Istanbul / Turkey
Obesity is much more than a cosmetic concern—it is a chronic medical condition that can affect nearly every aspect of life, from mobility and energy levels to serious health conditions such as type 2 diabetes, hypertension, sleep apnea, joint pain, and cardiovascular disease.
As bariatric surgeons with more than 15 years of experience and over 20,000 successful weight loss surgeries, Dr. Tardu and Dr. Ali Katar have dedicated their careers to helping patients regain their health, confidence, and quality of life through advanced laparoscopic bariatric surgery.
Whether you are considering Gastric Sleeve (Sleeve Gastrectomy), Gastric Bypass, or a Revision Bariatric Surgery such as Band to Sleeve or Sleeve to Bypass, our goal is always the same:
To provide the safest surgery with the most comfortable recovery possible.
Choosing the right bariatric surgeon is one of the most important decisions you will ever make.
Our surgical philosophy combines extensive experience with modern surgical techniques designed to reduce discomfort and accelerate recovery.
✅ 15+ years of bariatric surgery experience
✅ More than 20,000 successful procedures
✅ Advanced laparoscopic (keyhole) surgery
✅ Special nerve block technique for enhanced comfort
✅ No routine surgical drains
✅ Early mobilization after surgery
✅ Comprehensive aftercare and nutritional guidance
✅ International patient support
Every patient receives a personalized treatment plan based on their BMI, medical history, previous surgeries, and long-term weight loss goals.
One of the biggest concerns patients have before surgery is:
"Will I experience severe pain, nausea, or vomiting?"
The answer is that we actively work to minimize these symptoms.
Dr. Tardu and Dr. Ali Katar use a special intraoperative nerve block technique designed to significantly improve postoperative comfort.
This advanced pain management approach helps reduce postoperative discomfort and contributes to a smoother recovery experience.
Many of our patients are pleasantly surprised by how comfortable they feel after surgery.
Our recovery protocol is specifically designed to encourage:
Less postoperative pain
Reduced nausea
Reduced vomiting
Faster mobilization
Earlier return to daily activities
Early mobilization is one of the keys to a successful recovery.
Most of our patients begin walking approximately 2 hours after surgery under the supervision of our medical team.
Walking early helps:
Improve circulation
Reduce the risk of blood clots
Support lung function
Speed up overall recovery
Increase patient confidence
Many patients are surprised by how quickly they are able to stand and walk comfortably.
Unlike many bariatric centers, we do not routinely use surgical drains after Gastric Sleeve or Gastric Bypass surgery.
Avoiding drains can make the recovery process more comfortable and allows patients to move more freely during their hospital stay.
Patients typically stay in the hospital for:
3 nights / 4 days
During this time our multidisciplinary team carefully monitors:
Hydration
Pain management
Walking
Nutrition
Recovery progress
Before discharge, patients receive detailed nutritional guidelines and postoperative instructions.
One of the biggest advantages of minimally invasive laparoscopic surgery is the rapid return to normal life.
Most patients:
Return home after 4 days
Can return to office work shortly after discharge
Resume normal daily activities quickly
Feel noticeably more energetic within weeks
The only major restriction is:
We advise patients not to lift heavy objects during the first month after surgery.
Apart from avoiding heavy lifting, patients gradually return to their normal routines.
Weight loss after bariatric surgery is a gradual process.
The most significant weight loss occurs during the first 12 months.
On average, patients lose approximately:
Up to 90% of their excess weight within one year, provided they follow the recommended nutritional and lifestyle guidelines.
Every patient's journey is unique, but the transformation can be life-changing.
Bariatric surgery is not only about losing weight.
It is about improving overall health.
Many obesity-related conditions begin improving as early as the first month after surgery.
Patients frequently report improvements in:
Type 2 Diabetes
High Blood Pressure
Sleep Apnea
Shortness of Breath
Joint Pain
Fatigue
Mobility
Self-esteem
Energy Levels
By the end of the first year, many patients describe themselves as:
Happier
More energetic
More active
More confident
Healthier than they have felt in years
Gastric Sleeve, also called Sleeve Gastrectomy, is one of the most commonly performed bariatric procedures worldwide.
During surgery, approximately 75–80% of the stomach is removed, leaving a smaller, tube-shaped stomach.
Benefits include:
Significant weight loss
Reduced hunger
Smaller meal portions
No intestinal bypass
Excellent long-term outcomes
Gastric Bypass combines stomach reduction with changes to the digestive tract.
It is especially effective for patients with:
Severe obesity
Type 2 Diabetes
Acid reflux (selected cases)
Revision surgery requirements
This procedure helps patients achieve substantial and sustainable weight loss while improving many obesity-related diseases.
Not every previous weight loss surgery provides lasting success.
If you previously underwent bariatric surgery and regained weight or experienced complications, revision surgery may be the appropriate solution.
Our experienced team performs advanced revision procedures including:
Patients with an old gastric band often choose conversion to Gastric Sleeve for improved long-term outcomes and greater comfort.
Patients who experience weight regain, reflux, or insufficient weight loss after Sleeve Gastrectomy may benefit from conversion to Gastric Bypass.
Revision bariatric surgery requires extensive surgical expertise, and our team has significant experience managing these complex procedures safely.
Thanks to our advanced minimally invasive techniques and our special nerve block protocol, most patients report significantly less discomfort than they expected.
Our anesthesia and pain management protocol is specifically designed to reduce postoperative nausea and vomiting. While every patient is different, many experience minimal or no nausea during recovery.
Most patients begin walking approximately 2 hours after surgery.
No. We do not routinely use drains after surgery.
Our standard hospital stay is 3 nights and 4 days.
Many patients return to office-based work after being discharged, depending on the nature of their job and individual recovery. Jobs involving heavy physical activity may require additional recovery time.
We recommend avoiding heavy lifting during the first month after surgery.
Most patients lose the majority of their excess weight during the first year. With good compliance to dietary and lifestyle recommendations, excess weight loss can reach approximately 90%.
Many obesity-related conditions—including type 2 diabetes, hypertension, sleep apnea, and shortness of breath—often begin improving within the first months after surgery. Individual results vary and depend on each patient's overall health and adherence to medical advice.
