diarrhea for hours
Acute diarrhea is defined as three or more loose or watery stools per day. Diarrhea can be caused by infections or other factors. Sometimes, the cause of diarrhea is not known. Diarrhea caused by an infection usually begins 12 hours to four days after exposure and resolves within three to seven days. A person may have mild to severe diarrhea. Some people with diarrhea also have fever (temperature greater than 100.4ÂºF or 38ÂºC), abdominal pain, or cramping.
