When a woman develops a pelvic abscess, if the diameter of the abscess is 4 centimeters, it is a more serious condition, and if it is not treated aggressively, it may cause fever, sepsis, and other adverse consequences. When an abscess occurs in the pelvis, it indicates that there is a more serious infection in the reproductive tract. When the abscess is 4 centimeters, it indicates that there are more bacteria in the body and the white blood cells are more active, so timely treatment must be carried out. At this time, it will be manifested as an increase in body temperature, and if the condition continues to develop, it may lead to bacteria entering the bloodstream, which may result in conditions such as bacteremia and sepsis, posing a threat to life. Therefore, if a woman develops a pelvic abscess, it is recommended that she go to the hospital in a timely manner and under the guidance of the doctor for active treatment.
