Modulation of orocaecal transit time by hypnosis

Article Abstract:

Gastrointestinal motility (contraction of the bowel), and consequently the speed with which gastrointestinal contents move through the intestines, can be influenced by psychological factors. For example, it has been shown that psychological stress can shorten orocecal transit time (i.e. increase the speed with which food moves from the mouth to the cecum). Hypnosis induces a physiological state opposite to that induced by stress (e.g. blood pressure, heart rate, and respiratory rate all decrease during hypnosis and increase during stress); the effect of hypnosis in and of itself on orocecal transit is not known, although it would be expected to produce effects opposite to those of stress. To determine the effect of hypnotic suggestion on intestinal transit rate, orocecal transit time was measured in 6 healthy volunteers who had not taken antibiotics recently, and had never taken laxatives. hypnosis, During hypnosis, orocecal transit time was slowed by about 40 percent (average was 93 minutes to 133 minutes). When subjects were instructed during hypnosis to imagine a cascade running fast, as was (according to the hypnotist) the liquid in their intestines, there were no significant differences between the control period and the hypnosis period; however, two subjects who had been previously hypnotized showed dramatic increases in orocecal transit rate.

Sexual and physical abuse is not associated with rectal hypersensitivity in patients with irritable bowel syndrome
