Difference between Gastric Sleeve and Bariatric Surgery

Difference between Gastric Sleeve and Bariatric Surgery

Gastric Sleeve vs Bariatric Surgery

Obesity is a growing issue in societies around the world, with millions of people struggling to lose weight. For those who have struggled with traditional weight loss methods, such as diet and exercise, bariatric surgery may be an option worth considering. Among the most popular procedures are gastric sleeve and bariatric surgery. But what’s the difference between the two, and which one is the best option?

The gastric sleeve, also known as vertical sleeve gastrectomy (VSG), is a restrictive procedure that aims to decrease the size of the stomach by about 60-80%. During the surgery, the surgeon will remove a large portion of the stomach leaving a small banana-shaped tube, which restricts the amount of food that can be consumed. One of the primary benefits of this procedure is that it not only reduces the stomach size, but it also reduces the level of hunger hormones, which help with weight loss.

Bariatric surgery is a more extensive procedure that includes a variety of surgical options designed to help obese individuals lose weight. It includes more invasive operations such as gastric bypass and duodenal switch, as well as restrictive procedures such as the gastric sleeve. The aim of bariatric surgery is to curb appetite, promote satiety, and ultimately promote weight loss.

So what’s the key difference between these two procedures? While both are effective at helping individuals achieve substantial weight loss, bariatric surgery is a more complex and invasive procedure than the gastric sleeve. Bariatric surgery typically involves rerouting part of the intestine to reduce calorie absorption, while gastric sleeve surgery simply restricts the stomach size.

Another difference is the long-term effectiveness. Bariatric surgery often results in more significant weight loss in the first year compared to gastric sleeve surgery. Still, research suggests that both procedures can be effective in weight loss maintenance in the long term. However, it’s important to note that both procedures require lifestyle changes, such as following a healthy diet and regular exercise to achieve the best results.

In conclusion, deciding between gastric sleeve and bariatric surgery requires a discussion with a medical professional after determining if surgery is the right weight loss option for your specific situation. While both procedures are effective, they differ in invasiveness, weight loss speed, and long-term effectiveness. Ultimately, the right choice comes down to what works best for the individual concerning their unique needs and health situation.

What is Sleeve Gastrectomy?

Sleeve Gastrectomy

Sleeve gastrectomy, also known as gastric sleeve surgery, is a weight loss procedure that involves the removal of a portion of the stomach. The remaining portion of the stomach is then shaped into a long, narrow tube, which resembles a “sleeve”. This procedure restricts the amount of food that can be consumed and also results in hormonal changes that help to promote weight loss.

Sleeve gastrectomy is usually recommended for individuals who have a BMI (body mass index) over 40 or for those with a BMI between 35 and 40 who have related health problems like high blood pressure or diabetes. This surgery is considered to be a relatively safe and effective way to achieve significant weight loss and improve overall health.

The procedure is usually performed laparoscopically, which means that it is minimally invasive and involves making small incisions in the abdomen. Through these small incisions, a camera and surgical instruments are inserted to perform the surgery. The surgeon removes a large, curved section of the stomach, leaving behind a tube-shaped structure that is about the size of a banana.

After the surgery, patients are usually required to stay in the hospital for a few days to recover. They are then given a very strict diet plan to follow which usually includes only liquids and soft foods in the beginning and gradually moving towards more solid foods over time. Patients are also advised to exercise regularly and to make lifestyle changes that support successful weight loss.

While sleeve gastrectomy may seem like an extreme measure to lose weight, it is often a very effective option for those who have struggled with obesity and related health problems for many years. Most patients experience significant weight loss in the first few months after the surgery and find that their overall health improves as well.

What is Bariatric Surgery?

Bariatric surgery is a procedure that is designed to help obese individuals lose weight. It involves several different surgical techniques that work to reduce the size of the stomach, restrict the amount of food that can be consumed and alter the process of digestion. The aim of these techniques is to help people lose weight and improve their overall health and wellbeing.

The two most popular types of bariatric surgery are gastric bypass and gastric sleeve surgery. Gastric bypass surgery involves creating a small pouch at the top of the stomach and attaching it to the small intestine. This reduces the amount of food that can be eaten and the body’s ability to absorb calories. Gastric sleeve surgery, on the other hand, involves reducing the size of the stomach by removing a portion of it. By making the stomach smaller, a patient will feel fuller sooner and eat less.

One of the main advantages of bariatric surgery over other weight-loss methods is its ability to provide long-term results. Studies have shown that the majority of patients who undergo bariatric surgery lose a significant amount of weight and keep it off for at least five years. This is particularly beneficial for individuals who have tried other weight-loss methods without long-term success.

However, bariatric surgery is not a solution for everyone. It is generally reserved for individuals who have a body mass index (BMI) of 40 or above or a BMI of 35 or above with a weight-related health condition such as diabetes or high blood pressure. Additionally, patients must be committed to making lifestyle changes after surgery to ensure that they maintain their weight loss.

In conclusion, bariatric surgery is a surgical procedure that can help obese individuals lose weight through reduced stomach capacity and/or altered digestion. It has been proven to provide long-term weight loss and improved overall health, but it should only be considered after careful evaluation and discussion with a qualified medical professional.

¿Cómo se diferencian la manga gástrica y la cirugía bariátrica?

Manga gástrica y cirugía bariátrica

La obesidad es una enfermedad crónica que afecta a millones de personas en todo el mundo. Si bien la dieta y el ejercicio son métodos efectivos para perder peso, a veces no son suficientes para tratar esta afección. En estos casos, la cirugía bariátrica puede ser una alternativa viable.

La manga gástrica es una de las opciones de cirugía bariátrica disponibles. Esta técnica quirúrgica implica la extirpación de una gran parte del estómago, por lo que solo queda una manga estrecha. Como resultado, el paciente se siente lleno más rápido, se come menos y pierde peso de manera efectiva.

En comparación con otras técnicas de cirugía bariátrica, la manga gástrica es relativamente nueva, ya que fue desarrollada a principios del siglo XXI. Pero, ¿cómo se diferencia de otros tipos de cirugía bariátrica?

Banda gástrica

Banda gástrica

La banda gástrica es otro tipo de cirugía bariátrica. Este procedimiento implica la colocación de una banda ajustable alrededor del estómago, que puede ajustarse para controlar la cantidad de alimento que el estómago puede aceptar. El efecto neto es hacer que el paciente se sienta lleno con porciones más pequeñas, lo que lo lleva a perder peso.

En comparación con la manga gástrica, la banda gástrica es reversible y no requiere la extirpación de ninguna porción del estómago. Además, la banda gástrica se puede ajustar, lo que permite controlar con precisión la cantidad de alimento que el estómago puede aceptar. Sin embargo, la banda gástrica también puede tener mayores tasas de fracaso, y algunos pacientes pueden recuperar el peso después del procedimiento.

Bypass gástrico

Bypass gástrico

El bypass gástrico es un procedimiento que implica la creación de una pequeña bolsa de estómago en la parte superior del estómago, que se conecta directamente al intestino delgado. La bolsa de estómago es mucho más pequeña que el estómago normal, lo que limita el consumo de alimentos y reduce el apetito. Al mismo tiempo, los alimentos pasan directamente al intestino delgado, evitando gran parte del estómago y el intestino delgado superior.

En comparación con la manga gástrica, el bypass gástrico tiene una tasa de éxito más alta, ya que los pacientes pierden más peso en promedio. Sin embargo, el bypass gástrico también es más complicado y riesgoso, ya que involucra cambios significativos en la anatomía y fisiología del tracto gastrointestinal.


La manga gástrica es una de las opciones de cirugía bariátrica disponibles, pero no es la única. Cada tipo de cirugía bariátrica tiene sus propias ventajas y desventajas, y es importante considerar cuidadosamente cuál es la mejor opción para cada paciente. Si bien la cirugía bariátrica puede ser una herramienta efectiva para perder peso y tratar la obesidad, también conlleva algunos riesgos y no es una solución milagrosa.

Understanding the Differences between Gastric Sleeve and Gastric Bypass Surgery

Gastric Sleeve and Gastric Bypass Surgery

When dealing with severe obesity, traditional weight loss methods such as regular exercise, diet plans, and weight loss medications may not be effective. Bariatric surgery, including gastric sleeve and gastric bypass, can help those struggling with obesity to lose significant amounts of weight and get their health back on track. Both procedures work by reducing the size of the stomach, but there are differences between them that you should know.

Gastric Sleeve Surgery

Gastric sleeve surgery, also known as vertical sleeve gastrectomy, involves removing a significant part of the stomach, leaving only a small sleeve-shaped stomach. This reduction in stomach size makes you feel full more quickly, and you eat less because you will feel satisfied faster with less food. As a result, you will consume fewer calories and lose weight.

This procedure is typically faster and safer than gastric bypass surgery, and the recovery time is usually much faster. The reduced stomach size can also improve obesity-related conditions such as type 2 diabetes, high cholesterol, and high blood pressure.

Gastric Bypass Surgery

Gastric bypass surgery, also known as Roux-en-Y gastric bypass, involves creating a small stomach pouch and rerouting the small intestine to allow food to bypass some of the stomach and small intestine. This procedure effectively limits the absorption of calories from the food that is consumed, leading to weight loss. Patients will feel full faster, and less food is consumed as a result of reducing stomach size and the rerouting of the small intestine disease.

Due to the more complex nature of the surgery, gastric bypass surgery carries a higher risk of complications such as infection, malnutrition, and vitamin deficiencies than gastric sleeve surgery. However, gastric bypass is the preferred surgery for patients with conditions such as gastroesophageal reflux disease, severe diabetes, or high blood pressure.

Which Procedure is Right for You?

The decision to choose between gastric sleeve and gastric bypass should be made after a thorough discussion with your bariatric surgeon. They will evaluate your medical history, current weight, and lifestyle to determine which procedure is best suited for you.

In general, gastric sleeve surgery is suitable for those with a BMI of 30 and above, while gastric bypass surgery is typically reserved for those with a BMI of 35 or higher who also have conditions such as type 2 diabetes, sleep apnea, or heart disease. Ultimately, the right procedure will depend on your individual health needs and goals.

When considering bariatric surgery, remember that it is not a quick fix, but rather a tool to help you achieve and maintain a healthy weight and reduce your risk of obesity-related health problems. Your success with either procedure will require making significant lifestyle changes such as eating a healthy diet and engaging in regular physical activity.

Talk to your doctor or bariatric surgeon to determine which procedure is the best option for you. With the right program and support, bariatric surgery can be a life-changing decision for those struggling with obesity.
