Final answer:
The correct answer to the type of bariatric surgery that is restrictive is c) Adjustable gastric banding.
Step-by-step explanation:
Restrictive bariatric surgeries are designed to reduce the size of the stomach and limit food intake without altering the absorption of nutrients. Adjustable gastric banding involves placing an inflatable band around the upper portion of the stomach, creating a small stomach pouch above the band, and a narrow opening to the rest of the stomach. This band can be adjusted to change the size of the opening and control the amount of food that can be consumed.
Types of bariatric surgery include:
- Gastric bypass (Roux-en-Y) - a combination surgery that both restricts the stomach size and alters digestion, leading to reduced calorie absorption.
- Biliopancreatic diversion - mostly malabsorptive, it also reduces the stomach size but with more significant bypass of the small intestine.
- Adjustable gastric banding - purely restrictive, it reduces food intake by creating a small pouch at the top of the stomach.
- Duodenal switch - a combination surgery that is primarily malabsorptive but also reduces stomach size.
People who qualify for bariatric surgery are typically those who have a body mass index (BMI) of 40 or higher or have a BMI of 35 with serious health problems related to obesity. The main goal of bariatric surgery is to help with weight loss when other methods such as diet and exercise have not been successful.
