Social Media Health Misinformation: A Deadly Crisis Amid Regulatory Challenges

In the wake of a 23-year-old woman’s death from a treatable cancer, experts are sounding the alarm on the dangerous intersection of social media, health misinformation, and inadequate digital regulation.

Paloma Shemirani, 23, died after refusing chemotherapy for a treatable form of cancer, according to a recent BBC report. Her brothers have spoken out about their mother’s extreme anti-medicine beliefs that influenced Paloma’s decision to reject conventional treatment, highlighting how conspiracy theories amplified online can have fatal consequences.

The tragedy represents what health communication researchers describe as a systemic failure in our digital health information ecosystem. Dr. Christa Hodapp, author of “The Digital Health Self” and researcher on digital health communication, points to what she terms “a credibility crisis” shaped by platform capitalism and insufficient regulatory oversight.

“Social media platforms like Instagram, TikTok, and X have become de facto health information infrastructures,” explains Hodapp, whose recent research published in Anthropology & Medicine examines how these platforms function as unregulated public health forums. “Millions turn to these sites for advice, validation, and visibility, but the platforms themselves don’t prioritize clinical accuracy.”

Instead, these platforms operate within what researchers call the “attention economy of health” — a system where emotional appeal, aesthetic presentation, and algorithmic virality determine content reach rather than medical expertise. In this environment, credibility shifts from medical credentials and peer-reviewed research to follower counts and engagement metrics.

Paloma’s case exemplifies this troubling dynamic. The anti-medicine beliefs that influenced her treatment decisions weren’t isolated to obscure corners of the internet but rather part of a growing online health subculture that equates medical rejection with empowerment and natural remedies with moral superiority.

“These beliefs gain traction because they feel emotionally true and are framed as stories of self-reclamation,” notes Hodapp. “Platforms reward this type of content, creating a distorted credibility arena where influencers can market unproven therapies to millions with little oversight.”

The regulatory gap compounds the problem. Despite functioning as powerful public health platforms, social media companies face none of the standards for evidence, harm prevention, or ethical health communication that govern traditional health authorities like the NHS or WHO. This has created an alarming shift where platform visibility is mistaken for medical legitimacy.

Health communication experts also point to broader societal factors exacerbating the issue. In today’s social media landscape, individuals face pressure to perform health not only for personal wellbeing but for public display — proving their virtue through “Instagrammable” bodies and behaviors. In this context, rejecting conventional medicine can paradoxically appear as an act of autonomy or self-determination.

“This isn’t empowerment — it’s the product of a broken system,” says Hodapp. “If social media platforms continue to profit from health misinformation without regulatory intervention, we will see more preventable deaths.”

Health communication experts are calling for systemic changes, including robust regulation of health content, transparent algorithms, accountability standards for health influencers, and digital literacy initiatives that address both factual accuracy and the emotional dimensions of health misinformation.

The challenge extends beyond simply removing misleading posts. Rebuilding trust in evidence-based medicine requires confronting the emotional, cultural, and algorithmic forces that shape health beliefs in digital spaces.

As online health communities continue to grow in influence, medical authorities and technology companies face mounting pressure to address the credibility gap. Without meaningful intervention, experts warn that more vulnerable individuals may reject life-saving treatments based on misinformation encountered and reinforced through social media channels.

Paloma’s brothers hope their sister’s story will serve as a catalyst for change in how health information is regulated online, ensuring no other family experiences a similar preventable loss.
