Gastric Sleeve

What is a Gastric Sleeve?

Gastric sleeve surgery, also known as sleeve gastrectomy, is a surgical weight loss procedure that involves the removal of a large portion of the stomach to create a smaller, sleeve-shaped pouch.  Gastric sleeve surgery is typically performed under general anesthesia and usually takes around 1-2 hours to complete. Unlike some other weight loss procedures, such as gastric bypass, gastric sleeve surgery does not involve rerouting or bypassing any part of the digestive tract. Instead, it primarily restricts the amount of food that can be consumed, thereby promoting weight loss.

Understanding Gastric Sleeves

One of the key advantages of gastric sleeve surgery is that it not only reduces stomach volume but also removes a portion of the stomach that produces the hunger-stimulating hormone ghrelin. As a result, patients often experience a decrease in appetite and cravings following the procedure, which can contribute to successful long-term weight loss. Gastric sleeve surgery is typically recommended for individuals with a body mass index (BMI) of 40 or higher (severe obesity) or a BMI of 35-39.9 (obesity) with obesity-related health conditions such as type 2 diabetes, high blood pressure, or sleep apnea. It may also be considered for individuals with a lower BMI who have tried and failed to achieve significant weight loss through non-surgical methods.

Most healthcare providers use BMI to assess eligibility for weight loss surgery. Typically, individuals with a BMI of 40 or higher (severe obesity) or a BMI of 35-39.9 (obesity) with significant obesity-related health conditions like type 2 diabetes or high blood pressure may qualify.

Post-Gastric Bypass Recovery Tips

After undergoing gastric bypass surgery, patients must adhere to certain guidelines and instructions:

  • Avoid eating immediately after the operation; only consume fluids initially. Progress to pureed, soft, and then solid complex foods gradually.
  • Take prescribed vitamin and mineral supplements, including iron, calcium, and vitamin B12.
  • Refrain from strenuous activities or heavy lifting for at least one month post-operation.
  • Avoid smoking for at least two weeks to a month following the procedure.
  • To maintain weight loss and achieve long-term success, adhere to a balanced diet and engage in regular exercise.

Post-surgery, the smaller stomach pouch reduces calorie and nutrient absorption, necessitating vitamin and immune system supplements prescribed by our surgeon for long-term use.

Addressing Your Concerns

Gastric sleeve surgery involves the surgical removal of a portion of the stomach to create a smaller, sleeve-shaped pouch. This reduces the stomach's capacity and limits the amount of food that can be consumed, leading to significant weight loss. Unlike gastric balloon insertion, gastric sleeve surgery is a permanent procedure that alters the anatomy of the digestive system.  It is typically recommended for individuals with a higher body mass index (BMI) or those who have obesity-related health conditions such as type 2 diabetes. While gastric sleeve surgery is more invasive than gastric balloon insertion, it offers the potential for substantial and sustained weight loss outcomes.

Nevertheless, as with any surgical procedure, there are risks involved, including the potential for complications such as infection, bleeding, and gastrointestinal issues. In conclusion, gastric sleeve surgery is a more comprehensive approach to weight loss management, providing long-term benefits for eligible individuals seeking significant and lasting results.

Before & Afters

Frequently Asked Questions

How much weight can I expect to lose after gastric sleeve surgery?

Weight loss outcomes vary for each individual and depend on factors such as starting weight, adherence to dietary and lifestyle changes, and overall health. On average, patients can expect to lose approximately 60-70% of their excess body weight within the first year after surgery, with continued weight loss over time.

What dietary changes are necessary after gastric sleeve surgery?

After gastric sleeve surgery, patients are typically advised to follow a strict diet progression, starting with clear liquids and gradually advancing to pureed foods, soft foods, and eventually solid foods. It's essential to consume small, frequent meals and focus on protein-rich foods while avoiding sugary or high-fat foods to support weight loss and prevent complications.

Will I need to take supplements after gastric sleeve surgery?

Gastric sleeve surgery can affect nutrient absorption, so patients are often required to take vitamin and mineral supplements, including multivitamins, calcium, vitamin D, vitamin B12, and iron, to prevent nutritional deficiencies. Regular monitoring of nutrient levels through blood tests is essential to ensure optimal health.

What is the recovery process like after gastric sleeve surgery?

Recovery from gastric sleeve surgery involves several stages, including a liquid diet, gradual reintroduction of solid foods, and regular follow-up appointments with the surgical team. Patients typically experience some discomfort, fatigue, and changes in eating habits during the initial recovery period but can gradually resume normal activities within a few weeks.

Are there risks or complications associated with gastric sleeve surgery?

Like any surgical procedure, gastric sleeve surgery carries risks and potential complications, including infection, bleeding, blood clots, leaks at the staple line, nutritional deficiencies, and gastrointestinal issues such as acid reflux or dumping syndrome. It's essential for patients to follow post-operative instructions and attend regular follow-up appointments to monitor for complications and ensure optimal recovery.

Who is a good candidate for gastric sleeve surgery?

Good candidates for gastric sleeve surgery are individuals with a body mass index (BMI) of 40 or higher (severe obesity) or a BMI of 35-39.9 (obesity) with obesity-related health conditions such as type 2 diabetes, high blood pressure, or sleep apnea. Candidates should also have tried and failed to lose weight through non-surgical methods.

Can I regain weight after gastric sleeve surgery?

While gastric sleeve surgery can lead to significant weight loss, some patients may experience weight regain over time due to factors such as poor adherence to dietary and lifestyle recommendations, changes in eating habits, or physiological changes. Regular follow-up appointments with the surgical team and ongoing support are essential for long-term weight management and success.

Can I become pregnant after gastric sleeve surgery?

While pregnancy after gastric sleeve surgery is possible, it's generally recommended to wait at least 12-18 months after surgery and ensure weight loss has stabilized before attempting to conceive. Pregnancy following bariatric surgery requires careful monitoring by healthcare providers to ensure adequate nutrition and healthy fetal development.
