Did you know that diabetes and prediabetes may influence your risk of developing uterine fibroids? Diabetes affects an estimated 40.1 million Americans, while more than 115 million adults have prediabetes. Researchers continue to study the relationship between metabolic health and fibroid development, with growing evidence suggesting that insulin resistance may play an important role. [1, 2]
Understanding this connection can help women recognize symptoms earlier, seek appropriate care, and take proactive steps to support their overall health.
Diabetes Risk Factors
Several factors can increase your risk of developing Type 2 diabetes, including:
- Family history of diabetes
- Being overweight or obese
- Physical inactivity
- Age 45 and older
- High blood pressure
- Prediabetes
- A history of gestational diabetes
The risk of diabetes is also disproportionately higher among some racial and ethnic groups. According to the CDC, diabetes prevalence remains highest among American Indian and Alaska Native, Black, and Hispanic adults. [1.2]
The American Diabetes Association recommends routine diabetes screening beginning at age 45 and earlier for individuals with additional risk factors.
The Link Between Insulin Resistance and Fibroids
Uterine fibroids are noncancerous growths that develop within or on the uterus. Although the exact cause of fibroids remains unclear, hormones and growth factors are believed to play an important role in their development.
One area of growing interest is insulin resistance.
Insulin resistance occurs when the body’s cells become less responsive to insulin. To compensate, the pancreas produces more insulin. Researchers believe these higher insulin levels may contribute to fibroid growth through several mechanisms:
- Increased insulin may stimulate growth factors that encourage cell growth and tissue development.
- Excess insulin can influence estrogen activity, a hormone known to fuel fibroid growth.
- Insulin resistance is often associated with obesity and chronic inflammation, two factors linked to a higher risk of fibroids.
Several studies have found an association between insulin resistance and uterine fibroids, suggesting metabolic health may play a role in fibroid development. However, researchers continue to investigate exactly how these conditions interact.[3,4,5]
Prediabetes Matters Too
Prediabetes occurs when blood sugar levels are higher than normal but not yet high enough for a Type 2 diabetes diagnosis.
Because prediabetes is closely linked to insulin resistance, it may contribute to the same metabolic conditions associated with fibroid growth.
Many people are unaware they have prediabetes. The CDC estimates that more than 8 in 10 adults with prediabetes do not know they have it. [1,2]
If you have excess weight, a family history of diabetes, high blood pressure, or irregular menstrual symptoms, talk with your healthcare provider about appropriate screening.
Can Fibroids Raise Blood Sugar Levels?
Current research does not suggest that uterine fibroids directly raise blood sugar levels or cause diabetes.
However, many women with fibroids also have conditions associated with insulin resistance, including obesity, prediabetes, and polycystic ovary syndrome (PCOS).
Fibroids can also contribute to symptoms that affect overall wellness. Heavy menstrual bleeding may lead to anemia and fatigue, making it more difficult to maintain healthy habits such as regular exercise and balanced nutrition.
While fibroids do not cause diabetes, they can impact quality of life and complicate efforts to manage existing health conditions. [3]
Common Symptoms of Uterine Fibroids
Many women assume fibroid symptoms are simply a normal part of aging or menstruation. In reality, these symptoms may indicate an underlying condition requiring medical attention.
Common fibroid symptoms include:
- Heavy menstrual bleeding
- Periods lasting longer than usual
- Pelvic pain or pressure
- Frequent urination
- Constipation
- Lower back pain
- Leg pain
- Fatigue caused by anemia
- Abdominal bloating
If these symptoms interfere with your daily life, speak with a healthcare provider about a fibroid evaluation.
What Does the Research Say?
Research into the connection between diabetes and fibroids continues to evolve.
A recent study from the <Study of Women’s Health Across the Nation examined the relationship between diabetes-related factors and uterine fibroids in midlife women. Researchers found that insulin resistance may be associated with fibroid risk in some populations and that additional research is needed to better understand these complex interactions.
Researchers are also exploring whether medications used to treat diabetes, such as metformin, may influence fibroid development and growth. Some studies have reported lower fibroid occurrence among women taking metformin, though more research is needed to confirm these findings.
How Diabetes Can Affect Reproductive Health
Poorly controlled blood sugar levels can affect reproductive health in several ways.
Women with diabetes may experience:
- Irregular menstrual cycles
- Changes in ovulation
- Fertility challenges
- Increased pregnancy-related risks
Maintaining healthy blood sugar levels can support both reproductive health and overall well-being.
Steps You Can Take to Support Your Health
Whether you have diabetes, prediabetes, or fibroids, improving insulin sensitivity can benefit your overall health.
Pay Attention to Symptoms
If you notice heavy menstrual bleeding, pelvic pressure, frequent urination, worsening fatigue, or other unusual symptoms, talk with your healthcare provider.
Stay Physically Active
Regular exercise helps improve insulin sensitivity, supports cardiovascular health, and may help manage some of the risk factors associated with fibroid development.
Maintain a Healthy Weight
Even modest weight loss can improve insulin sensitivity and reduce the metabolic factors associated with diabetes and insulin resistance.
Schedule Recommended Health Screenings
Routine diabetes screening and gynecological care can help identify health concerns before they become more serious.
What to Do If You Think You Have Fibroids
If you experience symptoms such as heavy periods, pelvic pressure, frequent urination, or unexplained fatigue, speak with your healthcare provider.
Fibroids are commonly diagnosed using imaging tests such as ultrasound or magnetic resonance imaging (MRI).
If fibroids are found, treatment options depend on factors such as symptom severity, fibroid size, reproductive goals, and overall health. One minimally invasive treatment option is uterine fibroid embolization (UFE), an outpatient procedure that blocks blood flow to fibroids, causing them to shrink while preserving the uterus.
