The consultation will include information about what action should be taken when students' health problems impact on patient safety.
Medical schools will be called on to provide medical students with the opportunity to seek support before poor health becomes a fitness-to-practice concern.
It will also ask for views about how the GMC can support the implementation of the guidance and how to improve the consistency of decision-making on student fitness to practice within and between medical schools.
Professor Peter Rubin, chairman of the GMC education committee, said: ‘Students' behaviour at all times must justify the trust the public places in the medical profession.
‘We hope that our amended guidance makes it clear what standards of professional behaviour are expected but also that there should be support for those students with difficulties in meeting these expectations for whatever reason.'
The consultation closes on 19 September. Once finalised, the guidance will be adopted by medical schools across the UK.
