What causes bleeding three days after menstruation ends following IUD insertion?

Bleeding three days after menstruation has ended following the insertion of an intrauterine device (IUD) may be caused by physiological factors or pathological factors, such as IUD displacement or cervical infection. The specific analysis is as follows:

I. Physiological Factors

If there is an abnormality in estrogen levels within the body, it may lead to excessive thickening of the endometrium, resulting in bleeding three days after menstruation ends following IUD insertion. This is considered a normal physiological phenomenon and can be alleviated by adjusting diet and lifestyle habits.

II. Pathological Factors

1. Intrauterine Device Displacement

Engaging in overly vigorous sexual intercourse or strenuous physical activities shortly after IUD insertion may cause displacement of the device, damaging the mucous membrane of the cervix and leading to the aforementioned symptoms. Patients should promptly visit a qualified medical institution for evaluation and possible removal of the IUD.

2. Cervical Infection

If patients are invaded by pathogens such as aerobic or anaerobic bacteria, cervical infection may occur. Under stimulation by inflammatory factors, the cervical mucosa may produce this symptom. Treatment should follow medical advice, including the use of medications such as cefixime capsules or levofloxacin hydrochloride capsules.

In addition, bleeding three days after menstruation ends following IUD insertion could also result from vaginal infection, endometrial infection, cervical tissue hyperplasia, or other conditions. It is recommended that patients seek timely medical attention when experiencing discomfort.
