How to keep a food and symptom journal your GI will actually use

There are two jobs a journal can do. One is helping you spot your own patterns, which we cover in how to keep a Crohn's food diary that actually finds your triggers. The other is giving a gastroenterologist, IBD nurse or dietitian something they can read in a couple of minutes and act on. The second job has different rules, and most journals are not written with it in mind.

This guide is about that second reader. It is not an appointment checklist (that lives in how to prepare for a gastroenterologist appointment). It is about how to record things day to day so that, when the appointment comes, the record is already usable.

What the person across the desk is trying to work out

In a short appointment, your care team is usually trying to answer a handful of questions. Is the disease active, quiet, or changing? Is the current treatment doing what it was meant to? Are the symptoms more likely to be inflammation, or something else, such as IBS-type symptoms, an infection, a medication effect or a food intolerance? Is anything happening that needs a test sooner rather than later?

Each of those questions is answered by numbers and dates far better than by adjectives. "It's been rough" gives them almost nothing. "Five to seven stools a day for the past ten days, two of them at night, blood on four days, up from two a day last month" gives them a lot. The aim of a journal written for a clinician is to make the second sentence easy to produce.

The fields worth recording, and how

Consistency matters more than detail. A field recorded the same way every day for a month beats a richly described field recorded on the bad days only. This table sets out a small set of definitions that hold up over time.

Pick your scales on day one and do not change them. If "moderate" urgency means "I changed my plans" in week one, it needs to mean the same thing in week five, or the trend is meaningless. Three-level scales (mild, moderate, severe) are what people actually keep filling in. Ten-point scales tend to drift.

Counts, not adjectives

The single most useful habit is writing a number wherever a number exists. A number can be compared with last month; "bad" cannot be compared with "pretty bad".

• Instead of "lots of trips to the bathroom", write "6 today, 2 overnight".
• Instead of "loose", write "Bristol 6".
• Instead of "some blood", write "blood yes, streaks on paper".
• Instead of "forgot my meds a bit", write "missed evening dose Tue and Thu".
• Instead of "lost weight", write "down from 68.2 to 66.9 kg over three weeks".

What to leave out

Clinicians rarely want everything. Long free-text paragraphs, meal photos and pages of speculation about causes all slow the reader down. Keep a notes field for the one line that matters each day, and keep your theories for the conversation, where you can ask about them directly.

Do keep the boring days. A run of entries that say "2 stools, Bristol 4, no blood, felt fine" is evidence of remission, and it is just as useful to your team as a record of a flare. Without it, a journal looks like a list of complaints, and the good stretches vanish.

Paper or app?

Both work if you keep them consistent. Paper is simple, private and needs no setup; its weakness is that you have to do the counting and summarising yourself before the appointment, and it is easy to fill in from memory at the end of the day. An app stamps the time automatically, keeps the scales fixed and can do the arithmetic, which removes most of the work of producing a summary.

If you prefer paper, our free 7-day food and symptom log uses the fields in the table above, and the Bristol stool log covers stool form, frequency, blood and urgency on a single sheet.

Turning 30 days into one page

Most clinicians will read one page. Few will read thirty days of raw entries in a short appointment. Whether you use paper or an app, the summary you bring should look something like this:

1. Date range and days logged. "1 to 30 September, 27 of 30 days logged." A sparse record should read as sparse.
2. Stool frequency. Average per day, highest day, and how many nights you woke to go.
3. Stool form. The most common Bristol types, and whether they shifted during the month.
4. Blood and urgency. Number of days with blood; number of days with moderate or severe urgency.
5. Pain and other symptoms. The two or three most frequent, with typical severity and time of day.
6. Food patterns. Foods you tolerated consistently, and foods that most often came before symptoms, with counts such as "4 of 6 times".
7. Medications. What you took, any changes, and any missed doses.
8. Weight. Start and end of the period.
9. Context. One or two lines: an infection, travel, a hard month at work.
10. Your top three questions. Written at the bottom, in order.

Counts like "4 of 6 times" are deliberately modest. They describe what happened in your record; they are not proof that a food causes anything. Your team can help decide whether a pattern is worth testing, and whether a dietitian should be involved before you cut anything out.

A word on privacy

A symptom journal is sensitive health information. Share the summary with the people who need it, rather than the whole record. If you use an app, check where your entries are stored, whether you can export and delete them, and whether anything is shared with third parties. If you share a PDF by email or a patient portal, it is worth knowing who else has access to that inbox or account.

Symptoms that need same-day care

A journal is for patterns over weeks, not for deciding whether something is an emergency. Contact your IBD team, an urgent care service or the emergency department the same day if you have severe or worsening abdominal pain, heavy rectal bleeding, a high fever, signs of dehydration, vomiting with a swollen abdomen and no passing of stool or gas, or you cannot keep fluids down. The NHS page on Crohn's disease and NIDDK's guidance on eating with Crohn's are good plain-language background, but they do not replace a call to your team.

What to ask your team

• Which of these fields are most useful to you, and is there anything you would like me to record that I am not?
• Do you prefer a summary on paper, a PDF before the visit, or something through the patient portal?
• Is there a symptom score your clinic uses that I should record in the same way?
• How often should I weigh myself, and what change would you want to hear about between visits?
• Are any of these food patterns worth testing with a dietitian, rather than me changing my diet on my own?
• Which changes in my journal should make me contact you before the next appointment?
