Fibroids are common and usually manageable
Uterine fibroids (leiomyomas) are non-cancerous growths of the uterine muscle. They are extremely common: by age 50, more than half of women will have at least one. Many never cause symptoms and are found incidentally.
When they do cause symptoms, fibroids tend to show up as heavier or longer periods, pelvic pressure, and sometimes pain. Most fibroids do not become cancer, and most have multiple treatment options.
What fibroids feel and look like
Fibroid symptoms depend on size, number, and where they sit on the uterus. Some are tiny and silent. Some grow large enough to feel through the lower belly.
Common symptoms:
- Heavier periods or periods that last longer than 7 days.
- Bleeding between periods or after sex.
- Pelvic pressure, fullness, or a sense of weight in the lower belly.
- Frequent urination or difficulty emptying the bladder.
- Constipation or pressure on the bowel.
- Lower-back or pelvic pain, especially in the late luteal phase.
- Pain with sex, often in deeper positions.
Why estrogen matters
Fibroids are hormone-sensitive. They tend to grow during the reproductive years when estrogen is high, often slow down or shrink after menopause, and can grow during pregnancy. This is why hormonal treatments often shrink fibroids or reduce their symptoms.
Genetics, ethnicity (fibroids are more common and often more severe in Black women), and a few lifestyle factors influence risk. Stress and a single life event do not "cause" fibroids.
Treatment options across the spectrum
Treatment depends on symptom severity, size and number of fibroids, fertility plans, and how close to menopause you are. There is no single best answer.
Available paths to discuss:
- Watchful waiting: for asymptomatic or minimally symptomatic fibroids.
- Hormonal treatments: hormonal IUD, combined pills, progestin pills, or GnRH analogs to manage bleeding.
- Tranexamic acid: non-hormonal medication that reduces heavy bleeding.
- Iron support: heavy bleeding often causes iron deficiency, which is treatable.
- Uterine artery embolization (UAE): minimally invasive procedure to shrink fibroids.
- Myomectomy: surgical removal of fibroids while keeping the uterus.
- Hysterectomy: removal of the uterus; definitive but irreversible.
Tracking what your fibroid is actually doing
Fibroids change. A log of bleeding days, flow severity, pain location, and pressure symptoms across a few cycles makes it possible to see whether things are stable, getting worse, or responding to treatment.
Bring that data to appointments. It is more useful than memory, and it lets you and the clinician compare like with like.
When to seek prompt care
Fibroids themselves are rarely emergencies, but a few patterns deserve quick attention: very heavy bleeding that soaks through products every hour for hours, severe sudden pelvic pain, fever, or signs of significant blood loss (lightheadedness, fast heart rate).
Fertility, pregnancy, and fibroids
Most people with fibroids can carry a pregnancy. Some types (especially submucosal fibroids inside the uterine cavity) can affect fertility or increase miscarriage risk and may be removed before trying. A reproductive medicine specialist can help sort out which kind you have and what makes sense.
