Hyperthermia is generally diagnosed by the combination of unexpectedly high body temperature and a history that supports hyperthermia instead of a fever. [2] Most commonly this means that the elevated temperature has occurred in a hot, humid environment (heat stroke) or in someone taking a drug for which hyperthermia is a known side effect ...
Drug-induced hyperthermia, as the sole symptom of an adverse drug reaction, should always be considered. Disseminated granulomatoses such as tuberculosis, histoplasmosis, coccidioidomycosis, blastomycosis and sarcoidosis are associated with FUO. Lymphomas are the most common cause of FUO in adults.
Heat stroke is a clinical diagnosis, based on signs and symptoms. It is diagnosed based on an elevated core body temperature (usually above 40 degrees Celsius), a history of heat exposure or physical exertion, and neurologic dysfunction. [5]
Hyperthermia is an elevation of body temperature over the temperature set point, due to either too much heat production or not enough heat loss. [1] [7] Hyperthermia is thus not considered fever. [7]: 103 [40] Hyperthermia should not be confused with hyperpyrexia (which is a very high fever). [7]: 102
In a medical setting, mild hyperthermia is commonly called heat exhaustion or heat prostration; severe hyperthermia is called heat stroke. Heatstroke may come on suddenly, but it usually follows the untreated milder stages. Treatment involves cooling and rehydrating the body; fever-reducing drugs are useless for this condition.
The diagnosis is suggested on patients with a history of drug exposure to the most common inducing agents such as strong antidopaminergic medications. [ 6 ] [ 40 ] The differential diagnosis includes serotonin syndrome , [ 41 ] encephalitis , toxic encephalopathy , status epilepticus , heat stroke , catatonia and malignant hyperthermia .
Malignant hyperthermia is diagnosed on clinical grounds, but various laboratory investigations may prove confirmatory. These include a raised creatine kinase level, elevated potassium, increased phosphate (leading to decreased calcium) and—if determined—raised myoglobin; this is the result of damage to muscle cells.
Heat intolerance is a symptom characterized by feeling overheated in warm environments or when the surrounding environment's temperature rises. [1] Typically, the person feels uncomfortably hot and sweats excessively.
