F45.0 Somatization Disorder Differential Diagnosis
Medical conditions may be confused with somatoform disorder especially early in their course (multiple sclerosis, brain tumor, hyperparathyroidism, hyperthyroidism, lupus erythematosus).
Further investigation or consultation should be considered in long-term somatization disorder if there is a shift in the emphasis or stability of the physical complaints. This change in symptoms suggests possible development of physical disease.
Affective (depressive) and anxiety disorders accompany somatization disorders but need not be specified separately unless they are sufficiently marked and persistent.
