4. Loose stools
Another very common symptom associated with food poisoning is diarrhea. It happens for the same reason that vomiting does. Your body is trying to expel the infection in the gut, and in order to do so, it will evacuate the bowels. In the beginning stages of food poisoning, your bowels will become noticeably loose, but as it progresses, they will be extremely watery.
You’ll also likely have the urge to use the bathroom repeatedly and could experience pain when you do go. Though it isn’t pleasant, diarrhea is one of the most effective ways the body can rid itself of harmful substances, like the pathogens that cause food poisoning.
