Assoc. Prof. Dr. Ozan Şen is a general surgeon whose professional practice has a particular focus on obesity and bariatric surgery. His current clinical interests include advanced laparoscopic techniques, sleeve gastrectomy, gastric balloon treatment, reflux surgery, and medical weight management.

Dr. Şen was born in Isparta in 1977. He graduated from Isparta Anatolian High School in 1995 and entered Ankara University Faculty of Medicine in the same year. After completing six years of medical education, he pursued specialist training in general surgery at Ankara University.

His later professional career became increasingly focused on bariatric and minimally invasive surgery. He has participated in clinical training and observation programs in the United States and Europe.

Dr. Şen currently sees patients in Istanbul. He also continues academic work alongside his clinical practice.

What Is Dr. Ozan Şen's Educational and Professional Background?

Dr. Ozan Şen completed both medical school and general surgery specialist training at Ankara University. He began his general surgery residency in 2002 and completed it in 2008.

After specialization, he completed compulsory public service at Van Regional Training and Research Hospital. This period lasted approximately three years.

He later completed military service as a medical officer. Afterward, he gained additional clinical experience in breast and thyroid surgery before working at a private hospital in the Milas area of Muğla.

Dr. Şen had developed an interest in laparoscopic surgery during residency. In 2013, he moved to Istanbul and began focusing more intensively on bariatric surgery.

He subsequently spent several years working in specialist bariatric surgery teams. His current clinical focus includes obesity surgery, advanced laparoscopy, reflux surgery, and long-term weight management.

What Services Does Dr. Ozan Şen Offer?

Dr. Ozan Şen works with surgical, endoscopic, and medical approaches related to obesity and weight management. Sleeve gastrectomy, bariatric surgery assessment, and gastric balloon treatment are among his main current services. Reflux surgery is another area of his clinical practice.

The same approach is not appropriate for every person seeking weight treatment. Body mass index, obesity-related conditions, previous attempts at weight loss, and general health can influence treatment planning.

A gastric balloon provides an endoscopic option and differs from bariatric surgery. Surgical procedures are generally performed using minimally invasive approaches when clinically appropriate.

Dr. Şen's professional background also includes training in robotic surgery.

Medical weight-management treatments are also included among his current areas of practice. Medication should be selected and monitored according to individual medical needs.

Does Dr. Ozan Şen Perform Sleeve Gastrectomy?

Dr. Ozan Şen performs sleeve gastrectomy as one of the main procedures within his bariatric surgery practice. Sleeve gastrectomy is a surgical weight-management procedure used for selected patients with obesity.

Suitability for surgery is not determined by body weight alone. Body mass index, obesity-related medical conditions, previous weight-management attempts, and overall health all need consideration.

Preoperative evaluation may include laboratory testing and assessment of nutritional and medical factors.

After surgery, patients usually follow a staged dietary program. Long-term nutritional habits are also important.

Vitamin and mineral monitoring may be relevant after bariatric surgery depending on the individual situation. Follow-up is therefore an important part of treatment rather than an optional stage after surgery.

The final decision about surgery requires an individual medical assessment.

Does Dr. Ozan Şen Offer Gastric Balloon Treatment?

Dr. Ozan Şen offers gastric balloon treatment as a non-surgical approach to weight management. The gastric balloon is an endoscopically placed device that can later be removed.

It is not appropriate for every patient with excess weight. Medical history, previous stomach surgery, gastrointestinal symptoms, and overall treatment goals may influence suitability.

The balloon does not replace changes in eating habits. Nutritional planning and follow-up remain important during the treatment period.

Different balloon systems may have different durations and management requirements. These details can be discussed after medical assessment.

Gastric balloon treatment also differs from bariatric surgery. The appropriate approach depends on the degree of obesity, medical conditions, previous treatments, and individual preferences.

What Is Dr. Ozan Şen's Approach to Bariatric Surgery?

Dr. Ozan Şen has a professional background strongly focused on laparoscopic bariatric surgery. He developed an interest in minimally invasive surgery during specialist training and later concentrated on advanced laparoscopic procedures.

His bariatric surgery work became more intensive from 2013 onward. Over the following years, he worked with obesity surgery, advanced laparoscopy, and reflux surgery in specialist clinical settings.

Current treatment planning also includes preoperative evaluation and postoperative monitoring. Nutritional follow-up can form an important part of the process.

Bariatric surgery is not considered a cosmetic operation. The decision is based on medical indications and the potential health impact of obesity.

Patients should therefore undergo individual evaluation before a specific operation is selected.

Has Dr. Ozan Şen Received Robotic Surgery Training?

Dr. Ozan Şen has received robotic surgery training in the United States. In 2017, he participated in a robotic surgery program in Cleveland and received certification in this field.

During the same visit, he also observed bariatric surgery procedures and different minimally invasive approaches.

This training followed an earlier period in New York. In 2015, he visited a bariatric surgery unit there on two separate occasions for clinical observation.

Robotic surgery is not required for every operation. Robotic and conventional laparoscopic techniques have different practical applications.

The most suitable surgical approach depends on the procedure, patient anatomy, clinical circumstances, and surgical assessment.

Robotic and laparoscopic training are both listed within Dr. Şen's current professional profile.

Does Dr. Ozan Şen Perform Reflux Surgery?

Dr. Ozan Şen includes reflux surgery within his general surgery practice. Surgical treatment may be considered for selected patients with gastroesophageal reflux disease after appropriate assessment.

Not every person with reflux symptoms requires surgery. Symptom pattern, previous treatment, and anatomical findings can all affect the decision.

Further tests may sometimes be required before surgery. These can help determine whether symptoms are related to reflux and whether an operation is appropriate.

Patients who have both obesity and reflux may need a broader assessment because body weight and stomach anatomy can influence treatment selection.

Dr. Şen's professional background includes long-term experience with reflux surgery and advanced laparoscopic techniques.

Does Dr. Ozan Şen Have International Surgical Experience?

Dr. Ozan Şen has participated in bariatric and robotic surgery training and observation programs outside Turkey. In 2015, he spent two separate periods at a hospital in New York observing bariatric surgery.

In 2017, he attended robotic surgery training in Cleveland. He also observed bariatric operations during this period.

In 2018, he visited a specialist obesity surgery practice in Belgium and participated in clinical observations there.

These experiences formed part of his continuing professional education in bariatric and minimally invasive surgery.

International training can expose surgeons to different techniques and treatment protocols. However, the final treatment plan for an individual patient still depends on personal medical findings.

Does Dr. Ozan Şen Have an Academic Career?

Dr. Ozan Şen continues academic work alongside his clinical practice. Current professional information lists him as a faculty member at Istanbul Nişantaşı University Faculty of Medicine.

The university's 2025-2026 general surgery training schedule lists him as a lecturer on obesity, gastrointestinal disorders, and other general surgery topics.

His academic record includes international publications related to bariatric surgery. Current professional information also lists academic citation metrics associated with his research work.

Dr. Şen is also a member of international professional organizations related to bariatric and metabolic surgery. These academic and professional activities complement his clinical work.

What Happens During the First Consultation with Dr. Ozan Şen?

The first consultation with Dr. Ozan Şen focuses on the patient's weight history, medical background, previous treatments, and reason for seeking care.

For bariatric surgery, body mass index is only one part of the assessment. Conditions such as diabetes, hypertension, sleep-related problems, and reflux may also be relevant.

Previous abdominal or stomach surgery should be discussed. Patients should also provide an updated medication list and information about chronic medical conditions.

After assessment, surgical, endoscopic, or medical weight-management options may be discussed.

The final approach depends on medical suitability and the patient's individual circumstances.

For patients proceeding with bariatric surgery, postoperative nutritional planning and long-term follow-up are also important parts of treatment.

Where Is Dr. Ozan Şen's Clinic Located?

Dr. Ozan Şen's current practice is located in the Fulya area of Şişli, Istanbul. The listed address is Fulya Mahallesi, Yeşilçimen Sokak No:12, Polat Tower Residence, Unit 438, Fulya Academy, Şişli, Istanbul.

Fulya is centrally located on the European side of Istanbul and is close to Şişli and Beşiktaş.

Some older online listings show another nearby building number. His current contact information lists the Polat Tower Residence address.

Patients travelling from another city or country should consider that bariatric surgery may require several postoperative reviews.

First-time visitors may wish to confirm the current address and appointment time before travelling.

How Can You Book an Appointment with Dr. Ozan Şen?

Patients can request an appointment with Dr. Ozan Şen through the current contact channels of his practice. Telephone, WhatsApp, and an online contact form are available.

Mentioning the reason for consultation can help with scheduling. Sleeve gastrectomy, gastric balloon treatment, reflux surgery, and general obesity assessment may require different types of evaluation.

Patients who have previously undergone bariatric or abdominal surgery should provide this information when arranging the consultation.

Existing medical reports, laboratory results, and an updated medication list may also be useful.

A surgical procedure is not confirmed solely through an appointment request. Medical suitability should first be assessed.

Treatment options, preparation, and follow-up can then be planned according to the patient's individual findings.
