Other uses of hypnotherapy

The success rate for habit control is varied. A meta-study researching hypnosis as a quit-smoking tool found it had a 20 to 30 percent success rate, while a 2007 study of patients hospitalised for cardiac and pulmonary ailments found that smokers who used hypnosis to quit smoking doubled their chances of success. In 2019, a Cochrane review was unable to find evidence of benefit of hypnosis in smoking cessation, and suggested if there is, it is small at best.

Hypnosis may be useful as an adjunct therapy for weight loss. A 1996 meta-analysis studying hypnosis combined with cognitive behavioural therapy found that people using both treatments lost more weight than people using cognitive behavioural therapy alone. The virtual gastric band procedure mixes hypnosis with hypnopedia. The hypnosis instructs the stomach that it is smaller than it really is, and hypnopedia reinforces alimentary habits. A 2016 pilot study found that there was no significant difference in effectiveness between VGB hypnotherapy and relaxation hypnotherapy.

American psychiatric nurses, in most medical facilities, are allowed to administer hypnosis to patients in order to relieve symptoms such as anxiety, arousal, negative behaviours, uncontrollable behaviour, and to improve self-esteem and confidence. This is permitted only when they have been completely trained about their clinical side effects and while under supervision when administering it.
