1. What is Sleeve Gastrectomy?

Sleeve gastrectomy is a surgical procedure that involves removing a portion of the stomach, typically about 75%, to create a smaller, sleeve-shaped stomach. This limits the amount of food that can be consumed, leading to weight loss. The remaining portion of the stomach is then stapled closed.

The surgery is usually performed laparoscopically, which means small incisions are made in the abdomen and a small camera is inserted to guide the surgeon during the procedure.

2. Why is Sleeve Gastrectomy Done?

Sleeve gastrectomy is typically recommended for individuals who are severely obese and have been unable to lose weight through diet and exercise. It may also be recommended for individuals who have obesity-related health problems, such as type 2 diabetes, high blood pressure, or sleep apnea.

Sleeve gastrectomy can also be used as a first step before more invasive weight loss surgeries, such as gastric bypass or duodenal switch.

3. Who is a Good Candidate for Sleeve Gastrectomy?

Sleeve gastrectomy may be a good option for individuals with a body mass index (BMI) of 40 or higher, or for those with a BMI of 35 or higher with obesity-related health problems. Candidates for sleeve gastrectomy should also have tried and failed to lose weight through other methods, such as diet and exercise.

4. What are the Risks of Sleeve Gastrectomy Surgery?

Like all surgical procedures, sleeve gastrectomy carries some risks. These risks can include bleeding, infection, blood clots, and reactions to anesthesia. Additionally, some patients may experience complications such as leaking from the staple line or blockages in the digestive tract.

5. How is Sleeve Gastrectomy Surgery Performed?

Sleeve gastrectomy is usually performed laparoscopically, which means small incisions are made in the abdomen and a small camera is inserted to guide the surgeon during the procedure. The surgeon then removes a portion of the stomach and staples the remaining portion closed.

The procedure usually takes about 1-2 hours, and patients typically stay in the hospital for 1-2 days after the surgery.

6. What Should Be Done After Sleeve Gastrectomy?

After sleeve gastrectomy, patients will need to follow a strict diet and exercise regimen to ensure the best results. Initially, patients will be on a liquid diet for the first week or two, before slowly transitioning to soft foods and then solid foods over the course of several weeks. Patients will also need to avoid certain foods and beverages, such as alcohol, carbonated drinks, and high-fat or high-sugar foods.

In addition to following a healthy diet, patients will need to incorporate regular exercise into their routine to achieve and maintain weight loss. A physician or a registered dietitian can provide guidance on the appropriate diet and exercise plan after sleeve gastrectomy.

7. How to Prepare for Sleeve Gastrectomy?

Before undergoing sleeve gastrectomy, patients will need to undergo a thorough evaluation to ensure they are good candidates for the procedure. This may include blood tests, imaging tests, and consultations with various specialists, such as a nutritionist and a psychologist.

In the weeks leading up to the surgery, patients may be advised to make lifestyle changes to improve their overall health and reduce the risk of complications. This may include quitting smoking, losing weight, and increasing physical activity.

8. What are the Results of Sleeve Gastrectomy?

Sleeve gastrectomy can result in significant weight loss, with patients typically losing 50-70% of their excess weight within the first two years after surgery. This can lead to significant improvements in obesity-related health problems, such as type 2 diabetes, high blood pressure, and sleep apnea.

However, it is important to note that weight loss is not guaranteed, and individual results may vary. Additionally, patients will need to commit to a healthy lifestyle and regular follow-up appointments with their healthcare team to ensure long-term success.

9. Comparing Sleeve Gastrectomy with Other Weight Loss Surgeries

Sleeve gastrectomy is one of several surgical options for weight loss, including gastric bypass and duodenal switch. Each procedure has its own unique benefits and risks, and the best option for an individual will depend on their specific health history and weight loss goals.
