Could be Akagi has diarrhea from eating too much steamboat food, but still since nobody dares translate the text in this manga page and the four pages before this so no one even knows what happened to her until the pages are properly translated.
Judging from the previous strip, Akagi ate an undercooked piece of meat, so it's food poisoning.
