Restrictive weight loss surgery procedures
The theory is simple. When you feel full, you are more likely to have reduced feelings of hunger and will no longer feel deprived. The result is that you are likely to eat less. Restrictive weight loss surgery works by reducing the amount of food consumed at one time. It does not, however, interfere with the normal absorption (digestion) of food. In a restrictive weight loss procedure, such as one using the Swedish Adjustable Gastric Banding (SAGB), the surgeon creates a smaller upper stomach pouch. The pouch, with a capacity of approximately 15 to 30 ml, connects to the rest of the stomach through a small adjustable outlet. In a cooperative and compliant patient, the reduced stomach capacity, along with behavioral changes, can result in consistently lower caloric intake and consistent weight loss.
During recovery from a restrictive procedure, patients must adhere to the specific dietary guidelines and restrictions their bariatric surgeon prescribes. While these guidelines may vary from one surgeon to the next, and will be tailored to each patient, it is important for each patient to follow the surgeon's guidelines.
If the patient fails to follow these guidelines, they can stretch the stomach pouch and/or cause slippage of the band and defeat the purpose of the surgery. The effectiveness of a restrictive procedure is reduced by constant snacking or by drinking high-calorie, high-fat liquids. Failure to achieve the expected level of weight loss may be the result of a patient failing to comply with the recommended dietary and behavior modifications, such as increased exercise and regular support group attendance.
