1. Picture a young parent at 2 a.m., wide awake in the dim glow of a phone, scrolling past a dozen frantic posts about fevers, rashes, vaccines, and feeding schedules. They are not alone in the room, perhaps, but they feel alone in the worry. The health visitor who once might have made a home visit is stretched thin or simply no longer assigned. The GP appointment is a distant three-week wait. So they turn to the one thing that never sleeps: social media. It is there, in that vulnerable hour, that public health messaging is won or lost. This is the new reality that Dr. Lillie Parker, a paediatrician with more than 100,000 Instagram followers, wants healthcare leaders to understand. Speaking at the UK Health Security Agency (UKHSA) Conference in Manchester, she made an urgent and human case for embracing medical professionals as content creators. Her message is simple but profound: healthcare institutions have spent years posting polished carousels and official infographics, but people are starving for connection, not information. “Humans are craving human interaction,” she said. At a time when the healthcare system is pulling away from communities—with fewer health visitors and GPs—the smartphone remains in every pocket. And that, she argues, is where public health must meet people. Not with sterile corporate accounts, but with the real, reassuring faces of clinicians who are already trusted in their surgeries and now need to be trusted on screens.
2. The backdrop to Dr. Parker’s appeal is a healthcare system under immense strain. Families are navigating parenthood with less professional support than ever before. Health visitors, once a routine lifeline for new mothers, have been cut back dramatically across the UK. GPs, too, are becoming scarcer, with longer waits and squeezed resources. In that gap, a torrent of online misinformation has rushed in. Parents today have access to more information than any generation in history, but as Dr. Parker observed, it is not empowering them. Instead, it is overwhelming them. “Far from empowering parents, I’ve found that it’s been very overwhelming for people,” she explained. It is creating a generation that is more anxious and feels more pressure than ever to get things right when it comes to children’s health. This is where her role as an influencer becomes something more than vanity or side-hustle. She is filling a vacuum left by the retreat of state-funded care. But she is doing it on her own time, often free of charge. In her address, she challenged public health bodies to recognise that a carousel post of text from an organisation is not what the public will engage with. “In that 1.8 seconds they are going to scroll past, they will not be reading what you have to say,” she told delegates. Organisations like UKHSA and the World Health Organisation, she argued, already seem to recognise the need for human messengers—perhaps more clearly than NHS England does. But even they need to go further. The key, she insisted, is to understand that human beings are the route to the public, even if they are human beings on a screen.
3. Dr. Parker did not set out to become a medical influencer. A self-described NHS clinician first and always, she started her page around three years ago for deeply personal reasons. Friends and family who were having children were becoming lost in the noise of parenting advice, much of it conflicting and some of it dangerously wrong. She watched them spiral into anxious late-night research, questioning every decision, doubting every instinct. “I think we all know that parents have access to more information than ever before,” she reflected, “but actually, far from empowering parents, I’ve found that it’s been very overwhelming.” Her response was to start posting answers, myth-busting, and gentle reassurance under the handle doctor.lils. The response was immediate and profound—not because she was sharing groundbreaking science, but because she connected as a person. She spoke like a doctor who had sat with crying babies and exhausted mothers, not a faceless agency. Her account grew quickly, passing 100,000 followers, but that growth came at a personal cost. She told the conference that she now works only 60 per cent of her time for the NHS and spends the rest of her energy creating content. “I don’t get paid for the rest of the time,” she said. “But I’m doing it for free because I’m passionate about what I do. So why can’t it be part of my job? I would love that.” Her story raises a difficult question for the healthcare system: if we expect clinicians to fight misinformation, should we not pay them for it?
4. There is an uncomfortable tension in medicine around social media. Doctors are trained in communication—how to break bad news, how to listen, how to explain complex science in plain language. Yet the idea of a clinician posting online for the public still triggers an underlying anxiety. Dr. Parker acknowledged this during her talk. “There is an anxiety around those people being on social media,” she said. Some of that fear is understandable. The internet is unforgiving, and the line between helpful advice and individualised medical guidance can blur. There are concerns about accountability, privacy, and the misuse of professional title. But Dr. Parker argues that this anxiety is becoming outdated. The medical profession already communicates with the public every day, and doctors are uniquely placed to translate evidence into everyday language. The reluctance to embrace social media is more about institutional caution than about patient safety. By avoiding platforms like Instagram and TikTok, healthcare organisations are ceding ground to quacks, wellness influencers, and doom-mongers. The result is that parents are receiving contradictory messages from strangers with no medical training, while the voices of trained paediatricians remain quiet, muffled by fear of getting it wrong. If we truly care about combating misinformation, Dr. Parker’s message is that we must normalise and even formalise the clinician-influencer role, giving doctors time, support, and compensation to do what they are already doing in their spare time.
5. The need for this shift is becoming urgent. Earlier in the summer, NHS England launched its own account on TikTok, a move seen as a reluctant acknowledgment that the public has moved on from leaflets and public service announcements. The step followed a blunt warning from national medical director Professor Frankie Swords that people are seeking out health information from “unreliable” sources. But launching a TikTok account is not the same as building trust. An account run by a communications team, no matter how polished, is still an institution speaking from behind a logo. What works, Dr. Parker insists, is human beings. She urged organisations to “use the content creators that are already there” rather than starting from scratch. The most effective public health strategy, she proposed, is partnership: identify trusted medical voices who already have audiences, support them, amplify them, and compensate them. This is not about vanity metrics or chasing viral moments. It is about building a distributed network of credible, relatable health communicators who can reach people where they already are. The WHO and UKHSA, she noted, are already realising this. They understand that a human voice can break through the algorithm in a way that a corporate statement cannot. What remains to be seen is whether the wider NHS and government will follow suit, with funding and formal recognition for what is effectively a new form of front-line public health work.
6. Ultimately, Dr. Parker’s call to action is not just about social media strategy; it is about the kind of healthcare system we want to build. For decades, we have relied on physical infrastructure—hospitals, clinics, appointment systems—to deliver health advice. But the internet has changed where people seek guidance, and the pandemic proved how quickly misinformation can spread. The healthcare system cannot simply lament the decline of face-to-face contact; it must adapt to the world as it is, not as it wishes. That means seeing social media not as a distraction from clinical work, but as a central part of it. It means valuing doctors who can translate medicine into viral, empathetic content in the same way we value those who publish research or teach medical students. And it means recognising that behind every screen is a human being, often anxious, often tired, looking for someone to tell them it will be okay. Dr. Parker is already doing that work, unpaid, because she believes in it. But her voice should not have to be a hobby. It should be part of the health service’s armour against misinformation. The public are craving human interaction, she reminds us. They are craving people who listen, explain, and care. In a world of shrinking healthcare budgets and rising online noise, the most powerful tool we may have is not a new app or a new policy—it is the compassion of a doctor, held up to a camera, saying, “I see you, and here is how we will get through this together.” That is the future of public health, and it is time our institutions caught up with it.
