Understanding Uterine Fibroids: Symptoms, Causes, and Advanced Management for Women

As women, our bodies undergo remarkable changes throughout life, and sometimes, these changes come with unique health challenges. One such common condition that often affects women, particularly in their reproductive years, is uterine fibroids. Also known as leiomyomas or myomas, these benign (non-cancerous) growths in the uterus can range in size from tiny seedlings to bulky masses, sometimes causing discomfort and impacting quality of life. In India, uterine fibroids are quite prevalent, affecting a significant number of women, though many may not even realise they have them.

For some, fibroids are asymptomatic, a silent presence. For others, they can lead to debilitating symptoms like heavy menstrual bleeding, chronic pelvic pain, and even fertility challenges. Understanding uterine fibroids is the first step towards seeking appropriate care and reclaiming your well-being. Authored by Dr. K. Ramalakshmi, Obstetrics & Gynecology, this article aims to demystify uterine fibroids, shedding light on their nature, symptoms, causes, and the wide array of advanced management options available today.

What Exactly Are Uterine Fibroids?

Uterine fibroids are non-cancerous muscular tumors that grow within the wall of the uterus. They are not associated with an increased risk of uterine cancer and almost never develop into cancer. Fibroids typically develop during a woman's reproductive years, often between the ages of 30 and 50, and tend to shrink after menopause when hormone levels decrease.

Types of Uterine Fibroids

• Intramural Fibroids: The most common type, growing within the muscular wall of the uterus, potentially causing it to enlarge.
• Submucosal Fibroids: Located just beneath the lining of the uterine cavity, even small ones can cause heavy bleeding and fertility issues.
• Subserosal Fibroids: Growing on the outer surface of the uterus, these can press on other organs, causing pelvic pressure or frequent urination.
• Pedunculated Fibroids: Subserosal or submucosal fibroids that grow on a stalk, which can sometimes twist, leading to acute pain.

Recognizing the Signs: Symptoms of Uterine Fibroids

The presence and severity of symptoms depend on the fibroids' size, number, and location. Many women experience no symptoms at all, discovering fibroids incidentally during routine exams. However, for those who do, symptoms can significantly impact daily life:

• Heavy or Prolonged Menstrual Bleeding (Menorrhagia): A common and distressing symptom, leading to anaemia, fatigue, and weakness. Women might soak through pads/tampons quickly or experience periods lasting longer than seven days.
• Pelvic Pressure or Pain: A feeling of fullness or heaviness in the lower abdomen, often a constant ache. Larger fibroids can press on the bladder or rectum.
• Frequent Urination: Pressure on the bladder can lead to a constant urge to urinate.
• Difficulty Emptying the Bladder: Pressure can make it hard to fully empty, leading to a feeling of incomplete voiding.
• Constipation or Difficulty with Bowel Movements: Fibroids pressing on the rectum can interfere with normal bowel function.
• Backache or Leg Pain: If fibroids press on nerves, it can cause pain radiating to the back or down the legs.
• Pain During Intercourse (Dyspareunia): Depending on their location, fibroids can make sexual activity uncomfortable or painful.
• Infertility or Miscarriage: Especially submucosal fibroids, which can interfere with implantation and pregnancy, sometimes leading to recurrent miscarriages.

When to See a Doctor

It's crucial not to ignore persistent or worsening symptoms. You should consult a gynecologist if you experience:

• Severe pelvic pain that doesn't improve with over-the-counter pain relief.
• Heavy menstrual bleeding that soaks through one or more pads or tampons every hour for several consecutive hours.
• Bleeding between periods.
• Chronic pelvic pressure or a noticeable increase in abdominal size.
• Difficulty emptying your bladder or frequent urination that disrupts sleep.
• Unexplained weakness, dizziness, or fatigue, which could indicate anaemia.

What Causes Uterine Fibroids? Understanding the Risk Factors

While the exact cause of uterine fibroids is not fully understood, research suggests a combination of factors plays a role:

• Hormones: Estrogen and progesterone appear to promote fibroid growth, explaining why fibroids often grow during pregnancy and shrink after menopause.
• Genetics: A family history of fibroids increases your risk.
• Age: Most common in women in their 30s, 40s, and early 50s.
• Obesity: Women who are overweight or obese have a higher risk.
• Diet: A diet high in red meat and low in fruits and vegetables may be associated with an increased risk.
• Vitamin D Deficiency: Some studies suggest a link between low vitamin D levels and an increased risk of fibroids.
• Early Onset of Menstruation: Starting periods at a younger age may slightly increase risk.

Modern Approaches to Managing Uterine Fibroids: Your Treatment Options

The good news is that women with uterine fibroids have a wide range of treatment options. The best approach depends on factors such as fibroid size/location, symptom severity, age, desire for future pregnancies, and overall health. At Iswarya Hospital, our experienced team of gynecologists provides personalised care, utilising state-of-the-art diagnostic tools to accurately assess your condition and recommend the most suitable treatment plan.

Watchful Waiting

If your fibroids are small, asymptomatic, or cause only mild symptoms, your doctor might recommend regular check-ups to monitor growth and symptom changes. This is often suitable for women nearing menopause, as fibroids tend to shrink naturally after this stage.

Medication Management

Medications primarily aim to manage symptoms like heavy bleeding and pain, rather than eliminating fibroids:

• GnRH Agonists (Gonadotropin-Releasing Hormone Agonists): Temporarily block estrogen and progesterone production, inducing a temporary menopausal state to shrink fibroids and alleviate symptoms. Typically short-term use.
• Tranexamic Acid: A non-hormonal medication taken during heavy bleeding days to reduce blood loss.
• Nonsteroidal Anti-inflammatory Drugs (NSAIDs): Help relieve pain associated with fibroids.
• Oral Contraceptives or Progestins: Can help control heavy bleeding and menstrual pain, though they don't shrink fibroids.
• Levonorgestrel-Releasing Intrauterine Device (IUD): Releases progestin into the uterus, significantly reducing heavy bleeding.

Minimally Invasive Procedures

These procedures offer effective alternatives to traditional surgery, often with shorter recovery times:

• Uterine Fibroid Embolization (UFE): Small particles are injected into arteries supplying fibroids, blocking blood flow and causing them to shrink.
• MRI-Guided Focused Ultrasound Surgery (MRgFUS): Uses high-intensity ultrasound waves to heat and destroy fibroid tissue, guided by MRI.
• Hysteroscopic Myomectomy: For submucosal fibroids, this procedure removes them using a hysteroscope inserted through the vagina and cervix, without external incisions.

Surgical Interventions

For larger fibroids, severe symptoms, or when other treatments are ineffective, surgical options may be considered:

• Myomectomy: Surgically removes fibroids while preserving the uterus. It's often preferred for women wishing to retain fertility. Can be performed laparoscopically, robotically, or through an open abdominal incision.
• Hysterectomy: The surgical removal of the uterus. This is the only definitive cure for fibroids, typically considered for women with severe symptoms who have completed childbearing. It can be performed abdominally, vaginally, or laparoscopically.

Living Well with Uterine Fibroids: Practical Tips and Lifestyle Advice

While lifestyle changes cannot eliminate fibroids, they can help manage symptoms and promote overall well-being:

• Maintain a Healthy Weight: Obesity is a risk factor, so maintaining a healthy weight through diet and exercise can be beneficial.
• Balanced Diet: Focus on fruits, vegetables, whole grains, and lean proteins. Limit red meat, processed foods, and high-fat dairy.
• Regular Exercise: Physical activity helps manage weight, reduce stress, and improve overall health.
• Manage Stress: Techniques like yoga, meditation, and deep breathing can help reduce stress, which indirectly impacts hormone balance.
• Stay Hydrated: Drinking plenty of water is essential for overall health.
• Iron Supplementation: If experiencing heavy bleeding, discuss iron supplements with your doctor to prevent or treat anaemia.
