Health care for people who identify themselves as part of the LGBT+ community is negatively affected by heteronormativity, which has historically ruled our society. The marginalization of this group of society in our health care system stands out. Its causes are different discriminations and violations of LGBT+ people's rights, which become health barriers. The objective of this research was to know the health care experience of LGBT+ adults from Concepción. Semi-structured interviews were carried out, in the context of a qualitative research, through the use of Grounded Theory. Four main categories emerged from the coding of the 6 interviews, corresponding to “Heteronormativity”, “Disinformation from health care professionals”, “Disinformation about patients' rights and duties” and “Diversity acknowledgement”. It is concluded that health care professionals' training is of the upmost importance, as much as social participation of the LGBT+ community. Both together act as strategies to overcome LGBT+ population inequalities and marginalization, in the context of health care.
