If you were to envision the kind of accident that would cause a person’s bowels to explode out of their body, you might imagine some sort of gruesome stabbing or grisly car accident. You’d probably never imagine that something as commonplace and harmless as a sneeze would cause this kind of ghastly injury—but that’s exactly what happened to a Florida man earlier this month.
The man had recently had abdominal surgery and was suffering from wound dehiscence—where his surgical scar wasn’t healing properly. While eating breakfast, the man first sneezed, then began coughing. He noticed pain and a wet sensation on his lower abdomen—only to discover several loops of his bowel had burst through his unhealed wound.
The man was rushed to hospital for emergency surgery where his bowels were returned to his abdomen.
Sneezing is normally a protective mechanism that keeps potentially harmful things—such as dust, bacteria and viruses – out of our respiratory system. The process is controlled by the so-called “sneezing center” in the brain’s medulla (which governs autonomic functions, including breathing). It’s activated by the presence of irritants in the lining of the nose and airways, which send impulses to the center.
The response is a closing of your eyes, throat and mouth while your chest muscles contract—compressing your lungs and driving air out of your respiratory system. This forces whatever triggered the response “out” of your system at an impressive speed—up to 15.9m/s (35mph) in some cases.
But despite the benefits of a good sneeze, it can sometimes come with a greater risk of injury than many might realize.
For instance, violent sneezing can cause the lung to herniate through the intercostal muscles between the ribs—usually at a point of weakness. This is typically a result of morbid obesity, chronic obstructive pulmonary disease, diabetes or smoking.
