Free tracker
Need one week of readable gut data?
Start with one readable week. The printable tracker and CSV keep the log small on purpose: date, stool type, timing, symptoms, meals, caffeine, sleep, stress, meds, and one note. Fill one row per day, then compare that week against one experiment instead of relying on memory.

Track daily
Date, stool time, Bristol type, and color.
Keep symptoms simple
Urgency, pain, and bloating use small 0-3 scales.
Add context
Meals, caffeine timing, sleep, stress, and meds stay in one row.
Review weekly
Compare one baseline week against one clean experiment week.

Use the printable if you want a one-page baseline. Use the CSV if you prefer Sheets, Numbers, or Excel.
How to use the tracker
- Run a baseline first. Seven ordinary days are more useful than one "perfect" day.
- Keep the notes short. One line per day is enough if it is consistent.
- When you test something, change one lever only: coffee timing, lactose, polyols, or fiber.
- Compare weeks, not isolated days. Monday versus Tuesday usually tells you very little.
Watch-outs
- Do not stack three changes at once and expect a clean signal.
- If you see blood, black stool, fever, severe pain, or faintness, stop self-testing and seek care.
- This tracker is for patterns and questions. It is not a diagnostic tool.
