There will probably be a few screening hints on the RN/RAF websites.
More common are:
Eyesight - no glasses and not colour blind.
Asthma - none for years (number unknown). Watch out for hayfever too.
Musclo-skeletal - no joint problems
anthropomorphics - must fit in most cockpit.
The authoritative document is AP1269A - but this is not available to the public.
Try the CAA website which does list most potential issues but beware that mil standards are different to Civ. In some cases more restrictive, in some cases less so. Don't ask me why.
