Uterine Fibroids: Symptoms, Diagnosis & Treatment

Uterine fibroids symptoms diagnosis treatment and warning signs are called fibroid care. Fibroids grow from muscle cells in the uterus.

Many fibroids cause no symptoms. Doctors may find them during an exam or imaging done for another reason.

Other fibroids can affect bleeding, pain, bladder use, bowel habits, or fertility. Their size, number, and location often shape the symptoms.

This guide explains common signs, testing, and fibroid treatment options. It also covers fibroid warning signs that need medical care.

Uterine fibroids are also called leiomyomas or myomas. They are growths that form in or around the muscle of the uterus.

Fibroids are benign, which means they are not cancer. They almost never turn into cancer.

A person may have one fibroid or several. Some are too small to see without imaging.

Others can grow larger than a grapefruit. Very large fibroids may change the shape of the uterus or abdomen.

Fibroid growth patterns can vary over time. They may grow slowly, grow fast, stay stable, or shrink.

By menopause, fibroids affect 50% to 70% of females. Reported rates exceed 80% among Black women.

Doctors group fibroids by where they grow:

Location can affect symptoms and treatment choices. Small submucosal fibroids may still cause heavy bleeding.

Large outer fibroids are more likely to cause pressure. That pressure may affect the bladder or bowel.

The exact cause of uterine fibroids is not known. Several body processes may help them form or grow.

Estrogen and progesterone appear to support fibroid growth. These hormones help control the menstrual cycle and pregnancy.

Gene changes may also play a role. Other growth factors and muscle cells may affect growth.

Fibroids often shrink after menopause as hormone levels fall. However, each person's fibroid growth may follow a different pattern.

Age and family history may affect risk. Risk is higher if a mother or sister had fibroids.

Other possible risk factors include obesity and early periods ^6,8. High blood pressure and some diet factors may also have links.

Black people may develop fibroids at younger ages. They may also have more fibroids and worse symptoms.

Experts do not fully understand these racial gaps. These differences may reflect wider health gaps as well as body factors.

A person can develop fibroids without known risk factors. Risk factors alone cannot confirm that fibroids are present.

Many people with fibroids have no symptoms. About 25% to 30% have symptoms that affect health or daily life.

Common uterine fibroid symptoms involve bleeding, pain, and pressure ^2,10. Some fibroids may also affect fertility or pregnancy.

Abnormal bleeding is a common fibroid symptom ^2,10. The amount, timing, or length of bleeding may change.

Bleeding-related symptoms may include these problems:

A complete blood count can check for anemia. Iron tests can show whether low iron is present.

Fibroids may cause pressure, fullness, or pain in the pelvis. Large fibroids may make the lower abdomen look enlarged.

Possible pain and pressure symptoms include the following:

A fibroid can cause sudden pain after losing its blood supply. Other health problems can also cause sharp pelvic pain.

Large fibroids may press on nearby organs. Front growths often cause bladder symptoms.

Possible bladder or bowel changes include these symptoms:

Urinary symptoms can have several causes. The UTI symptoms guide explains another common source of urinary problems.

Fibroids may be linked with infertility in some people. Their effect often depends on their location ^2,10.

Growths that change the womb cavity may disrupt embryo placement. An embryo is an early stage of pregnancy.

Fibroids are also linked with miscarriage and early labor. Other links include placental problems and cesarean birth.

The placenta gives oxygen and food to the growing baby. Some fibroids may also raise the risk of heavy bleeding after birth.

Future pregnancy goals should shape treatment choices. Some options keep the uterus, while hysterectomy removes it.

Some fibroid warning signs need care right away. Other symptoms call for a prompt medical visit.

Seek emergency care now in either of these situations:

These symptoms should not be assumed to come from fibroids. A medical exam can assess the cause.

Contact a clinician promptly for these symptoms:

Tell your clinician about new or worse symptoms during monitoring. Your clinician may suggest an exam or new imaging.

Bleeding, pain, and bladder problems can have causes besides fibroids. A normal pelvic exam cannot rule out small fibroids.

A postmenopausal state can raise concern during mass evaluation. Cancerous masses and common fibroids are both possible diagnoses for uterine masses ^9,10.

Fibroids are not always found on imaging; some are discovered during a clinical examination ¹⁰. Doctors may change surgical plans when cancer risk is a concern ^7,10.

Avoid diagnosing new symptoms on your own. An exam can help identify the likely cause and guide the next step.

Uterine fibroid diagnosis begins with your health history and an exam. Blood tests and imaging can then help confirm the cause.

A clinician may ask about bleeding, pain, and pelvic pressure. Questions may also cover bladder changes, bowel habits, and fertility concerns.

Describe when symptoms began and how they affect daily life. Also explain your plans for pregnancy and keeping the uterus.

The exam may include checks of the abdomen, vagina, cervix, and pelvis. A pelvic exam may find a large or uneven uterus.

Small fibroids may not change the pelvic exam. Symptoms may still require more testing after a normal exam.

Fibroids are sometimes found during routine exams. Doctors may also find them by chance during imaging.

Tests depend on your symptoms and exam findings. Your clinician may consider the following checks:

Not every person needs each test. The clinician chooses tests based on the likely causes.

Pelvic ultrasound is the preferred first imaging test ^3,7,10. It uses sound waves to create pictures of the uterus.

Doctors often combine two types of ultrasound:

Together, these scans can show each fibroid's size and location. They can also show the number of fibroids.

MRI means magnetic resonance imaging. It can show size and location in more detail.

Doctors may use MRI to plan treatment. It may also help when the uterus is large.

Some people need more tests after an ultrasound. These tests may clarify fibroid location or check other causes.

Options may include the following procedures:

Endometrial means related to the inner lining of the uterus. Doctors may also consider biopsy when abnormal bleeding continues.

Treatment is not needed for every fibroid. Fibroid treatment options depend on symptoms, goals, and test results.

Fibroids without symptoms may only need routine monitoring. Watchful waiting may also suit some mild symptoms.

Monitoring may include health visits and repeat imaging. Tell the clinician if symptoms become new or worse.

Several factors guide treatment choices:

There is no single best choice for every person. Ask about benefits, risks, recovery, and pregnancy plans.

Medicines may control symptoms without removing fibroids. The best option depends on your main symptoms and goals.

Common medicine choices include these options:

GnRH means gonadotropin-releasing hormone. These medicines change hormone signals involved in periods and fibroid growth.

Hormonal birth control may reduce bleeding without shrinking fibroids. A hormone-releasing device prevents pregnancy while in place.

GnRH agonists can stop periods and shrink fibroids for a time. They may also improve anemia before surgery.

These medicines may cause hot flashes. Longer use may also lead to bone loss.

Symptoms often return after GnRH agonists stop. GnRH antagonists can treat heavy bleeding before menopause.

Some procedures treat fibroids without removing the uterus. They may reduce bleeding, pressure, or fibroid size.

Available procedures include these choices:

Focused ultrasound does not require surgical cuts. MRI images help the doctor target the correct tissue.

These methods preserve the uterus. Still, pregnancy goals should be discussed before any procedure.

Myomectomy removes fibroids but keeps the uterus. Future pregnancy remains possible because the uterus stays in place.

Doctors can perform myomectomy through different surgical methods. The choice depends on fibroid size, number, and location.

Hysterectomy removes the whole uterus. It prevents a person from carrying a future pregnancy.

Hysterectomy is the only definitive treatment for fibroids. Doctors can use open, vaginal, or less invasive methods.

Discuss surgery through shared decision-making. Your symptoms, risks, fertility goals, and preferences should guide the choice.

Uterine fibroids are benign, and many cause no symptoms. Others may cause bleeding, anemia, pain, pressure, or fertility concerns.

Diagnosis often begins with an exam and pelvic ultrasound. Treatment may involve monitoring, medicines, procedures, or surgery.

Discuss each option with a qualified clinician. Shared choices can reflect your symptoms, risks, and pregnancy goals.
