1. Understanding What Is Bariatric Surgery

Bariatric surgery, also known as metabolic surgery, encompasses a range of surgical procedures designed to aid weight loss and improve metabolic health in individuals with obesity. These operations modify the stomach and intestines, leading to reduced food intake and altered nutrient absorption.

1.1. Definition of Bariatric Surgery

Bariatric surgery involves surgical alterations to the digestive system to help individuals lose weight and manage obesity-related conditions. These procedures can reduce the size of the stomach, bypass portions of the small intestine, or both.

1.2. Types of Bariatric Surgery

Several types of bariatric surgery are commonly performed, each with its own advantages and disadvantages:

Sleeve Gastrectomy: Removal of approximately 80% of the stomach, leaving a banana-shaped pouch.
Roux-en-Y Gastric Bypass (RYGB): Creating a small stomach pouch and connecting it directly to the small intestine, bypassing a portion of the stomach and small intestine.
Adjustable Gastric Band (AGB): Placing a silicone band around the upper part of the stomach to restrict food intake.
Biliopancreatic Diversion with Duodenal Switch (BPD/DS): Combining a sleeve gastrectomy with intestinal bypass to reduce calorie and nutrient absorption.
Single Anastomosis Duodeno-Ileal Bypass with Sleeve Gastrectomy (SADI-S): A variation of the BPD/DS with a single connection between the duodenum and ileum.

1.3. How Bariatric Surgery Works

Bariatric surgery works through several mechanisms:

Reduced Stomach Size: Procedures like sleeve gastrectomy and gastric bypass reduce the size of the stomach, limiting the amount of food that can be consumed.
Altered Nutrient Absorption: Procedures like gastric bypass and BPD/DS bypass portions of the small intestine, reducing the absorption of calories and nutrients.
Hormonal Changes: Bariatric surgery can affect gut hormones, reducing hunger, increasing fullness, and improving blood sugar control.

Understanding what is bariatric surgery involves recognizing these key aspects of how these procedures function to promote weight loss and improve metabolic health.

4. Different Types of What Is Bariatric Surgery Procedures

There are several types of bariatric surgery procedures, each with its own unique approach to weight loss and metabolic improvement.

4.1. Sleeve Gastrectomy

Sleeve gastrectomy involves removing approximately 80% of the stomach, leaving a smaller, banana-shaped stomach pouch. This reduces the amount of food a person can eat and also decreases the production of the hunger hormone ghrelin.

Procedure: The stomach is freed from surrounding organs, and surgical staplers are used to remove a large portion of the stomach.
How It Works: The smaller stomach pouch restricts food intake, and reduced ghrelin levels decrease hunger and increase feelings of fullness.
Advantages: Technically simple, shorter surgery time, can be performed in high-risk patients.
Disadvantages: Non-reversible, may worsen or cause new onset reflux and heartburn, less impact on metabolism compared to bypass procedures.

4.2. Roux-en-Y Gastric Bypass (RYGB)

Roux-en-Y gastric bypass involves creating a small stomach pouch and connecting it directly to the small intestine, bypassing a portion of the stomach and small intestine.

Procedure: The stomach is divided into a small pouch, and the small intestine is connected to the pouch, bypassing the larger part of the stomach.
How It Works: The smaller stomach pouch restricts food intake, and bypassing a portion of the small intestine reduces calorie absorption.
Advantages: Reliable and long-lasting weight loss, effective for remission of obesity-associated conditions, refined technique.
Disadvantages: Technically more complex, more vitamin and mineral deficiencies, risk of small bowel complications.

4.3. Adjustable Gastric Band (AGB)

Adjustable gastric band involves placing a silicone band around the upper part of the stomach to restrict food intake. The band can be adjusted by injecting or removing fluid through a port placed under the skin.

Procedure: A band is placed around the top part of the stomach, creating a small pouch above the band.
How It Works: The band restricts food intake by creating a smaller opening between the pouch and the rest of the stomach.
Advantages: Lowest rate of complications early after surgery, no division of the stomach or intestines, band can be removed if needed.
Disadvantages: Slower and less weight loss, risk of band movement or damage to the stomach, requires a foreign implant.

4.4. Biliopancreatic Diversion with Duodenal Switch (BPD/DS)

Biliopancreatic diversion with duodenal switch combines a sleeve gastrectomy with intestinal bypass to reduce calorie and nutrient absorption.

Procedure: A sleeve gastrectomy is performed, and the first portion of the small intestine is separated from the stomach. A part of the small intestine is then connected to the outlet of the newly created stomach.
How It Works: The smaller stomach restricts food intake, and bypassing a significant portion of the small intestine reduces calorie and nutrient absorption.
Advantages: Among the best results for improving obesity, affects bowel hormones to cause less hunger and more fullness, effective for treating type 2 diabetes.
Disadvantages: Higher complication rates, highest malabsorption and greater possibility of vitamin deficiencies, risk of looser bowel movements.

4.5. Single Anastomosis Duodeno-Ileal Bypass with Sleeve Gastrectomy (SADI-S)

Single anastomosis duodeno-ileal bypass with sleeve gastrectomy is a variation of the BPD/DS with a single connection between the duodenum and ileum.

Procedure: A sleeve gastrectomy is performed, and the first part of the small intestine is divided just after the stomach. A loop of intestine is then connected to the stomach.
How It Works: The smaller stomach restricts food intake, and bypassing a portion of the small intestine reduces calorie absorption.
Advantages: Highly effective for long-term weight loss and remission of type 2 diabetes, simpler and faster to perform than gastric bypass or BPD/DS.
Disadvantages: Vitamins and minerals are not absorbed as well as in the sleeve gastrectomy or gastric band, potential to worsen or develop new-onset reflux.

Understanding what is bariatric surgery involves comparing these different procedures, each with its own set of benefits and risks, to determine the most appropriate option for each individual.
