Medical Uses of Hypnosis


Hypnosis, Greek for “sleep,” is a fascinating phenomena.

While hypnotized, people can be given suggestions that effect their subconscious more directly than normal.  They can recover lost memories, or be given suggestions that help them deal with problems like smoking or overeating.

If you tell someone who’s hypnotized that their skin is itching, they may develop a real rash.

Hypnosis has very real physical effects and plays an important role in various medical interventions.  If you doubt the power of the mind over our bodies, remember that someone can develop a big stomach, nausea and all the symptoms of pregnancy – just by believing that they’re pregnant!

A government task force in health said recently that there is “strong evidence” that hypnosis is an effective treatment for chronic pain.  It can help with other conditions too.

Hypnosis and Smoking

Wouldn’t it be amazing if a few sessions and suddenly you couldn’t stand the thought of smoking anymore?

Unfortunately, the data isn’t so optimistic.  Smokers who underwent one session focused on developing mental strategies to create negative associations did show somewhat increased rates of cessation and reduction.  But limited clinical information is an important limiting factor.

That said, hypnosis tends to show a 25% cessation rate in studies, considerably better than placebo.

Hypnosis and Irritable Bowl Syndrome (IBS)

Hypnosis may help with IBS where traditional treatments fail.  One study of 30 patients resistant to traditional treatments had some undergo pyschotherapy and others partake in hypnosis sessions.  The hypnosis group ended up having significant reduction in symptoms that lasted for more than 18 months.

The mechanisms of how hypnosis helps IBS are not clear, but probably has to do with how stress and psychosocial factors effect acid release in the digestive system.  Hypnotizing people and asking them to visualize eating a meal signals acid production as if they really had eaten.

Hypnosis and Pain

Aging is associated with increased pain.  Up to 80% of older residents in a nursing home, for instance, report problems with pain.  Additionally, even younger people suffer from pain associated with injuries or cancer.

Hypnosis is exceptionally useful in pain treatment, helping roughly 75% of those who use it.  It is more effective than biofeedback, cognitive behavioral therapy and possibly even morphine!

Research has shown that hypnosis can help with pain from burns, cancer and fibromyalgia, including other conditions.


Hypnosis, unlike standard medical treatments, is not tightly regulated.  While it is a valid and important tool in treatment, beware hyperbole and claims that are unrealistic.  If you consider hypnosis, make sure your therapist is reputable.

  1. I think probably hypnosis might work as a placebo:
    A placebo (Latin for “I shall please”) is a pharmacologically inert substance (such as saline solution or a starch tablet) that produces an effect similar to what would be expected of a pharmacologically active substance (such as an antibiotic). By extension, “fake” surgery and “fake” therapies are considered placebos.
    Or it might work because it is a palcebo

  2. A good point, Mariana.

    There are ways to control for placebo effect for hypnosis. I think one of my future posts will be on that subject.


  3. Hello, I’ve just now stumbled upon your blog whilst I’m searching around Google as I am searching for some info on hypnotherapy and NLP. I think it’s a good website so I bookmarked you and intend to come back another day to have a more indepth read when I have more time.

  4. Learn about hypnosis fully before you say things about it in the negative.
    I have been a hypnotherapist for 32 years. Hypnosis is the most versatile,effective, non invasive therapeutic modality we have. It is a “God” given tool. All people can use it and learn how to do it. All people need it and don’t know it. Used minimally it is relaxing, helps boost the immune system. Broken bones will heal a week and a half faster than normal. Placebo Ha.
