Swallowing fish bones poses significant health risks to the digestive tract
the verdict
SUPPORTED
the evidence backs this
confidence 93/100
While many ingested fish bones pass through the digestive system without incident, clinical literature demonstrates that they pose significant health risks—such as lacerations, impaction, abscess formation, and perforation—that frequently require urgent medical or surgical intervention.
