So long as the therapist is trained and follows basic ethical norms, hypnotherapy is safe. Some people may feel dizzy or nauseous during or after being hypnotized. People who discuss traumatic memories may be subject to feelings of panic, flashbacks, or general feelings of anxiety, and the clinician or client may elect to discontinue treatment when symptoms are severe.
Since hypnotherapy is an adjunct form of therapy, used along with other forms of psychological or medical treatment, there are many applications. Hypnotherapy can be used to treat anxiety, phobias, substance abuse including tobacco, sexual dysfunction, undesirable spontaneous behaviors, and bad habits. It can be used to help improve sleep, learning disorders, communication, and relationship issues. Hypnotherapy can aid in pain management and help resolve medical conditions such as digestive disorders, skin issues, and gastrointestinal side effects of pregnancy and chemotherapy. It can also be used by dentists to help patients control their fears or to treat teeth grinding and other oral conditions.
