It is possible to have a fever (i.e., a fever) with cirrhosis, and it is considered that it may be related to decreased liver function, secondary infections, and other causes. If patients with cirrhosis develop fever, they need to seek early medical treatment to find out the cause of the fever. 1. Decreased liver function: When liver function decreases, the inactivation of fever-causing factors decreases, which may cause long-term unexplained low-grade fever, which can be handled by physical cooling, such as wiping the skin with lukewarm water and reducing the amount of clothing. 2. Secondary infection: patients with poor immunity are prone to secondary infections, such as upper respiratory tract infection, pneumonia, peritonitis, etc. Inflammatory factors act on the thermoregulatory center, causing infectious fever, generally high body temperature, accompanied by positive symptoms and signs of the corresponding parts of the body, which need to be treated according to the cause of the disease, and the fever will be relieved after the infected foci are generally controlled. If cirrhosis patients have fever symptoms, they need to seek medical treatment as soon as possible to find out the cause, so as to avoid delaying the condition and causing serious consequences.
