Discrimination of persons living with obesity by healthcare professionals

Obesity is a highly prevalent and complex condition with biomedical, psychological, and social dimensions that pose major challenges for healthcare systems. Beyond its clinical consequences, people living with obesity frequently experience weight-based discrimination in healthcare settings, undermining care quality and equity. This paper examines key mechanisms underlying obesity-related stigma among healthcare professionals, including attribution of excess weight to individual responsibility and the internalization of stigma by patients. Drawing on current evidence, it analyses how negative attitudes of healthcare professionals contribute to suboptimal clinical interactions, inadequate care environments, and reduced patient engagement. These processes may weaken the therapeutic relationship, hinder treatment adherence, and negatively affect physical and mental health outcomes. Addressing obesity stigma requires targeted professional training, adaptation of care environments, and inclusive health policies to ensure equitable and respectful care for this population.
