Gastric Sleeve vs Gastric Bypass: Which Is Better for Long-Term Weight Loss?

A clear comparison of the two most common bariatric procedures — how each works, the risks, dietary changes and which patients are best suited for each.

What You Need to Know

Medical tourism in Istanbul has grown significantly over the past decade, with thousands of international patients choosing Turkey for high-quality treatments at competitive prices. Understanding your options thoroughly before committing to any procedure is essential.

"The most important step is choosing a clinic that prioritises your safety and long-term results over short-term profits."

Key Considerations

Before travelling to Istanbul for medical treatment, there are several important factors to evaluate carefully:

  • Clinic accreditation status — look for JCI or international equivalents
  • Surgeon board certification and years of experience
  • Before and after portfolio — request specific case photos
  • Clear communication in your language
  • Post-operative support and follow-up protocols
  • Transparent, all-inclusive pricing with no hidden costs

The Treatment Process

Once you've selected a clinic, the process typically begins with a digital consultation. Your medical history is reviewed, candidacy is assessed, and a personalised treatment plan is proposed. Travel arrangements, accommodation and clinic appointments are then coordinated by your patient coordinator.

During Your Stay

Most patients stay between 3–10 days depending on the procedure. Your coordinator handles transfers between your hotel and the clinic, and is available throughout your stay for any questions or concerns.

Recovery and Aftercare

Recovery protocols vary by procedure, but all Medical Center Klinik patients receive comprehensive aftercare documentation and direct access to their medical team via WhatsApp for follow-up questions after returning home.
