(SADI Bypass Surgery) Single Anastomosis Duodenal-Ileal Bypass
It is a type of weight loss surgery that offers promising results for individuals struggling with obesity. It reduces the size of the stomach, leading to a decreased food intake as it can hold less food around 100-150 ml. Additionally, by creating a connection between the duodenum and the ileum, the surgery bypasses a significant portion of the small intestine, reducing the absorption of calories and nutrients from the food. This alteration also influences the release of hormones that control hunger, satiety, and metabolism, helping to control appetite and promote weight loss.

The importance of Bypassing the Duodenum
The duodenum is the first part of the small intestine, located just below the stomach. When food leaves the stomach, it enters the duodenum, where several important digestive processes take place.
However, in obese individuals, the duodenum can experience various dysfunctions that contribute to obesity and related health problems. The duodenum plays a role in releasing hormones that regulate hunger and satiety. In obesity, hormonal imbalances can occur, leading to reduced sensitivity to satiety hormones and increased production of hunger-inducing hormones like ghrelin. This can result in overeating and difficulty feeling full, leading to excess calorie intake and weight gain. Insulin resistance can negatively affect the duodenum’s ability to regulate blood sugar levels and may contribute to metabolic disturbances and lead to higher insulin levels. Elevated insulin levels can promote fat storage and hinder fat breakdown, leading to weight gain.
The SADI bypass surgery offers several benefits by partially removing the duodenum. During the procedure, a portion of the duodenum is bypassed, reducing the absorption of calories and nutrients from food. Additionally, hormonal changes occur, helping control appetite and further promoting weight reduction. The surgery has shown positive effects on insulin sensitivity, which benefits blood sugar control, particularly for patients with type 2 diabetes. By preserving some functions of the duodenum while achieving weight loss, the SADI bypass presents a comprehensive approach to managing obesity and related health conditions.
Weight loss with SADI Bypass Surgery
You can lose up to 45% of your total body weight through this procedure. By making lifestyle changes, you can increase it by 5%, and using medicines can add another 10%. In total, you can achieve a 60% reduction in your total body weight with this procedure.
It is highly beneficial for individuals with strong hunger feelings and those who experience frequent and persistent hunger. This procedure is often used for very obese individuals because it offers one of the most aggressive weight loss results provided by bariatric surgery. For example, if a person with a BMI of 50 undergoes the SADI bypass, they can lose up to 20 BMI points and achieve a BMI of 30 or even lower, moving them out of the danger zone of obesity and towards a healthier weight range.
Single Anastomosis Duodenal-Ileal Bypass SADI Bypass Surgery Procedure
During the SADI bypass surgery, the surgeon makes minor cuts in the abdomen. The first step involves creating a sleeve gastrectomy, where a portion of the stomach is removed to make it smaller. Next, the initial segment of the first part of the small intestine (duodenum) is separated from the rest of the duodenum. Then the last 300-350 cm of the small intestine is measured, and the surgeon creates a connection between the duodenum and the last part of the small intestine (ileum). This connection helps bypass a significant part of the small intestine, leading to reduced absorption of calories and nutrients, which ultimately promotes weight loss. After completing the procedure, the incisions are closed. It’s essential for patients to follow post-operative care and make necessary lifestyle changes to support their weight loss journey effectively.

Who Is a Candidate for SADI Bypass Surgery?
Severe Obesity
A body mass index higher than 35 or 40 represents severe obesity. Individuals suffering from severe obesity and related medical issues should consider surgery as a priority.
No severe nutritional deficiencies
Pre-existing nutritional flaws can be a source of the development of medical issues. SADI bypass works to lower nutrient absorption. Thus, patients who are thinking of this operation must not have any underlying severe deficiencies.
Unsuccessful bariatric surgery
SADI gastric bypass surgery polishes the results of bariatric surgery such as sleeve gastrectomy. Thus, individuals dissatisfied with previous surgical results are eligible.
Fertility issues
Women suffering from fertility issues come in the list of
candidates. However, general considerations such as good health status are still valid.
What Should You Expect After a SADI Bypass?
SADI surgery is a big shift and brings numerous changes to your body. Keeping in mind the science of operation, you can experience the following things.
Normally, patients need a hospital stay of 2 to 3 days.
It is crucial to monitor the patient’s health status and to manage mild to moderate discomfort and pain.
Fatigue and diarrhea may also occur in the starting days because the body needs time to adjust to changes.

Overall, a better quality of life due to the prevention of obesity-related diseases.

Recovery Time After SADI Bypass Surgery
The recovery stage is a crucial phase during the weight loss journey. We do not let you feel alone and blank at this critical point. With all the guidance of our surgeon and care, the average recovery period after SADI bypass surgery consists of 6 to 8 weeks. A patient can come back to work in 2 to 4 weeks, depending on the nature of the job or profession. To let the body adjust, moderate activities, exhaustion, and dietary changes are essential in the first few days after operation.
A liquid diet for the first two weeks before progressively switching to soft foods works well. Patients should stick to recommended vitamins, maintain a high-protein diet, and keep themselves hydrated. Moreover, refraining from hard lifting for at least a month can boost the speed of recovery. Visiting your surgeon regularly helps track the development and modification of dietary requirements. Lastly, recommended exercises can be your good companion on the journey as they prevent complications.
Follow-up and Lifestyle Changes
A proper diet plan and appropriate post-operative care are pillars that support recovery and results at the same time. An emphasis on high-protein, low-carb meals is essential to minimize muscle loss. Diet shifts must be gradual and sequential, from clear liquids to blended foods, then soft and eventually solid foods. It is quite easy to avoid dumping syndrome and nausea by skipping overeating and having small, frequent meals. Moreover, one should remain focused on hydration. Regular intake of Iron, B12, calcium, fat-soluble vitamins (A, D, E, and K), and minerals help to cope with the nutritional deficiencies.
While talking about follow-up care, adherence to a surgeon’s prescribed medication matters a lot. Moreover, wound care and following guidance about physical activities is crucial. Plus, it is necessary to gain knowledge of critical conditions that call for consultation with the doctor.
