Gastric Sleeve (Vertical Sleeve Gastrectomy)

The gastric sleeve, also known as vertical sleeve gastrectomy (VSG), is a type of bariatric surgery where the bariatric surgeon removes a portion of the stomach, leaving a sleeve-shaped stomach that is about 20% of its original size. Gastric sleeve surgery achieves weight loss by reducing the amount of food that can be consumed as well as the amount of “hunger” hormones produced by the stomach.

Roux-en-Y Gastric Bypass (RNY)

The Roux-en-Y gastric bypass surgery (RNY) is a type of weight loss surgery where the bariatric surgeon divides the stomach and connects it to the small intestine. It differs from gastric sleeve surgery in that weight loss is achieved not just by limiting the size of the stomach, but by allowing food to bypass a portion of the stomach and part of the small intestine, resulting in reduced intake of calories.

One Anastomosis Gastric Bypass (OAGB-MGB)

A one anastomosis gastric bypass surgery (OAGB-MGB) is a simpler, shorter and less invasive version of the traditional Roux-en-Y gastric bypass surgery. During a mini gastric bypass surgery, the bariatric surgeon follows a similar process to a regular Roux-en-y gastric bypass surgery with the main difference being a shorter length of connection to the intestines (Roux limb), the ability to perform the procedure laparoscopically (less invasive) and shorter surgical time.

SADI-S

The SADI-S is a surgery for weight loss that combines the components of the gastric sleeve surgery and duodenal switch surgery, and can provide greater weight loss and metabolic improvements. It can be a good choice for individuals with higher BMIs and who have had previous bariatric procedures but failed to maintain their weight loss goals.

Endoscopic Sleeve Gastroplasty (ESG)

Endoscopic sleeve gastroplasty (ESG) is a minimally invasive non-surgical weight loss procedure that involves using an endoscope inserted through the mouth to reduce the size of the stomach without surgery. The reduction in stomach volume is attained by folding and suturing the stomach instead of removing a portion of it.

TESTIMONIAL

Patient Experience

"Hello everyone, my name is Mustafa Can. On 18.03.2019 I had gastric sleeve surgery. I went from 108 kg down to 71 kg and, thank God, my health is good. I was so satisfied that my sister also had gastric sleeve surgery with Dr. Tuna. I strongly recommend Dr. Tuna Bilecik to anyone struggling with excess weight. Happiness cannot be explained, it must be lived. We love Dr. Tuna."

Mustafa Can (Turkey)

"They are an amazing team — from the bottom to the top. Your valuable doctor, his assistant Ms. Şirin, the nurses, and the room staff all provided excellent service. I feel it is my duty to thank them. We should not forget the dietitian either. If I could, I would build statues of all of them in the hospital garden. My respects to each of them."

Mehmet Karadağ (Turkey)

"I had my surgery with the amazing Dr. Tuna in March & I have never looked back. I was so scared but as soon as I met Dr. Tuna, everything went away. He reassured me in a way I didn’t think was possible. Everything was so professional from start to finish, and he still stays in touch! Even months later, I send him updates and he replies within an hour. Dr. Tuna is definitely your surgeon — you’ll be in the best hands ❤️"

Bethany Hayes (UK)

"There are plenty of bariatric surgeons who will do the job, but then there is Dr. Tuna. He is a Master Surgeon in Bariatrics who genuinely cares about each and every patient, even post-surgery. His investment in patients extends into his carefully trained team, a state-of-the-art hospital, and a comprehensive aftercare package. If you want someone reliable, experienced, genuine and extremely skilled — add Dr. Tuna to your list. I am a former patient and have not been paid to write this."

Rose Openshaw (UK)

"Wonderful team. I am so pleased with the service I received with Dr. Tuna and his team. We were treated like royalty — the best care ever, I felt at home. Dr. Tuna and his team were always available whenever I called. I would recommend Dr. Tuna and his team anytime, any day for your elective surgery. Thank you Doc for taking care of me and my daughter 🙏🏾"

FAQ

What is Weight Loss Surgery?

Weight loss surgery, also known as bariatric surgery, refers to a range of procedures designed to help individuals lose weight and improve their overall health. Two of the most common types of weight loss surgeries include gastric sleeve and gastric bypass. These surgeries work by reducing the size of the stomach, altering the digestive process, or a combination of both.

Each procedure has its own benefits and risks, and the choice of surgery depends on factors such as your overall health, body mass index (BMI), and personal goals. It’s crucial to consult with a qualified bariatric surgeon to determine the most suitable option for your specific circumstances.

To qualify for weight loss surgery, certain criteria must be met. Generally, you would have a BMI that is in the unhealthy range, and possibly health-related conditions such as diabetes, hypertension, or sleep apnea. See if you pre-qualify by using our BMI calculator online.

Before undergoing weight loss surgery, you’ll undergo thorough medical evaluations and pre-surgical assessments. These evaluations help determine your overall health and assess any risks. Our bariatric surgeon and team will guide you through the qualification process and provide the necessary support and information.

Here are the basic steps you will take if you decide to have weight loss surgery. Please remember you are assigned a coordinator and have multiple people along the way guiding you. This is just a basic breakdown of the steps for your big-picture understanding of what to expect:

One of the main reasons people consider weight loss surgery in Turkey is the significant cost savings compared to countries like the United States and European Countries. The cost of weight loss surgery in Turkey can be up to 60% less than the prices in these countries. This affordability factor, coupled with the high-quality healthcare services provided by accredited Turkey bariatric clinics and experienced surgeons, makes Turkey an attractive option for many.

Turkey is known for its well-established medical tourism industry, with numerous facilities, such as our center, catering specifically to international patients seeking weight loss surgery with English-speaking medical staff.
