A medical certificate is required for expedition participants who are 66 years of age or older or have a disability or medical condition(s). The medical certificate must document their suitability to complete the journey and their ability to cope with the hardships of, for example, desolate and climatically difficult areas.

In connection with the use of medication, the information provided in an application must include a medical professional assessment of whether the medication can be stored and taken at extreme temperatures without impairing its effectiveness.

The obligation to provide documentation for one's state of health must take the form of a medical certificate. The medical certificate must meet the following conditions:

1. The medical certificate must contain information about the applicant's disability and special medical conditions.
2. The medical certificate must document the applicant's suitability to carry out the planned journey within the geographical area covered by the Executive Order on Travel.
3. The medical certificate must contain information on the measures the applicant has taken or must observe with a view to countering any problems with illness, disability or age-related impairment.
4. The medical certificate must not be older than 3 months from the date of issue when submitted to the Expedition Office.

Background for the requirement for documentation
Medical science has documented that the changes and transitions that occur as people age are complex in nature. Purely biologically, with ageing, a gradual accumulation of a number of molecular and cellular changes is seen, whereby over time a decline in functional level and an increased risk of disease is seen. Thus, generally speaking, from around the age of 60 there is a sharp increase in the extent of functional limitations in relation to, for example, hearing, sight and movement, as well as chronic diseases, such as cardiovascular diseases, chronic respiratory diseases, cancer and dementia. This is not an exhaustive list, but simply examples of diseases and conditions that risk affecting people who have reached an advanced age.

Facts of i.a. this type has been used as a basis by the Government of Greenland in connection with the determination of criteria for when requirements for documentation of suitability to carry out a planned journey must be met by an expedition participant, cf. section 7, subsection 2 of the Executive Order on Travel.
