Lesbian, gay, bisexual and transgender (LGBT+) young people face several challenges in their daily lives, including specific healthcare inequalities. Negative societal attitudes towards sexual and gender minorities, and the effects of regular experiences of bullying and homophobia/transphobia exacerbate the normal trials and tribulations of childhood and adolescence. Barriers to accessing healthy activities, such as sport, are created by perceived stigma and real-life experiences. Healthcare environments are by default heteronormative and contribute to the isolation and exclusion of LGBT+ young people. Paediatricians are well placed to act on these healthcare inequalities and to advocate for LGBT+ youth, through simple changes to individual practice as well as system-wide improvements.
