What is Obesity Surgery?

Obesity surgery, also called weight loss surgery or bariatric surgery, can help to achieve significant weight loss and resolve obesity-related health problems. Type 2 diabetes, sleep apnea or hypertension can be examples of these problems. There are various surgical options based on patients’ needs and health conditions. Operations either restrict the amount of food consumed or reduce the ability to absorb nutrients. A combination of both is also possible for several cases. Surgery for weight loss can be a life-saving option for people with severe obesity. It is also a major procedure that poses certain risks and side effects. At ACIBADEM Beauty Center, we perform an extensive evaluation with a multidisciplinary team of experts before a bariatric surgery. It ensures that each patient receives the medical procedure that is right for him.

Weight loss surgery has been refined to improve results and reduce risks during recent years. ACIBADEM patients can benefit from the robotic surgery option. Robotic obesity surgery is associated with lower risk of complications during post-operation period. The procedure is performed with the “da Vinci” system which is called ‘robot-assisted laparoscopic surgery’. Robotic obesity procedures have reduced the blood loss, risk of infection, scars and recovery times.

After your surgery, you’ll be given a detailed dietary plan to follow. In general, you will be on liquid diet first few days; pureed food first few weeks, and soft food for another couple of weeks before returning to a regular healthy diet. It is important to eat balanced meals with restricted portions, four to six times a day, and this is a lifetime recommendation for obesity surgery patients.

Every patient is different and recovery time varies. However, most patients return to their daily activities, including work, in 1-4 weeks, depending on the type of procedure. After bariatric surgery, you should avoid lifting and activities that might affect the abdominal region until your doctor allows it.
