Heavy periods can significantly affect a woman’s daily life, particularly when they are accompanied by blood clots, menstrual pain or periods occurring every 15–20 days. For some women, especially those who want to avoid more invasive treatment, an LNG-IUD may be considered as a treatment option after proper gynecological evaluation.
In this article, Dr. Archana Belvi, Senior Consultant in Obstetrics and Gynecology at Momstory, Hadapsar, explains what an LNG-IUD is, how it helps manage heavy menstrual bleeding, and what women can expect from the procedure.
What Is an LNG-IUD?
LNG-IUD stands for Levonorgestrel-Releasing Intrauterine Device. One commonly known brand is Mirena.
It is a small, T-shaped device similar in appearance to a Copper-T that is placed inside the uterus by a gynecologist.
Unlike a Copper-T, the LNG-IUD continuously releases a small amount of levonorgestrel, a progestin hormone, inside the uterus. This helps thin the uterine lining and can significantly reduce menstrual bleeding over time.
When May an LNG-IUD Be Recommended?
An LNG-IUD may be considered for women experiencing menstrual problems such as:
- Heavy menstrual bleeding
- Passing large or frequent blood clots during periods
- Painful periods
- Frequent periods
- Abnormal bleeding during the perimenopausal years
However, not every case of heavy bleeding should be treated in the same way. The underlying cause of abnormal bleeding needs to be evaluated by a gynecologist before deciding whether an LNG-IUD is appropriate.
Can an LNG-IUD Help Avoid Uterus Removal?
For younger women with heavy menstrual bleeding, hysterectomy or removal of the uterus may not always be the first treatment option.
Depending on the cause of the bleeding and the woman’s overall health, an LNG-IUD may provide a less invasive alternative for managing symptoms.
The decision between medication, an LNG-IUD, another procedure or surgery should be made after a complete gynecological evaluation.
How Does an LNG-IUD Help With Heavy Periods?
Once placed inside the uterus, the LNG-IUD releases a small amount of hormone locally.
This acts primarily on the uterine lining and can gradually:
- Reduce menstrual blood flow
- Reduce the passage of blood clots
- Improve painful periods or dysmenorrhea
- Make frequent periods less troublesome
- In some women, eventually stop menstrual bleeding altogether
The amount and pattern of bleeding can change gradually after insertion, and individual experiences may vary.
Is It Normal for Periods to Stop After an LNG-IUD?
Yes. In some women, menstrual bleeding becomes progressively lighter and may eventually stop while using an LNG-IUD.
This is called amenorrhea, and it does not necessarily mean that the woman has entered menopause.
The LNG-IUD primarily affects the lining of the uterus. The ovaries can continue to function, and menopause will occur naturally based on ovarian function and age rather than simply because periods have stopped after LNG-IUD insertion.
Does an LNG-IUD Cause Early Menopause?
No. Not having periods while using an LNG-IUD does not mean that the device has caused menopause.
This is an important distinction, particularly for women approaching their perimenopausal years.
Menopause occurs because of natural changes in ovarian function. The reduction or absence of menstrual bleeding with an LNG-IUD occurs because of its effect on the uterine lining.
What Happens Before LNG-IUD Insertion?
Before recommending an LNG-IUD for heavy or abnormal menstrual bleeding, the gynecologist may first evaluate the uterus and determine the possible cause of the bleeding.
In the approach described by Dr. Belvi, hysteroscopy may be performed to examine the inside of the uterus before the LNG-IUD is placed.
The exact preparation and method of insertion can vary depending on the patient’s symptoms, medical history and clinical findings.
Is LNG-IUD Insertion a Day-Care Procedure?
In the procedure described by Dr. Belvi, hysteroscopic evaluation followed by LNG-IUD placement is performed as a day-care procedure under anaesthesia.
The patient can usually:
- Be admitted in the morning
- Undergo the procedure
- Be discharged later the same day if medically stable
- Take approximately two to three days of rest as advised
It is worth noting that LNG-IUD insertion itself does not always require hysteroscopy, general anaesthesia or hospital admission. The approach depends on the individual patient’s clinical situation and the reason for insertion.
Who Should Consider Speaking to a Gynecologist About an LNG-IUD?
Consider consulting a gynecologist if you regularly experience:
- Very heavy periods
- Blood clots during menstruation
- Periods every 15–20 days or unusually frequent bleeding
- Significant pain during periods
- Menstrual bleeding that interferes with everyday activities
These symptoms can have several possible causes, so proper evaluation is important before starting treatment.
What Should You Expect After an LNG-IUD Is Inserted?
Changes in menstrual bleeding are common after LNG-IUD insertion. Some women may experience irregular bleeding or spotting initially, followed by progressively lighter periods over time.
For some women, periods may eventually stop altogether.
Your gynecologist will advise you about follow-up and when to seek medical attention after insertion.
Conclusion
An LNG-IUD can be an effective option for managing heavy menstrual bleeding, painful periods and frequent periods in appropriately selected women. It may help reduce bleeding and, in some cases, provide an alternative to more invasive treatment.
If your periods are unusually heavy, you regularly pass blood clots, experience significant menstrual pain or have periods very frequently, consult a gynecologist to determine the underlying cause and whether an LNG-IUD may be suitable for you.
