And what about the lungs? A number of things could explain the problems in his lungs—including infections from soil bacteria he might encounter in his construction work or a parasitic infection found in Central America. But the cause that best fit was common pneumonia and, more specifically, based on the distribution of opacities in his lung, pneumonia caused by aspiration (inhaling food particles or other things that are not air)—which is something that can happen when people drink excessive amounts of alcohol, as the man regularly did.
“Ethanol impairs consciousness and blunts protective reflexes (e.g., cough and gag), which disrupts the normal control mechanisms of the upper aerodigestive tract,” Dhaliwal noted.
And this is where Dhaliwal made a critical connection. If the man’s drinking led him to develop aspiration pneumonia—accidentally getting food in his lungs—he may have also accidentally gotten nonfood in this gastrointestinal tract at the same time.
Critical connection
The things people most commonly swallow by accident include coins, button batteries, jewelry, and small bones. But these things tend to show up in imaging, and none of the imaging revealed a swallowed object. Things that don’t show up on images, though, are things made of plants.
