Gastric sleeve surgery, also known as Vertical Sleeve Gastrectomy, involves removing approximately 75–80% of the stomach, leaving behind a sleeve-shaped or banana-sized stomach.

This procedure helps patients feel full much faster, facilitating significant weight loss. Typically recommended for individuals with a body mass index (BMI) of at least 40, gastric sleeve surgery is a critical intervention for those struggling with severe obesity. However, post-surgery, maintaining a regimen of exercise and healthy eating remains essential.

Benefits of Gastric Sleeve Surgery

• Improved Quality of Life: Many patients experience a significant enhancement in their overall well-being and daily functioning.
• Substantial Weight Loss: Patients typically lose about 60-70% of their excess weight within the first year after surgery.
• Reduced Obesity-Related Health Issues: The surgery can prevent or alleviate conditions such as sleep apnea, type 2 diabetes, hypertension, and joint pain.
• Decreased Appetite: Patients often experience a dramatic reduction in their desire to eat.
• Reduced Hunger Sensation: The surgery lowers ghrelin hormone levels, decreasing hunger sensations.

Gastric sleeve surgery in Turkey is known for being more affordable than in many other countries. The cost typically ranges between €2600, which can be significantly lower than in Western Europe or North America, where the surgery can cost between €10,000 and €20,000.

Factors Influencing the Cost

1. Hospital and Clinic Reputation: Prestigious hospitals with high success rates and advanced facilities may charge more.
2. Surgeon’s Experience: Highly experienced surgeons with specialized expertise often have higher fees.
3. Inclusions in the Package: Some packages may include additional services such as pre-operative tests, post-operative care, accommodation, and airport transfers.
4. Location of the Hospital: Hospitals in major cities like Istanbul may have different pricing than those in smaller towns.
5. Medical Technology and Equipment: Using the latest medical technology and equipment can impact costs.
6. Post-Surgery Follow-up and Support: Comprehensive follow-up care and support services can add to the cost.
7. Patient’s Health Condition: The patient’s overall health and any underlying conditions can affect the complexity and cost of the surgery.
8. Insurance Coverage: Some health insurance plans may cover part of the surgery costs, influencing the out-of-pocket expenses for the patient.

Understanding these factors can help potential patients budget accordingly and choose the best option for their needs and financial situation.

Gastric sleeve surgery boasts a high success rate and patient satisfaction rate, making it a popular choice for weight loss surgery.

Success Rate

• Weight Loss: Patients typically lose 60-70% of their excess weight within the first year post-surgery. Long-term studies show that many patients maintain significant weight loss, losing around 50-60% of their excess weight five years after surgery.
• Health Improvement: The surgery effectively resolves or improves obesity-related health issues. For example, about 75-85% of patients experience remission of type 2 diabetes, and around 80% see improvement or resolution of sleep apnea.

Patient Satisfaction Rate

• Quality of Life: Most patients report a substantial improvement in their quality of life. Studies indicate that around 85-90% of patients are satisfied with their results, citing increased mobility, better mental health, and enhanced overall well-being.
• Sustained Results: Many patients express satisfaction with the long-term results, noting that they can maintain their weight loss and enjoy a healthier lifestyle.

This detailed timeline outlines the typical recovery and long-term outcomes for gastric sleeve surgery, highlighting the significant positive impact on weight and health over time.

Weight loss surgeries, also known as bariatric surgeries, are designed to help individuals with severe obesity lose weight and improve their health. Here are the most common types of weight loss surgeries:

Gastric Sleeve (Vertical Sleeve Gastrectomy)

• Procedure: Approximately 75-80% of the stomach is removed, leaving a sleeve-shaped stomach.
• Mechanism: Reduces the stomach’s capacity, leading to early satiety and decreased hunger.
• Benefits: Significant weight loss improvement in obesity-related conditions such as diabetes and hypertension.

Gastric Bypass (Roux-en-Y Gastric Bypass)

• Procedure: The stomach is divided into a small upper pouch and a larger lower pouch, and the small intestine is rearranged to connect to both.
• Mechanism: Reduces stomach size and alters the digestive process, leading to decreased calorie absorption.
• Benefits: Substantial weight loss, effective in resolving type 2 diabetes, and improvement in other obesity-related conditions.

Adjustable Gastric Banding (Lap-Band)

• Procedure: An inflatable band is placed around the upper part of the stomach, creating a small pouch above the band.
• Mechanism: Restricts food intake and slows digestion, promoting a feeling of fullness with less food.
• Benefits: Less invasive, reversible, and adjustable based on the patient’s needs.

Gastric Balloon

• Procedure: A deflated balloon is inserted into the stomach via the mouth and then inflated.
• Mechanism: Takes up space in the stomach, reducing the amount of food the stomach can hold and promoting a feeling of fullness.
• Benefits: Non-surgical, temporary, and can be removed after achieving weight loss goals.

Each type of weight loss surgery has its advantages and potential risks. The choice of surgery depends on various factors, including the patient’s health condition, weight loss goals, and the surgeon’s recommendation.

Consulting with a healthcare provider is essential to determine the most suitable option for achieving long-term weight loss and health improvement.

Surgery

Recovery

• Hospital Stay: Most patients stay in the hospital for 2-3 days following the surgery for monitoring and initial recovery.
• Pain Management: Pain and discomfort are managed with medications the healthcare team prescribes.
• Dietary Progression: The recovery diet starts with clear liquids and progresses to full liquids, pureed foods, and soft foods over the next few weeks.
• Activity: Patients are encouraged to engage in light activities, such as walking, soon after surgery to promote circulation and prevent blood clots.

Follow-Up

• Postoperative Appointments: Regular follow-up visits with the surgeon are essential to monitor healing, check for complications, and track weight loss progress.
