How do you pass the army medical?

In the army medical, you’ll be asked in detail about your medical history. Here’s what you need to know.

Pre-medical checks

Before you even get to the medical, you’ll be asked a long list of questions about your medical history.

Failing the medical is the second-most common reason that people don’t end up joining the army. (The most common reason, by the way, is that they decide the army’s not for them – most applicants to the army change their minds before they sign up, in fact.)

The army keeps a long list of medical problems. If you have any of these, you might not be able to join. Some medical problems will bar you from joining the army completely. Others mean waiting a year or two before joining. A few are not as serious and might not stop you from joining straight away, if the army doctor agrees to it. See the bottom of this page for the current list of medical conditions.

You’ll be expected to sign a form giving the army access to your medical records.

You’ll also be asked about drug use. If you’ve had an addiction problem then you’ll need to have been clean for three years. Current use of cannabis isn’t a problem, though you’ll be expected to stop before you sign up.

The medical

If you get through the pre-medical check and there are no other problems with your application, then you’ll go to the army’s Assessment Centre for a full medical check, as well as fitness tests.

In the full medical check, you’ll be tested for:

  • Healthy heart and lungs.
  • Good eyesight and hearing.
  • Strong joints and muscles.
  • Healthy weight.

You’ll be asked again about your medical history and the doctor will discuss with you any problems you’ve flagged up, or that appear on your medical records.

You’ll strip down to your underwear for the medical.

No part of the medical is painful and you’re not injected with anything.

If you’re later found to have lied about your medical history, the army will sack you.
