Our Summary
This research paper looks at two types of surgical procedures used to help people who have regained weight after undergoing previous weight loss surgeries. The two procedures compared are the Roux-en-Y gastric bypass (RYGB), which is the standard practice in the U.S., and the one anastomosis gastric bypass (OAGB), which is popular internationally. The research compared the safety and effectiveness of these procedures on patients who had gained weight after undergoing either a sleeve gastrectomy (SG) or gastric banding (LAGB).
The research found that both procedures had similar results: they took about the same amount of time, the patients lost about the same amount of weight in the first month after surgery, and there was no significant difference in the rates of complications or re-operations.
The researchers concluded that the OAGB procedure could be a safe alternative to the RYGB for people who need a second weight loss surgery. However, they noted that more research is needed to confirm these findings.

Doctor’s Tip
One helpful tip a doctor might give to a patient undergoing gastric bypass surgery is to follow a strict post-operative diet plan. This typically includes consuming small, frequent meals that are high in protein and low in carbohydrates and fats. It is important to avoid sugary and processed foods, as well as carbonated beverages, which can cause discomfort and potentially lead to complications. Following the recommended diet plan can help patients achieve optimal weight loss results and maintain their overall health after surgery.
Suitable For
Patients who are typically recommended for gastric bypass surgery include those who have a body mass index (BMI) of 40 or higher, or a BMI of 35 or higher with obesity-related health conditions such as type 2 diabetes, high blood pressure, or sleep apnea. Additionally, patients who have tried and failed to lose weight through diet and exercise or other non-surgical methods may be considered for gastric bypass surgery.
It is important for patients to undergo a comprehensive evaluation by a multidisciplinary team of healthcare providers including a bariatric surgeon, dietitian, psychologist, and other specialists to determine if gastric bypass surgery is the right option for them. Patients should also be committed to making lifestyle changes, including adopting a healthy diet and regular exercise routine, to achieve successful weight loss and maintain long-term results.
Overall, gastric bypass surgery is a valuable tool for patients who are struggling with severe obesity and related health conditions, and can help them achieve significant weight loss and improve their overall quality of life.
Timeline
Before undergoing gastric bypass, a patient typically goes through a series of evaluations and consultations with a healthcare team, including a surgeon, nutritionist, psychologist, and possibly an exercise physiologist. They may also need to make lifestyle changes, such as quitting smoking or losing a certain amount of weight before surgery.
After gastric bypass surgery, the patient will spend a few days in the hospital recovering before being discharged. They will need to follow a strict diet plan, starting with clear liquids and gradually progressing to solid foods over time. They will also need to take vitamin and mineral supplements to prevent deficiencies.
In the months following surgery, the patient will attend follow-up appointments to monitor their progress and make any necessary adjustments to their diet or exercise regimen. They will continue to lose weight steadily, with the most significant weight loss occurring in the first year after surgery.
Over time, the patient will need to make permanent lifestyle changes to maintain their weight loss and prevent regaining weight. This may include regular exercise, healthy eating habits, and ongoing support from their healthcare team.

- What dietary changes will I need to make after the surgery?
- How much weight can I expect to lose and how quickly can I expect to see results?
- Will I need to take any supplements or vitamins after the surgery?
