What Is Ileal Interposition Surgery?

Ileal interposition surgery is a metabolic and bariatric procedure in which a segment of the small intestine (the ileum) is positioned closer to the stomach. This reconfiguration alters the way food passes through the digestive system, triggering hormonal changes that increase insulin sensitivity and improve blood‑glucose control. The surgery is highly effective in managing type 2 diabetes and achieving significant weight loss.

Eliminate Diabetes with Ileal Interposition Surgery

One of the most important benefits of ileal interposition surgery is its ability to help patients with type 2 diabetes manage their dependence on insulin, or even eliminate the need for insulin altogether:

Increased Insulin SensitivityRepositioning a segment of the small intestine increases the secretion of GLP-1 hormone, which plays a critical role in blood glucose control and enhancing insulin sensitivity.
Reduced Insulin DependenceMany patients undergoing ileal interposition surgery experience a significant reduction or complete cessation of insulin therapy or other diabetes medications.
Long-Term Diabetes RemissionStudies show that 70-80% of patients achieve long-term remission of type 2 diabetes, allowing them to live without daily medication or insulin injections.

Before Ileal Interposition Surgery – Important Preoperative Instructions

Preparation for ileal interposition surgery is crucial to achieve a successful outcome. Here’s how you should prepare:

Postoperative care is essential for a smooth recovery and to obtain the best results from ileal interposition surgery in Istanbul:

Consultation and Medical EvaluationDuring your consultation at ONE CLINIC, our expert surgeon will assess your medical history, diabetes status, and overall health to determine if you are a suitable candidate for ileal interposition surgery. Your weight‑loss goals and expected outcomes will also be discussed.
Preoperative DietOne to two weeks before surgery, a low‑calorie, high‑protein diet may be required to reduce liver size. This helps make the procedure safer and more effective.
Preoperative FastingYou will need to fast for 8–12 hours before surgery to ensure your stomach is empty. All food and drink should be avoided.
Avoid Smoking and AlcoholSmoking can impede healing and increase surgical risks. You should quit smoking at least two weeks before the operation and avoid alcohol consumption in the days leading up to the procedure.
Arrange Transportation and SupportBecause the surgery requires general anesthesia, you will need someone to drive you home and to assist you during the first few days of recovery.
Dietary ModificationsImmediately after surgery you will begin with a liquid diet, then progress to pureed foods, soft foods, and finally small, healthy meals. Your nutrition specialist at ONE CLINIC will provide a personalized diet plan.
HydrationAfter surgery, it is important to drink water throughout the day to prevent dehydration. You should avoid sugary and carbonated beverages, as they can irritate the stomach and intestines.
Light ActivityWalking and light movement are recommended as soon as possible to promote blood circulation and prevent complications. You should avoid strenuous activities for at least 4–6 weeks.
Follow Medication InstructionsYour medication regimen will be adjusted after surgery based on your diabetes status. Depending on your progress, your doctor may reduce or completely discontinue your insulin use.
Follow-Up AppointmentsRegular follow-up appointments at ONE CLINIC are essential to monitor your recovery, assess diabetes control, and track your weight loss progress.
