When should I call my doctor about diarrhea?

If you have diarrhea that fails to improve or resolve completely, you should call your healthcare provider. Keep track of any other symptoms you may be experiencing – this includes fever, vomiting, rash, weakness, numbness, lightheadedness, dizziness, weight loss and blood in your stool. If you have any concerns, it’s always best to call your healthcare provider.
