I've had non-stop liquid diarrhea for three days. what can i do to stop it?

Avoid milk products.: Diarrhea is often due to a virus, but can be caused by certain bacteria, toxins, or medications. Most diarrhea resolves on its own. If it lasts more than three days, or if there is abdominal or rectal pain, blood or a fever above 101F, see your healthcare provider. Avoid high fat foods and milk and ice cream. Pepto-Bismol can be helpful. Soup broth or Gatorade helps replace fluids.
