Patient's question:
What are the conditions required for using an IUD, and when can it be used? Does it have a time limit?Doctor's answer:
Medical Analysis: An intrauterine device (IUD) is a contraceptive device placed inside the uterine cavity. Since the initial devices used were mostly ring-shaped, they are commonly referred to as "uterine rings." IUDs cause minimal interference to the body as they act locally and do not affect fertility after removal. They offer advantages such as safety, effectiveness, reversibility, simplicity, and cost-effectiveness, making them one of the most commonly used contraceptive methods. In China, over 40% of women use IUDs for contraception, with an effectiveness rate of approximately 90%.1. Which situations are not suitable for inserting an IUD?
- Acute pelvic inflammatory disease
- Acute vaginitis
- Severe cervical erosion
- Heavy menstrual bleeding or irregular bleeding
- Uterine fibroids
- Narrow cervical os
Women with severe systemic diseases should also avoid using IUDs, as this can worsen inflammation or increase menstrual bleeding.
2. What should be noted before and after inserting an IUD?
Although inserting an IUD is a simple and safe procedure, it is still a surgical operation. To prevent infection, sexual activity should be avoided for three days before the procedure and for two weeks after. Maintain good vaginal hygiene, and avoid taking baths after insertion to prevent uterine cavity infection. Rest for 1–2 days after the procedure, and avoid heavy physical labor or strenuous exercise for at least one week, as the cervix may be looser after insertion, making the ring more likely to fall out.
3. Pay attention to checking whether the IUD has fallen out.
Women with a loose cervix or heavy menstrual bleeding may experience IUD during their period. Therefore, when using the restroom during their period, they should check if the ring has fallen out with the blood. After insertion, a check-up should be scheduled at the hospital one month after the period ends, followed by another check-up after three months. Subsequently, follow-up checks can be conducted every 1–2 years. During the first three months after insertion, especially during the period, it is particularly important to check if the IUD has fallen out. If it does, other contraceptive measures should be taken immediately, and the IUD should be reinserted after the next period.
Advice: The insertion of an IUD is typically performed 3–7 days after the period ends, when sexual activity has been avoided. As long as there are no contraindications to IUD insertion, it can be done. There is no age limit, as long as the woman has not gone through menopause. Inserting an IUD is a common minor gynecological procedure and is not very painful. However, painless insertion is available, but personally, it is not necessary to choose this option. The procedure for inserting an IUD usually takes only about one minute.
