An emotionally-induced symptom tends to cause organic change if persisted long enough.
Clinical hypnotherapy – how to heal the mind to heal the body.
It has been acknowledged by many reputable medical men that more than seventy percent of human ailments are functional rather than organic. This means that the function of an organ or other part of the body has been disturbed by the reaction of the nervous system to negative ideas held in the subconscious mind. We do not mean to imply that every person who complains of an ailment is emotionally ill or neurotic. There are diseases caused by germs, parasites, viruses, and other things attacking the human body. However, we are a mind in a body and the two cannot be separated. Therefore, if you continue to fear ill health, constantly talk about your “nervous stomach” or “tension headaches,” in time organic changes must occur.
