Introduction
In general, "inserting a ring" refers to the placement of an intrauterine device (IUD). There may be some risks associated with women using intrauterine devices. Placement of an IUD might lead to menstrual irregularities, abdominal pain and backache, increased risk of infection, displacement or expulsion of the device resulting in unintended pregnancy, and effects on sexual life. Before choosing to insert an IUD, one should fully understand her own health condition and the risks associated with the procedure.

Generally speaking, "inserting an IUD" refers to the placement of an intrauterine device (IUD). There may be some risks associated with women using intrauterine devices. The use of an intrauterine device may lead to menstrual irregularities, abdominal pain and backache, increased risk of infection, unintended pregnancy, and impact on sexual life. Detailed analysis is as follows:

1. Menstrual irregularities

An intrauterine device placed in the uterus may stimulate the endometrium, causing local vascular proliferation and congestion, which can lead to heavier menstrual bleeding than before. Some women may also experience prolonged menstruation, as the presence of the device may interfere with the normal shedding and repair process of the endometrium, resulting in prolonged or irregular bleeding. Additionally, menstrual cycles may become disordered, with menstruation occurring earlier than usual, delayed, or accompanied by irregular bleeding.

2. Abdominal pain and backache

The uterus may have a rejection reaction to the intrauterine device, causing uterine contractions. These contractions may lead to lower abdominal pain. At the same time, due to the uterine contractions and irritation of surrounding tissues by the intrauterine device, backache may also occur. Symptoms of backache may worsen after prolonged standing or physical activity.

3. Increased risk of infection

Placement of an intrauterine device is an intrauterine procedure. If strict aseptic techniques are not followed during the procedure, or if the individual has a weak defense mechanism in the reproductive tract, infection may easily occur. Common infections include endometritis and pelvic inflammatory disease.

4. Risk of unintended pregnancy

An intrauterine device may shift out of position in the uterus for various reasons. For example, vigorous physical activity, frequent heavy labor, or changes in the natural position of the uterus may cause displacement of the device. Once displaced, the contraceptive effectiveness of the IUD may be lost, leading to unintended pregnancy. In addition, the intrauterine device may also spontaneously expel, which is more likely to occur during menstruation. If the expulsion of the device goes unnoticed, unintended pregnancy may easily occur.

5. Impact on sexual life

Some women may experience pain during intercourse. This may be due to the IUD's tail string being too long, which may stimulate the male's penis or the female's vaginal vault during sexual activity, thereby causing pain.

Before choosing to have an intrauterine device inserted, it is important to fully understand your own health condition and the risks of the procedure, and to make an informed decision under the guidance of a doctor. After the procedure, attention should also be paid to personal hygiene and rest, and follow-up visits and check-ups should be conducted as instructed by the doctor.
