Bariatric surgery refers to a group of surgical procedures performed on individuals who are severely overweight or obese to aid in weight loss and improve overall health. The primary goal of bariatric surgery is to reduce the size of the stomach and/or modify the digestive system to restrict food intake or alter the body’s ability to absorb nutrients.


There are several types of bariatric surgery, including

Gastric Sleeve Surgery (Sleeve Gastrectomy): This procedure involves removing a large portion of the stomach, leaving behind a smaller, banana-shaped stomach pouch. It restricts the amount of food that can be eaten and reduces the production of hunger-inducing hormones.

Gastric Bypass Surgery: This surgery involves creating a smaller stomach pouch by stapling a section of the stomach. Then, a section of the small intestine is connected to the pouch, bypassing a portion of the digestive tract. It restricts food intake and alters the digestion and absorption of nutrients.

Duodenal Switch Surgery: This procedure combines a sleeve gastrectomy with a significant intestinal bypass. It restricts food intake and significantly reduces the absorption of calories and nutrients.

Adjustable Gastric Banding: In this surgery, an adjustable band is placed around the upper part of the stomach, creating a small pouch. The band can be tightened or loosened to control the amount of food that can be consumed.

Bariatric surgery is typically recommended for individuals who have a body mass index (BMI) of 40 or higher (or a BMI of 35-39.9 with obesity-related health conditions) and have been unsuccessful in achieving weight loss through non-surgical methods such as diet and exercise.

Bariatric surgery offers significant and sustained weight loss, leading to improvements in obesity-related conditions like type 2 diabetes, high blood pressure, sleep apnea, and joint pain. However, it is important to note that bariatric surgery is not a quick fix or a stand-alone solution. It requires lifelong commitment to dietary changes, regular physical activity, and follow-up care to ensure long-term success and minimize potential risks and complications.

What Is The Complications In Bariatric Surgery?

Bariatric surgery, like any surgical procedure, carries potential risks and complications. While the majority of individuals who undergo bariatric surgery experience successful outcomes, it’s important to be aware of the potential complications that can occur. These may include:

Infection: There is a risk of developing an infection at the site of the incision or in the abdominal cavity. Proper surgical techniques, sterile conditions, and antibiotic prophylaxis are employed to minimize this risk.

Bleeding: Excessive bleeding during or after surgery is possible. Surgeons take precautions to control bleeding during the procedure, but there is still a small risk of post-operative bleeding that may require intervention.

Blood Clots: Bariatric surgery increases the risk of blood clots forming in the legs (deep vein thrombosis) or traveling to the lungs (pulmonary embolism). Measures such as early mobilization, compression stockings, and blood-thinning medications are used to minimize this risk.

Leaks: After certain types of bariatric surgery, such as gastric bypass or sleeve gastrectomy, there is a small risk of leaks occurring at the staple lines or surgical connections. This can lead to infection or other complications and may require additional surgery to repair.

Strictures: Narrowing of the stomach or the connection between the stomach and intestines can occur, causing difficulty in swallowing or obstructing the passage of food. This may require endoscopic procedures or surgical intervention to correct.

Dumping Syndrome: Dumping syndrome can occur after gastric bypass surgery when food moves too quickly from the stomach to the small intestine. Symptoms may include nausea, vomiting, diarrhea, lightheadedness, and sweating after eating certain foods high in sugar or fat.

Nutritional Deficiencies: Bariatric surgery can affect nutrient absorption, leading to potential deficiencies in vitamins (such as B12, D, and folate), minerals (such as iron and calcium), and protein. Lifelong supplementation and regular monitoring of nutritional levels are necessary to prevent deficiencies.

It’s important to remember that the risks and complications associated with bariatric surgery vary depending on the specific procedure performed and the individual’s overall health. Prior to undergoing surgery, thorough discussions with the healthcare team, including the surgeon and bariatric specialists, can help address concerns, outline potential risks, and provide guidance for a safe and successful surgical experience.

Assoc Dr. Umut Rıza Gündüz

After completing a challenging educational process at Cerrahpaşa Medical Faculty and starting my General Surgery Assistantship at Okmeydanı Training and Research Hospital in 2005, I became a General Surgery Specialist in 2010. Throughout my assistantship in general surgery, I participated in numerous surgeries and performed a great number of operations. My interest and passion for laparoscopic surgery developed during my assistantship.

During my over 10-year tenure at Antalya Training and Research Hospital, I mainly focused on cancer and obesity surgeries. I aimed to perform more laparoscopic surgeries. Additionally, I received domestic and international training in obesity surgery, robotic surgery, and advanced endoscopic procedures. My fascination with technology increased my enjoyment of robotic surgery, laparoscopic surgery, and advanced endoscopic applications.

My curiosity about medical literature gradually led me from reading scientific articles to the stage of writing them. Together with my colleagues and fellow resident doctors, I have contributed to numerous medical articles. By writing and contributing to medical articles, I successfully passed the first stage of my Associate Professorship application and obtained the title of Associate Professor in November 2017.

As a clinical training instructor, I have performed numerous specialized surgeries and had the opportunity to contribute to the education of my fellow resident doctors. In August 2021, due to personal reasons, I had to leave Antalya Training and Research Hospital where I worked with pleasure. In the same year, I started working at Özel Termessos Hospital. While primarily focusing on obesity and metabolic surgeries, I also continue to perform oncological surgeries. Professionally, it makes me happy to enhance my interest in laparoscopic surgery in the field of obesity and metabolic surgery.

With the support of the management at Özel Termessos Hospital, we have made significant progress in health tourism within a year. I am grateful to the management of Özel Termessos Hospital and all its employees for this. As of September 2022, I was honored with a position on the Board of Directors and became a Manager at Özel Termessos Hospital where I have been working. Although I have moved to my private clinic, I continue to perform my surgeries at Özel Termessos Hospital.
