First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether giving oral probiotics to adolescents before non-cardiac, non-digestive surgeries could reduce anxiety and depression afterward. 150 teens aged 12-17 were randomly assigned to receive either probiotics or a placebo. Researchers measured anxiety and depression scores over two months after surgery, along with blood markers of inflammation. The goal is to find a simple way to improve mental recovery after surgery.
