Overview
Physicians and psychiatrists use hypnosis to treat a variety of conditions, including generalized anxiety disorder, phobias (simple, social, performance anxiety), panic disorder, pain, irritable bowel syndrome, and certain dermatological disorders. Therapeutic hypnosis may also be used to aid in smoking cessation or weight loss.
Indications
Cognitive
behavior therapy with exposure to the feared situation is typically the
therapy of choice for phobias. However, hypnosis has been used in the
treatment of various phobias including simple phobia, social phobias,
and performance anxiety. Hypnosis can reduce symptoms of anxiety by
inducing a more tranquil state that is associated with the induction
technique. Additionally, hypnosis has been shown to augment patient’s
resilience when dealing with stressful situations and decreasing
avoidance behavior.
Various
meta-analyses have pointed to hypnosis as an adjunct therapy for
smoking cessation, with reinforcement by regular contact with medical
professionals and counselors as an integral part of the treatment. Although hypnosis is not a definitive treatment, it has been successfully used as an adjunct to treatment. However, in some studies hypnosis was not found to be more effective than cessation trials without hypnosis.
Some
meta-analyses have indicated that hypnosis may enhance weight loss.
Patient undergoing cognitive-behavioral therapy for weight loss were
compared to patients undergoing similar therapy with the addition of
hypnosis, with favorable results reported for 70% of the patients
receiving hypnotic therapy. Mean weight loss was 6.03 lbs for patients
not receiving hypnosis and 14.88 lbs for patients receiving hypnosis.
Further correlational analyses indicated that the benefits of hypnosis
for weight loss increase over time.
According
to one meta-analysis, hypnotic suggestions relieved pain in 75% of 933
subjects participating in 27 different experiments. The pain relief from
hypnosis often matched or even exceeded the relief given by morphine. Another
study showed that participants who were highly suggestible received the
greatest benefit from reduction in pain when compared to placebo. A
participant’s responsiveness to suggestion was the primary determining
factor in the extent of pain reduction.
One
of the most studied uses of hypnosis in medicine is the treatment of
irritable bowel syndrome. Treatment methods typically consist of
medication and dietary changes, but the addition of hypnosis has been
shown to decrease and even eliminate symptoms. Palsson et al. showed
that hypnosis benefited patients suffering from irritable bowel
syndrome for at least 10 months. Initially, imagery directed at reducing
pain was used, but the authors found that hypnosis alone gave patients
the most benefit.
Some studies have shown that hypnosis can be used as an adjunct treatment for various skin conditions, including alopecia areata and psoriasis.
These studies had a limited number of participants but showed that
hypnosis therapy could help alleviate stress in patients suffering from
dermatological conditions. The patients were broken into two groups,
with one group receiving active suggestions and another receiving
hypnosis. Patients who were shown to be highly hypnotizable displayed
greater improvement than moderately hypnotizable patients, regardless of
which modality of treatment was used.
Contraindications
When
evaluating a patient for potential hypnosis, it is important to
consider possible contraindications, including the emotional state of
the patient and the desired outcome. Cooperation is an essential element
for effective hypnosis. If an individual is uncooperative or hostile,
hypnosis may not be the best treatment option. Additionally, some
patients will not be able to hypnotized due to brain trauma or cognitive
deficits. In these cases, hypnosis is contraindicated.
The use of
hypnosis is generally not advisable for patients with borderline
personality disorder, dependent personality disorder, or psychosis. For
patients with borderline personality disorder or dependent personality
disorder, there is a risk that the patient will want to form intense or
inappropriate relationships or interactions with the practitioner.
Perhaps the most important concern is that hypnosis could exacerbate a
pre-existing psychosis. Therefore, hypnosis is contraindicated for a
patient displaying signs of psychosis.
Technical Considerations
An
abreaction is a negative response that can occur at any time during
hypnosis. It is sometimes caused by unpleasant or uncomfortable memories
that are brought into awareness during hypnosis. Some practitioners of
hypnosis use abreactions as part of the therapy; others seek to limit
these experiences. An abreaction is often an uncomfortable situation
that may be followed by crying or angry outbursts. Addressing the
concerns of the participant by acknowledging the abreaction is often the
safest way to deal with the situation.
Many myths are associated
with hypnosis, including that people lose control while in a hypnotic
state and that they can become “stuck” in a trance. Hypnosis is a
voluntary act and patients are always in control of their actions. For
example, if a practitioner suggests something that is not agreeable to a
patient, the patient will not do it. In addition, hypnosis is not a
permanent condition; it usually ends as soon as the practitioner starts
the termination process. However, a patient can end the hypnotic state
at any time he or she chooses.
