Uterine fibroids in African women are among the most common yet under-recognised reproductive health conditions, often developing earlier and causing more severe symptoms than in other populations.
This article explains what fibroids are, why African women are disproportionately affected, common symptoms, causes, diagnosis, and available treatment options, using evidence-based research to support the discussion.
Uterine fibroids, medically known as leiomyomas or myomas, are non-cancerous growths that develop in or around the uterus. They arise from the smooth muscle tissue of the womb and can vary in size—from as small as a seed to as large as a melon (NHS, 2023).
Fibroids usually develop during the reproductive years, particularly between the ages of 30 and 50, and tend to shrink after menopause due to reduced hormone levels (Mayo Clinic, 2024).
Why Are Uterine Fibroids in African Women More Common?
Uterine fibroids in African women are consistently reported to occur more frequently, develop earlier, grow larger, and cause more severe symptoms compared to other ethnic groups. While researchers are still studying the full explanation, several interconnected factors appear to contribute to this disparity. Research consistently shows that Black and African women are two to three times more likely to develop fibroids than women of other ethnic groups. They also tend to:
Develop fibroids at a younger age
Have larger and multiple fibroids
Experience more severe symptoms
Require surgical intervention more often (Stewart et al., 2017)
Understanding these factors is essential for improving awareness, prevention strategies, and early intervention.

1. Genetic Predisposition
Fibroids often run in families. Women with a first-degree relative (mother or sister) with fibroids have a significantly higher risk (Laughlin-Tommaso, 2018).
One of the strongest risk factors for uterine fibroids in African women is genetics. Studies show that women with a family history of fibroids are significantly more likely to develop them. If a mother or sister has fibroids, the risk increases substantially.
Research suggests that certain gene variations linked to fibroid development are more common among women of African descent. These genetic differences may influence:
How uterine muscle cells grow
How the body responds to oestrogen
How quickly fibroid tissue forms
Genetics alone does not determine whether fibroids will develop, but it may create a biological environment where abnormal uterine growth is more likely.
2. Hormonal Influence
Fibroids are hormone-sensitive growths. They depend largely on oestrogen and progesterone, two key reproductive hormones.
Several studies suggest that uterine fibroids in African women may be influenced by:
Higher lifetime exposure to oestrogen
Earlier onset of menstruation
Differences in hormone receptor activity
Greater sensitivity of fibroid cells to hormonal stimulation
Fibroids often grow during the reproductive years when hormone levels are highest and tend to shrink after menopause when oestrogen levels decline. This hormonal dependency helps explain why fibroids are rare before puberty and often stabilise later in life.
3. Vitamin D Deficiency
Vitamin D deficiency has emerged as a particularly important factor in explaining why uterine fibroids in African women are more common.
Vitamin D plays a role in:
Regulating cell growth
Controlling inflammation
Suppressing abnormal tissue proliferation
Research suggests that low vitamin D levels may increase fibroid risk and promote fibroid growth.
Women of African descent are more likely to have vitamin D deficiency because higher melanin levels in darker skin reduce the skin’s ability to synthesise vitamin D from sunlight. Limited sun exposure in colder climates can further worsen deficiency.
While vitamin D does not cure fibroids, maintaining adequate levels may help regulate uterine cell growth and support reproductive health.

4. Diet and Lifestyle Factors
Diet and lifestyle patterns may also contribute to the increased prevalence of uterine fibroids in African women.
Research has linked fibroid risk to:
High consumption of red meat
Diets low in fruits and vegetables
Obesity
Low fibre intake
Chronic stress
Excess body fat can increase oestrogen production, which may stimulate fibroid growth. Additionally, diets low in antioxidant-rich foods may reduce the body’s ability to regulate inflammation and abnormal tissue development.
Urbanisation, sedentary lifestyles, and processed food consumption may further increase risk in some communities.
Beyond biological factors, structural and social determinants of health also play a role.
In many communities, heavy menstrual bleeding and pelvic pain are often normalised, leading women to delay seeking medical care. Limited access to specialist services, cultural stigma around discussing menstrual health, and healthcare disparities can contribute to:
Later diagnosis
Larger fibroid size at detection
Increased complications
Higher rates of surgery
Health inequality may not cause fibroids directly, but it can significantly worsen outcomes.
Improving awareness, encouraging early screening, and reducing barriers to care are essential steps toward addressing disparities associated with uterine fibroids in African women.
In many African and Black communities, menstrual pain and heavy bleeding are often normalised, leading to late presentation and larger fibroids at diagnosis (WHO, 2022).
Studies show that uterine fibroids in African women are influenced by a combination of genetic predisposition, hormonal factors, vitamin D deficiency, and delayed diagnosis.
Common Symptoms of Fibroids
Some women have fibroids without symptoms. However, when symptoms occur, they may include:
Heavy or prolonged menstrual bleeding
Passing large blood clots during periods
Severe menstrual pain
Pelvic pressure or pain
Abdominal enlargement (“looking pregnant”)
Frequent urination
Constipation
Pain during sexual intercourse
Difficulty conceiving or recurrent miscarriages
Chronic heavy bleeding can lead to iron-deficiency anaemia, which is a major cause of fatigue, dizziness, and weakness among women with fibroids (NHS, 2023).
Types of Uterine Fibroids
Fibroids are classified based on where they grow:
Intramural fibroids – grow within the uterine wall (most common)
Submucosal fibroids – grow into the uterine cavity and are strongly linked to heavy bleeding and infertility
Subserosal fibroids – grow on the outer surface of the uterus, often causing pressure symptoms
Pedunculated fibroids – attached to the uterus by a stalk
Are Fibroids Cancerous?
Fibroids are benign (non-cancerous). Less than 1 in 1,000 fibroids are associated with cancerous changes, making malignancy extremely rare (ACOG, 2021).
How Are Fibroids Diagnosed?
Fibroids are usually diagnosed through:
Pelvic examination
Ultrasound scan (first-line investigation)
MRI scan for detailed mapping when surgery is considered
Can Fibroids Be Managed Naturally?
Natural and lifestyle-based approaches may help reduce symptoms and slow fibroid growth, particularly in mild cases:
Maintaining a healthy body weight
Eating a fibre-rich, plant-forward diet
Reducing red meat and processed foods
Correcting vitamin D deficiency
Managing stress and improving sleep
While these approaches are supportive, they do not eliminate fibroids completely, especially larger ones (NIH, 2022).
Medical and Surgical Treatment Options
Treatment depends on symptom severity, fibroid size, age, and fertility goals:
Pain relief and medications to control bleeding
Hormonal treatments
Myomectomy – surgical removal of fibroids while preserving the uterus
Hysterectomy – complete removal of the uterus (considered a last resort)

Raising awareness about uterine fibroids in African women can lead to earlier diagnosis, better treatment choices, and improved quality of life.
Conclusion
Uterine fibroids are a common but often misunderstood condition, especially among African women. Higher risk, earlier onset, and more severe symptoms make early awareness, routine screening, and informed healthcare decisions essential. Fibroids are not cancer, and many women live full, healthy lives with proper management. The burden of uterine fibroids in African women is higher due to a combination of genetic factors, hormonal influences, lifestyle patterns, and delayed access to healthcare.

Key Takeaway
The higher prevalence of uterine fibroids in African women is likely the result of a complex interaction between genetics, hormonal influences, vitamin D deficiency, lifestyle factors, and health inequalities. No single cause explains the difference, but understanding these contributing factors can support earlier diagnosis, better prevention strategies, and more personalised treatment approaches.
