up care
  • Individuals with obesity-related conditions: type 2 diabetes, sleep apnea, hypertension, joint pain
  • Age 18–65 with acceptable surgical risk

Not Recommended For

  • Patients with untreated eating disorders (binge eating requires psychological support first)
  • Active alcohol or substance abuse
  • Severe, unmanaged psychiatric conditions
  • Medical conditions making general anesthesia too risky
  • Patients unwilling to commit to lifelong dietary and supplement changes
