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 ...
[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 Clinically, it is important to distinguish between fever and hyperthermia as hyperthermia may quickly lead to death and does not respond to antipyretic medications.
Febrile seizures happen between the ages of 6 months and 5 years. [1] [3] [29] The peak age for a febrile seizure is 18 months, with the most common age range being 12–30 months of age. [30] They affect between 2-5% of children. [1] [3] [29] They are more common in boys than girls.
Essentially, dehydration may lead to hyperthermia because overheating can alter your body’s normal temperature. (See more about your body's response to heat and what happens when you sweat here ...
c) Remittent fever d) Intermittent fever e) Undulant fever f) Relapsing fever. Intermittent fever is a type or pattern of fever in which there is an interval where temperature is elevated for several hours followed by an interval when temperature drops back to normal. [1] This type of fever usually occurs during the course of an infectious ...
Fever of unknown origin (FUO) refers to a condition in which the patient has an elevated temperature for which no cause can be found despite investigations by one or more qualified physicians. [ 1 ] [ 2 ] [ 3 ] If the cause is found, it is usually a diagnosis of exclusion , eliminating all possibilities until only the correct explanation remains.
With fever, the body's core temperature rises to a higher temperature through the action of the part of the brain that controls the body temperature; with hyperthermia, the body temperature is raised without the influence of the heat control centers.
Sufficient stress from extreme external temperature may cause injury or death if it exceeds the ability of the body to thermoregulate. Hypothermia can set in when the core temperature drops to 35 °C (95 °F). [2] Hyperthermia can set in when the core body temperature rises above 37.5–38.3 °C (99.5–100.9 °F).
