Fever in cerebral hemorrhage may be caused by infection, hematoma absorption, and the influence of body temperature center.
1. Infection: when there is an infection foci in the body of patients with cerebral hemorrhage, the pathogens in the infection foci will cause an increase in the production and release of thermogenic factors in the body, resulting in an imbalance between heat production and heat dissipation, which can cause an increase in body temperature, i.e. fever.
2. Hematoma absorption: the hematoma formed at the site of cerebral hemorrhage will be absorbed by the body, resulting in absorption of heat, but generally the degree of increase in body temperature is not high, mostly lower than 38.5 ℃.
3. The thermoregulation center is affected: cerebral hemorrhage affects the thermoregulation center, causing dysfunction of the thermoregulation center and imbalance between heat production and heat dissipation, thus causing fever.
Cerebral hemorrhage fever should go to the hospital in time to improve the examination and give targeted treatment after the cause is clear.
