Uterine fibroids, also known as leiomyomas, are non-cancerous growths that develop in the uterus. They are a common health concern affecting many women worldwide. While fibroids are generally benign, they can cause a range of symptoms and impact a woman’s quality of life. This article aims to provide an overview of uterine fibroids, including their causes, symptoms, and available treatment options.

Main causes of Uterine fibroid
While the exact cause of fibroids is not fully understood, several factors are believed to contribute to their development. Here are some of the main factors that are thought to be associated with the development of uterine fibroids:
- Hormonal factors: Estrogen and progesterone, the two hormones involved in the regulation of the menstrual cycle, are believed to promote the growth of uterine fibroids. Fibroids tend to grow during reproductive years when hormone levels are higher and typically shrink or disappear after menopause when hormone levels decline.
- Genetic predisposition: There is evidence to suggest that certain genetic mutations may be associated with the development of uterine fibroids. If your mother or sister has a history of fibroids, you may be at a higher risk of developing them.
- Family history: A family history of uterine fibroids increases the likelihood of developing them. However, the specific genetic factors involved are still being studied.
- Race and ethnicity: Studies have found that fibroids are more common in African American women compared to women of other ethnicities. Additionally, African American women tend to develop fibroids at a younger age and have larger and more numerous fibroids.
- Obesity: There is a correlation between obesity and the development of uterine fibroids. Excess body weight can lead to an overproduction of estrogen, which may contribute to fibroid growth.
- Age and reproductive factors: Uterine fibroids are more commonly diagnosed in women of reproductive age. The risk of developing fibroids increases with age until menopause. Additionally, women who have never given birth or had their first child at a later age may have a higher risk.
- Other factors: Some studies suggest that certain lifestyle factors, such as diet, may influence the development of fibroids. However, more research is needed to establish a clear link between specific dietary factors and fibroid growth.
It’s important to note that while these factors are associated with uterine fibroids, not all women with these risk factors will develop fibroids, and some women without these risk factors may still develop them. If you suspect you have uterine fibroids or have concerns about your reproductive health, it’s best to consult with a healthcare professional for an accurate diagnosis and appropriate management.
Symptoms and Diagnosis
The presence of uterine fibroids can vary widely among women. While some women may experience no symptoms at all, others may have more pronounced and disruptive symptoms. Common signs and symptoms associated with fibroids include:
- Heavy or prolonged menstrual periods: Fibroids can cause excessive bleeding, leading to prolonged periods or passing large blood clots.
- Pelvic pain and pressure: large fibroids can cause discomfort or pain in the pelvic region, lower back, or during sexual intercourse.
- Increased frequency of urination: Fibroids located near the bladder can lead to frequent urination or a sense of urgency.
- Enlarged abdomen: In some cases, fibroids can cause the abdomen to appear swollen or enlarged, leading to a change in waist size or shape.
- Anemia: Excessive bleeding from fibroids may result in iron deficiency anemia, causing fatigue, weakness, and shortness of breath.
If uterine fibroids are suspected, a healthcare provider will perform a thorough evaluation, which may include:
- Pelvic examination: A physical examination of the pelvic area to check for any abnormalities or changes in the uterus.
- Imaging tests: Ultrasound, magnetic resonance imaging (MRI), or other imaging techniques can help visualize the size, number, and location of fibroids.
- Hysteroscopy: A procedure in which a thin, lighted tube (hysteroscope) is inserted through the vagina and cervix to examine the inside of the uterus.
While fibroids are generally benign and do not always cause symptoms or complications, they can pose certain risks depending on their size, number, and location. Here are some potential risks associated with uterine fibroids:
- Heavy or Prolonged Menstrual Bleeding: Fibroids located within or near the uterine cavity can cause heavy or prolonged menstrual bleeding, known as menorrhagia. This can lead to anemia or iron deficiency.
- Pain or Pressure: Larger fibroids or those located near the bladder, rectum, or pelvic organs may cause pelvic pain, pressure, or discomfort. This can affect daily activities and quality of life.
- Urinary Symptoms: Fibroids that press against the bladder can result in frequent urination, urgency, or difficulty emptying the bladder. In some cases, this can lead to urinary tract infections.
- Bowel Symptoms: Fibroids located near the rectum can cause constipation, difficulty with bowel movements, or pain during bowel movements.
- Infertility or Pregnancy Complications: Depending on their size and location, fibroids can interfere with fertility by obstructing the fallopian tubes or affecting the implantation of a fertilized egg. Fibroids may also increase the risk of miscarriage, preterm labor, or complications during pregnancy and delivery.
- Adverse Pregnancy Outcomes: Fibroids have been associated with an increased risk of certain complications during pregnancy, such as placental abruption (separation of the placenta from the uterus), fetal growth restriction, and the need for cesarean section.
- Impact on Fertility Treatments: Fibroids may affect the success rates of fertility treatments, such as in vitro fertilization (IVF), by interfering with the implantation of embryos or reducing the effectiveness of procedures.
- Rare Complications: While rare, some fibroids can undergo degeneration, causing severe pain or fever. Extremely large fibroids may lead to hydronephrosis (swelling of the kidneys) or renal failure due to obstruction of the urinary tract.
The choice of treatment for uterine fibroids depends on various factors, including the severity of symptoms, the size and location of fibroids, the desire for future pregnancy, and overall health. Treatment options include:
- Watchful waiting: If fibroids are small, asymptomatic, or close to menopause, a healthcare provider may recommend regular monitoring without any active treatment.
- Medications: Certain medications, such as hormonal birth control, gonadotropin-releasing hormone (GnRH) agonists, or nonsteroidal anti-inflammatory drugs (NSAIDs), can help manage symptoms and reduce fibroid size.
- Minimally invasive procedures: Procedures like uterine artery embolization (UAE), myomectomy, or laparoscopic hysterectomy can be performed to remove or shrink fibroids while preserving the uterus.
- Traditional surgery: In severe cases or when fertility is not a concern, a hysterectomy (removal of the uterus) may be recommended.
It’s important to note that not all fibroids require treatment, and the risks associated with them vary from person to person. If you have uterine fibroids or suspect you might have them, it is advisable to consult with a healthcare provider who can evaluate your specific situation and provide appropriate guidance and treatment options.
