Obesity is a growing epidemic in the United States, with around 40% of adults classified as obese, according to the Food Research and Action Center. For those struggling with severe obesity, weight-loss surgery may be a viable option. Two of the most common weight-loss surgeries are gastric bypass and gastric sleeve. While both procedures can lead to significant weight loss, they differ in their approach and benefits. In this article, we will explore the differences and benefits of gastric bypass and gastric sleeve surgeries.

¿Qué es la cirugía de bypass gástrico?

Gastric bypass surgery, also known as Roux-en-Y gastric bypass, is a surgical procedure that involves creating a small pouch at the top of the stomach and connecting it directly to the small intestine. This reduces the size of the stomach and bypasses a portion of the small intestine, limiting the amount of food that can be consumed and absorbed.

Gastric bypass surgery requirements

Before undergoing gastric bypass surgery, patients must meet certain requirements. These may include:

  • A body mass index (BMI) of 40 or higher
  • A BMI of 35 or higher with obesity-related health conditions
  • Un historial de intentos fallidos de pérdida de peso mediante dieta y ejercicio.
  • A commitment to lifestyle changes and follow-up appointments

¿Qué es la cirugía de manga gástrica?

Gastric sleeve surgery, also known as sleeve gastrectomy, involves removing a large portion of the stomach, leaving a small, banana-shaped pouch. This reduces the size of the stomach and limits the amount of food that can be consumed.

Gastric sleeve surgery requirements

The requirements for gastric sleeve surgery are similar to those for gastric bypass surgery. Patients must have a BMI of 40 or higher, or a BMI of 35 or higher with obesity-related health conditions. They must also have a history of failed weight-loss attempts and be committed to lifestyle changes and follow-up appointments.

Beneficios de la Cirugía Bariátrica

There can be many benefits of bariatric surgery on both your physical health and your mental health. Ongoing trends in this space, including the prevalence of robotic and laparoscopic surgery, are causing weight-loss surgery to be even less invasive than ever before. Other benefits of weight-loss surgery can include:

Benefits of gastric bypass surgery

Gastric bypass is when a surgeon detaches the top section of your stomach and seals it shut to create a small pouch. The pouch is then attached to the lower part of the small intestine to bypass the larger part of the stomach.

The small intestine is still attached to the large part of the stomach, which allows the larger part of the stomach to receive blood and remain in place. Some of the benefits of this type of surgery include:

  • Significant Weight Loss: One of the main benefits of gastric bypass surgery is significant weight loss. On average, patients can expect to lose 60-80% of their excess body weight within the first year after surgery, according to the Mayo Clinic. This can lead to improved overall health and a reduced risk of obesity-related health conditions.
  • Improved Health: Gastric bypass surgery has been shown to improve or resolve obesity-related health conditions such as type 2 diabetes, high blood pressure, and sleep apnea. This can lead to a better quality of life and a reduced need for medication.
  • Long-Term Results: Studies have shown that gastric bypass surgery can lead to long-term weight loss and health improvements. This is due to the permanent changes made to the digestive system, which limit the amount of food that can be consumed and absorbed.

Gastric sleeve is a restrictive weight loss surgery that reduces the overall  size of the stomach. The small intestine isn’t operated on in gastric sleeve surgery, only the stomach. Some of the benefits of this type of surgery include:

  • Significant Weight Loss: Similar to gastric bypass surgery, gastric sleeve surgery can also lead to significant weight loss. On average, patients can expect to lose 50-70% of their excess body weight within the first year after surgery, according to the National Institutes of Health (NIH).
  • Reduced Risk of Complications: Gastric sleeve surgery is a less invasive procedure compared to gastric bypass surgery, which means there is a lower risk of complications. This can be beneficial for patients who may not be suitable candidates for more invasive surgeries.
  • Improved Health: Gastric sleeve surgery has been shown to improve or resolve obesity-related health conditions, similar to gastric bypass surgery. This can lead to a better quality of life and a reduced need for medication.

Gastric Bypass vs. Gastric Sleeve: Which Is Right for You?

Both gastric bypass and gastric sleeve surgeries have their own unique benefits. The best option for you will depend on your individual needs and preferences. It is important to consult with a qualified bariatric surgeon to determine which procedure is right for you.

Before and after bariatric surgery

Before undergoing any weight-loss surgery, it is important to understand the potential risks and benefits. It is also important to have a clear understanding of the lifestyle changes that will be necessary after surgery. This may include changes in diet, exercise, and follow-up appointments.
