I&#8217;m Dr. Crist\u00f3bal Garza, a bariatric and metabolic surgeon in Piedras Negras, Coahuila, just 15 minutes from Eagle Pass, Texas. In this article I want to explain, in plain language but grounded in the science, one of the most promising metabolic operations available today: <strong>transit bipartition<\/strong>, and what the research tells us about its effect on type 2 diabetes remission.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is transit bipartition?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Transit bipartition<\/strong> (often written as sleeve gastrectomy with transit bipartition, or SG-TB) is a metabolic surgery first described by Dr. Sergio Santoro and colleagues in Brazil, with the laparoscopic technique published around 2012. It combines two ideas in a single operation: a sleeve gastrectomy, which reduces the size of the stomach, and a \u00abbipartition,\u00bb which reroutes part of the food stream directly to the last portion of the small intestine.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In practical terms, after the sleeve is created, the surgeon connects the lower part of the stomach to the ileum (the final segment of the small intestine). This leaves the stomach with two exits: one that follows the normal path through the duodenum, and one that sends food on a shortcut to the ileum. Most of the food preferentially takes the shortcut, while a portion still travels the natural route.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why preserving the duodenum matters<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">This is one of the features that makes transit bipartition stand out. Unlike older procedures such as the biliopancreatic diversion with duodenal switch, which completely exclude the duodenum, transit bipartition <em>keeps the duodenum in the food stream<\/em>. Research suggests this design helps in two important ways: it tends to minimize the malabsorption and nutritional deficiencies associated with more aggressive bypass operations, and it preserves endoscopic access to the duodenum and the bile ducts \u2014 which can matter years later if you ever need a gastroscopy or a procedure on the bile duct.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In other words, the operation aims to capture much of the powerful metabolic effect seen with bypass surgeries while reducing some of their long-term nutritional trade-offs. As with any procedure, this balance is something we evaluate carefully for each patient.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How transit bipartition affects type 2 diabetes<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">To understand why this surgery influences diabetes, it helps to know the \u00abforegut\u2013hindgut\u00bb idea that researchers use to explain metabolic surgery. The theory suggests that a modern diet high in refined, high-glycemic foods overstimulates the upper gut (the foregut) and understimulates the lower gut (the hindgut), contributing to the hormonal imbalance behind metabolic syndrome and type 2 diabetes.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">The incretin effect<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">By delivering food more quickly to the ileum, transit bipartition stimulates the lower gut to release hormones called <strong>incretins<\/strong> \u2014 most notably GLP-1 (glucagon-like peptide-1) and PYY. These are the same hormone pathways targeted by today&#8217;s popular diabetes and weight-loss medications. Studies indicate that after this type of rerouting, the body&#8217;s postprandial (after-meal) GLP-1 and PYY rise substantially, which is associated with better insulin secretion, improved insulin sensitivity, and reduced appetite. Importantly, much of this metabolic benefit appears to happen relatively quickly and partly independently of weight loss \u2014 one reason metabolic surgery is taken so seriously as a diabetes treatment, not just a weight treatment.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What does the research say about diabetes remission?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The published evidence on transit bipartition and type 2 diabetes is encouraging, though it is important to read it with realistic expectations. Across several studies, reported type 2 diabetes remission rates after sleeve gastrectomy with transit bipartition have been high \u2014 often cited in the range of roughly 80% to 98%, depending on how remission is defined and how long patients are followed.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>In one of the larger series, a study of 355 patients found that about 79% maintained complete remission of type 2 diabetes at two years, with benefits seen regardless of how long or how severe their diabetes had been before surgery.<\/li>\n\n\n\n<li>A comparison study reported diabetes remission in roughly 90% of transit bipartition patients versus 88% of duodenal switch patients at one year \u2014 comparable results, but with the duodenum-preserving advantages of bipartition.<\/li>\n\n\n\n<li>A three-year follow-up analysis reported diabetes remission in about 84% of patients.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">I want to be candid here: \u00abremission\u00bb does not mean a guaranteed cure, and results vary from person to person. Factors such as how long you have had diabetes, your insulin use, your pancreatic function, and your commitment to follow-up all influence the outcome. Some people achieve complete remission; others see a major improvement that still requires less medication. This is exactly why an individualized evaluation matters.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Who might be a candidate?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Transit bipartition is generally considered for adults with obesity and type 2 diabetes, particularly those whose diabetes has been difficult to control or who are looking for a strong metabolic effect. It may also be discussed for patients who have already had a sleeve gastrectomy and need a \u00absecond stage\u00bb to improve weight loss or diabetes control. As always, candidacy depends on a full medical evaluation \u2014 your BMI, your diabetes history, your nutritional status, and your overall health.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you would like to know whether you are a candidate, you can <a href=\"\/free-consultation\/\">schedule your free consultation here<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">A team approach, not just an operation<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Obesity and type 2 diabetes are diseases, not a lack of willpower, and they deserve serious, respectful care. A successful outcome is never just about the surgery itself. In our practice, the operation is one part of a multidisciplinary process that includes a nutritionist, who helps you build sustainable eating habits, and a psychologist, who supports the behavioral side of change. Lifelong vitamin and mineral monitoring, and regular follow-up, are part of staying healthy after any metabolic procedure. Lasting results come from this teamwork \u2014 surgeon, nutritionist, psychologist, and you, walking the path together.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Take the next step<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If you live with obesity and type 2 diabetes and want to understand whether transit bipartition could be right for you, I would be glad to guide you with clear, honest information. <strong>Schedule your free consultation<\/strong> at our office in the Cl\u00ednica de Especialistas, office 302, in Piedras Negras, Coahuila \u2014 an easy crossing from Eagle Pass, Texas \u2014 or message me directly on WhatsApp at <strong>+52 878 115 7532<\/strong>.

Transit bipartition&#8217;s main distinction is that it preserves the duodenum, which research suggests may reduce certain nutritional deficiencies and keeps endoscopic access to the upper digestive tract. The best choice depends on your individual case and should be decided with your surgeon.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How quickly can diabetes improve after surgery?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Many patients notice improvement in blood sugar control within days to weeks, before significant weight loss occurs. Research attributes this early effect partly to changes in gut hormones such as GLP-1. The timeline and degree of improvement vary from person to person.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Does diabetes remission mean I am cured?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Not exactly. Remission means blood sugar levels return to a healthy range, often without medication, but it is not a guaranteed permanent cure. Diabetes can return, especially with significant weight regain. Ongoing follow-up and healthy habits are essential to maintain the benefit.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What are the nutritional risks of transit bipartition?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Because part of the food stream is rerouted, there is still some risk of vitamin and mineral deficiencies, so lifelong supplementation and monitoring are recommended. Studies suggest that preserving the duodenum may lower this risk compared with operations that exclude it, but regular follow-up remains important.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Why have metabolic surgery in Mexico?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Patients from Texas and across the U.S. often choose Piedras Negras for high-quality bariatric and metabolic care at a fraction of U.S. costs, with the convenience of being just 15 minutes from Eagle Pass. The most important factors, however, are the surgical team&#8217;s training and the quality of follow-up care \u2014 not price alone.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Medical disclaimer: This content is for informational and educational purposes only and does not replace a medical consultation.
