IBS & irritable bowel decisions — 2026

The appellant is granted SMC(o) and SMC(r)(1) based on his service-connected disabilities, including PTSD, glaucoma, foot drop conditions, sleep apnea, migraines, overactive bladder, and various musculoskeletal issues. He does not qualify for higher rates due to the anatomical loss or use of extremities.

The Board has decided to remand the case due to inadequate examination and incomplete analysis of service connection for Irritable Bowel Syndrome (IBS) and objective indications of a disability manifested by diarrhea. The examiner is requested to provide an opinion on whether IBS or any diagnosed gastrointestinal disability is related to the Veteran's in-service Gulf War exposure.

The Board has decided to remand the case due to a lack of development regarding whether the gastrointestinal symptoms, including chronic constipation and IBS, are caused or aggravated by service-connected disabilities. The AOJ should obtain an addendum opinion from an appropriate clinician to address causation and aggravation.
