What is Bariatric Surgery?

Bariatric surgery is a procedure to aid very overweight people in losing weight. It changes the digestive system to reduce how much a person can eat or absorb. Such surgeries help in losing weight and can make diseases like diabetes or sleep apnea better or go away.

Eligibility Criteria for Bariatric Surgery, Not everyone can get bariatric surgery, Why?

Not everyone can get bariatric surgery, even if they are very overweight. There are rules to follow. For example, your BMI must show severe obesity or less severe obesity plus a health issue linked to obesity. Before the surgery, you must also have tried to lose weight through diet and exercise with help for at least two years.

Many of my patients come into my office saying, «Dr Santiago, I want you to give me a gastric sleeve,» but it’s not that simple. Each patient must meet minimum requirements before being considered for bariatric surgery. It’s crucial to understand that this procedure is not a quick fix, but rather a tool to aid in long-term weight loss and improved health.

After meeting the requirements, you should be prepared to make some lifestyle changes. The surgeon will evaluate you and provide guidance on what your new way of eating will look like. This ensures that the surgery is the right choice and that you are prepared for everything it entails.

«We want to make sure our patients are not only physically prepared for surgery but also mentally and emotionally ready to commit to the necessary changes in their eating habits and lifestyle to achieve lasting success,» says Dr. Santiago Gomez Correa, Bariatric Surgeon.«We want to make sure our patients are not only physically prepared for surgery but also mentally and emotionally ready to commit to the necessary changes in their eating habits and lifestyle to achieve lasting success,» says Dr. Santiago Gomez Correa, Bariatric Surgeon.

The Role of BMI in Bariatric Surgery Eligibility

Body Mass Index (BMI) is a crucial factor in determining a patient’s eligibility for bariatric surgery. BMI is a measure of body fat based on an individual’s weight and height, and it helps classify obesity levels. To calculate BMI, divide a person’s weight in kilograms by their height in meters squared (kg/m²).

BMI calculator

BMI Range Classification Eligibility for Bariatric Surgery
18.5 - 24.9 Normal weight Not eligible
25.0 - 29.9 Overweight Not eligible
30.0 - 34.9 Class I Obesity elegible
35.0 - 39.9 Class II Obesity Eligible with at least one obesity-related comorbidity
40.0 and above Class III Obesity (Morbid Obesity) Eligible

In general, a BMI of 30 or above indicates obesity, while a BMI of 40 or higher (or 35 and up with obesity-related health issues) is considered severe obesity. Patients with Obesity grade I or severe obesity are typically eligible for bariatric surgery, as they have a higher risk of developing serious health problems and may struggle to achieve significant weight loss through conventional methods like diet and exercise alone.

However, BMI is not the sole determinant of bariatric surgery eligibility. Other factors, such as the presence of obesity-related health conditions (e.g., type 2 diabetes, high blood pressure, sleep apnea), age, and overall health status, also play a role in the decision-making process. A comprehensive evaluation by a certified bariatric surgeon is necessary to assess a patient’s suitability for surgery and to develop a personalized treatment plan.

It’s important to note that while BMI is a useful screening tool, it does have limitations. BMI does not distinguish between muscle mass and body fat, nor does it account for fat distribution. Therefore, additional assessments, such as body composition analysis and waist circumference measurements, may be used in conjunction with BMI to gain a more complete understanding of a patient’s obesity-related health risks.

Methods of Bariatric Surgery: Restrictive and Malabsorptive Procedures

According to Dr. Santiago Gómez Correa, a renowned bariatric surgeon based in Medellín, Colombia, the method applied in bariatric surgery depends on the specific type of procedure being performed. The two main categories of bariatric surgery methods are restrictive and malabsorptive.

Restrictive Method: Gastric Sleeve Surgery

Gastric Sleeve vs Bypass Dr Santiago Gómez Cirujano Bariátrico en Medellín_

Gastric sleeve surgery, also known as sleeve gastrectomy, is a restrictive method of bariatric surgery. This procedure removes a significant portion of the stomach, leaving behind a narrow, banana-shaped «sleeve.» Reducing the size of the stomach limits the amount of food one can consume in one sitting, resulting in a feeling of fullness with smaller portions. This restrictive method helps patients lose weight by decreasing their caloric intake.

The hormonal changes associated with gastric sleeve surgery also contribute to weight loss. The portion of the stomach removed during the procedure contains cells that produce ghrelin, the «hunger hormone.» By eliminating these cells, appetite is reduced, further aiding in weight loss efforts.

Gastric Bypass Surgery: A Restrictive and Malabsorptive Method.

Gastric Sleeve vs Bypass Dr Santiago Gómez Cirujano Bariátrico en Medellín_

Gastric bypass surgery, specifically the Roux-en-Y gastric bypass, is a combination of restrictive and malabsorptive methods. This procedure involves creating a small pouch at the top of the stomach and connecting it directly to the small intestine, bypassing the rest of the stomach and the upper part of the small intestine (duodenum).

Gastric bypass surgery shares a restrictive component with gastric sleeve surgery, as the small pouch restricts the amount of food consumed. However, the malabsorptive aspect of the procedure further enhances weight loss by reducing the absorption of nutrients and calories in the small intestine. By bypassing a portion of the small intestine, the body absorbs fewer calories from the food consumed.

As a bariatric surgeon, I frequently emphasize that the combination of restrictive and malabsorptive methods in gastric bypass surgery often leads to more significant and rapid weight loss than purely restrictive procedures like gastric sleeve surgery. However, I also note that the malabsorptive component of gastric bypass surgery may increase the risk of nutritional deficiencies, requiring patients to adhere to a strict supplementation regimen and follow-up with their bariatric team.

Roux en Y Gastric Bypass: The Procedure

Roux en Y gastric bypass is a powerful surgery for weight loss. It mixes two methods. One is making the stomach smaller to eat less. The other cuts how much nutrient the body takes in. This surgery helps reduce weight and improve obesity-related health issues.

How Roux en Y Gastric Bypass Works

This surgery creates a tiny stomach pouch the size of an egg. We staple off the upper part of the stomach to form this pouch. The small intestine is then split.

The new stomach connects to the bottom part. This bypasses a significant portion of the stomach and the beginning of the small intestine. As a result, the body absorbs fewer nutrients and calories, aiding in weight loss.

Advantages of Roux en Y Gastric Bypass

Advantage Description
Greater weight loss Patients often lose up to 70% of excess body weight within the first year
Improvement incomorbidities Type 2 diabetes, hypertension, and other obesity-related conditions may improve or resolve
Betterlong-term weight loss maintenance Combination of restrictive and malabsorptive mechanisms contributes to sustained weight loss

Roux en Y gastric bypass can lead to more weight loss than other surgeries. In the first year, patients often shed up to 70% of extra body weight. This procedure can also quickly improve or cure problems like type 2 diabetes.

Its mix of reducing food intake and fewer nutrients also helps people maintain weight loss better over time.

Disadvantages of Roux en Y Gastric Bypass

Disadvantage Description
Lifelong vitamin and mineral supplementation Malabsorption necessitates daily supplementation to prevent nutritional deficiencies
NSAID avoidance Non-steroidal anti-inflammatory drugs can increase the risk of marginal ulcers and anastomotic complications
Internal hernia risk Intestines may become trapped in pockets created during the rerouting process, requiring surgical intervention

But there are downsides to Roux en Y. A big one is the need for taking vitamins and minerals for life. This is because the body won’t absorb them well anymore. Common deficiencies are in iron, calcium, and certain vitamins.

Gastric Sleeve: The Procedure

Another name for gastric sleeve surgery is sleeve gastrectomy. It’s a type of restrictive bariatric surgery. It involves taking out a large part of the stomach. This surgery has become popular for its success in helping people lose weight. It also has a quicker recovery time when compared to other bariatric surgeries.

How Gastric Sleeve Surgery Works

The surgeon takes out about 80% of the stomach during the gastric sleeve procedure. This leaves a banana-shaped stomach pouch. Having a smaller stomach makes patients feel full faster. This is because they can’t eat as much. The surgery also causes hormonal changes. These changes help reduce hunger and aid in losing weight.

Gastric Sleeve Surgery's Advantages

One main advantage is how much weight people can lose. After surgery, people shed about 60–70% of their extra weight in the first year. This occurs because the surgery reduces stomach size and alters hormone function. This leads to strong support for losing weight.

After this surgery, getting back to normal is quicker than with other types of weight-loss surgery. Most people resume their normal activities within 2–4 weeks. This quick recovery lets people start their new life sooner. They can adopt healthier habits faster.

Disadvantages of Gastric Sleeve Surgery

There are some downsides to consider. One is that acid reflux could get worse or start after surgery. This happens because of the changes in the stomach. Managing this might require lifelong medication or even more surgeries.

Like any surgery, there are general risks to think about. These include the chance of bleedinginfection, or not reacting well to the anesthesia. But when the surgery is done by a skilled bariatric surgeon in a good facility, these risks are usually very low.

Improvement in Obesity-Related Comorbidities

Bariatric surgery, like Roux en Y gastric bypass and gastric sleeve, greatly helps with obesity-related issues. These surgeries aid in losing weight and improving health. This means a better life for patients.

One of the greatest moments of satisfaction I experience is when my patients tell me that thanks to bariatric surgery, they thank me because, besides losing weight, their health has improved. These success stories motivate me to continue working for the health and wellbeing of everyone. 

Bariatric surgery, like Roux en Y gastric bypass and gastric sleeve, greatly helps with obesity-related issues. These surgeries aid in losing weight and improving health. This means a better life for my patients. Several diseases improve with bariatric surgery:

Bariatric surgery can put type 2 diabetes into remission. The Roux en Y gastric bypass surgery is very effective. Even before significant weight loss, it helps with diabetes.

The surgery changes hormones, improving how the body uses insulin and glucose.

Obesity often leads to high blood pressure. Both bypass and sleeve surgeries reduce the risk. As patients lose weight, their hearts and blood vessels need to work less hard.

This helps lower blood pressure. Many people can stop taking high blood pressure pills after surgery.

Obesity can cause sleep apnea, which occurs when breathing stops and starts during sleep. Bariatric surgery can improve this condition. It eases the pressure on the breathing airway.

After surgery, many patients sleep better and feel less fatigued during the day. Some might not need CPAP therapy anymore.

What is CPAP?

According to National Hear, Jung, and blood Institute ( CPAP (continuous positive airway pressure) is a machine that uses mild air pressure to keep breathing airways open while you sleep.  Your healthcare provider may prescribe CPAP to treat sleep-related breathing disorders including sleep apnea. CPAP also may treat preterm infants who have underdeveloped lungs.

Gastroesophageal Reflux Disease (GERD)

The impact of bariatric surgery on GERD varies depending on the type of surgery. The Roux en Y bypass can often stop GERD symptoms by reducing acid. But take in mind the gastric sleeve might make GERD worse.

Surgery choice should consider existing GERD. It is vital to look at which surgery may be best for each patient’s situation.

Quality of Life after Bariatric Surgery


Getting bariatric surgery, like the Roux en Y gastric bypass or gastric sleeve, can change a patient’s life for the better. It helps people with severe obesity get healthier. They start to move easier, have more energy, and feel better overall.

The surgery doesn’t just make people physically better. Their minds become healthier, they feel better about themselves, and their friendships grow stronger. After losing weight, they are more outgoing and enjoy new things.

Many patients express a newfound sense of freedom and joy in their daily lives after successful bariatric surgery. They feel more capable, energetic, and optimistic about the future.

Scientists have looked into how bariatric surgery changes the quality of people’s lives. They used tools like the GIQLI and BAROS.

For many of my patients, bariatric surgery marks a turning point in their life. It’s not just about losing weight. These procedures help them move better, feel happier, and enjoy time with others.

Recovery and Lifestyle Changes

Recovering from bariatric surgery takes time and commitment. Patients slowly move from a liquid diet to solid foods in a few weeks. They must follow a strict diet after surgery for healing and to succeed in the long run. Starting with clear liquids, they move to pureed, and then soft and regular foods. Patients need to eat small, nutrient-packed meals. This helps them get all the needed nutrients while losing weight.

Lifestyle changes are also key to lasting weight loss.

  • Staying hydrated with water and low-calorie drinks all day
  • Regular exercise involves starting small and gradually increasing the intensity.
  • Eating mindfully, like chewing well and eating slowly without distractions,
  • Keeping in touch with doctor

Right after surgery, patients should take time off work (one week) to let their bodies heal. Returning to work can take 2-3 weeks, depending on the job and operation type. Light exercise, like walking, is okay a few days post-surgery. You can gradually resume more intense activities.

«The key to successful weight loss after bariatric surgery is a combination of a healthy diet, regular exercise, and a strong support system. Patients who embrace these lifestyle changes and work closely with their healthcare team are more likely to achieve their goals and maintain long-term success.» – Dr. Sarah Thompson, Bariatric Surgeon

Choosing the Right Bariatric Surgeon

When looking at bariatric surgery, pick a surgeon wisely. A good bariatric surgeon can get you great results and lower your risks. They should be board-certified, very experienced in your needed surgery, and show they’ve helped others well.

The importance of having an experienced and qualified surgeon is paramount.

An experienced surgeon knows everything, from preparing for surgery to taking care of you after. They help you see the positive and bad of surgery, answer your questions, and suggest what’s best for you. A competent surgeon can also fix any problems that might come up.

Body Composition Analysis and Waist Circumference Measurements

Understanding your body’s health goes beyond just stepping on a scale. It’s important to look at both the composition of your body and specific measurements like waist circumference to get a clearer picture of your overall health. Body composition analysis and waist circumference measurements are two essential methods that provide detailed insights into your body’s makeup and potential health risks. You can use these tools to set more accurate health goals, monitor your progress effectively, and make informed decisions about your fitness and nutrition. In this section, we’ll explore how these methods work and why they are crucial for maintaining a healthy lifestyle.

Body Composition Analysis

Body composition analysis is an essential method to understand the various components that make up an individual’s body weight, including muscle mass, fat mass, and bone density. Unlike simple weight measurements, this analysis provides a detailed breakdown of the body’s structure, allowing for a more accurate assessment of health and fitness levels. By distinguishing between lean mass and fat mass, body composition analysis helps in setting realistic goals for weight loss, muscle gain, and overall health improvement. 

Waist Circumference Measurements

Waist circumference measurement is a straightforward yet powerful tool for assessing abdominal fat and related health risks. It involves measuring the distance around the smallest area below the rib cage and above the belly button. Excess abdominal fat increases the risk of chronic conditions like heart disease, type 2 diabetes, and metabolic syndrome, making this measurement crucial. Waist circumference provides more information than BMI, especially in cases where BMI may not accurately reflect fat distribution. Health professionals use this measurement to identify individuals at greater risk and to monitor changes in abdominal fat over time, making it an integral part of health assessments and weight management programs.

Both body composition analysis and waist circumference measurements are invaluable in providing a comprehensive picture of an individual’s health. These methods go beyond traditional weight measurements, offering deeper insights into body fat distribution and potential health risks. By incorporating these tools into regular health assessments, individuals can better understand their bodies and make informed decisions about their fitness and health journeys.

Choosing between Roux en Y gastric bypass and gastric sleeve surgery is personal. It requires consideration and guidance from a qualified surgeon. Both surgeries help patients lose a lot of weight and get healthier from obesity-related issues. But, they each have their own good points, possible problems, and risks. These depend on the person’s life and health goals.

Understanding the main differences between these surgeries is crucial for those dealing with serious obesity. This knowledge will help them choose what’s best for their needs. Things like BMI, other health conditions, and how someone lives all matter. These factors help decide if Roux en Y or gastric sleeve is a better choice.

Success with weight loss surgery is about more than just picking the right operation. It also means working with experts like Dr. Santiago Gómez. He can offer the best advice and support. Committing to lifestyle changes also matters a lot. With the right support and effort, patients can see big improvements in their health and lives. This makes choosing weight loss surgery goals worthwhile.

FAQ - Roux en Y vs Gastric Sleeve:

The primary difference between Roux en Y gastric bypass and gastric sleeve surgery lies in their mechanisms. Roux en Y combines restrictive and malabsorptive methods, creating a small stomach pouch and bypassing part of the small intestine, reducing nutrient absorption. Gastric sleeve surgery is solely restrictive, involving the removal of a large portion of the stomach, leaving a smaller, sleeve-shaped stomach that limits food intake.


Roux en Y gastric bypass aids in weight loss by creating a small stomach pouch that limits food intake and bypassing a portion of the small intestine, reducing calorie and nutrient absorption. This combination of restriction and malabsorption leads to significant weight loss and improvements in obesity-related conditions.

Gastric sleeve surgery aids in weight loss by removing about 80% of the stomach, leaving a narrow, sleeve-shaped stomach. This reduction in stomach size limits the amount of food that can be consumed, leading to a feeling of fullness with smaller portions. Additionally, the surgery reduces levels of the hunger hormone ghrelin, which further helps decrease appetite and promote weight loss.

The benefits of Roux en Y gastric bypass surgery include significant weight loss, rapid improvement or resolution of obesity-related conditions such as type 2 diabetes, hypertension, and sleep apnea, and long-term maintenance of weight loss. This procedure also helps patients achieve better health outcomes and improves their quality of life.

The benefits of gastric sleeve surgery include substantial weight loss, reduced hunger due to lower ghrelin levels, improvement or resolution of obesity-related conditions, and a relatively quicker recovery time compared to other bariatric surgeries. Patients also experience enhanced quality of life and improved overall health.

The potential risks associated with Roux en Y gastric bypass include nutritional deficiencies (such as iron, calcium, and certain vitamins), the need for lifelong supplementation, surgical complications (such as infection, bleeding, and anastomotic leaks), and a higher risk of dumping syndrome. These risks necessitate careful monitoring and follow-up with the bariatric team.

The potential risks associated with gastric sleeve surgery include the possibility of developing or worsening acid reflux, surgical complications (such as bleeding, infection, and leaks), and the need for lifelong dietary changes and supplementation. Despite these risks, the procedure is generally safe when performed by an experienced bariatric surgeon.

Both Roux en Y gastric bypass and gastric sleeve surgery are effective for long-term weight maintenance, though Roux en Y generally results in greater and more sustained weight loss. Gastric sleeve surgery also provides significant weight loss but may require more stringent lifestyle modifications to maintain results. Long-term success in both cases depends on adherence to dietary guidelines, regular exercise, and ongoing medical follow-up.

Lifestyle changes required after bariatric surgery include adopting a nutrient-rich diet, eating smaller, frequent meals, staying hydrated, engaging in regular physical activity, taking prescribed vitamin and mineral supplements, avoiding high-calorie and sugary foods, and attending regular follow-up appointments with the healthcare team to monitor progress and address any issues.

BMI (Body Mass Index) plays a crucial role in determining eligibility for bariatric surgery. Candidates typically have a BMI of 40 or higher, or a BMI of 35 or higher with obesity-related health conditions such as type 2 diabetes, hypertension, or sleep apnea. BMI helps classify the severity of obesity and assess the potential health benefits of the surgery.

BMI is calculated by dividing a person’s weight in kilograms by their height in meters squared (kg/m²). The formula is: BMI = weight (kg) / [height (m)]². This calculation provides an estimate of body fat and helps categorize individuals into weight status categories such as underweight, normal weight, overweight, and obese.

The eligibility criteria for bariatric surgery include having a BMI of 40 or higher, or a BMI of 35 or higher with obesity-related health conditions, failing to achieve significant weight loss through diet and exercise, being between the ages of 18 and 65, and undergoing a thorough medical and psychological evaluation to ensure suitability for the procedure and commitment to the necessary lifestyle changes.

Comorbidities such as type 2 diabetes, hypertension, sleep apnea, and other obesity-related conditions significantly affect the decision for bariatric surgery. The presence of these conditions increases the urgency and potential benefits of the surgery, as it can lead to their improvement or resolution, enhancing the patient’s overall health and quality of life.

Body composition analysis is a method used to measure the different components that make up a person’s body, including muscle mass, fat mass, and bone density. It is important because it provides a more detailed understanding of an individual’s health and fitness levels than simple weight measurement, helping to set realistic health goals and develop personalized nutrition and exercise plans.

Waist circumference is measured by placing a measuring tape around the smallest area below the rib cage and above the belly button. It is significant because it helps assess abdominal fat, which is a risk factor for chronic conditions like heart disease, type 2 diabetes, and metabolic syndrome. Waist circumference provides additional information beyond BMI, particularly regarding fat distribution.

The hormonal changes associated with gastric sleeve surgery include a significant reduction in the production of ghrelin, the hunger hormone, due to the removal of a large portion of the stomach where ghrelin is produced. This reduction in ghrelin levels leads to decreased appetite and contributes to weight loss.

The malabsorptive component of Roux en Y gastric bypass affects nutrient intake by bypassing a portion of the small intestine, reducing the absorption of calories, vitamins, and minerals. This leads to significant weight loss but also increases the risk of nutritional deficiencies, necessitating lifelong supplementation and careful dietary management.

Common nutritional deficiencies after Roux en Y gastric bypass surgery include deficiencies in iron, calcium, vitamin B12, vitamin D, and folate. These deficiencies occur due to reduced nutrient absorption and require lifelong supplementation and regular monitoring to prevent and manage them effectively.

Gastric sleeve surgery can impact GERD (gastroesophageal reflux disease) in different ways. While it may alleviate GERD symptoms in some patients due to weight loss and reduced pressure on the abdomen, it can worsen or cause new onset GERD in others due to changes in the stomach’s structure and function. Patients with pre-existing GERD should discuss potential risks with their surgeon.

The typical recovery time for Roux en Y gastric bypass surgery involves an initial hospital stay of 2 to 3 days, followed by a gradual return to normal activities over 4 to 6 weeks. Patients must adhere to a specific diet progression from liquids to solids and gradually resume physical activities as advised by their healthcare team.

Bariatric surgery improves type 2 diabetes by inducing significant weight loss, which enhances insulin sensitivity and glucose metabolism. Procedures like Roux en Y gastric bypass also alter gut hormones, leading to improved blood sugar control. Many patients experience remission or substantial improvement in diabetes symptoms post-surgery.

CPAP (Continuous Positive Airway Pressure) therapy is a treatment for sleep apnea that uses a machine to deliver a continuous stream of air through a mask, keeping the airways open during sleep. It is related to sleep apnea because it helps prevent the airway collapses that cause interruptions in breathing, thereby improving sleep quality and reducing the associated health risks.

Patients should prepare mentally and emotionally for bariatric surgery by attending counseling sessions, joining support groups, and setting realistic expectations for the outcomes. Understanding the lifestyle changes required post-surgery, such as dietary modifications and increased physical activity, is crucial. Patients should also develop a strong support system to help them navigate the emotional challenges that may arise during their weight loss journey.

When choosing a bariatric surgeon, consider their certification and experience, success rates, patient reviews, and the quality of the healthcare facility where they practice. It’s also important to assess the surgeon’s approach to patient care, including preoperative and postoperative support, availability for follow-up appointments, and the comprehensiveness of the weight loss program they offer.

The advantages of seeking bariatric surgery in Colombia include access to highly skilled surgeons, state-of-the-art medical facilities, and cost savings compared to procedures in the United States or Europe. Colombia is known for its medical tourism, offering high-quality care at more affordable prices. Additionally, the warm climate and beautiful surroundings provide a conducive environment for postoperative recovery.
