Why This Matters
The timing of depression versus GI diagnoses differs by condition: depression commonly comes before IBS but often follows Crohn’s disease. That matters because it suggests different gut–brain pathways and could change how clinicians screen and follow patients for mental health and GI symptoms.
Who Should Pay Attention
Adults with IBS, Crohn’s disease, or ulcerative colitis; GI and mental health clinicians; researchers studying the gut–brain axis.

What To Know
Researchers analyzed >630,000 participants in the NIH All of Us Research Program and validated results in the University of California Health Data Warehouse (>11 million patients). They examined patients with both depression and a GI diagnosis whose first recorded diagnoses were >6 months apart to study diagnosis order.
Across datasets, depression appeared before IBS in most cases, while Crohn’s disease more often appeared before depression; UC showed intermediate patterns. The study shows patterns in electronic health record diagnoses, not biological causation. A diagnosis recorded earlier does not prove the condition began earlier.
The findings point toward different likely contributions of brain-to-gut versus inflammation-driven gut-to-brain pathways in different diseases and support tailored attention to mental health screening in IBD care.
Keep In Mind
Results are from retrospective electronic health record analyses (All of Us and UC Health Data Warehouse). A recorded diagnosis appearing first does not prove the disorder biologically started first. Healthcare-seeking behavior and coding can influence timing.
