Can a colonoscopy cause a hernia? how do i treat it?

Hernias development : Colonoscopy injects a lot of air into the colon and increases intravenous-abdominal pressure. If you have a hernia, the increased pressure will cause a pre-existent hernia to protrude. You should see a surgeon to have it repaired. The hernia has probably been there for awhile and protruded after to increase in abdominal pressure.
