Medical certificates

You can apply for a medical exemption certificate if you have one of the following medical conditions:

• a permanent fistula (for example, caecostomy, colostomy, laryngostomy or ileostomy) which needs continuous surgical dressing or an appliance
• a form of hypoadrenalism (for example, Addison’s Disease) for which specific substitution therapy is essential
• diabetes insipidus and other forms of hypopituitarism
• diabetes mellitus, except where treatment is by diet alone
• hypoparathyroidism
• myasthenia gravis
• myxoedema (that is, hypothyroidism which needs thyroid hormone replacement)
• epilepsy which needs continuous anticonvulsive therapy
• a continuing physical disability which means you cannot go out without the help of another person
• cancer and are undergoing treatment for either:
  - cancer
  - the effects of cancer
  - the effects of cancer treatment

These are the only conditions that entitle you to a medical exemption certificate. If you’re not sure about the name of your condition, speak to your doctor.
