Traveling for medical care in a global world.

The international medical travel of Yemenis provides insight on terminology and models to use for the growing global phenomenon. Terminology for medical travelers ranges from "medical tourists" to "medical exiles." Differing models prioritize the global arena in which transnational medical travel occurs as (1) a global medical marketplace, (2) a global medical commons, (3) interlinked nation-states, and (4) national or global citizens. Medical anthropology has a specific role in uncovering the lived experiences of patients who travel to often unfamiliar destinations to pursue care believed capable of alleviating suffering.
