What needs to be proven for a VA claim regarding aggravation of a condition?

To establish a claim for aggravation of a condition with the Department of Veterans Affairs (VA), it is essential to prove that the condition worsened during active service. Aggravation, in this context, refers to an increase in severity of a pre-existing condition that is not merely a temporary exacerbation but a lasting increase in symptoms or impairment. This aspect is crucial because it demonstrates a direct link between the veteran's military service and the deterioration of their health.

To successfully support a claim for aggravation, evidence must be provided that shows the condition experienced a measurable worsening compared to the level of severity at the time of enlistment or induction. This could include medical records, lay evidence, or expert testimonies indicating changes in the condition's severity while the veteran was in service.

This requirement is in place to differentiate between natural progression of a condition, which may occur for various reasons unrelated to military service, and true aggravation that can be attributed to the time spent serving. The focus on service connection reflects the VA's commitment to ensuring that veterans receive care and benefits for service-related health issues.
