You're a doctor. You're also a person with opinions, a social life, and an online presence. The GMC says you must maintain public trust in the profession at all times — including online. But the guidance on what that actually means in practice is vague enough to make every doctor slightly anxious about posting anything at all.
Here's the practical interpretation.
What the GMC actually says
The GMC's guidance on social media and online behaviour falls under "Good Medical Practice" and supplementary guidance on "Doctors' Use of Social Media." The core principles:
You must not post anything that could undermine public confidence in the medical profession. You must not breach patient confidentiality (including indirect identification). You must not bully, harass, or make discriminatory comments. You should be honest about your identity and qualifications if commenting in a professional capacity.
These principles are deliberately broad. They don't say "don't use Twitter." They say "use it in a way that maintains trust."
What's actually fine
Discussing medical topics. Sharing medical education content, discussing clinical guidelines, debating health policy, correcting health misinformation — all fine. This is arguably a professional obligation, not just a permission.
Having opinions. The GMC doesn't require you to be politically neutral. You can express views on health policy, workforce issues, NHS funding, and other matters of public interest. Thousands of doctors do this daily on social media. The boundary is between opinion (fine) and conduct that undermines trust (not fine).
Being a normal person online. Posting about your hobbies, your holidays, your dog — all fine. You don't surrender your personality when you register with the GMC.
Discussing your own experiences. Talking about burnout, difficult career decisions, or the emotional reality of being a doctor — fine, and increasingly valued as part of the professional conversation. The "doctors should be stoic and silent" era is over.
What's risky
Anything that could identify a patient — even indirectly. The classic mistake: posting about an interesting case without explicit details but with enough context that someone who knows the patient could identify them. "Saw an amazing case today — young man, unusual presentation of X condition, came in via Y hospital" can be identifiable if the case is rare and the hospital is named. The rule: if there's any possibility of identification, don't post it. "Interesting case today" with no clinical details is fine. Any clinical details push you toward risk.
Inflammatory language about colleagues, institutions, or patients. You can criticise a policy. You shouldn't call a specific colleague incompetent in a public forum. You can express frustration with NHS systems. You shouldn't mock individual patients, even anonymously.
Responding to patients online. If a patient contacts you through social media, don't engage clinically. Direct them to appropriate clinical channels. Any clinical advice given through social media creates a duty of care with no documentation, no confidentiality, and no governance.
Drunk posting, rage posting, or late-night posting. The post you write at 11pm after a terrible shift is the post most likely to cause you problems. The advice that sounds obvious but isn't followed: if you're angry, tired, or intoxicated, don't post.
Cases that have led to trouble
The GMC has investigated and sanctioned doctors for social media conduct in a number of published cases. Common patterns:
Posting identifiable patient information (even when the doctor believed it was anonymised). Posting sexually explicit content linked to a professional identity. Sustained online bullying of colleagues. Posting discriminatory content. Presenting misleading health claims as medical expertise.
The threshold is higher than most doctors fear. The GMC is not monitoring your Instagram for holiday photos or your Twitter for opinions about GP funding. It investigates when complaints are made — and complaints are made when content is genuinely offensive, identifiable, or undermines trust in a way that a reasonable member of the public would find concerning.
Practical guidelines
Assume everything is public and permanent. Private accounts aren't private. Screenshots exist. Content you delete can be recovered. Post accordingly.
Separate personal and professional if you prefer. Some doctors maintain separate accounts — one professional, one personal. This isn't required but reduces risk for those who want to be freely personal online.
Identify yourself honestly. If you're commenting on medical matters and your audience would reasonably assume you're speaking as a doctor, don't pretend otherwise. Using your credentials to add authority to a non-medical opinion (e.g., "as a doctor, this political party is wrong about...") is a grey area — use judgement.
Don't give specific medical advice to individuals online. General health education: fine. "Based on what you've described, you should take X medication": not fine.
When in doubt, don't post it. Or at least wait 24 hours. If it still seems like a good idea after a night's sleep, it probably is.
