Hypnotherapy has been studied for the treatment of irritable bowel syndrome.[117][118] Hypnosis for IBS has received moderate support in the National Institute for Health and Clinical Excellence guidance published for UK health services.[119] It has been used as an aid or alternative to chemical anesthesia,[120][121][122] and it has been studied as a way to soothe skin ailments.[123]
Milton Erickson (1901–1980), the founding president of the American Society for Clinical Hypnosis and a fellow of the American Psychiatric Association, the American Psychological Association, and the American Psychopathological Association, was one of the most influential post-war hypnotherapists. He wrote several books and journal articles on the subject. During the 1960s, Erickson popularized a new branch of hypnotherapy, known as Ericksonian therapy, characterised primarily by indirect suggestion, "metaphor" (actually analogies), confusion techniques, and double binds in place of formal hypnotic inductions. However, the difference between Erickson's methods and traditional hypnotism led contemporaries such as André Weitzenhoffer to question whether he was practising "hypnosis" at all, and his approach remains in question.
Sessions with a Professional Hypnotherapist can relieve stress, insomnia and physical discomfort, change negative or limiting habits and beliefs, improve self esteem, confidence, motivation, creativity, learning, and memory. And there are many other challenges people face in their lives that can be changed or eliminated with hypnosis, including the 2 more well known reasons people contact a hypnotist, stop smoking hypnosis and hypnosis weight loss.
Hypnosis is normally preceded by a "hypnotic induction" technique. Traditionally, this was interpreted as a method of putting the subject into a "hypnotic trance"; however, subsequent "nonstate" theorists have viewed it differently, seeing it as a means of heightening client expectation, defining their role, focusing attention, etc. There are several different induction techniques. One of the most influential methods was Braid's "eye-fixation" technique, also known as "Braidism". Many variations of the eye-fixation approach exist, including the induction used in the Stanford Hypnotic Susceptibility Scale (SHSS), the most widely used research tool in the field of hypnotism.[33] Braid's original description of his induction is as follows:

Hypnosis has long been considered a valuable technique for recreating and then studying puzzling psychological phenomena. A classic example of this approach uses a technique known as posthypnotic amnesia (PHA) to model memory disorders such as functional amnesia, which involves a sudden memory loss typically due to some sort of psychological trauma (rather than to brain damage or disease). Hypnotists produce PHA by suggesting to a hypnotized person that after hypnosis he will forget particular things until he receives a “cancellation,” such as “Now you can remember everything.” PHA typically only happens when it is specifically suggested and it is much more likely to occur in those with high levels of hypnotic ability, or “high hypnotizable” people. Now a new study shows that this hypnotic state actually influences brain activity associated with memory.

Controversy surrounds the use of hypnotherapy to retrieve memories, especially those from early childhood or (supposed) past-lives. The American Medical Association and the American Psychological Association caution against recovered-memory therapy in cases of alleged childhood trauma, stating that "it is impossible, without corroborative evidence, to distinguish a true memory from a false one."[144] Past life regression, meanwhile, is often viewed with skepticism.[145][146]

“Before attending the Hypnotherapy Academy of America, I had already had over 500 hours of hypnotherapy training; however, I felt that I was missing some important concepts and skills, so I went to the Academy hoping to get what I was unable to get from other training. My goals were completely fulfilled. I received a solid foundation in hypnosis and hypnotherapy and learned how to take hypnotherapy to new heights and greater depths. As a result of the Academy training, I now do hypnotic work more efficiently and more effectively than with my prior training. Because the quality of my work as a hypnotherapist has significantly improved through the Academy training, I can offer greater value to my patients, and I can more easily market my practice.

Ernest Hilgard, who developed the "neodissociation" theory of hypnotism, hypothesized that hypnosis causes the subjects to divide their consciousness voluntarily. One part responds to the hypnotist while the other retains awareness of reality. Hilgard made subjects take an ice water bath. None mentioned the water being cold or feeling pain. Hilgard then asked the subjects to lift their index finger if they felt pain and 70% of the subjects lifted their index finger. This showed that, even though the subjects were listening to the suggestive hypnotist, they still sensed the water's temperature.[180]
Preliminary research has expressed brief hypnosis interventions as possibly being a useful tool for managing painful HIV-DSP because of its history of usefulness in pain management, its long-term effectiveness of brief interventions, the ability to teach self-hypnosis to patients, the cost-effectiveness of the intervention, and the advantage of using such an intervention as opposed to the use of pharmaceutical drugs.[91]

Researchers have used PHA as a laboratory analogue of functional amnesia because these conditions share several similar features. Case reports of functional amnesia, for instance, describe men and women who, following a traumatic experience such as a violent sexual assault or the death of a loved one, are unable to remember part or all of their personal past. However, as in PHA, they might still show “implicit” evidence of the forgotten events. For instance, they might unconsciously dial the phone number of a family member whom they can’t consciously recall. (In contrast, explicit memories are those we consciously have access to, such as remembering a childhood birthday or what you had for dinner last night.)  And, as suddenly as they lost their memories, they can just as suddenly recover them.
For some psychologists who uphold the altered state theory of hypnosis, pain relief in response to hypnosis is said to be the result of the brain's dual-processing functionality. This effect is obtained either through the process of selective attention or dissociation, in which both theories involve the presence of activity in pain receptive regions of the brain, and a difference in the processing of the stimuli by the hypnotised subject.[137]
Although there are different techniques, clinical hypnotherapy is generally performed in a calm, therapeutic environment. The therapist will guide you into a relaxed, focused state and ask you to think about experiences and situations in positive ways that can help you change the way you think and behave. Unlike some dramatic portrayals of hypnosis in movies, books, or on stage, you will not be unconscious, asleep, or in any way out of control of yourself. You will hear the therapist’s suggestions, but it is up to you to decide whether or not to act on them.
