Bowel Obstruction Symptoms

Name: Bowel Obstruction Symptoms
Creator: Assoc. Prof. Cengiz Dibekoğlu, MD

Colicky pain, vomiting, distension, and failure to pass gas — timelines help, but red flags override.

Early small-bowel obstruction pain comes in waves with bilious vomiting; distal colon obstruction may show marked distension and later feculent vomiting. Complete inability to pass stool or gas is worrying. Continuous pain with tenderness suggests ischemia. Do not ‘wait it out at home’ when vomiting and distension escalate — dehydration and aspiration risk rise quickly. Hernia orifices and peritonitis signs decide whether observation is even appropriate.
