What Is Transit Bipartition Surgery?

Transit bipartition surgery is a bariatric procedure that creates two separate pathways for food by altering the stomach and small intestine. One portion of the stomach directs food to the small intestine for normal digestion, while the other portion bypasses directly to the distal intestine. This procedure not only limits food intake but also enhances insulin sensitivity, making it highly effective in treating type 2 diabetes and supporting weight loss.

Eliminate Diabetes with Transit Bipartition Surgery

One of the most important benefits of transit bipartition surgery is its ability to help patients with type 2 diabetes achieve remission:

Increase in Insulin Sensitivity:This surgery significantly enhances insulin sensitivity by directing food in a way that stimulates the secretion of the GLP-1 hormone, which helps regulate blood glucose levels. Reduction in Insulin Dependence: Many patients who undergo transit bipartition surgery observe a substantial decrease, or even complete elimination, of their need for insulin injections and other diabetes medications. Long‑Term Diabetes Control: With this procedure, 80–90% of patients achieve remission of type 2 diabetes, enabling them to live without continuous medication or insulin management.

Before Transit Bipartition Surgery – Important Pre‑Operative Instructions

Preparing for a transit bipartition surgery in Istanbul requires following specific steps to achieve a successful outcome:

Medical Evaluation and Consultation:During the initial consultation at ONE CLINIC, our bariatric surgeon will review your medical history, current health status, and diabetes to determine whether you are a suitable candidate for surgery. We will also discuss your weight‑loss goals and the expected outcomes. Pre‑operative Diet: As with other bariatric procedures, a low‑calorie, high‑protein diet for 1–2 weeks before surgery may be required to reduce liver size and make the procedure safer. Strict adherence to this diet will yield the best results. Pre‑operative Fasting: Prior to surgery you will need to abstain from food and drink for 8–12 hours to keep the stomach empty and prepare for the procedure. Quit Smoking and Alcohol: If you smoke, it is crucial to stop at least two weeks before surgery, as smoking can impair healing. Likewise, avoid alcohol in the days leading up to the operation. Transportation and Support: Because the surgery is performed under anesthesia, you should arrange for someone to drive you home and provide assistance during the first few days of recovery.

After your transit bipartition surgery, it is essential to follow the post‑operative care instructions to ensure proper healing and to maximize the benefits of the procedure for both weight loss and diabetes management:

Dietary Progression:Immediately after surgery you will start with a liquid diet, then advance to pureed foods, followed by soft foods, and finally small portions of solid foods. The nutrition specialist at ONE CLINIC will provide you with a detailed plan to follow. Hydration: It is vital to keep your body well‑hydrated by drinking plenty of water throughout the day. Sip water slowly to avoid discomfort and steer clear of sugary or carbonated beverages. Light Activity: Begin walking as soon as possible to promote circulation and prevent blood clots, but avoid heavy lifting and strenuous activities for at least 4–6 weeks. Medications: Follow your physician’s instructions regarding prescribed medications, and, if necessary, take the appropriate vitamins, supplements, or insulin adjustments. Follow‑up Appointments: Regular follow‑up visits at ONE CLINIC will be scheduled to monitor your recovery, track weight‑loss progress, and assess your diabetes status.

Who Is a Suitable Candidate for Transit Bipartition Surgery?

Transit bipartition surgery is designed for patients battling type 2 diabetes and obesity. Ideal candidates include:

Adults Aged 18–65:This surgery is suitable for adults with type 2 diabetes and a BMI (Body Mass Index) of 30 or higher. It is particularly beneficial for those whose diabetes remains uncontrolled despite medication or insulin use. Commitment to Lifestyle Changes: Candidates must be firmly committed to long-term dietary modifications and physical activity to sustain the benefits of the surgery. Good Health Status: Patients should not have any serious health conditions that could hinder recovery or increase surgical risks.

How Much Weight Can You Lose with Transit Bipartition Surgery?

Transit bipartition surgery not only helps manage type 2 diabetes but also promotes significant weight loss:

Expected Weight Loss:Patients typically lose approximately 60–70% of their excess body weight within the first 12–18 months after surgery. The amount of weight loss varies depending on your starting weight and adherence to dietary and lifestyle changes. Sustainable Results: With appropriate postoperative care, patients can maintain long-term weight loss and continue to experience improvements in their overall health.

Anesthesia Used for Transit Bipartition Surgery

At ONE CLINIC, the transit bipartition surgery is performed under general anesthesia:

General Anesthesia:You will be fully unconscious during the procedure and will not experience pain or discomfort. The surgery typically lasts 2-3 hours, depending on the complexity of each case. Postoperative Monitoring: After the procedure, you will be closely monitored in the hospital while recovering from anesthesia. Most patients stay in the hospital for several days before discharge.

Recovery Time for Transit Bipartition Surgery

Recovery from the transit bipartition surgery is relatively rapid, considering its minimally invasive approach:

Hospital Stay:Most patients remain in the hospital for 2–3 days after surgery for observation and initial recovery. Return to Light Activities: You should be able to resume light activities such as walking within 1–2 weeks. Full recovery, including returning to work or more strenuous activities, typically takes 4–6 weeks. Long‑Term Monitoring: Because this surgery significantly impacts your metabolism, you will require ongoing monitoring in the months after the procedure to track diabetes management and weight loss.
