Motion Sickness

Thursday, July 12, 2012

If youve ever been sick to your stomach on a rocking boat or a bumpy airplane ride, you know the discomfort of motion sickness. Dr. Edward Hill explains more about motion sickness in todays 60 Second Housecall.

Dr. Hill:

Motion sickness occurs when the body sensors that detect motion send conflicting messages to the brain. These sensors include the inner ear, the eyes and brain proprioceptors. One part of your balance-sensing system may indicate that your body is moving, while the other parts do not sense motion.

People can become motion sick in cars, airplanes, trains, amusement park rides or on boats or ships. Although there are no long-term problems, motion sickness can make life miserable, especially for people who travel a lot.

Common symptoms of motion sickness are dizziness, nausea, vomiting, headache and sweating.

Its best to try to prevent motion sickness, because symptoms are hard to stop once they start. Once motion sickness has developed, relief comes only after the motion has stopped.

Several medications may prevent motion sickness and may also help reduce symptoms once they have begun. These include scopolamine patches, Dramamine and Antivert. Some advocate acupressure bracelets that apply pressure to specific areas in the wrist.
