( Researchers at the Wake Forest Universi...)Precautious Measure Help Tolerate Nausea In Patients,Health

Researchers at the Wake Forest University School of Medicine and colleagues finds it’s better to inform the patients who undergo difficult medical procedures //about the dizzy feel of nausea previously.

‘A person’s expectations can strongly affect how they respond to adversity – both subjectively and physiologically,’ said lead author Max E. Levine, Ph.D. ‘Being prepared for difficulty can benefit people greatly.’

The study, designed to determine how expectations affect symptoms of nausea and motion sickness, found that participants who were led to expect considerable nausea actually fared better than those who weren’t. The results are reported in the current issue of Psychosomatic Medicine.

Participants were 75 healthy college students who were assigned to one of three groups. All groups were given placebo, or ‘dummy’ pills. One group was led to believe that the pill would protect them against the development of nausea and motion sickness. A second group was told that the pills would make their nausea worse. And, a third group was told that the pills were placebos and would have no effect whatsoever.

Participants sat on a stool inside a drum marked with vertical stripes – viewing the drum’s rotation induced the illusion of self-motion. The drum was rotated at a constant speed for 16 minutes, unless participants asked that it be stopped early.

While the drum was rotating, an intercom system was used to ask participants about symptoms of nausea and motion sickness, including warmth, dizziness and drowsiness. Based on the reported severity of symptoms, a score was calculated for each participant. In addition, three electrodes placed on the surface of their abdomens detected the presence of any of the abnormal stomach activity that typically accompanies nausea.

The nausea scores of the ‘placebo-control group,’ those participants who were told the pills would have no effect, were about 2.5 times higher than t
