Any therapeutic treatment that does not address the underlying cause of a disorder can and will most often lead to symptom substitution. For instance, if one is feeling depressed due to strong feelings of abandonment rooted from their personal history, and they do not address this as being the cause, the depression will more often than not manifest in some other disorder. If the therapeutic diagnosis is something like "improve you lifestyle by eating right and exercising", this may improve a person's overall mood and help tremendously, but will not address the unresolved problems in this person's past. As a result, they may become absolutely fixated on living a healthy lifestyle to the point that it turns into a paranoid obsession. And thus arises another problem, and the symptoms of depression become symptoms of obsession.

Psychiatrists and psychotherapists often work together to provide the best possible treatment for a patient.
