Since 2001, over 2 million United States military men and women have deployed as part of Operation Iraqi Freedom and Operation Enduring Freedom. In the past few years, evidence has emerged that U.S. military personnel who have deployed to Iraq and Afghanistan may be at increased risk for developing lung symptoms and, in some cases, disabling chronic lung diseases including asthma and constrictive bronchiolitis. The causes of their lung diseases remain unknown, but may be related to exposure to dangerous chemicals and inhalation of small fragments of substances in the Southwest Asia environment.
Military personnel deployed in Southwest Asia are exposed to emissions from:
open-air burn pits – chemicals, metals, combustion products
desert dust and sand storms
industrial fires and emissions
temperature and humidity extremes in the desert climate.
Individual factors (such as smoking status) may also contribute to lung disease risk.
Types of Possible Deployment-Related Lung Diseases
The post-deployment lung diseases that have been reported include:
Returning soldiers from Iraq and Afghanistan may report lung symptoms including:
exertional dyspnea (shortness of breath with exercise)
decreased exercise capacity
mucus membrane and eye irritation.
Further examination by a doctor is often needed to properly diagnose post-deployment lung diseases.
Screening and Diagnosis
Diagnostic testing of those with post-deployment lung symptoms may include:
Those who have asthma, rhinitis, or bronchitis should be treated based on standard guidelines.
To date, there are no studies offering specific recommendations for medical management of those affected by post-deployment lung diseases. As a result, the Center of Excellence on Deployment-Related Lung Disease at National Jewish Health has been established to help identify causes, treatment and prevention.
