Aerophagia, dizziness, headache, general discomfort, and fatigue may also occur. Once nausea and vomiting develop, the patient is weak and unable to concentrate. With prolonged exposure to motion, the patient may adapt and gradually return to well-being. However, symptoms may recur if motion increases or recurs after a short respite. Prolonged motion sickness with vomiting may lead to arterial hypotension, dehydration, inanition, and depression.
Motion sickness can be a serious complication in patients with other illnesses.
Prophylaxis and Treatment Prevention is easier than treatment. A supine or semirecumbent position with the head supported is best. Reading should be avoided. Avoiding visual fixation on waves or other moving objects is helpful to some. On a ship, a well-ventilated cabin is important, and going out on deck for a breath of fresh air helps.
