High fever after a hysterectomy may be the result of a traumatic infection, urinary tract infection, or other conditions. Hysterectomy is an invasive procedure that can cause irritation to the body, and after the surgery, the immune system will be relatively low and vulnerable to pathogens. If the wound is not properly protected, it may lead to wound infection triggering high fever. In addition, a urinary catheter needs to be left in place after surgery, which may lead to an infection in the urinary system, thus causing high fever. If high fever occurs after hysterectomy, it is recommended to consult the doctor in time, and early and standardized treatment to reduce the inflammatory reaction, promote the relief of high fever as soon as possible, and promote wound healing.
