Chiropractic colleges and schools offer education and training in chiropractic health treatments. Teaching a broad spectrum of topics of diagnostics and treatment for persons suffering from muscular, nervous and skeletal system problems; chiropractic colleges and schools stand strong on firm belief that interference within these systems can disrupt normal functioning and lowers resistance to disease. Chiropractic colleges and schools are holistic educational systems that place emphasis on patient's overall well-being. By evaluating numerous factors such as one's exercise, diet, rest, environment and heredity; chiropractic colleges and schools teach prospective physicians to use natural, drug-free, non-surgical health treatments that rely on body's self-healing mechanisms.
