As many as 80% of internet users seek health information online. The social determinants of health (SDoH) are intimately related to who has access to the internet and healthcare as a whole. Those who face more barriers to care are more likely to benefit from accessing health information online, granted the information they are retrieving is accurate. Virtual communities on social media platforms are particularly interesting as venues for seeking health information online because peers have been shown to influence health behaviour more than almost anything else. Thus, it is important to recognize the potential of social media to have positive mediation effects on health, so long as any negative mediation effects are reconcilable. As a positive mediator of health, social media can be used as a direct or indirect mode of communication between physicians and patients, a venue for health promotion and health information, and a community support network. False or misleading content, social contagion, confirmation bias, and security and privacy concerns must be mitigated in order to realize full potential of social media as a positive mediator of health. In any case, it is clear that the intersections between the SDoH, social media, and health are intimate, and they must be taken into consideration by physicians. Here, we argue that a paradigm shift in the physician-patient relationship is warranted, one where physicians: a) acknowledge the impacts of the SDoH on information-seeking behaviour, b) recognize the positive and negative roles of social media as a mediator of health through the lens of the SDoH, and c) use social media to catalyze positive changes in the standard of care.
