From previous replies, it seems that aircrew medical standards will not affect you. Although you may have to pay to see the ICAO document, the UK CAA (JAR compliant) one is available gratis at
JAR Class 1 and 2 medicals | Medical | Safety Regulation
Do you hold a UK driving licence? If yes, then contact with potential employers in your intended field would be a worthwhile step.
Good luck!
Oops! Just noticed your age, so I suppose you do not yet have a driving licence. See
Medical information for relevant guidance. At this stage, if anything remains unclear, see your GP to discuss it.
