Uterine Fibroids: Symptoms, Causes, Treatment

What are the symptoms of uterine fibroids?

Symptoms of uterine fibroids can vary depending on their size, number, and location. Some women may not experience any symptoms, while others may have significant discomfort. Common symptoms include:

• Heavy or Prolonged Menstrual Bleeding: Increased menstrual flow, sometimes leading to anemia.
• Pelvic Pain or Pressure: A feeling of fullness or heaviness in the lower abdomen or pelvis.
• Frequent Urination: Pressure on the bladder can lead to a need to urinate more often.
• Difficulty Emptying the Bladder: A sensation of incomplete bladder emptying.
• Constipation: Pressure on the rectum can lead to bowel issues.
• Backache or Leg Pain: Pain radiating to the lower back or legs.
• Pain During Intercourse: Depending on the location of the fibroids.
• Enlarged Abdomen: Larger fibroids can cause visible abdominal swelling.

In some cases, uterine fibroids can also lead to complications like infertility, miscarriage, or preterm birth.

What are the causes of uterine fibroids?

The exact cause of uterine fibroids is not fully understood, but several factors are thought to contribute to their development. Key causes and risk factors include:

• Hormones: Estrogen and progesterone, hormones that regulate the menstrual cycle, are believed to promote the growth of fibroids. Fibroids often shrink after menopause when hormone levels decrease.
• Genetic Changes: Fibroids often contain genetic alterations that differ from those in normal uterine muscle cells.
• Family History: Having a family member with fibroids increases the likelihood of developing them.
• Race and Ethnicity: African American women are more likely to develop fibroids and at a younger age, and they tend to have more severe symptoms.
• Obesity: Being overweight or obese increases the risk of fibroids.
• Diet: A diet high in red meat and low in green vegetables, fruit, and dairy is associated with a higher risk of fibroids.
• Other Growth Factors: Substances that help the body maintain tissues, such as insulin-like growth factors, may affect fibroid growth.

Although these factors are associated with fibroid development, the exact mechanism behind why fibroids form remains unclear.

What is the treatment for uterine fibroids?

The treatment for uterine fibroids depends on several factors, including the severity of symptoms, the size and location of the fibroids, the patient’s age, and whether they wish to preserve fertility. Treatment options include:

• Watchful Waiting: If fibroids are not causing symptoms, monitoring the fibroids with regular pelvic exams and ultrasounds may be sufficient.
• Medications:
• Hormonal Therapy: Birth control pills, progesterone-releasing IUDs, and other hormone therapies can help control symptoms such as heavy menstrual bleeding and pain.
• Gonadotropin-Releasing Hormone (GnRH) Agonists: These medications shrink fibroids by reducing estrogen and progesterone levels, often used to shrink fibroids before surgery.
• Non-Hormonal Medications: NSAIDs (like ibuprofen) can help manage pain, and tranexamic acid may be prescribed to reduce heavy bleeding.
• Minimally Invasive Procedures:
• Uterine Artery Embolization (UAE): This procedure cuts off the blood supply to the fibroids, causing them to shrink.
• Radiofrequency Ablation: This technique uses radiofrequency energy to shrink fibroids without removing them.
• MRI-Guided Focused Ultrasound Surgery (FUS): A non-invasive procedure that uses high-intensity ultrasound waves to destroy fibroids.
• Surgical Options:
• Myomectomy: Surgical removal of fibroids, preserving the uterus. This can be done through traditional surgery, laparoscopy, or hysteroscopy, depending on the size and location of the fibroids.
• Hysterectomy: Complete removal of the uterus. This is the only permanent solution for fibroids and is usually considered when other treatments have failed or are not suitable.
• Alternative Treatments:
• Endometrial Ablation: This procedure destroys the lining of the uterus to reduce heavy bleeding but is not effective for large fibroids.
• Lifestyle Changes: Maintaining a healthy weight, managing stress, and following a balanced diet may help manage symptoms, though they are not a cure.

Each treatment option has its pros and cons, and the choice of treatment should be made in consultation with a healthcare provider, considering the patient’s individual circumstances and treatment goals.
