Introduction

TikTok has rapidly emerged as a significant platform for disseminating medical information. With its short-form, engaging videos and an algorithm that tailors content to user interests, TikTok reaches over one billion monthly active users worldwide (PMC, 2021). The platform has the unique capacity to convey health-related messages in an accessible manner. However, as the volume of health content grows, so do concerns regarding quality, accuracy, and the potential dissemination of misinformation. This research article examines the benefits and pitfalls of using TikTok for medical communication, explores the role of healthcare professionals, and highlights recommendations for ensuring reliable health information reaches users.

Background and Context

The Rise of Social Media in Health Communication

Social media is increasingly recognized as a powerful channel for healthcare communication. Platforms like TikTok have revolutionized how audiences receive and interpret medical information. Traditional media outlets are being supplemented—and sometimes replaced—by dynamic, user-generated content on platforms where the primary users are digital natives. The impact of this shift is profound, influencing both public perceptions of health information and patient behaviors.

As reported by numerous studies, TikTok’s growth is driven largely by its innovative algorithm, which promotes content that resonates with individual interests in ways that are both personalized and engaging (PMC, 2021; Wu et al., 2024). However, this same attribute that offers expansive reach also carries the risk of amplifying medically inaccurate content if stringent quality controls are not put in place.

TikTok’s Unique Characteristics for Health Communication

TikTok’s format—short videos ranging from 15 seconds to one minute—allows complex medical ideas to be communicated in a concise format. The platform also offers creative tools such as filters, text overlays, and editing features that make health information visually appealing and relatable.

The ease of sharing and the viral nature of content enhances the platform’s ability to spread both innovative health strategies and, unfortunately, misinformation. Given the predominantly youthful audience, this platform often serves as the first point of contact with medical information for many individuals.

Types of Medical Information on TikTok

Variety of Health Topics

TikTok features a diverse spectrum of medical information ranging from mental health advice and wellness tips to detailed explanations of chronic diseases and emerging public health issues. Common topics include:

Mental health awareness and self-care practices
Weight management and nutrition
Reproductive health, including abortion and contraception
Public health issues such as COVID-19 and vaccine information

Young adults, particularly those aged between 16 and 29, are often most engaged with content related to mental health and lifestyle improvements (KFF, 2024). However, while the platform hosts valuable educational material, it is also a site where compelling, yet inaccurate, narratives take root.

Quality and Accuracy of Information

The quality of medical information on TikTok varies significantly. Research indicates that videos produced by qualified health organizations and professionals tend to offer evidence-based advice, whereas content from non-expert sources or for-profit entities is more prone to inaccuracies and sensationalism (PMC, 2021; TechTarget, 2025). For example, studies evaluating content related to health conditions such as acne and diabetes have found that while there is high-quality material available, substantial portions of the videos contain incomplete or misleading information.

In one study, approximately 40% of health-related content was reported to include inaccurate or misleading information (TechTarget, 2025). This inconsistency raises significant concerns as TikTok’s primarily young audience may lack the experience to differentiate between credible sources and misinformation.

The Role of Healthcare Professionals

Engagement and Content Creation

Given the mixed quality of health information, the involvement of healthcare professionals on TikTok becomes essential. Medical professionals bring a level of authority and credibility that can counteract the spread of misinformation. Many healthcare experts have begun creating accounts dedicated to answering common medical queries and providing evidence-based health advice. A prominent example is an account that has accrued over one million followers by demystifying complex medical topics.

Furthermore, healthcare professionals are utilizing TikTok’s unique features such as "stitch" and "duet" to interact with and correct misleading content posted by other creators. By directly engaging with their audience, these professionals not only share accurate information but also empower viewers to critically evaluate health claims presented on the platform. Studies have shown that audiences are more likely to trust and act upon information delivered by verified medical experts (PMC, 2024).

Collaborative Initiatives and Partnerships

Recognizing the potential of TikTok as a vehicle for health education, several public health organizations and prominent entities like the World Health Organization (WHO) have entered into partnerships with TikTok. These collaborations aim to disseminate science-based information and boost the presence of legitimate health influencers. For instance, a 2024 initiative between WHO and TikTok seeks to leverage the platform’s broad reach to promote quality health information and counteract prevailing misinformation trends.

Such partnerships are designed to not only disseminate reliable information but also enhance the overall credibility of the health content ecosystem on TikTok. When healthcare institutions team up with social media platforms, content gains more visibility and offers a structured approach towards content moderation, ensuring that the most accurate and helpful information reaches the users.

Challenges in Health Communication on TikTok

Misinformation and Its Impacts

One of the greatest challenges on TikTok is the rapid spread of misinformation. Studies have shown that a significant percentage of health-related videos on the platform contain inaccurate or potentially harmful information (TechTarget, 2025). The virality of such content can have detrimental public health implications, especially when misinformation pertains to critical areas such as vaccine safety or the efficacy of medical treatments.

For example, videos promoting unverified cures or anti-vaccine narratives can influence public opinion and lead to harmful health decisions. The ease with which misinformation spreads is compounded by the platform’s algorithms, which do not always prioritize accuracy over engagement. Consequently, users who rely exclusively on TikTok for medical information may be at risk of being misled.

Content Moderation and Algorithmic Challenges

TikTok’s content moderation policies are continually evolving, yet the sheer volume of user-generated content makes comprehensive supervision challenging. The platform struggles to distinguish between creative, engaging content and that which propagates harmful misinformation. Furthermore, the algorithm’s bias towards sensational content often means that videos with provocative claims, even if incorrect, gain unwarranted traction.

These challenges necessitate a proactive approach from both the platform and its users. Enhanced verification systems for medical professionals, improved content flagging mechanisms, and stronger ties between public health organizations and TikTok can help mitigate these risks.

Opportunities for Enhancing Health Communication

Empowering Users Through Digital Literacy

One key strategy to combat misinformation on TikTok is the promotion of digital health literacy among users. By educating the public on how to identify credible sources, discern accurate information, and verify health claims, it is possible to reduce the influence of irresponsible content. Digital literacy programs and public awareness campaigns can empower users to make informed health decisions based on a critical evaluation of the information they encounter.

Leveraging Platform Features for Reliable Health Education

TikTok is continually evolving, adding new features that can be harnessed to promote reliable health information. Healthcare professionals and organizations can utilize tools like live streams, Q&A sessions, “duet” videos, and storytelling techniques that simplify complex medical data. These interactive formats allow for the adaptation of in-depth medical explanations into engaging content that retains factual accuracy while remaining accessible.

The integration of verified badges next to professional accounts also aids users in identifying trusted sources rapidly. This system of verification can significantly decrease the chances that inaccurate content will be mistaken for authoritative health advice.

Collaborative Campaigns and Community Engagement

Collaborative campaigns that involve public health organizations, reputable medical institutions, and trusted influencers can be highly effective in disseminating targeted health messages. Through coordinated campaigns, platforms can correct misinformation proactively and update users on important health developments. For example, an organized hashtag campaign focused on vaccine safety and efficacy can counterbalance misleading trends and provide viewers with comprehensive information sourced from multiple credible organizations.

Conclusion

TikTok’s explosive popularity has forged a new frontier in health communication, merging accessibility with creativity. Its ability to rapidly disseminate information makes it a valuable resource for public health outreach, particularly among young and diverse audiences. Nevertheless, this same characteristic also contributes to the widespread dissemination of misinformation. The dichotomy between opportunity and risk necessitates a multifaceted strategy that involves healthcare professionals, public health organizations, and informed users.

Engaging healthcare professionals in content creation, fostering collaborations between credible institutions and the platform, and empowering users through digital literacy initiatives are critical steps to safeguard the public from health-related misinformation. By continually refining content moderation practices and encouraging accurate, evidence-based narratives, TikTok can evolve into a trusted source for medical information. Future research should further explore innovative methods for quality control, the long-term impacts of social media-based health education, and effective ways to counter misinformation as digital communication continues to evolve.

In essence, while TikTok offers unprecedented opportunities for health education, ensuring the reliability of the medical information delivered is a shared responsibility that requires coordinated efforts between content creators, platform regulators, and the broader healthcare community.
