"If someone wishes for good health, one must first ask oneself if he is ready to do away with the reasons for his illness. Only then is it possible to help him." ~ Hippocrates
Your mind and body are linked, which can't be seen, but only felt. Your body reflects your emotional and psychological states. A positive mental attitude and powerful immune system will be the result of a healthy spiritual, physical and emotional state. It is only when we ignore our bodies that illness is able to take control of our own bodies natural defenses.
Your thoughts and feelings are linked to specific parts of the body and different illnesses. When you fall sick, the body is communicating that your way of thinking (unconscious) is out of sync with what is beneficial to our being. Your body is asking you to live in harmony, at peace with your self and your surroundings.
I came across this emotional chart which shows the mental thought patterns that form our daily experiences. It is also part of the book, "Heal Your Body" by Louise Hay – where she has listed all the common illnesses and diseases with the possible metaphysical cause.
