Everyone has an odd day. A big meal, a late night or a stressful week can change what ends up in the toilet. One poop on its own says very little.
What helps your doctor is the pattern: how often, what shape, and what else was going on.
What a single day misses
Say you log a type 6 on Tuesday. Cleveland Clinic says types 5, 6 and 7 suggest diarrhea (Cleveland Clinic). But was Tuesday a one-off, or the fifth time this week? Did it follow a bad night’s sleep? You can’t tell from one entry.
What two weeks can show
- Your usual. How many times a day is normal for you, and what your usual type is.
- The spread. How often you land in types 1 and 2, 3 and 4, or 5 to 7.
- The extras. How many days had urgency, night-time trips, pain, blood or mucus.
- What was going on. Food, sleep, stress and medicines on the days around the bad ones.
These are things a doctor can work with. They are also easier to say out loud when they are written down.
A pattern is not a cause
If loose days often follow a certain food in your log, that is worth mentioning. It doesn’t prove the food caused it. Bring it to your doctor or dietitian and decide together what to do next.
When not to wait
Some things shouldn’t wait for two weeks of notes. If you are bleeding from your bottom, have bloody diarrhoea or have lost a lot of weight for no reason, the NHS says to ask for an urgent GP appointment or get help from NHS 111 (NHS).
Start small
Log the type and the time. That is enough to start. The printable diary or the Gutsby app (join the waitlist) can do the rest.
