The diarrhea causes your body to lose fluids and electrolytes. This makes you feel sick and tired. The watery diarrhea lasts for about a day. Then the diarrhea changes to bright red bloody stools. The infection makes sores in your intestines so the stools become bloody.
Bloody diarrhea lasts for two to five days.
You might have 10 or more bowel movements a day. Fever is usually mild, and most people don't have a fever. You may also have nausea or vomiting. It's easy to get dehydrated when you have diarrhea. The most common complication is called hemolytic uremic syndrome.
