Hypnotherapy is a talking therapy that includes the use of therapeutic hypnosis, alongside other techniques. Hypnosis involves leading the client into a deep state of relaxation to communicate with their unconscious level thoughts and beliefs.

Hypnotherapists often see clients who want to reduce anxiety, stress or phobias, to improve confidence, exam performance, public speaking, or sports performance, to change unwanted behaviours such as smoking, or to address concerns over body image. Hypnotherapy is also widely used as a tool for pain management, including during childbirth and can be a valuable tool to help people reduce the effect of some health conditions that have a psychological component, such as Post Traumatic Stress Disorder, Tinnitus, Fibromyalgia and Chronic Fatigue Syndrome. The National Institute for Health and Clinical Guidance now recommends hypnotherapy as a treatment for persistent Irritable Bowel Syndrome that does not respond to prescription medication.
