Food and Symptom Diary: Free Template for IBS, IBD and GI Visits

A food and symptom diary records what you eat and drink, how your gut responds, and other factors such as sleep, stress and medicines. For people with irritable bowel syndrome (IBS), inflammatory bowel disease (IBD) or undiagnosed gut symptoms, it gives a gastroenterologist or registered dietitian something concrete to review. The American Gastroenterological Association (AGA) advises that patients provide dietary information before seeing a registered dietitian to help build an individualized plan. This page describes the template, how long to keep it and how to summarize it.

Your food and symptom diary template

The template on this page can be filled in on screen or printed blank to complete by hand. Each row records one timed event, such as a meal, a bowel movement or a symptom, so the order of events stays clear. The columns are:

Column	What to write
Date and time	The clock time of the entry, to the nearest 15 minutes
Food and drink	What you had and roughly how much
Symptoms	Pain, bloating, gas, nausea or other symptoms, each rated 0 to 10
Bowel movement	Time, Bristol stool type 1 to 7, urgency yes or no, blood yes or no
Sleep	Hours slept the night before and whether sleep was broken
Stress	A 0 to 10 rating for the day
Cycle	Day of your menstrual cycle, if it applies to you
Medicines and supplements	Name, dose and time, including over-the-counter products
Notes	Anything unusual, such as travel, illness, alcohol or a skipped meal

Leave cells empty when nothing happened. A symptom-free day shows your clinician what a good day looks like.

What to record each day, and why

Times come first because symptoms often lag behind food. Monash University's FODMAP team notes that food takes roughly 12 to 48 hours to travel through the gut, so a symptom soon after a meal may have nothing to do with that meal. The team suggests reviewing foods from the 48 hours before symptoms with a dietitian, which requires timed entries.

Stool form is recorded with the Bristol Stool Form Scale, which runs from separate hard lumps at type 1 to entirely liquid stool at type 7. Its original study found stool form tracked gut transit time better than stool frequency did. Clinicians assign the IBS subtype from the predominant stool form on days with abnormal bowel movements, with types 1 and 2 counted as hard and types 6 and 7 as loose. The Bristol stool chart guide for IBS describes each type.

Women with IBS often have more symptoms during their periods, and in one study of IBS journals, the reviewing providers said they wanted information on stress and non-gut symptoms that the journals lacked. Medicine times let a clinician match a stool change to a new laxative or supplement.

Symptoms to report promptly instead of only logging

Some entries should prompt a call instead of waiting for your appointment. A review of IBS diagnosis lists overt bleeding, passing stool at night, unintentional weight loss and a recent change in bowel habits among the alarm features that point toward other conditions. The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) adds black, tarry stools and anemia to that list.

MedlinePlus, from the National Library of Medicine, advises getting medical help right away for blood in the stool or sudden, sharp belly pain, and contacting a provider for fever with pain, unexplained weight loss, or an inability to keep down food or liquids. If you have IBD and your care team has given you a written plan for flares, follow its instructions. Recent diary entries give the team useful detail when you call.

How long to keep it before your appointment

For bowel symptoms, two weeks is a defensible minimum. In the Rome IV approach to IBS, a 14-day bowel diary is suggested to categorize the IBS subtype most accurately. Three to four weeks gives more chances to see whether a suspected link repeats.

A single bad day rarely tells you much. A painful evening after a restaurant meal may reflect something eaten the day before, a short night or the start of a period. A pattern is something that repeats under similar conditions.

Keep eating your usual diet while you record. This matters most for gluten: the NIDDK says doctors do not recommend starting a gluten-free diet before celiac disease testing, because the diet can affect the results.

Reading your own patterns without over-restricting

When eight providers reviewed the same 17 IBS food and symptom journals, their agreement on trigger foods was poor, and the authors recommended structured elimination and rechallenge instead. Treat any pattern you notice as a question for your visit.

When a diet change is warranted, AGA guidance calls for time-limited trials, with the restriction phase of the low FODMAP diet lasting no more than 4 to 6 weeks before foods are reintroduced. FODMAP stands for fermentable oligosaccharides, disaccharides, monosaccharides and polyols, a group of carbohydrates. The same guidance names people with an eating disorder, those at risk of malnutrition and those who are food insecure as poor candidates for restrictive diets.

Over-restriction is a particular risk in IBD. The Crohn's & Colitis Foundation notes that food avoidance is common in IBD, malnutrition rates of 20% to 85% have been cited, and avoiding fiber in Crohn's disease has been associated with a greater risk of flares. In a Mayo Clinic pilot, about 10% of IBD patients screened positive for avoidant/restrictive food intake disorder (ARFID), and their gastroenterologists identified none of them. Fear of eating, weight loss or a shrinking list of safe foods are worth raising with your care team. If you have a history of disordered eating, tell your clinician before starting a detailed food log. The guide to when a food diary becomes too restrictive covers warning signs in more depth.

Turning weeks of entries into a one-page summary

A short visit leaves little time to read weeks of rows, so condense the diary into one page and bring the full record as backup. Report raw counts and leave conclusions to your clinician. An illustrative layout:

Section	Example entry
Period covered	14 days, with dates
Bowel pattern	1 to 4 movements a day; 5 days with type 6 or 7; no days with type 1 or 2
Urgency, blood, night	Urgency on 6 days; no blood; woke to pass stool twice
Symptoms	Bloating on 9 days, most often rated 4 to 6
Possible links	Bloating the evening after a large lunch on 5 of 7 occasions
Questions	Does this fit an IBS subtype? Would a dietitian referral help?

Counting how often a suspected link did and did not repeat keeps the summary honest. List current medicines and recent changes at the top. If you are seeing a dietitian, the guide to preparing for an IBD dietitian appointment with a seven-day food record covers that visit.

Paper diary or app

Both formats work if entries are made at the time. A paper diary needs no account and keeps your data off any server. Its weakness is late entry: in a study of chronic pain patients, paper diaries showed 90% reported compliance but only 11% actual compliance, while electronic diaries reached 94%, because many paper entries were filled in after the fact.

Apps can timestamp entries and total counts automatically. Before choosing one, check where entries are stored and whether you can print a summary. People with an established IBD diagnosis may prefer a condition-specific record, such as the 14-day Crohn's symptom diary or the ulcerative colitis symptom diary.

Whatever the format, a useful diary has timed entries, consistent ratings and at least two weeks of ordinary eating, condensed into counts your clinician can read in minutes. Use it to describe what happened, report warning symptoms promptly, and change your diet only through a structured, time-limited plan with your gastroenterologist or dietitian.
