Sleep apnea and weight gain from a service-connected condition
· Claim Situation
The situation
A common sleep apnea denial says obesity, not service, caused it. Obesity itself isn't a disability, but it can be an intermediate step between a service-connected condition and sleep apnea.
The intermediate-step theory
VA's General Counsel (VAOPGCPREC 1-2017) said obesity can be an intermediate step: a service-connected condition causes weight gain, which causes or aggravates apnea. It still needs medical evidence (38 CFR 3.310).
Ask: what took the activity away?
- Knee, back or foot conditions limiting exercise.
- PTSD or depression and medications linked to weight gain.
- Thyroid or other conditions.
Document the timeline
- Weight from separation to diagnosis.
- When activity dropped and why.
- Medication start dates.
Other routes
- Secondary to mental health.
- Secondary to sinus or airway conditions.
- Direct with in-service witness statements.
