Chiropractic is based on the principle that the body is highly intelligent; the body is aware of what needs to be done in order to adapt to the stressors of the environment and everyday life, as well as of how to recover from an injury or disease.
Now, imagine the nervous system as the top supervisor of all the processes happening in the body. If this system gets disrupted, then the communication system of the body breaks down. This results in a body malfunctioning which may gradually lead to almost any condition imaginable. Chiropractic does not form as a treatment of these conditions, though it aims to the communication failure through adjustments of the spine, in order to allow the body to function properly.
