Acute mountain sickness without headache at low altitude
A 45-year-old tourist developed AMS three hours after starting to ski in a glacier skiing-region in Austria. His history was noteworthy for chronic stress, coffee-overuse, chronic sleep-deprivation, and previous AMS, 14 years ago at ∼3000 m and six years ago at ∼5100 m. He occasionally trekked to altitudes of 1500–2500 m without problems. The night before suffering AMS he had slept for four hou...
متن کاملIntermittent altitude exposures reduce acute mountain sickness at 4300 m.
Acute mountain sickness (AMS) commonly occurs at altitudes exceeding 2000-2500 m and usually resolves after acclimatization induced by a few days of chronic residence at the same altitude. Increased ventilation and diuresis may contribute to the reduction in AMS with altitude acclimatization. The aim of the present study was to examine the effects of intermittent altitude exposures (IAE), in co...
متن کاملExercise exacerbates acute mountain sickness at simulated high altitude.
We hypothesized that exercise would cause greater severity and incidence of acute mountain sickness (AMS) in the early hours of exposure to altitude. After passive ascent to simulated high altitude in a decompression chamber [barometric pressure = 429 Torr, approximately 4,800 m (J. B. West, J. Appl. Physiol. 81: 1850-1854, 1996)], seven men exercised (Ex) at 50% of their altitude-specific maxi...
متن کاملHigh-altitude headache and acute mountain sickness.
INTRODUCTION Headache is the most common complication associated with exposure to high altitude, and can appear as an isolated high-altitude headache (HAH) or in conjunction with acute mountain sickness (AMS). The purpose of this article is to review several aspects related to diagnosis and treatment of HAH. DEVELOPMENT HAH occurs in 80% of all individuals at altitudes higher than 3000 meters...
متن کاملcharacteristics of headache at altitude among trekkers; a comparison between acute mountain sickness and non-acute mountain sickness headache
purpose headache at altitudes has had an incidence of 25-62% through many related studies. many reasons are identified concerning headache at altitudes such as acute mountain sickness (ams), sinus headache, migraine, tension type headache, and frontal tension headache. this study tried to compare different types of headache among trekkers on mount damavand, a 5671m mountain, iran, to find their...
