Hypnotherapy is a therapeutic approach that makes use of hypnosis to help a person make positive changes to their ideas, feelings, and behaviours. It entails putting the subject into a trance, a relaxed state of sharpened attention and concentration where they are more receptive to ideas and insights. 

Hypnotherapy seeks to address a range of problems through this procedure, including anxiety, phobias, quitting smoking, managing weight, and boosting self-confidence. It can help explore and reprogram subconscious patterns, leading to personal transformation and improved well-being.
