Herein, can you get sick from swallowing a fly?
According to Dr. Pritt, for the most part, eating a bug isn't cause for worry. In general, your body will digest arthropods, which include arachnids like spiders, mites, and ticks, and insects such as gnats, flies, mosquitoes, fleas, and bedbugs, “just like any other food,†she says.
Beside above, can you swallow a fly into your lungs? Unlike your stomach, your lungs won't digest the bug. In your lungs, the bug will get trapped in a layer of slimy mucus. Maybe you're thinking “Gross, there's slime in my lungs!†But it's good to know the mucus is there for a reason. It protects your lungs and airways from situations just like this one.
People also ask, what can happen if you swallow a fly?
Flies for example can carry Shigella, which can cause severe and often bloody diarrhea. “If this happens, it usually resolves itself within a week, but if it's severe, it may require antibiotics,†Dr. Pritt says.
What should I do if I swallow a fly?
Don't worry, you're not going to turn into a fly! If you swallowed it then it's probably ended up in your stomach. It will get digested along with anything else you've eaten (hopefully tasty food rather than more flies!) and then whatever's left will come out the other end when you visit the toilet.
