Uterine Fibroids

Uterine fibroids are common non-cancerous growths in the uterus. They typically develop during the years a woman is likely to become pregnant. These growths, also known as leiomyomas or myomas, are not linked to an increased risk of other cancers in the uterus.

Fibroids can vary significantly in size and number. Someone might have just one fibroid, or several. Some are so small they're undetectable without medical equipment. Others can grow quite large, sometimes reaching the size of a grapefruit or even larger. A very large fibroid can change the shape of the uterus, both inside and out. In rare cases, a fibroid can grow so large it fills the pelvic or abdominal area, potentially causing a woman to appear pregnant.

Many women will develop uterine fibroids at some point. Often, fibroids don't cause any noticeable symptoms. A doctor might only discover them during a routine pelvic exam or an ultrasound, especially during pregnancy.

Many people with uterine fibroids don't experience any noticeable problems. However, when symptoms do appear, they can vary depending on where the fibroids are located, how big they are, and how many there are. Common symptoms include:

• Heavy or painful periods: This could mean heavier bleeding than usual, longer periods, or periods that are more frequent than normal. The pain might be severe enough to interfere with daily activities.
• Pelvic pressure or pain: Feeling pressure or discomfort in the lower abdomen or pelvis.
• Frequent urination or problems urinating: This can happen because the fibroids are pressing on the bladder.
• Swelling in the abdomen: In some cases, fibroids can cause a noticeable swelling or enlargement in the lower abdomen.
• Constipation: The fibroids can sometimes put pressure on the intestines, making it harder to have bowel movements.
• Pain in the abdomen, lower back, or during sex: This pain can range in intensity.
• Sudden, severe pain: In rare cases, a fibroid can die or lose its blood supply, causing a sudden and intense pain in the lower abdomen. This is a medical emergency.

Fibroids are often categorized by their location within the uterus:

• Intramural fibroids: Grow within the muscle wall of the uterus.
• Submucosal fibroids: Grow into the uterine cavity (the space inside the uterus).
• Subserosal fibroids: Grow on the outside of the uterus.

It's important to see a doctor if you experience any of the following:

• Persistent pelvic pain: Pain that doesn't go away.
• Heavy or painful periods that interfere with your daily life: If your periods are significantly affecting your ability to do normal activities.
• Spotting or bleeding between periods: This could be a sign of a problem.
• Problems emptying your bladder: Difficulty urinating.
• Ongoing tiredness and weakness: These could be signs of anemia (low red blood cell count).
• Severe vaginal bleeding: Heavy or rapid bleeding from the vagina.
• Sudden, sharp pelvic pain: This is a serious situation and requires immediate medical attention.

If you have any concerns about uterine fibroids, it's crucial to talk to your doctor. They can diagnose the problem and recommend the best course of action.

See a doctor if you have persistent pelvic pain. This means pain in your lower abdomen and pelvis that doesn't go away. Also, see a doctor if you're having periods that are unusually heavy or painful, making it hard to do everyday activities. If you're spotting or bleeding between your periods, that's another reason to schedule an appointment. If you're having trouble emptying your bladder, that's a sign you should see a doctor. Feeling constantly tired and weak could be a sign of anemia, which means your body doesn't have enough red blood cells.

Seek immediate medical attention if you have heavy vaginal bleeding or sudden, sharp pelvic pain. These are serious symptoms that need to be checked out right away.

Understanding Uterine Fibroids: What Causes Them?

Doctors don't fully understand why uterine fibroids develop, but several factors seem to play a role.

1. Gene Changes: Fibroids often have different genes than the normal muscle cells in the uterus. Think of it like a recipe that's slightly off, leading to the abnormal growth.

2. Hormones: The hormones estrogen and progesterone are essential for the lining of the uterus. They prepare the lining for a potential pregnancy by thickening it each month. But these hormones also seem to encourage fibroid growth. Fibroids have more receptors for estrogen and progesterone than normal uterine muscle cells, making them more responsive to these hormones. After menopause, when hormone levels drop, fibroids often shrink.

3. Other Growth Factors: The body uses various substances to maintain its tissues. One such substance is insulin-like growth factor. Research suggests that these growth factors might also influence fibroid development.

How Fibroids Develop:

Doctors believe fibroids may start from a special cell called a stem cell, located within the muscle of the uterus. This stem cell divides repeatedly, forming a solid, rubbery mass that stands out from the surrounding tissue.

Growth Patterns:

Fibroids can grow at different rates. Some grow slowly, some quickly, and some stay the same size. There might be periods of rapid growth, followed by periods of no growth or even shrinkage.

Pregnancy and Fibroids:

Fibroids that develop during pregnancy sometimes shrink or disappear entirely after childbirth, as the uterus returns to its normal size.

Uterine fibroids are growths in the uterus that can affect women of reproductive age. While the exact cause isn't fully understood, several factors can increase a person's risk.

Race: Women of all races can develop uterine fibroids, but Black women are more likely to experience them, often at younger ages, and sometimes with larger fibroids and more severe symptoms. This difference in risk isn't fully explained, but it's an important factor to consider.

Family history: If your mother or sister had fibroids, you have a higher chance of developing them yourself. This suggests a possible genetic component.

Lifestyle factors: A number of lifestyle choices may also contribute to a higher risk:

• Early Menstruation: Starting your period before age 10 might increase your risk. This is likely because the body is exposed to hormones earlier than usual, which can impact the uterus's development.
• Obesity: Being overweight or obese can increase your chances of developing fibroids. This is often linked to hormonal imbalances.
• Vitamin D deficiency: Having low levels of vitamin D in your body might also be a risk factor. Vitamin D plays a role in many bodily functions, and low levels may affect hormone regulation.
• Diet: A diet high in red meat and low in fruits, vegetables, and dairy products could increase risk. A healthy diet rich in fruits, vegetables, and dairy, often with lean protein, is generally recommended for overall health.
• Alcohol consumption: Drinking alcohol, including beer, may raise the risk of fibroids. This is likely due to the impact of alcohol on the body's overall health and hormone levels.

It's important to remember that these are risk factors, not guarantees. Many women with these risk factors never develop fibroids, and many women without these risk factors do. If you have concerns about fibroids, it's best to discuss them with your doctor.

Uterine fibroids are growths in the uterus. Most of the time, they aren't harmful. However, they can sometimes cause problems.

Fibroids can be painful. They can also lead to a decrease in red blood cells, which is called anemia. This happens because heavy bleeding can occur. Feeling tired and weak are common symptoms of anemia. If you have heavy periods, your doctor might recommend iron supplements to prevent or treat anemia. In severe cases, a blood transfusion might be necessary.

Many women with fibroids can still get pregnant. But some types of fibroids, especially those growing inside the uterine lining, can sometimes make it harder to get pregnant or cause problems during pregnancy.

Fibroids might increase the risk of certain pregnancy difficulties. These include:

• Placental abruption: This is when the placenta, the organ that provides oxygen and nutrients to the baby, detaches from the uterus.
• Fetal growth restriction: This happens when a baby isn't growing as expected during pregnancy.
• Preterm delivery: This means a baby is born too early, before 37 weeks of pregnancy.

In short, while most fibroids aren't dangerous, they can cause problems, especially during pregnancy. If you have fibroids and are thinking about getting pregnant, or are already pregnant, talk to your doctor. They can discuss the potential risks and recommend the best course of action.

Scientists are still learning about why fibroids grow in the uterus. More studies are needed to figure out ways to stop them from forming. While preventing fibroids completely might not be possible, many people don't need treatment.

However, you might be able to reduce your chances of getting fibroids by making healthy lifestyle choices. Maintaining a healthy weight is important. Regular exercise is beneficial. And eating a balanced diet, including plenty of fruits and vegetables, is crucial for overall health and could potentially lower your risk.

Some studies suggest that birth control pills or long-lasting hormone-based birth control methods might decrease the risk of fibroids. But, using birth control pills before the age of 16 might be associated with a higher risk of developing them. It's important to talk to your doctor about the best options for you.

Understanding Uterine Fibroids and Their Diagnosis

Uterine fibroids are noncancerous growths that can develop in the uterus. Sometimes, they're discovered during a routine checkup called a pelvic exam. During this exam, a doctor gently inserts a gloved finger or two into the vagina while pressing on your abdomen. This allows them to feel the uterus, ovaries, and other organs. If the doctor feels any unusual lumps or changes in the shape of the uterus, it could suggest fibroids.

If you have symptoms of fibroids, like heavy or irregular bleeding, your doctor might order some tests to confirm the presence of fibroids and determine their size and location. These tests help to plan the best treatment options.

Common Diagnostic Tests:

• Ultrasound: This painless test uses sound waves to create images of the uterus. There are two types:

  • Transabdominal ultrasound: The device is placed on your abdomen.
  • Transvaginal ultrasound: The device is inserted into the vagina for a closer view of the uterus. Ultrasound helps to confirm the presence of fibroids, determine their size and location, and even show if they are impacting other organs.

• Blood tests: If you're experiencing irregular bleeding, blood tests can help pinpoint the cause. A complete blood count (CBC) checks for anemia (low red blood cell count) that can be caused by ongoing blood loss. Other blood tests can look for bleeding disorders or thyroid problems.

• Hysterosonography (Saline Infusion Sonogram): A thin tube (catheter) is inserted into the uterus, and sterile salt water (saline) is injected. This expands the uterine cavity, allowing for a clearer ultrasound image of the uterine lining and any submucosal fibroids (fibroids growing beneath the lining). This is particularly useful if you're trying to get pregnant or have heavy periods.

• Hysterosalpingography: A dye is injected into the uterus and fallopian tubes. X-rays then show the shape of these structures. This test is especially helpful for assessing infertility concerns by checking for blocked fallopian tubes, and can sometimes show submucosal fibroids.

• Hysteroscopy: A thin, lighted instrument (hysteroscope) is inserted through the cervix into the uterus. Sometimes, sterile salt water (saline) is injected to expand the uterine cavity, allowing the doctor to visually examine the uterine walls and fallopian tubes.

• MRI (Magnetic Resonance Imaging): MRI provides detailed images of the uterus and surrounding tissues, helping to pinpoint the location and size of fibroids. It's often used when fibroids are large, or if a person is nearing menopause.

These tests work together to give a comprehensive picture of your condition. Your doctor will recommend the most appropriate tests based on your specific symptoms and medical history. If you have concerns about uterine fibroids, talk to your doctor. They can help determine the best course of action.

Uterine Fibroids: Understanding Treatment Options

Uterine fibroids are non-cancerous growths in the uterus. Many people don't experience any symptoms, and for those with mild symptoms, watchful waiting might be the best approach. If symptoms are bothersome, there are several treatment options available. Fibroids often grow slowly or not at all, and they sometimes shrink after menopause due to changes in hormone levels. Importantly, fibroids rarely affect pregnancy.

Different Treatment Approaches:

There's no single best treatment for uterine fibroids. Your healthcare team will help you decide which option is right for you based on your individual situation and symptoms.

• Medication:

  • Hormone Therapy (GnRH Agonists): These medications temporarily stop your body from producing the hormones estrogen and progesterone, which can shrink fibroids. This is similar to a temporary menopause. Common side effects include hot flashes. Treatment is often limited to six months, as symptoms return when you stop taking the medication. Long-term use can lead to bone loss. Sometimes, these medications are used with low-dose estrogen or progestin (called "add-back therapy") to reduce side effects and extend treatment duration up to 12 months. Doctors may prescribe these hormones to reduce fibroid size before surgery or to ease the transition into menopause. Examples include leuprolide, goserelin, and triptorelin.

  • GnRH Antagonists: These medications can help control heavy bleeding in women who haven't reached menopause. They don't shrink the fibroids themselves, but can be used for up to two years. Using them with add-back therapy can help manage side effects. Examples include elagolix and relugolix.

  • Progestin-Releasing IUD: This device can help reduce heavy bleeding caused by fibroids, but doesn't shrink or remove the fibroids themselves. It also prevents pregnancy.

  • Tranexamic Acid: This non-hormonal medication can help reduce heavy menstrual bleeding. It's taken only during heavy bleeding periods.

  • Other Medications: Your doctor might suggest other medications, such as low-dose birth control pills (which don't reduce fibroid size) or nonsteroidal anti-inflammatory drugs (NSAIDs like ibuprofen or naproxen) to manage pain. If you experience heavy bleeding and anemia, your doctor may recommend iron supplements or vitamins.

• Minimally Invasive Procedures:

  • MRI-Guided Focused Ultrasound Surgery (FUS): This non-surgical procedure uses high-energy sound waves to heat and destroy fibroid tissue. It's done while you're in an MRI machine, allowing your doctor to precisely target the fibroids. This approach preserves the uterus and is an outpatient procedure.

  • Uterine Artery Embolization: This procedure blocks blood flow to the fibroids, causing them to shrink and die. Small particles are injected into the uterine artery.

  • Radiofrequency Ablation (Laparoscopic, Transvaginal, or Transcervical): Heat from radiofrequency energy destroys fibroid tissue, shrinking them. This can be performed through small incisions in the abdomen (laparoscopy), the vagina (transvaginal), or the cervix (transcervical). These methods generally have shorter recovery times than traditional open surgery.

  • Laparoscopic or Robotic Myomectomy: This procedure involves removing fibroids while leaving the uterus intact. Small incisions are used, and robotic systems can offer a magnified 3D view for improved precision. Large fibroids may be broken into smaller pieces (morcellation) during the procedure. In the U.S., the FDA advises against morcellation in most cases to reduce the risk of spreading undetected cancer.

  • Hysteroscopic Myomectomy: This procedure removes fibroids located inside the uterus.

  • Endometrial Ablation: This procedure destroys the uterine lining, reducing heavy bleeding. This often results in the inability to conceive in the future.

• Traditional Open Surgery:

  • Abdominal Myomectomy: This involves a larger incision to remove fibroids. It's often recommended for multiple, large, or deep fibroids.

  • Hysterectomy: This is the most permanent solution; it removes the entire uterus. This procedure is considered the only definitive cure for uterine fibroids. If your ovaries are removed, menopause will begin; you can decide to use hormone replacement therapy to manage menopause symptoms.

Important Considerations:

• Recurrence: Even if you have treatment that doesn't involve removing your uterus, there's a possibility of new fibroids growing in the future.

• Fertility: Some treatments may impact your ability to get pregnant. Discuss options with your doctor if you're trying to conceive or want to preserve fertility.

• Risks and Benefits: Each treatment has potential risks and benefits. Thoroughly discuss all options with your doctor to determine the best approach for your specific situation.

• Complementary Therapies: Some studies suggest acupuncture may be helpful in combination with other treatments.
