In recent years bariatric surgery has become super popular for people struggling with obesity. But like any big medical decision, it’s important to know all the facts before you go. it is a variety of procedures designed to help with weight loss and it’s life-changing but it comes with risks.
Metabolic and Bariatric Surgery Overview
Metabolic and bariatric surgery refers to various surgeries to help people lose weight. These surgeries work by restricting how much food the stomach can hold or how the body absorbs nutrients. The goal of gastrointestinal surgery is to help people lose a lot of weight, get healthier, and reduce the risk of diabetes and heart disease.
Why is it Called Bariatric Surgery?
The term “bariatric” comes from the Greek word “baros,” meaning weight, and “strikes,” meaning medical treatment. Bariatric medicine refers to the branch of medicine that deals with the causes, prevention, and treatment of obesity.
What is the Difference Between Weight Loss Surgery and Bariatric Surgery?
Weight loss surgery and bariatric surgery are used interchangeably. However bariatric surgery is a type of weight loss surgery that addresses severe obesity. Other weight loss surgeries may be less invasive, bariatric weight loss surgery is for people with higher BMI and health risks.
What Are the Most Common Bariatric Surgery Procedures?
The most common bariatric surgeries include gastric bypass, gastric sleeve (sleeve gastrectomy), adjustable gastric band (lap-band), and biliopancreatic diversion with duodenal switch. Each of these procedures operates differently to aid in weight loss but all share the common goal of losing weight by reducing food intake or altering nutrient absorption.
What Does Bariatric Surgery Do?
The procedure physically alters the stomach, small intestine, and sometimes the intestines. By reducing the size of the stomach or rerouting parts of the small intestine through the digestive system, the surgery limits food intake and/or reduces nutrient absorption. The result is significant weight loss, which can help prevent or treat medical conditions such as Type 2 diabetes, high blood pressure, and sleep apnea.
Besides this, the service includes a comprehensive program that provides consultation, surgery, and post-operative care for patients. This service is typically offered by a multidisciplinary team that includes surgeons, dietitians, psychologists, and nurses specializing in both obesity treatment and management.
What is the Operation for Obesity?
Operations for obesity involve surgically altering the stomach or intestines to reduce food intake or nutrient absorption. Common operations include gastric bypass, sleeve gastrectomy, and biliopancreatic diversion.
What Does it Mean if a Patient is Bariatric?
A bariatric patient refers to someone who has undergone or is preparing to undergo bariatric surgery for the treatment of obesity. Bariatric patients often have a BMI of 40 or higher or a BMI of 35 or higher with obesity-related health conditions.
A 2024 study published by The Obesity Society reports that bariatric surgery can result in a loss of 50% to 70% of excess body weight within two years. The same study shows that nearly 60% of individuals maintain significant weight loss five years after surgery.
Surgery Bariatric – Candidacy and Requirements
To qualify for the procedure, the candidates must have a BMI of 40 or higher. However, some conditions, like untreated mental health issues, may delay or disqualify candidacy.
What is the Weight Cut-off for Bariatric Surgery?
There is no specific weight cut-off for bariatric surgery, but the BMI guidelines help healthcare professionals determine who may benefit most. Bariatric surgery is typically reserved for individuals with extreme body weight (BMI of 40+), though patients with a BMI of 35+ and health complications may also qualify.
Who Gets Denied for Bariatric Surgery?
Surgeons may deny patients if they do not meet the BMI or health condition requirements, have unresolved mental health issues, or are unable to commit to the necessary lifestyle changes post-surgery. A history of substance abuse or unresolved eating disorders may also disqualify a candidate.
How Does a Doctor Decide if You’re a Candidate for Bariatric Surgery?
Doctors assess a candidate’s BMI, medical history, and overall health when deciding if someone is suitable for the procedure. They also consider whether the patient has attempted other weight loss methods, the severity of obesity-related conditions, and the individual’s ability to commit to post-surgical care and lifestyle changes.
What is Considered a Bariatric Patient?
A bariatric patient is someone who is either undergoing or has undergone bariatric surgery to address severe obesity. These patients usually meet the criteria for the procedures based on their body mass index (BMI), health conditions, and medical history.
The American Society for Metabolic and Bariatric Surgery (ASMBS) reports that in 2024, roughly 24% of bariatric and metabolic surgery, candidates have a body mass index between 35 and 39.9 and suffer from at least one medical condition such as sleep apnea, Type 2 diabetes or hypertension.
Surgery Bariatric – Weight Loss Surgery Types and Safety
What Are the Most Common Obesity Surgical Procedures?
The most common obesity surgeries include gastric bypass, sleeve gastrectomy, adjustable gastric banding, and biliopancreatic diversion with duodenal switch. Each obesity surgery also offers different methods of reducing food intake or absorption to promote weight loss.
What Surgery is Done for Obesity?
Surgery for obesity typically involves reducing the size of the stomach or altering the digestive system. The most popular options are gastric bypass and sleeve gastrectomy, both of which help people achieve significant weight loss.
What Organ is Removed in Bariatric Surgery?
No organs are removed. However, in the case of sleeve gastrectomy, a large portion of the stomach is permanently removed to reduce its size. In gastric bypass, parts of the stomach and intestines are bypassed but not removed.
What is the New Surgery for Obesity?
A relatively new procedure gaining attention is endoscopic sleeve gastroplasty (ESG). Unlike traditional surgeries, ESG uses an endoscope to reduce the stomach’s size without large incisions. This procedure is minimally invasive and offers a quicker recovery time.
What is the Safest Bariatric Surgery for Weight Loss?
Bariatric surgeons consider gastric sleeve (sleeve gastrectomy) one of the safest bariatric surgeries. Comparatively, it’s a simpler surgical procedure rather than a gastric bypass. Additionally have fewer complications as well as a shorter recovery time. However, the safety of the surgery depends on the individual’s health and the bariatric surgeon’s expertise.
What Type of Surgery Might a Patient Have?
Individuals with extremely heavier body weight may undergo various bariatric surgeries depending on their health, weight loss goals, and medical history. The most common bariatric procedures include gastric bypass, sleeve gastrectomy, and adjustable gastric banding.
What is the Safest Surgery for Weight Loss?
Sleeve gastrectomy generally considered the safest bariatric surgery, but the safety and effectiveness vary based on individual factors. Choosing an experienced surgeon and following pre-and post-operative instructions are essential for ensuring a safe procedure.
How Do Different Bariatric Surgeries Compare in Terms of Effectiveness and Risk?
Gastric bypass typically results in the most rapid and substantial weight loss but carries higher risks, including malnutrition. Sleeve gastrectomy offers significant weight loss with less pain and fewer complications, while adjustable gastric banding is less than minimally invasive procedures but also less effective.
What is Gastric Sleeve Surgery, and How Does it Differ from Gastric Bypass?
Gastric sleeve surgery involves removing a large portion of the stomach to reduce its size, while gastric bypass surgery reroutes the digestive system to bypass parts of the smaller stomach and intestines. Gastric sleeve is less complex and has fewer long-term complications compared to gastric bypass.
According to a 2022 report from the ASMBS, sleeve gastrectomy accounts for nearly 60% of all bariatric weight loss surgeries being performed in the U.S., followed by gastric bypass at 17%. The complication rate for sleeve gastrectomy is reported at around 3%, making it one of the safer options for weight loss surgery.
