Meet Our Experienced Surgeon, Op. Dr. Osman Aktaş

I am General Surgeon Op. Dr. Osman Aktaş.

I work as a general surgeon at the International Istanbul Avicenna Hospital.

Since 1995, I have been particularly focused on video laparoscopic and endoscopic surgery.

I received advanced training in laparoscopic surgical techniques in Germany.

With laparoscopic methods, I perform surgeries for gallbladder, abdominal wall and inguinal hernias, appendicitis, stomach and reflux surgeries, stomach and intestinal tumors, intestinal obstruction, and other intestinal inflammatory diseases.

In the treatment of obesity (overweight) and diabetes, I apply bariatric and metabolic surgical techniques using laparoscopic methods. This allows patients to permanently get rid of both excess weight and diabetes.

Healthy and Happy Patients

"I discovered which treatment to pursue for my weight through this site and then started treatment with the doctor I chose. My weight loss journey has been closely monitored, and I’ve already lost nearly 80% of the weight I aimed to lose."

İlayda K.

"I didn’t have a lot of weight to lose, but the excess was bothering me. Thanks to this site, I met my doctor and started a nutrition and exercise program that was suitable for me. I was able to have video calls with my doctor whenever I needed and receive motivation. I truly appreciate this."

Deniz P.

"I used to avoid going to the hospital for check-ups. But I’m so glad this site was created. Thanks to it, I was able to diagnose my condition and consult with a doctor. Before things got more serious, I had a gastric balloon surgery. It’s been 4 months since the surgery, and every day I love my body more and more."

Frequently Asked Questions Obesity Surgeries

Everything You Need to Know About Obesity Surgeries Before and After!

How long does it take to recover from gastric sleeve surgery?

The internal stitches in the stomach usually heal within 15 days. The full recovery process takes about 1 month.

How much should you weigh to have a gastric sleeve surgery?

Individuals with severe obesity, a body mass index (BMI) between 35-40, and conditions such as hypertension, sleep apnea, and type 2 diabetes related to obesity are eligible for this surgery.

What age range is gastric bypass surgery performed?

Gastric bypass surgery can be performed on individuals aged 18-65, provided they meet the surgical criteria.

What Should Be Done Before Gastric Sleeve Surgery?

Alcohol and smoking should be discontinued 2 weeks before surgery. Additionally, blood-thinning medications should not be taken. If the patient follows these conditions, they will be admitted to the hospital the day before the surgery, and the operation will take place the following day.

How Should Nutrition Be After Obesity Surgery?

Post-surgery nutrition is carefully explained to the patient by a bariatric dietitian. The process is also monitored at regular intervals by the bariatric dietitian.

What Are the Necessary Follow-ups After Obesity Surgery?

The most crucial period is after the surgery. To achieve the desired weight loss, the doctor will monitor the patient at regular intervals. In the post-surgery period, especially during the first year, the patient should come for check-ups at 1, 3, and 6 months. In the first and second years, check-ups every 6 months are necessary, and from the third year onwards, annual check-ups are sufficient.
