Gastric Sleeve at ONE CLINIC


Gastric sleeve surgery, also known as sleeve gastrectomy, is a highly effective weight loss procedure that helps patients lose significant weight by reducing the size of the stomach. At ONE CLINIC, located in Istanbul, Turkey, we specialize in this minimally invasive surgery, providing patients with a safe, long-term solution for weight management.

What is Gastric Sleeve Surgery?

Gastric sleeve surgery involves removing a portion of the stomach, leaving behind a smaller, tube-shaped stomach that limits the amount of food you can eat, thus helping you feel full more quickly. This procedure is ideal for individuals who are struggling with obesity and want to achieve sustainable weight loss.

Before Your Gastric Sleeve Surgery – Key Pre-Operative Instructions

Proper preparation is crucial to ensuring a successful gastric sleeve surgery and smooth recovery. Here’s what you need to do before the operation:

  1. Consultation and Medical Evaluation: During your consultation at ONE CLINIC, our expert bariatric surgeon will assess your medical history, current health, and weight loss goals to ensure you are a suitable candidate for gastric sleeve surgery. We will also discuss the expected outcomes and potential risks.
  2. Pre-Operative Diet: You may be required to follow a special pre-operative diet, typically high in protein and low in carbohydrates, to reduce the size of your liver and make the surgery safer. This diet typically starts 1-2 weeks before your surgery.
  3. Fasting Before Surgery: You will need to fast (no food or drink) for at least 8-12 hours before the procedure, as instructed by your surgeon. This ensures your stomach is empty for the operation.
  4. Avoid Smoking and Alcohol: Stop smoking at least two weeks before surgery, as smoking can interfere with healing and increase the risk of complications. Similarly, avoid alcohol consumption in the days leading up to the surgery.
  5. Arrange Transportation and Assistance: Since you will be under anesthesia during the procedure, arrange for someone to drive you home and assist with daily tasks during the first few days of recovery.

After Your Gastric Sleeve Surgery – Post-Operative Care

Proper aftercare is key to ensuring the success of your gastric sleeve surgery in Istanbul and achieving your weight loss goals. Here are the post-operative guidelines:

  1. Dietary Transition: After surgery, you will follow a liquid diet for the first week, gradually transitioning to soft foods and, later, solid foods. Your nutritionist at ONE CLINIC will provide you with a detailed post-operative diet plan to help your body adjust to its new, smaller stomach.
  2. Hydration: It’s important to stay hydrated, drinking plenty of water throughout the day. Sip water slowly to avoid overfilling your stomach and prevent nausea.
  3. Avoid Strenuous Activity: For the first 4-6 weeks after surgery, avoid any strenuous physical activities. Walking and light exercises are encouraged to promote circulation and aid in the healing process.
  4. Follow-Up Appointments: Regular follow-up appointments at ONE CLINIC will be scheduled to monitor your recovery and weight loss progress. Our team will provide guidance and support during your entire journey.
  5. Long-Term Dietary Changes: Adhering to a healthy, balanced diet is essential for long-term success. High-protein, low-sugar, and nutrient-dense foods will be recommended to maximize weight loss and overall health.

Healing Time After Gastric Sleeve Surgery

Healing time for gastric sleeve surgery is relatively short compared to other weight loss surgeries:

Hospital Stay: Most patients stay in the hospital for 2-3 days after the surgery for monitoring and recovery.

Return to Normal Activities: You can typically return to light activities within 1-2 weeks. Full recovery, including returning to strenuous activities or exercise, usually takes about 4-6 weeks.

Long-Term Healing: Your stomach will take several weeks to adjust to its new size. It’s essential to follow dietary and activity restrictions to ensure proper healing and avoid complications.


Who is Eligible for Gastric Sleeve Surgery?

Ideal candidates for gastric sleeve surgery in Istanbul include:

Adults aged 18-65: This procedure is suitable for adults with a BMI (Body Mass Index) of 35 or higher, or those with a BMI of 30+ who have obesity-related health issues such as type 2 diabetes or hypertension.

Committed to Lifestyle Changes: Candidates should be ready to make long-term changes to their diet and lifestyle to maintain weight loss after the surgery.

Good Health: Patients should be in overall good health, without any significant medical conditions that could interfere with healing or increase surgical risks.




How Much Weight Can You Lose with Gastric Sleeve Surgery?

Most patients lose 60-70% of their excess body weight within the first year after gastric sleeve surgery. This can translate to a significant weight loss depending on your starting weight. Long-term success depends on adhering to the dietary and lifestyle changes recommended by your medical team at ONE CLINIC.



Can Gastric Sleeve Surgery Be Done Without Scarring?

Gastric sleeve surgery is typically performed using a minimally invasive laparoscopic technique, which involves small incisions in the abdomen:

  • Minimize Scarring: The small incisions, usually 1-2 cm in size, leave minimal scarring that fades over time. With proper post-operative care, such as keeping the incisions clean and following your surgeon’s instructions, scarring will be minimal and often not noticeable after a few months.
  • Healing Process: The incisions typically heal within 2-3 weeks, and scarring fades over the next several months. Your surgeon may recommend scar-reducing treatments to further minimize their appearance.

Anesthesia Options for Gastric Sleeve Surgery

Gastric sleeve surgery at ONE CLINIC in Istanbul is performed under general anesthesia:

  1. General Anesthesia: You will be fully asleep during the surgery, ensuring that you do not feel any pain or discomfort during the procedure. The surgery typically lasts about 1-2 hours, after which you will be taken to a recovery room to awaken from anesthesia.
  2. Monitoring and Safety: Our experienced anesthesiologists will monitor your vital signs throughout the procedure to ensure your safety and comfort.
