Bariatric Surgery, also known as weight loss surgery, refers to a set of surgical procedures designed to help individuals who are obese or severely overweight achieve significant and lasting weight loss. These surgeries are typically recommended for individuals who have been unsuccessful in achieving weight loss through non-surgical methods like diet and exercise, and whose obesity poses a serious risk to their health.
The primary objective of bariatric surgery is to modify either the size of the stomach or the process of digestion, leading to a decrease in the amount of food consumed and/or the absorption of nutrients being altered. By doing so, these procedures can help patients lose weight, improve or resolve obesity-related health conditions, and enhance their overall quality of life.
There are several different types of bariatric surgeries, each with its own mechanism of action and potential benefits. Some of the most common types of bariatric surgery include:
Gastric Bypass (Roux-en-Y Gastric Bypass): In this procedure, a small pouch is created near the top of the stomach. It's then connected directly to the small intestine, bypassing a part of the stomach and upper intestine. This helps limit the food you can eat and lower the number of calories your body absorbs.
Sleeve Gastrectomy: In this method, a big part of the stomach is taken out, making a smaller, curved shape "sleeve" that looks like a banana. This reduces the stomach's capacity and produces hormonal changes that can help control appetite and blood sugar levels. This reduces the stomach's capacity and produces hormonal changes that can help control appetite and blood sugar levels.
Adjustable Gastric Band (Lap-Band): A band is placed near the top of the stomach, making a tiny pocket. The ring can be changed to control how big the opening is between the pocket and the rest of the stomach, which helps control how much you eat.
Biliopancreatic Diversion with Duodenal Switch (BPD/DS): This complex procedure involves removing a part of the stomach, creating a smaller stomach pouch, and rerouting a significant portion of the small intestine. It combines restrictive and malabsorptive components to achieve weight loss.
Bariatric Revision Surgery: In some cases, individuals who have undergone previous bariatric surgeries may require revision surgery to address complications, inadequate weight loss, or other issues.
Bariatric Surgery
Bariatric Surgery is a Surgical weight loss intervention altering stomach size or digestive tract to aid in significant weight loss.
The purpose of bariatric surgery is to promote weight loss, improve or resolve obesity-related health problems, and enhance overall quality of life. Here are the main indications and purposes of bariatric surgery:
Indications:
Severe Obesity: Bariatric surgery is generally recommended for individuals with a body mass index (BMI) of 40 or higher. It may also be considered for those with a BMI of 35 or higher if they have significant obesity-related health conditions.
Obesity-Related Health Conditions: Bariatric surgery may be indicated for individuals with obesity-related health conditions that could be improved or resolved with weight loss. These conditions include type 2 diabetes, hypertension (high blood pressure), sleep apnea, high cholesterol, non-alcoholic fatty liver disease, and more.
Failure of Non-Surgical Methods: Candidates for bariatric surgery are often individuals who have tried and failed to achieve substantial and sustainable weight loss through conventional methods such as diet, exercise, and behavioral modifications.
Motivation and Commitment: Candidates for bariatric surgery should demonstrate a commitment to making necessary lifestyle changes post-surgery, including adopting a healthier diet, increasing physical activity, and attending regular follow-up appointments.
Purposes:
Weight Loss: The primary purpose of bariatric surgery is to promote significant and lasting weight loss. By reducing the size of the stomach or altering the digestive process, these procedures limit the amount of food that can be consumed and/or absorbed, leading to weight loss over time.
Improvement of Obesity-Related Health Conditions: Bariatric Surgery can lead to substantial improvements or even complete resolution of obesity-related health conditions such as hypertension, type 2 diabetes, sleep apnea, and more. This can significantly lower the risk of complications and improve overall health.
Enhanced Quality of Life: Successful weight loss through bariatric surgery can improve a person's quality of life by increasing mobility, reducing joint pain, improving self-esteem, and enhancing overall well-being.
Long-Term Weight Maintenance: Bariatric surgery can help patients achieve better long-term weight maintenance compared to non-surgical methods. However, it's important to note that ongoing commitment to a healthy lifestyle, including dietary changes and regular exercise, is crucial for maintaining weight loss.
Reduction of Mortality Risk: Bariatric surgery has been associated with a reduction in overall mortality risk in severely obese individuals, particularly when obesity-related health conditions are improved or resolved.
Steps involved in Bariatric Surgery
During a bariatric surgery procedure, several specific steps are taken to achieve the desired weight loss and metabolic changes. The exact details may vary depending on the type of surgery being performed, but here's a general overview of what happens during bariatric surgery:
Anesthesia:
You will be administered anesthesia to ensure you are comfortable and pain-free during the procedure.
Incisions:
Small incisions are made in the abdomen to allow the surgeon access to the surgical area. Some surgeries may be performed using minimally invasive techniques (laparoscopic surgery) with small instruments and a camera.
Access to the Stomach:
The surgeon gains access to the stomach and digestive tract through the incisions.
Surgical Technique:
Depending on the type of bariatric surgery, different techniques are employed:
Gastric Bypass (Roux-en-Y): The surgeon creates a small pouch at the top of the stomach and connects it to a lower portion of the small intestine, bypassing a section of the stomach and small intestine.
Sleeve Gastrectomy: A large portion of the stomach is removed, leaving a smaller, banana-shaped "sleeve."
Gastric Banding (Lap-Band): A band is placed around the top part of the stomach to create a small pouch.
Biliopancreatic Diversion with Duodenal Switch (BPD/DS): A portion of the stomach is removed, creating a smaller pouch, and a larger portion of the small intestine is bypassed.
Closure and Healing:
The incisions are carefully closed using sutures or staples, and the healing process begins.
Recovery and Monitoring:
Following the operation, you'll be moved to a recovery zone, where healthcare experts will keep an eye on your important signs and ensure you're safely awakening from anesthesia.
Hospital Stay:
Depending on the type of surgery and your individual condition, you may stay in the hospital for a few days to recover and receive post-operative care.
Diet Progression:
You'll begin by drinking clear liquids and then slowly move on to mushy foods and finally regular foods, all based on the special instructions given by your healthcare experts.
Follow-up Care:
Regular check-up appointments will be scheduled to monitor your progress, adjust medications, and provide guidance on diet and lifestyle changes.
Who will do Bariatric Surgery:
Bariatric surgery is performed by a specialized medical professional known as a bariatric surgeon or a metabolic surgeon. These surgeons have undergone specific training and have expertise in the surgical management of obesity and related health conditions. Bariatric Surgery is a complicated medical procedure that demands specialized expertise and abilities to guarantee the Surgery's safety and achievement.
Bariatric surgeons typically have a background in general surgery and undergo additional training and education to become experts in the field of bariatric surgery. They work closely with a multidisciplinary team of healthcare professionals, including dietitians, psychologists, nurses, and other specialists, to provide comprehensive care before and after surgery.
Preparing for bariatric surgery involves a series of important steps to ensure that you are physically, mentally, and emotionally ready for the procedure and the lifestyle changes that follow. Here's a comprehensive guide on how to prepare for bariatric surgery:
