RNY Gastric Bypass Surgery
Info
RNY Gastric Bypass surgery is a common type of bariatric surgery worldwide, performed after sleeve gastrectomy surgery. While it was previously the first choice for morbid obesity treatment, it has now become an alternative surgery for selected patients.
RNY Gastric Bypass works by both shrinking the stomach and reducing nutrient absorption by directly passing nutrients from the smaller stomach to the small intestine.
Who is a suitable candidate for RNY Gastric Bypass?
RNY Gastric Bypass is now applied to patients who are not suitable for sleeve gastrectomy, such as those with severe reflux or in need of a revision of a previous sleeve gastrectomy. It is also recommended for patients with a sweet tooth, severe gastroesophageal reflux, or where diabetes control is a priority.
Additional advantages and disadvantages of RNY gastric bypass include:
Advantages
Effective for long-term weight loss: RNY gastric bypass is one of the most effective weight loss surgeries available, and patients typically lose a significant amount of weight in the first year after surgery. Research has shown that patients can maintain this weight loss for up to 10 years or more.
Improved health outcomes: RNY gastric bypass can lead to significant improvements in health outcomes for patients with obesity-related conditions such as type 2 diabetes, high blood pressure, and sleep apea.
Reduced risk of cancer: Studies have shown that RNY gastric bypass can reduce the risk of certain types of cancer, such as breast and colon cancer, in patients with obesity.
Improved quality of life: Many patients report an improved quality of life after RNY gastric bypass, with increased energy levels, improved mobility, and greater self-confidence.
Disadvantages
Risk of complications: Like all surgeries, RNY gastric bypass carries some risk of complications, including bleeding, infection, and blood clots.
Long-term dietary restrictions: Patients who undergo RNY gastric bypass must follow a strict diet that limits their intake of certain foods and nutrients for the rest of their lives.
Nutritional deficiencies: Because RNY gastric bypass alters the digestive system, patients are at risk of developing nutritional deficiencies, particularly of iron, vitamin B12, and calcium.
Dumping syndrome: Dumping syndrome is a condition that can occur after RNY gastric bypass, where food moves too quickly through the stomach and into the small intestine, leading to symptoms such as nausea, vomiting, and diarrhea.

Process
The surgery is performed laparoscopically, similar to sleeve gastrectomy surgery. First, a small stomach pocket of approximately 50-70 cc is created from the initial part of the stomach, the cardia region, and separated from the main stomach using staples.
Next, anastomosis is performed by joining the pocket 60-100 cm ahead of the small intestine. Finally, the end of the small intestine, which brings remaining secretions from the stomach and duodenum, is joined to the main intestinal system. The remaining stomach, excluding the pouch-pocket, is not removed.
The average operation time is 1.5 hours.
After Surgery
After RNY gastric bypass surgery, the procedure typically lasts 1.5 hours and is performed using laparoscopic closed technique.
Hospitalization is required for 3-4 days and oral food intake can begin after 2 days. It typically takes 1 week to return to normal life.
Regular follow-up during the first year after surgery is crucial, and it is important for patients to maintain sufficient vitamin and mineral intake during this time. Adequate follow-up and nutritional intake are key factors in achieving success after RNY gastric bypass surgery.
Nutrition after RNY Gastric ByPass
After RNY gastric bypass surgery, there are three phases of post-operative nutrition. The first phase lasts for eight days and involves a liquid diet consisting of unsweetened fruit juices, protein-rich liquid drinks, lactose-free milk, unsweetened vegetable milk, and grain-free soups enriched with meat and chicken juices. The second phase, which lasts from Day 9 to Day 22, is the puree period and expands the patient’s diet to include eggs, cheese, low-sugar fruit, vegetable purees with yogurt or minced meat, and protein-enriched dairy products.
The third phase begins on Day 23 and involves the adoption of a standard and healthy nutrition model specially designed by a dietitian. This diet includes all food groups specific to a healthy diet and is based on the patient’s avoidance of fast food, acidic drinks, alcohol, and sugary foods. This stage is important in terms of developing healthy eating habits and making them a lifestyle.
Lifelong follow-up with a dietitian is critical to ensure that patients with RNY gastric bypass do not have protein, vitamin, and mineral deficits. It is recommended that patients visit a dietitian every three weeks for check-ups to maintain a healthy diet and prevent obesity.
