Diagnosis

Since diarrhea has many possible causes, your doctor will ask you about your personal circumstances. Recent travel history or exposure to family members with similar symptoms might suggest an infection.

Your doctor will review your symptoms and examine you. If you have severe symptoms, your doctor also may ask for a stool sample. The specimen will be analyzed in a laboratory to look for infectious causes.
