Obesity is not a matter of willpower. It is a treatable disease.
No single method suits everyone. The right decision comes from assessing body mass index, related conditions and eating habits together.

Which method, for whom?
Methods that create a permanent anatomical change. Considered at a BMI of 40 or above, at 35-40 with a related condition, or above 30 with type 2 diabetes or severe metabolic problems.
Endoscopic examination of the stomach and large bowel, used to investigate symptoms and, if needed, as part of the assessment before surgery.
Laparoscopic procedures beyond obesity surgery. Reflux and hernia surgery have long been focus areas of Prof. Dr. Ersoy.
From the first consultation to the 6-month check
Decision, tests and follow-up: every step is explained in advance.
-
Initial consultation
Day oneThe first consultation covers your weight history, methods you have tried, related conditions and your expectations. By the end it is clear whether surgery is on the table and, if so, which methods will be discussed. No decision is made at this stage. Test results come first.
- Weight history
- Methods tried
- Expectations and concerns
-
Tests and preparation
1-3 weeksBlood tests are performed, and an endoscopy if needed. Where needed, cardiology, pulmonology, endocrinology, dietitian and psychiatric assessments are requested. Alcohol and smoking are stopped before surgery. The aim is not only to confirm fitness for surgery but also to start preparing for the post-operative diet.
- Blood tests
- Endoscopy if needed

Surgery and hospital stay
2-4 days in hospitalThe method, length of stay and diet in the first days are explained in detail before surgery. With laparoscopic methods the stay is usually a few days. At discharge you receive written guidance on which symptoms require an immediate call.
- Laparoscopic procedure
- Liquid diet on day one
- Written discharge instructions
-
Follow-up
At 6 monthsThe routine check is a blood test at 6 months. It monitors vitamin and protein levels, and new eating and activity habits are followed during this period. This phase largely determines the outcome. Surgery alone does not produce a lasting result.

Choose a topic, answer a few short questions if you like, and we will contact you by your preferred channel.
Can I choose the method myself?
The choice of method is based on examination and test results, not on preference. It rests with the physician. The consultation explains in detail why a particular method is recommended.
When can I return to work?
With laparoscopic methods the hospital stay is a few days. Most patients can return to a desk job within 10-15 days; physically demanding work takes longer.
Will I regain weight?
Surgery alone does not produce a lasting result. Returning to old eating habits leads to weight regain, which is why follow-up, including a routine blood test at 6 months, is an integral part of the process.
I have heart disease. Can I have surgery?
Heart disease on its own is not a barrier. A cardiology assessment is carried out before surgery and the risk is weighed together.
I live abroad. How does the process work?
You can send your test results and request an information call; this call does not replace an examination. Examination and treatment take place at Medistate Kavacık Hospital in Istanbul; arrival date, length of stay and follow-up after your return are planned in advance.
