What type of bariatric surgery restricts total intake and limits calories obtained?

Restrictive surgery is characterized by procedures that limit the amount of food the stomach can hold, effectively reducing total caloric intake. This type of surgery typically involves the creation of a smaller stomach pouch that restricts the volume of food consumed at one time, leading to early satiety and reduced appetite.

Procedures such as gastric banding and sleeve gastrectomy are examples of restrictive surgeries. They focus primarily on decreasing the size of the stomach, leading to a feeling of fullness with less food and thus promoting weight loss through reduced caloric intake.

In contrast, malabsorptive surgery involves altering the digestive process to reduce calorie and nutrient absorption, which is not the primary mechanism in restrictive surgery. Combination surgeries incorporate both restrictive and malabsorptive elements, while endoscopic surgery typically refers to minimally invasive techniques not focused solely on restriction.

Understanding the nuances of these types of bariatric procedures is crucial for recognizing their mechanisms and implications in patient management and weight loss outcomes.
