My claim for ervice connection for Irritable Bowel Syndrome (IBS) as a presumptive service connected disability due to my service in the Gulf War per 38 C.F.R §3.317 was denied. Wondering how I can succesfully appeal. VA DENIAL LETTER “ Service connection is not permitted if there is affirmative evidence that the disability was unrelated to military service in the Gulf War. Service connection for unexplained chronic multi symptom illness to include irritable bowel syndrome is denied because evidence established that this disability result from poor diet and fitness. Your service treatment records do not contain complaints, treatment, or diagnosis for this condition. We did not find a link between your medical condition and military service. On examination, the examiner indicated that your stated symptoms do not meet the criteria for a diagnosis for irritable bowel syndrome and are most likely the result of poor dietary and fitness habits.” SERVICE INFORMATION & MEDICAL DIAGNOSIS: I served in Southwest Asia during Operation Iraq Freedom.
