, can cause yellow
diarrhea, fever, and flu-like symptoms.
Yellow stool is unusual, and may be a symptom of a serious medical condition. Seek immediate medical care (call 911) for severe abdominal pain, stool with blood or pus, high fever (higher than 101 degrees Fahrenheit), significant vomiting, seizures, changes in mental status, or sudden behavior changes.
