Service Connection by Aggravation
Aggravation can describe either worsening of a preexisting condition during service or worsening of a non-service-connected condition by a service-connected disability.

Quick answer
“Aggravation” is used in two different VA contexts. One concerns a disability that existed before service and increased during service. The other is secondary aggravation, where a service-connected disability worsens a separate condition. Mixing the two can make the evidence plan unclear.
Preexisting condition aggravated during serviceDetails
- Identify reliable evidence of the condition before entry, including what was recorded at entrance.
- Document the level and course of the condition during service.
- Show the actual increase in disability, not only a temporary symptom flare when the evidence indicates no lasting increase.
- VA applies rules concerning the presumption of soundness and natural progression; these issues can be legally complex.
Secondary aggravation after serviceDetails
- Confirm the primary disability is already service connected.
- Confirm the aggravated condition is a separate current disability.
- Obtain competent evidence addressing whether the service-connected disability produced additional worsening beyond natural progression.
- Evidence of the condition’s baseline and later severity may be important to the evaluation of aggravation.
Evidence to organizeDetails
- Entrance, service, separation, and post-service medical records.
- A chronological description of symptoms, treatment, and functional change.
- Medical opinions that identify which aggravation theory they address and explain the reasoning.
- Records that discuss other likely causes or natural progression rather than ignoring them.
Common questionsDetails
- Does any worsening during service prove aggravation? — Not automatically; the regulation distinguishes an increase in disability from findings attributed to natural progression.
- Is a temporary flare always aggravation? — A brief flare alone may not establish lasting worsening; the complete disability history matters.
- Can aggravation apply to a secondary claim? — Yes, under a different regulation and framework from in-service aggravation.
