Nausea caused by motion / From Wikipedia, the free encyclopedia
Motion sickness occurs due to a difference between actual and expected motion.[1] Symptoms commonly include nausea, vomiting, cold sweat, headache, sleepiness, yawning, loss of appetite, and increased salivation.[1] Complications may rarely include dehydration, electrolyte problems, or a lower esophageal tear.[1]

The cause of motion sickness is either real or perceived motion.[1] This may include from car travel, air travel, sea travel, space travel, or reality simulation.[1] Risk factors include pregnancy, migraines, and Meniere’s disease.[1] The diagnosis is based on symptoms.[1]
Treatment may include behavioral measures or medications.[2] Behavioral measures include keeping the head still and focusing on the horizon.[1] Three types of medications are useful: antimuscarinics such as scopolamine, H1 antihistamines such as dimenhydrinate, and amphetamines such as dexamphetamine.[2] Side effects, however, may limit the use of medications.[2] A number of medications used for nausea such as ondansetron are not effective for motion sickness.[2]
Nearly all people are affected with sufficient motion.[1] Susceptibility, however, is variable.[1] Women are more easily affected than men.[1] Motion sickness has been described since at least the time of Hippocrates.[1] "Nausea" is from the Greek naus meaning ship.[1]
