Functional symptom

A functional symptom is a medical symptom in an individual, which has no identified cause (etiology) despite extensive diagnostic assessments. By default, a functional symptom often is judged to have causes that are neither physical nor physiological, but rather psychological or psychiatric.¹

An example is functional constipation, which may have psychological or psychiatric causes. However, one type of apparently functional constipation, anismus, may have a neurological (physical) basis.
