Health experts are sounding the alarm over the spread of medical misinformation on social media platforms, where content about allergies and asthma often gains popularity based on engagement rather than accuracy, according to new research presented at the American College of Allergy, Asthma and Immunology (ACAAI) Annual Scientific Meeting in Orlando.
Two separate studies examined how health information circulates on popular platforms like TikTok, revealing a concerning pattern where inaccurate content frequently receives more attention than medically sound advice, potentially putting patients at risk.
In the first study, researchers analyzed the top 100 videos using the hashtag “alphagal” on social media. Alpha-gal syndrome (AGS) is an increasingly prevalent condition caused by Lone Star tick bites that can trigger severe allergic reactions when patients consume red meat. Despite the technical nature of this condition, only 15 of the most popular videos came from physicians, and few of those were created by allergists specifically trained in the condition.
“Alpha-gal is confusing for patients, and many turn to social media for guidance. While personal stories are valuable, there’s also a lot of misinformation,” explained Dr. Nadia Hamid, an ACAAI member, allergist and lead author of the study. “When allergists and other doctors step in, their content resonates – suggesting a real opportunity to improve public understanding.”
The study found that while most content creators sharing alpha-gal information were non-physicians posting shorter, anecdotal videos, physician-created content generally received higher engagement through likes and comments. This suggests patients are actively seeking credible medical expertise on the platform, creating an opening for specialists to provide accurate information in an accessible format.
Even more concerning patterns emerged in the second study, which examined TikTok content about asthma, a condition affecting over 25 million Americans. Researchers evaluated the 40 most-liked English-language videos posted in 2024 under the hashtag “asthma” and discovered that more than one in four contained inaccurate or misleading claims.
These inaccuracies weren’t harmless. Some videos falsely claimed asthma could be cured through breathing exercises alone, while others spread dangerous myths, including the potentially fatal combination of caffeine with asthma medications. Despite their inaccuracy, these misleading videos garnered over three times more likes than medically accurate content.
“TikTok and other platforms offer incredible opportunities to reach patients where they are,” said Dr. Ishitha Jagadish, medical resident and lead author of the asthma study. “But right now, misinformation about asthma is not only widespread, it’s more engrossing than accurate content. We need more allergy and asthma experts online to present science-based, engaging content.”
The findings highlight a growing public health challenge in the digital age. As social media platforms continue to serve as primary information sources for millions of people seeking health guidance, the absence of medical professionals in these spaces creates a vacuum often filled by well-meaning but uninformed content creators or those promoting unproven remedies.
This pattern is particularly concerning for conditions like alpha-gal syndrome, where diagnosis is complex and treatment protocols are still evolving, or asthma, where proper management is essential to prevent potentially life-threatening attacks.
The research suggests a critical need for medical professionals, particularly specialists, to establish stronger presences on social platforms where patients already gather. When physicians do create content, the studies show patients engage more readily with it, suggesting a hunger for credible information presented in accessible formats.
For patients, the findings underscore the importance of verifying health information found on social media with healthcare providers and seeking out content created by medical professionals rather than relying solely on popularity metrics like likes or shares to determine accuracy.
As these platforms continue to shape public health understanding, the research serves as a call to action for the medical community to meet patients where they are—online—with accurate, engaging content that can compete with the viral appeal of medical misinformation.
