Bariatric

The field of bariatrics focuses on and treats those who have obesity to promote weight loss and increase overall health with diet, exercise, and behavior therapy.

What is weight loss surgery?

Weight loss surgery, also known as bariatric surgery, is a medical procedure performed to help individuals with severe obesity lose weight. It involves making changes to the digestive system to restrict food intake or alter the body's ability to absorb nutrients, resulting in weight loss.

There are different types of weight loss surgeries, including:

Gastric Bypass: This procedure involves creating a small stomach pouch and rerouting the small intestine to connect to the pouch. This reduces the amount of food the stomach can hold and limits the absorption of calories and nutrients.

Sleeve Gastrectomy: In this surgery, a large portion of the stomach is removed, leaving behind a smaller sleeve-shaped stomach. The reduced stomach size restricts food intake and leads to feelings of fullness with smaller amounts of food.

Adjustable Gastric Banding: This procedure involves placing an inflatable band around the upper part of the stomach, creating a smaller stomach pouch. The band can be adjusted to control the rate of food passage and the feeling of fullness.

Biliopancreatic Diversion with Duodenal Switch: This surgery combines a sleeve gastrectomy with bypassing a significant portion of the small intestine. It restricts food intake and reduces the absorption of calories and nutrients.

Weight loss surgery is usually recommended for individuals with a body mass index (BMI) of 40 or higher (severe obesity) or a BMI of 35 or higher with obesity-related health conditions such as type 2 diabetes, high blood pressure, or sleep apnea. It is considered when other weight loss methods, such as diet and exercise, have been unsuccessful.

Weight loss surgery is not a standalone solution but a tool to help individuals achieve significant weight loss and improve their overall health. It requires commitment to long-term lifestyle changes, including dietary modifications, regular exercise, and ongoing medical monitoring.

It's important to consult with a qualified bariatric surgeon and undergo a thorough evaluation to determine if weight loss surgery is a suitable option based on an individual's specific circumstances and health conditions.

 

What are the most common Bariatric surgery?

The most common types of bariatric surgery, also known as weight loss surgery, are:

Gastric Sleeve Surgery (Sleeve Gastrectomy): This procedure involves removing a large portion of the stomach to create a smaller, sleeve-shaped stomach. The reduced stomach size restricts food intake and promotes weight loss. It also affects the hunger hormone ghrelin, which helps reduce appetite.

Roux-en-Y Gastric Bypass: This surgery involves creating a small stomach pouch and rerouting the small intestine to connect to the pouch. The smaller stomach limits food intake, while the rerouted intestine bypasses a portion of the digestive tract, reducing nutrient absorption.

Adjustable Gastric Banding (Lap-Band): In this procedure, an inflatable band is placed around the upper part of the stomach, creating a small stomach pouch. The band can be adjusted to control the passage of food and create a feeling of fullness with smaller amounts of food.

These three surgeries are among the most commonly performed weight loss surgeries due to their effectiveness and relatively low risk compared to other procedures. They all work by reducing the capacity of the stomach or altering the digestive process to promote weight loss.

It's important to note that the choice of bariatric surgery depends on various factors, including a person's medical history, body mass index (BMI), overall health, and individual preferences. A thorough evaluation and consultation with a bariatric surgeon are necessary to determine the most suitable procedure for each individual's specific circumstances.
 

What is the procedure, risks and recovery for Gastric Bypass?

Gastric bypass surgery, also known as Roux-en-Y gastric bypass, is a weight loss procedure that involves creating a small stomach pouch and rerouting the small intestine. Here is an overview of the procedure, risks, and recovery associated with gastric bypass:

Procedure:

Creation of a small stomach pouch: The surgeon divides the top part of the stomach, creating a small pouch that can hold only a small amount of food.

Diverting the small intestine: The surgeon then connects the small stomach pouch to a lower section of the small intestine, bypassing a portion of the stomach and the first part of the small intestine.

Reconnecting the intestines: The bypassed portion of the intestine is then reconnected further down the digestive tract, allowing digestive juices to mix with food further along the intestine.

Risks:

Surgical risks: As with any surgery, gastric bypass carries risks such as bleeding, infection, adverse reactions to anesthesia, and blood clots.

Complications: Potential complications specific to gastric bypass include leaks at the surgical connections, narrowing of the opening between the stomach pouch and intestine (strictures), dumping syndrome (rapid emptying of the stomach contents into the small intestine), gallstones, and nutritional deficiencies.

Long-term risks: Some individuals may experience long-term complications such as ulcers, hernias, malnutrition, and bowel obstruction.

Recovery:

Hospital stay: After the surgery, patients usually stay in the hospital for 2 to 4 days to monitor their recovery and manage any postoperative issues.

Dietary progression: Patients start with a liquid diet and gradually transition to pureed and soft foods before reintroducing solid foods over time. Dietary guidelines are provided by the surgical team.

Follow-up care: Regular follow-up visits with the healthcare team are essential to monitor weight loss progress, manage any complications or concerns, and ensure proper nutritional intake.

Lifestyle changes: Successful recovery and weight loss require adopting healthy lifestyle habits, including regular exercise, dietary modifications, and ongoing medical monitoring.

It's crucial to consult with a qualified bariatric surgeon to fully understand the specific risks, recovery process, and individual considerations associated with gastric bypass surgery. Each person's experience and recovery may vary, and personalized guidance from healthcare professionals is essential for a successful outcome.

 

What is the procedure, risks and recovery for Sleeve Gastrectomy?

Sleeve gastrectomy, also known as gastric sleeve surgery, is a weight loss procedure that involves removing a large portion of the stomach to create a smaller, sleeve-shaped stomach. Here is an overview of the procedure, risks, and recovery associated with sleeve gastrectomy:

Procedure:

Laparoscopic approach: Sleeve gastrectomy is typically performed using minimally invasive laparoscopic techniques. Several small incisions are made in the abdomen, through which surgical instruments and a laparoscope (a thin tube with a camera) are inserted.

Stomach reduction: The surgeon removes approximately 75-80% of the stomach, leaving behind a small, sleeve-shaped pouch.

Stapling and closure: The remaining stomach is stapled closed along the length, creating the sleeve shape. The removed portion of the stomach is then removed from the body.

No rerouting of the intestines: Unlike gastric bypass, the intestines are not rerouted in sleeve gastrectomy.

Risks:

Surgical risks: As with any surgery, sleeve gastrectomy carries risks such as bleeding, infection, adverse reactions to anesthesia, blood clots, and injury to surrounding organs.

Complications: Potential complications specific to sleeve gastrectomy include leaks along the staple line, narrowing of the remaining stomach (stricture), acid reflux, hernias, and nutritional deficiencies.

Long-term risks: Some individuals may experience long-term complications such as ulcers, gallstones, malnutrition, and gastroesophageal reflux disease (GERD).

Recovery:

Hospital stay: After the surgery, patients typically stay in the hospital for 1 to 2 days to monitor their recovery and manage any postoperative issues.

Dietary progression: Patients begin with a liquid diet and gradually progress to pureed and soft foods before reintroducing solid foods over time. Dietary guidelines are provided by the surgical team.

Follow-up care: Regular follow-up visits with the healthcare team are important for monitoring weight loss progress, managing any complications or concerns, and ensuring adequate nutrition.

Lifestyle changes: Successful recovery and weight loss require adopting healthy lifestyle habits, including regular exercise, dietary modifications, and ongoing medical monitoring.

It's important to consult with a qualified bariatric surgeon to fully understand the specific risks, recovery process, and individual considerations associated with sleeve gastrectomy. Each person's experience and recovery may vary, and personalized guidance from healthcare professionals is crucial for a successful outcome.

 

What is the procedure, risks and recovery for Adjustable Gastric Banding?

Adjustable gastric banding, commonly known as lap-band surgery, is a weight loss procedure that involves placing an adjustable band around the upper part of the stomach to create a smaller stomach pouch. Here is an overview of the procedure, risks, and recovery associated with adjustable gastric banding:

Procedure:

Laparoscopic approach: Adjustable gastric banding is typically performed using minimally invasive laparoscopic techniques. Several small incisions are made in the abdomen, through which surgical instruments and a laparoscope (a thin tube with a camera) are inserted.

Placement of the band: The surgeon places an inflatable band around the upper part of the stomach, creating a small stomach pouch. The band is connected to an access port that is positioned under the skin of the abdomen.

Adjustability: The band can be adjusted by injecting or removing saline solution through the access port. This allows for tightening or loosening the band to control the passage of food and create a feeling of fullness with smaller amounts of food.

Risks:

Surgical risks: As with any surgery, adjustable gastric banding carries risks such as bleeding, infection, adverse reactions to anesthesia, blood clots, and injury to surrounding organs.

Band-related complications: Potential complications specific to gastric banding include band slippage or erosion, band intolerance, port-related issues (such as infection or leakage), and problems with the tubing connecting the band and port.

Long-term risks: Some individuals may experience long-term complications such as band intolerance, gastroesophageal reflux disease (GERD), esophageal dilation, or nutritional deficiencies.

Recovery:

Hospital stay: After the surgery, patients typically stay in the hospital for 1 to 2 days to monitor their recovery and manage any postoperative issues.

Dietary progression: Patients start with a liquid diet and gradually progress to pureed and soft foods before reintroducing solid foods over time. Dietary guidelines are provided by the surgical team.

Adjustments and follow-up care: The band may require adjustments over time to achieve optimal restriction. Regular follow-up visits with the healthcare team are important for band adjustments, monitoring weight loss progress, managing any complications or concerns, and ensuring adequate nutrition.

Lifestyle changes: Successful recovery and weight loss require adopting healthy lifestyle habits, including regular exercise, dietary modifications, and ongoing medical monitoring.

It's important to consult with a qualified bariatric surgeon to fully understand the specific risks, recovery process, and individual considerations associated with adjustable gastric banding. Each person's experience and recovery may vary, and personalized guidance from healthcare professionals is crucial for a successful outcome.

 

What is the procedure, risks and recovery for Biliopancreatic Diversion with Duodenal Switch?

Biliopancreatic diversion with duodenal switch (BPD-DS) is a complex weight loss surgery that combines a sleeve gastrectomy with bypassing a significant portion of the small intestine. Here is an overview of the procedure, risks, and recovery associated with BPD-DS:

Procedure:

Sleeve gastrectomy: The first part of the procedure involves removing a large portion of the stomach, leaving behind a smaller, sleeve-shaped stomach pouch. This restricts the amount of food that can be consumed.

Intestinal bypass: The surgeon then reroutes the small intestine, bypassing a significant length of the small intestine. This reduces the amount of surface area available for nutrient absorption.

Duodenal switch: The bypassed portion of the intestine is connected to the lower part of the small intestine, allowing digestive juices to mix with food further along the intestine.

Risks:

Surgical risks: BPD-DS is a more complex surgery than other weight loss procedures, and it carries risks such as bleeding, infection, adverse reactions to anesthesia, blood clots, and injury to surrounding organs.

Nutritional deficiencies: With the rerouting of the intestines and decreased absorption, there is a higher risk of nutritional deficiencies, including deficiencies in vitamins, minerals, and protein.

Dumping syndrome: Dumping syndrome, characterized by symptoms such as nausea, diarrhea, and lightheadedness after eating, can occur due to the rapid emptying of the stomach contents into the small intestine.

Long-term risks: Potential long-term risks include malnutrition, bowel obstruction, ulcers, hernias, and gastroesophageal reflux disease (GERD).

Recovery:

Hospital stay: After the surgery, patients typically stay in the hospital for 2 to 4 days to monitor their recovery and manage any postoperative issues.

Dietary progression: Patients start with a liquid diet and gradually progress to pureed and soft foods before reintroducing solid foods over time. Dietary guidelines are provided by the surgical team.

Follow-up care: Regular follow-up visits with the healthcare team are important for monitoring weight loss progress, managing any complications or concerns, and ensuring proper nutrition and supplementation.

Lifestyle changes: Successful recovery and weight loss require adopting healthy lifestyle habits, including regular exercise, dietary modifications, and ongoing medical monitoring.

It's essential to consult with a qualified bariatric surgeon to fully understand the specific risks, recovery process, and individual considerations associated with BPD-DS. This procedure is usually recommended for individuals with a higher BMI and significant obesity-related health conditions.
