Evidence strength
Mark what you already have below and your evidence strength appears here.
Specialist opinion
Highest value0 of 3 collectedGastroenterologist evaluation confirming IBS (diarrhea-predominant, constipation-predominant, or mixed subtype) with documentation of stool frequency, consistency (Bristol Scale), and abdominal pain pattern meeting Rome IV criteria.
Not marked
A medical opinion connecting IBS to service-related factors including combat stress, PTSD (gut-brain axis), traumatic abdominal injury, antibiotic use during deployment, or infectious gastroenteritis acquired during service.
Not marked
Colonoscopy or sigmoidoscopy report confirming absence of inflammatory bowel disease, malignancy, or other structural pathology — required to support the IBS diagnosis.
Not marked
Treatment records
0 of 2 collectedRecords showing medications prescribed (dicyclomine, hyoscyamine, rifaximin, linaclotide) and dietary recommendations (low-FODMAP diet), documenting treatment need and severity.
Not marked
Serial weight measurements and nutritional records showing weight loss or dietary restriction caused by IBS. This is supporting context for severity — it is not itself a DC 7319 criterion (the rating is based on how often you have defecation-related abdominal pain plus associated symptoms; 30% is the maximum).
Not marked
Lay statements
0 of 3 collectedA personal log — ideally covering three months — recording each day you have abdominal pain related to a bowel movement, plus associated symptoms (change in stool frequency or form, straining or urgency, mucus, bloating, distension). Under DC 7319 the number of pain days (once in 3 months, at least 3 days a month, or at least weekly) plus two or more associated symptoms is the primary rating driver.
Not marked
A written statement from someone who can describe observable symptoms and how your condition affects daily life.
Not marked
