- If your stool looks bloody, oily, fatty, or watery
- Other symptoms you have and how long you’ve had them
- If you have a family history of chronic diarrhea
- Places you've traveled to recently
- Unusual foods you've tried in the last little while
- Any medication or supplements you're taking
- If you've lost a lot of weight
