An IBS diary for a VA claim works best as a weekly tally: on how many days did you have abdominal pain related to a bowel movement, and which bowel changes came with it? Since May 19, 2024, VA's irritable bowel syndrome (IBS) criteria count exactly those things over the previous three months. A weekly count kept at the time matches how the rule is written, without asking you to score yourself.

What the IBS rating counts

VA rates IBS under Diagnostic Code 7319. Every level requires abdominal pain related to defecation during the previous three months, plus two or more of six listed changes.

RatingAbdominal pain related to defecation during the previous three monthsPlus two or more of these
30%At least one day per weekChange in stool frequency; change in stool form; altered passage (straining or urgency); mucus in the stool (mucorrhea); bloating; a feeling of distension
20%At least three days per monthSame list
10%At least onceSame list

VA's announcement of the change says no current rating changes solely because of the update, and claims pending on May 19, 2024 were considered under both the old and new criteria, with the more favorable applied. The IBS condition guide covers service connection and the older criteria.

Weekly IBS diary: print one page per three months

For each week, count the days with abdominal pain related to a bowel movement, then mark which listed changes you actually had. Count a day only once, however many episodes it held.

Behind the weekly page, keep short daily notes on the days symptoms happened: when the pain began, whether it came before, during or after a bowel movement, what changed, what you took, and what the episode interrupted. Record symptom-free weeks as zero. An accurate zero is useful information.

Fictional example: "September 5, 8 a.m. Cramping began before two urgent bowel movements and eased afterward. Looser stools than usual; bloating until lunch. Delayed a 9 a.m. bus trip and used the medication my clinician recommended. Written that evening." The sample is not a diagnostic finding.

You may use a personal scale for pain, but do not let a number replace the description. Keep a possible food trigger separate from a cause a clinician has confirmed. If you have another digestive diagnosis, record what your clinician said instead of labeling every episode IBS.

Summarize three months without smoothing away the variation

At the end of 13 weeks, write two or three sentences from the tally. A fictional example: "Pain related to bowel movements on at least one day in 10 of the last 13 weeks, and on three or more days in eight of those weeks; urgency and looser stools on most pain days." Keep the weekly pages and daily notes behind the summary, and include the weeks when symptoms improved. Do not turn an approximate memory into an exact count.

The intestinal conditions DBQ is completed by a clinician. Bring the diary and your treatment history to your clinician, especially if symptoms are new, worse or different; a clinician can confirm whether IBS is the right diagnosis and whether something else needs attention. VA accepts medical and lay evidence. If VA has already denied an increase, compare that decision with the criteria it applied.

A real denial separated diarrhea from abdominal pain

In Board decision A25094792, October 31, 2025, the record documented daily diarrhea, but the VA exam did not identify abdominal distress and the veteran had not described the abdominal pain the criteria require. The Board of Veterans' Appeals (the Board) considered both the older and the amended criteria and denied an initial compensable IBS rating.

The decision did not say the diarrhea was unimportant. It shows why one symptom cannot stand in for another: an entry about frequent bowel movements does not tell a reviewer whether pain occurred, whether it was related to the bowel movement, or which other changes came with it. That is why the weekly page has separate columns. Record pain only when it happened, and never add it because the criteria mention it. If an exam or treatment note describes your symptoms inaccurately, point to the specific discrepancy and raise it with the clinician.

This was an appeal of an initial rating. The recording lesson carries over to an increase request, but your claim period and the criteria that apply to it still need their own review.

How IBS appeals turn out at the Board

In Claim Raven's analysis of 2024 to 2025 Board decisions, IBS was a decided issue in 968 condition records: 45.0% favorable, 47.2% denied and only 7.7% remanded. Among 363 denied IBS records with a classified reason, 51.2% were denied because the severity criteria were not met and 29.5% for no current diagnosis. IBS records whose evidence included a symptom log were favorable 59.8% of the time (132 records), compared with 42.7% of records without one. These are appeals of already-disputed claims, so the figures describe patterns, not your odds, and they do not show that a log caused a grant. The lay-evidence study explains how Claim Raven measures the Board's use of personal accounts.
