Adherence
Metabolic and bariatric surgery (MBS) slightly increases the risk of substance use disorders and suicide deaths more than 2 years post-surgery compared to nonsurgical controls.
Be aware that while MBS improves mental health symptoms, it may slightly increase the risk of substance use disorders and suicide more than 2 years after surgery. Long-term mental health support and monitoring are essential to mitigate these risks.
LimitedRefutesVERY_LOW confidence
MBS may slightly increase suicide deaths (1/1000 more people, 95% CI 0 fewer to 3 more; very low certainty) and substance use disorders (4/100 more, 95% CI from 1 to 9 more; low certainty) > 2- years post- surgery.
Why this rating
Evidence certainty is rated 'low' for substance use and 'very low' for suicide.
