How is an intrauterine device (IUD) inserted?

The intrauterine device (IUD) is currently one of the most common contraceptive methods, offering long-term effectiveness, safety, and convenience—making it particularly suitable for women who do not wish to become pregnant. There are many different types and shapes of IUDs available, allowing women to select the most appropriate option based on their individual physical needs. So, how is an IUD inserted? Below is an overview.

How Is an IUD Inserted?

1. First, select the appropriate type—your healthcare provider can help you choose the most suitable option. Hormone-releasing or copper-containing IUDs enhance contraceptive efficacy and are referred to as “medicated” or “active” IUDs; these are currently the most widely recommended types.
2. Once the appropriate IUD has been selected, insertion can proceed. The healthcare provider will first disinfect the area, then use an inserter to place the IUD into the uterus. After successful placement, the inserter is withdrawn, and the nylon thread attached to the IUD is trimmed—completing the procedure.

What Should You Pay Attention To After IUD Insertion?
1. Monitor for vaginal bleeding and IUD expulsion. If vaginal bleeding exceeds twice your normal menstrual flow or persists longer than usual—or if your menstrual cycle changes significantly—you should consult a healthcare provider. During the first three months post-insertion, regularly check whether the IUD has been expelled.
2. Ensure adequate nutrition. After IUD insertion, dietary adjustments are important. Increase your intake of nutrient-rich foods, especially iron-rich options such as lean meat, pork liver, pork kidneys, and eggs. Also include soy products, vegetables, and fresh fruits. Following this dietary regimen helps effectively prevent fatigue and other side effects associated with IUD use.

The above provides an overview of IUD insertion. Generally, IUD insertion is safe; however, rare complications—including vaginal laceration or bleeding—may occur. Although IUDs are designed for long-term use within the body, improper physical activity or posture may cause displacement or expulsion. Therefore, after IUD insertion, women are advised to rest for several days and avoid strenuous exercise.
