Gastric Sleeve Surgery

What Is Sleeve Gastrectomy Surgery?

Sleeve gastrectomy, commonly known as gastric sleeve surgery, is one of the most effective and widely performed bariatric procedures for treating obesity and obesity-related health conditions. The procedure helps patients achieve significant and long-term weight loss by reducing the size of the stomach, allowing them to feel full sooner and consume less food.

In addition to promoting weight loss, sleeve gastrectomy can significantly improve or even resolve obesity-related conditions such as type 2 diabetes, high blood pressure, sleep apnea, high cholesterol, and cardiovascular disease, leading to better overall health and quality of life.

Who Is a Candidate for Sleeve Gastrectomy?

A bariatric surgeon may recommend sleeve gastrectomy for individuals who:

• Have obesity or severe obesity.

• Have been unable to achieve sustained weight loss through diet and exercise alone.

• Suffer from obesity-related conditions such as diabetes, hypertension, or sleep apnea.

• Experience limitations in daily activities or quality of life due to excess weight.

How Is Sleeve Gastrectomy Performed?

Sleeve gastrectomy is typically performed using minimally invasive laparoscopic surgery through several small abdominal incisions.

During the procedure, the surgeon:

• Removes approximately 70% to 80% of the stomach.

• Creates a narrow, sleeve-shaped stomach.

• Preserves the normal pathway of the digestive system without rerouting the intestines.

The surgery usually takes between one and two hours, depending on the patient's condition and surgical complexity.

Benefits of Sleeve Gastrectomy

Sleeve gastrectomy offers numerous health benefits, including:

• Significant and sustainable weight loss

• Reduced appetite and hunger

• Improvement or remission of type 2 diabetes

• Lower blood pressure and cholesterol levels

• Improvement in sleep apnea symptoms

• Increased mobility and physical activity

• Enhanced quality of life and self-confidence

• Reduced risk of obesity-related cardiovascular disease

Recovery After Sleeve Gastrectomy

Most patients can expect to:

• Leave the hospital within one to two days after surgery.

• Return to light daily activities within a short period.

• Follow a structured dietary progression from liquids to soft foods and eventually regular healthy meals.

• Gradually increase physical activity according to their surgeon's recommendations.

Regular follow-up with the bariatric team and a nutrition specialist is essential for achieving optimal long-term results.

Risks and Potential Complications

Like any surgical procedure, sleeve gastrectomy carries certain risks, including:

• Bleeding

• Infection

• Blood clots

• Staple line leakage

• Gastroesophageal reflux disease (GERD)

• Vitamin and mineral deficiencies

• Anesthesia-related complications

These complications are relatively uncommon when the procedure is performed by an experienced bariatric surgery team and appropriate postoperative care is followed.

Success Rate of Sleeve Gastrectomy

Sleeve gastrectomy is considered one of the most successful bariatric procedures available today. Most patients achieve substantial excess weight loss and experience significant improvement in obesity-related health conditions.

With long-term commitment to healthy eating habits, regular exercise, and medical follow-up, sleeve gastrectomy can provide lasting weight management and significantly improve overall health, longevity, and quality of life.

Symptoms of Severe Obesity:

• Excessive body weight (BMI 35+ with health conditions or BMI 40+).
• Difficulty in mobility and daily activities.
• Breathlessness and fatigue.
• Joint pain due to excess weight.
• Increased hunger and difficulty controlling appetite.

Causes of Severe Obesity:

• Genetics – Family history of obesity.
• Poor diet – High-calorie, processed, and sugary food intake.
• Sedentary lifestyle – Lack of physical activity.
• Hormonal imbalances – Conditions like hypothyroidism or PCOS.
• Medical conditions – Diabetes, sleep apnea, heart disease.

To determine eligibility for gastric sleeve surgery, doctors may conduct:

• BMI Calculation – To assess obesity severity.
• Medical History Review – Identifying weight-related health issues.
• Blood Tests – Checking for diabetes, cholesterol levels, and deficiencies.
• Imaging Tests – Stomach and digestive system evaluation.
• Psychological Assessment – Ensuring mental readiness for lifestyle changes.

Treatment (Gastric Sleeve Surgery Process):

1. Pre-Surgery Preparation:

   • Nutritional counseling and pre-operative weight loss.
   • Medical evaluations and lab tests.
   • Dietary changes to reduce liver size before surgery.

2. Surgery (Laparoscopic Sleeve Gastrectomy):

   • Minimally invasive approach (small incisions, shorter recovery).
   • Stapling and removing 75-80% of the stomach.
   • No intestine rerouting, unlike gastric bypass.

3. Post-Surgery Recovery & Lifestyle Changes:

   • Hospital stay of 1-3 days.
   • Liquid diet for 2-3 weeks, then gradual food reintroduction.
   • Vitamin & mineral supplementation to prevent deficiencies.
   • Regular exercise and lifelong dietary modifications.
