Our Summary

This research paper reviews the effectiveness of a specific type of weight loss surgery called one-anastomosis gastric bypass (OAGB) in treating severe obesity and type-2 diabetes. This surgery is seen as a simpler, safer alternative to the current gold-standard treatment, the Roux-en-Y gastric bypass. The paper found that OAGB has been successful in both the short and long term, helping to improve or even completely resolve type-2 diabetes in patients, regardless of whether they’re obese or not. Two years after the surgery, the rate of diabetes remission and improvement ranged from 67 to 100%, and after five years, the rate was between 82 to 84.4%. The paper also found this surgery to be better than other weight loss procedures, like sleeve gastrectomy and adjustable gastric banding. However, the authors suggest more high-quality studies are needed to confirm these findings.

Doctor’s Tip

A doctor may tell a patient considering gastric bypass surgery to make sure they are fully informed about the procedure and its potential risks and benefits. They may also advise the patient to follow a strict diet and exercise regimen before and after the surgery to maximize the chances of success and to maintain long-term weight loss. Additionally, the doctor may stress the importance of regular follow-up appointments and monitoring to ensure the patient’s health and well-being after the surgery.

Patients who are typically recommended for gastric bypass surgery, including one-anastomosis gastric bypass, are those who:

  1. Have a body mass index (BMI) of 40 or higher (severe obesity) or a BMI of 35 or higher with obesity-related health conditions such as type-2 diabetes, high blood pressure, sleep apnea, or heart disease.
  2. Have tried and failed to lose weight through diet and exercise alone.

It is important for patients considering gastric bypass surgery to consult with a healthcare provider or a bariatric surgeon to determine if they are a good candidate for the procedure. Each patient’s case is unique, and the decision to undergo gastric bypass surgery should be made after a thorough evaluation of their individual medical history and risk factors.
