What is bariatric surgery?
Bariatric surgery is aimed to modify the digestive system in severely obese patients and it is an important therapeutic option if dietary and behavioral remedies have failed in reducing the patient’s body weight.
Bariatric surgery can be:
- Restrictive surgery: food intake is restricted by creating a small pouch at the top of the stomach where the food enters from the esophagus. It based on the individual’s gastric capacity and on a rapid attainment of a feeling of satiety,
- Malabsorption operations: it consists in the installation of an intestinal by-pass which limits the absorption of the calories the individual introduces into his/her organism.
Nowadays, bariatric surgery based on mixed techniques is more and more common: these techniques pair a restrictive intervention on the stomach with an intestinal by-pass. This system is recommended in severely obese patients or in patients on whom restrictive interventions are not recommended.
After surgery it's important to follow the nutritional pattern recommended by your physician. In the first days after surgery the patient feeds through a liquid and semi-liquid diet (milk, broth with meat baby food, yogurt); returning to a solid nutrition happens gradually within a month and a half to two months. Meals must be consumed slowly and food must be chewed sufficiently. Furthermore it is important to integrate one's diet with vitamin-mineral food supplements in order to avoid the lack of these important elements.
