Podcast # 450: Probiotics in Gastroenteritis - The Emergency Medical Minute

Author: Sam Killian, MD

Educational Pearls:

  • Viral gastroenteritis alters the gut microbiome and it is theorized that probiotics may help reduce the duration and severity of the disease.
  • Double-blind randomized controlled trial involving almost 900 children with viral gastroenteritis compared 5 days of probiotics to a control group.
  • There was no difference in the rates of severe gastroenteritis between the two groups
  • Probiotics are likely unhelpful for kid with viral gastroenteritis
