This present article was constructed from an empirical work of intervention-research in a support group for transgender people which worked at the Clínica de Psicologia Aplicada (CPA) [Applied Psychology Clinic] of the Universidade Federal de Juiz de Fora (UFJF), in Minas Gerais, Brazil. It aimed at analyzing psychosocial aspects of the interventions that such people made to their bodies, investigating process of health and sickness involved in these contexts. The analysis of the participants’ reports of the support group identified itself with a deep relation between the construction of the bodies and subjectivities of travesty and transgender people belonging to the lower classes and the utilization of the Brazilian public health system, called Unified Health System (SUS). As results, it found that in Brazil, the travesty and transgender population is neglected when accessing the public health services, which causes many damages and, in some cases, irretrievable consequences to the health of these people. The treatment model in the public health system in Brazil concerning the travesty and transgender population is reductionist and precarious, considering health only under the biological view and disregarding the complexity of this phenomenon. This way, SUS neglects the psychic losses that transgender brings related to their bodies, something which contradicts the broad health concept defined by the World Health Organization (WHO).
