Bariatrik cerrahi (BC), ağırlık kaybı ve obeziteye dair komorbiditelerin iyileşmesinde önemli bir yöntemdir. BC öncesi ve sonrasında hastanın beslenme durumu diyetisyen tarafından Amerikan Metabolik ve Bariatrik Cerrahi Topluluğu (ASMBS) kılavunzlarına göre ayrıntılı olarak değerlendirilmelidir.
Cerrahi sonrası başarıyı sağlayabilmek adına, cerrahi öncesi ve sonrası uygun enerji ve makro besin ögesi kompozisyonları sağlanmalıdır. Cerrahi öncesi kalori kısıtlaması ile ağırlık kaybının sağlanması ameliyat sürecindeki komplikasyonları azaltarak, iyileşme sürecini de hızlandırmaktadır. Cerrahi öncesi ve sonrasında makro besin öğelerinin kompozisyonu için net bir görüş bulunmamaktadır. Cerrahi sonrası protein alımının en az >60 g olması kas kaybını önlemeye yardımcı olur. Cerrahi sonrası oluşan emilim bozukluğu sebebiyle düşen serum omega-3 (n-3) düzeylerini engellemek için diyette n-3’ten zengin besinlere yer verilebilir, gerekirse n-3 takviyeleri uygulanabilir.

Bariatric surgery (BC) is an important method for weight loss and recovery from obesity-related comorbidities. The nutritional status of the patient before and after BC should be evaluated in detail by a dietician according to the American Society for Metabolic and Bariatric Surgery (ASMBS) guidelines.
In order to ensure success after surgery, appropriate energy and macronutrient compositions should be provided before and after surgery. Weight loss with calorie restriction before surgery, reduces complications during the surgery and accelerates the recovery process. There is no clear view on the composition of macronutrients before and after surgery. A protein intake of at least >60 g after surgery helps prevent muscle loss. In order to prevent serum omega-3 (n-3) levels that decrease due to malabsorption after surgery, foods rich in n-3 can be included in the diet, and n-3 supplements can be applied if it necessary.
