People who serve in the military and veterans face some different health issues than civilians. During wartime, the main health concerns are life-threatening injuries. These include shrapnel and gunshot wounds, lost limbs, and head injuries. Some service members might also have health problems from exposure to environmental hazards, such as contaminated water, chemicals and infections.

Service members and veterans are at risk for mental health problems, too. These include anxiety, post-traumatic stress disorder, depression and substance abuse.
