Introduction
A displaced Mirena IUD often leads to excessive menstrual bleeding, but this usually does not occur if the device is promptly repositioned. Actual outcomes vary from person to person. Here is a detailed analysis: The Mirena IUD is a levonorgestrel-releasing intrauterine system containing a large amount of progestin. When the Mirena becomes displaced, it may slip into the cervical canal or expel partially or completely through the cervix. In such cases, the drug's effectiveness diminishes, potentially leading to endometrial thickening.
Displacement of the Mirena IUD usually leads to excessive menstruation, but this may not occur if it is adjusted promptly. The actual situation varies from person to person. Detailed analysis is as follows:
1. Yes, it may cause heavy menstruation
The Mirena IUD is a levonorgestrel-releasing intrauterine system containing a large amount of progestin. When the Mirena becomes displaced, it may slip into the cervical canal or even protrude outside the cervix. In such cases, its medicinal effect weakens, potentially leading to endometrial thickening and increased menstrual bleeding. It is recommended to visit a hospital for a follow-up ultrasound to determine the exact position of the Mirena IUD in the uterus.
2. No, it may not cause heavy menstruation
If the displacement of the Mirena IUD is detected early and corrected promptly at a hospital, excessive menstrual bleeding typically does not occur. After proper repositioning, the progestin released into the uterine cavity counteracts estrogen in the body, causing the endometrium to thin and thereby reducing menstrual flow. Prompt adjustment also helps prevent bacterial or other pathogenic infections that could lead to conditions such as endometritis.
In daily life, it's important to take preventive measures against gynecological inflammation, maintain cleanliness and dryness of the genital area, develop the habit of changing underwear frequently, and avoid frequent touching with hands.
