Heat-related illness can occur when a person is exposed to high temperatures and humidity, prolonged exposure to the sun, or physical exertion in hot weather.
Signs and symptoms of heat-related illness include fatigue, dizziness, headache, nausea, thirst, muscle cramps, and confusion. Diagnosis is based on physical examination and laboratory tests such as electrolytes, blood tests, and urinalysis.
Heat-related illness should be differentiated from other conditions such as dehydration, heat exhaustion, heat stroke, and heat cramps.
Treatment depends on the severity of the illness and may include rest, fluids, medications, and cooling measures.
The prognosis for heat-related illness is generally good with treatment. However, it is important to take measures to prevent heat-related illness in order to reduce the risk of serious complications or death.
