Yes, food poisoning can cause diarrhea as the only symptom, especially in cases of viral or bacterial diarrhea illnesses.
Food poisoning can sometimes lead to diarrhea without other symptoms. For example, e.coli food poisoning, a bacterial cause of diarrhea can present with just diarrhea. Other viral causes of diarrhea, like norovirus, can also present with just diarrhea.
Another type of food poisoning, caused by Salmonella, is known to cause diarrhea among other symptoms.
In summary, while diarrhea is a common symptom of various types of food poisoning, it can sometimes occur on its own, depending on the specific cause and individual response.
