Operative treatment of obesity - what diet before surgery?
- | 19.08.2021 | 5 minutes
There are many reasons why dietary preparation for bariatric surgery is essential. A proper diet before surgery will help with weight reduction, which consequently reduces the risk of potential complications during as well as after surgery. Importantly, an important part of preparing for surgery is shrinking the liver and reducing abdominal fat, which is achieved with proper dietary recommendations.

What is the dietary preparation for bariatric surgery?


Dietary preparation for bariatric surgery (sleeve gastrectomy, gastric bypass, mini gastric bypass) begins a minimum of 2 weeks before the scheduled surgery date and is an integral part of the surgical treatment of obesity.


Najczęstsze powody przejścia na dietę przed operacją bariatryczną


Istnieje wiele powodów, dla których przygotowanie dietetyczne do operacji bariatrycznej jest niezbędne. Właściwa dieta przed operacją pomoże w redukcji masy ciała, co w konsekwencji zmniejsza ryzyko ewentualnych powikłań w trakcie, jak i po zabiegu. Co istotne, ważnym elementem przygotowania do operacji jest obkurczenie wątroby i zmniejszenie ilości tkanki tłuszczowej w jamie brzusznej, co osiąga się stosując odpowiednie zalecenia żywieniowe.

Wprowadzenie i realizowanie planu żywieniowego przed zabiegiem z całą pewnością ułatwi kontynuacje zdobytych zdrowych nawyków żywieniowych - regularność spożywania posiłków czy właściwe nawadnianie – po operacji. Chirurgiczne leczenie otyłości to droga, w trakcie której następuje zmiana stylu życia. Dzięki zastosowaniu planu żywieniowego przed operacją, wyzwania, z którymi trzeba zmierzyć się po zabiegu są znacznie prostsze i łatwiejsze do pokonania.


How to follow the dietary guidelines before bariatric surgery?


The model of nutrition before surgery is a high-protein, low-calorie diet, with a limited supply of carbohydrates. Protein plays an extremely important role already in the process of preparation for surgery - it speeds up metabolism, protects muscle mass.  It is, among others, thanks to an adequate supply of protein that the body is properly prepared for surgery and the postoperative recovery period. Despite the many benefits of a preoperative diet, for many people its implementation can be a challenge.
