Whether or not inflammation in pregnant women has an effect on the baby is related to the part of the body in which the patient is severely affected and the severity of the inflammation. If the inflammation is outside the reproductive tract, and the infection is localized without the clinical symptoms of systemic infection and fever, it has no effect on the baby. However, due to the low resistance of women’s bodies during pregnancy, localized infections must be treated in a timely manner, and it is best to choose local antibiotic treatment. If left untreated, a systemic infection may affect the development of the embryo. If a woman’s inflammation during pregnancy occurs in the reproductive tract, it may affect the baby. Inflammation of the vagina and cervix does not usually affect the baby if it is treated promptly and does not cause an infection. If it is not treated promptly and causes an infection in the uterine cavity, it may cause a miscarriage. Infections in the uterine cavity can have a very serious effect on the baby, and there is a very high risk of stillbirth, cessation of embryonic development, or preterm expulsion of the membranes.
