Restrictive & MalabsorptiveRestrictive Procedures The theory of restrictive procedures goes as follows: when you feel full, you are more likely to have reduced feelings of hunger and will no longer feel like you are being deprived of food. The result is that you are likely to eat less. Restrictive procedures in 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, the surgeon creates a smaller upper stomach pouch. The pouch, with a capacity of approximately 1/2 to 1 oz. (15 to 30 ml), connects to the rest of the stomach through an outlet known as a "stoma." 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. 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 is usually the result of a patient failing to follow the recommended diet and behavior modifications after the operation, and to participate in increased exercise and regular support group attendance. Malabsorptive Procedures that Alter Digestion Weight loss procedures that alter digestion,
are known as malabsorptive procedures. They
were developed to work in conjunction with restrictive approaches to
encourage even greater weight loss. Some of these techniques involve
a bypass of the small intestine, which limits the absorption of calories.
Malabsorptive or malabsorptive/restrictive procedures have resulted
in an overall increase in the loss of excess weight in patients. The
risk of complications and side effects generally increases with the
lengthening of the small intestine bypass. The bariatric surgeon
and patient must determine the risks and benefits over the patients
lifetime with the type of weight loss surgery chosen. Related Links Surgical Weight Loss |
