Our Summary

This research paper reviews additional studies on the impact of weight-loss surgery (bariatric surgery) on brain function, following an initial review in 2016. It includes 13 new studies, on top of the previous 18, bringing the total to 31. The majority of the studies highlighted some improvements in brain function after the surgery. However, these improvements were not seen in all areas of brain function and varied from person to person. The research also looked at how different types of weight-loss surgery and changes in mental health or quality of life after surgery might affect brain function. The findings suggest that weight-loss surgery could have a positive effect on brain function in people with obesity, but more comprehensive studies are needed to confirm this.

Doctor’s Tip

A doctor may tell a patient considering obesity surgery to be aware of the potential impact on brain function. It is important to discuss any concerns or questions with your healthcare provider, as they can provide personalized advice and guidance throughout the process. Additionally, following a healthy lifestyle, including regular exercise and a balanced diet, after surgery can help maintain and enhance the positive effects on brain function.

Suitable For

Patients who are typically recommended obesity surgery are 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. These patients may have tried other weight loss methods such as diet and exercise but have not been successful in achieving long-term weight loss. It is important for patients to have a thorough evaluation by a healthcare provider to determine if they are a good candidate for obesity surgery and to discuss the potential risks and benefits of the procedure.
