What causes vaginal bleeding in baby girls?

Generally, female friends will experience vaginal bleeding when they reach puberty, which is called menstruation. This is a normal physiological reaction of women. However, some newborn girls experience vaginal bleeding soon after birth. This phenomenon will inevitably make some new mothers very worried. So, what is the reason for vaginal bleeding in baby girls? Many parents want to understand this issue clearly. Let us ask an expert to introduce it to everyone in detail.

Some baby girls will experience vaginal bleeding 5-7 days after birth. The amount of bleeding is very small, and generally a small amount of bloody secretions can be seen. It often lasts for 1-2 days. In some newborn girls, it may last as long as 3-5 days and then disappear naturally. This phenomenon of vaginal bleeding in newborn girls is somewhat similar to menstrual bleeding, so it is called "false menstruation." It is one of the special physiological phenomena of newborn girls and is not pathological. So, what is the cause of vaginal bleeding in baby girls?

Experts point out that the reason for this phenomenon is that newborn girls have a certain amount of estrogen in their bodies before birth. Most of this estrogen is passed to the fetus through the placenta from the mother, and the other part is secreted by the fetus itself. While the fetus is in the uterus, the cells in the reproductive tract proliferate and become congested due to the influence of estrogen. After birth, most of the sources of estrogen in the newborn girl's body are suddenly cut off, and the estrogen level drops sharply. By 5-7 days after birth, it has dropped to an extremely low level, causing the originally proliferating and congested cells in the reproductive tract to fall off, resulting in vaginal bleeding.

When parents understand that vaginal bleeding in newborn girls is a temporary physiological phenomenon, they will not panic when encountering this situation. Parents should pay attention to the amount of bleeding. If the vaginal bleeding is not much, special treatment is generally not required. Just strengthen care, change diapers frequently, and clean the vulva with a clean towel and small basin after urination and defecation. At this time, please note that it is not advisable to bathe the newborn girl in a bathtub to ensure local cleanliness and prevent infection.

After reading the above experts' detailed answers to the question of why baby girls have vaginal bleeding, I believe everyone should now understand that vaginal bleeding in baby girls is actually a special physiological phenomenon of newborn girls and is not a pathological condition. It is only a short-term physiological phenomenon. Parents do not need to worry too much. If the amount of bleeding is heavy, they should go to the hospital for examination and treatment in time.
