Hypnotherapy is used for all psychosomatic disorders (mental and emotional states, which produce physical symptoms). Treatments can help with any problem you are finding hard to handle on your own, overwhelming or sustained emotional suffering or thoughts and actions you would like to banish or acquire as well as some physical problems. This is not an exhaustive list, but is designed to give an idea of the range of conditions that can be helped by hypnotherapy.
Broadly speaking, hypnosis is a naturally occurring phenomenon used widely throughout the world by many doctors, dentists, psychologists and psychotherapists. Often referred to as "trance" it is simply a mind skill - a way to communicate with the problem solving part of the human mind. If you think of trance as a mystical control state, where the recipient is unconscious, asleep or has had their mind "taken over", you would be absolutely wrong - there is no truth in this whatsoever. When used with psychotherapeutic techniques and suggestion, hypnosis can be a very effective form of treatment in the management of many disorders both physical and psychological.
