Definition:
A "functional disorder" is a type of health problem where a person experiences symptoms (like pain, fatigue, or anxiety) but doctors cannot find a physical (anatomical) reason or clear cause for these symptoms. This means that the body appears normal when tested, but the person still feels unwell.
In more advanced discussions, you might find terms like "somatic functional disorder," which refers specifically to physical symptoms that have psychological origins.
While there are no specific idioms or phrasal verbs directly associated with "functional disorder," you might hear phrases like: - "In your head": This expression is sometimes used to imply that a person’s symptoms are psychological rather than physical. For example, "The doctor said my symptoms might be more in my head."
A "functional disorder" is a health issue where a person feels symptoms without any identifiable physical cause.
