What is the reason for delayed menstruation?

Delayed menstruation after IUD may be related to changes in hormone levels, uterine adaptive response, local inflammation of the endometrium, abnormal position of the IUD, mental stress and other factors. Intrauterine device insertion, or intrauterine device insertion, is one of the common contraceptive methods. Some women may experience changes in their menstrual cycles.

1. Changes in hormone levels

Progesterone-containing IUDs release drugs slowly, inhibiting endometrial hyperplasia, resulting in reduced menstrual flow or longer cycles. This situation usually does not require special treatment and can gradually recover after 3-6 months of adaptation. If abnormalities persist, consider switching to an inert IUD.

2. Uterine adaptive response

As a foreign body, the IUD stimulates uterine contractions and may initially affect the rhythm of endometrial shedding. There is a slight feeling of bloating in the lower abdomen, which usually resolves within 2-3 menstrual cycles after placement. It is recommended to avoid strenuous exercise and apply heat to the abdomen.

3. Local inflammation of the endometrium

Friction of the IUD may cause a slight inflammatory reaction in the endometrium, interfering with normal menstrual cramps. Brown discharge or spotting may occur. The doctor may recommend the use of anti-infective drugs such as metronidazole tablets and levofloxacin tablets.

4. Abnormal position of IUD

Descending or incarcerated IUD may compress the endometrium, causing delayed menstruation and persistent abdominal pain. The position needs to be confirmed through ultrasound examination, and if necessary, remove and reposition or change the contraceptive method.

5. Mental stress

Nervousness about surgery may affect hormone secretion via the hypothalamic-pituitary axis. It is recommended to relieve anxiety through meditation, psychological consultation, etc., and if necessary, use oryzanol tablets for a short period of time to regulate autonomic nerve function.

It is necessary to keep the perineum clean after inserting the ring, and avoid bathing and sexual intercourse for 2 weeks. Check the position of the IUD regularly. If you have severe abdominal pain, fever or abnormal bleeding, you should seek medical attention promptly. You can add iron-rich foods such as animal liver, spinach, etc. to your daily routine to prevent anemia. Moderate exercise can help improve pelvic blood circulation. If menstruation is delayed for more than 3 months or is accompanied by other uncomfortable symptoms, it is recommended to go to the gynecology department for six hormone tests, ultrasound and other examinations to rule out pregnancy and other gynecological diseases.
