PCOS (polycystic ovary syndrome) and uterine fibroids are both common, both hormone-related, and both frequently misunderstood. Yes, you can have both. Here is how to distinguish them and what having both means for management.
Key Differences
Location: Fibroids are in or around the uterine wall. PCOS involves the ovaries. Hormone profile: Fibroids are primarily estrogen-driven. PCOS is characterised by androgen excess and insulin resistance. Cycle effects: Fibroids typically cause heavy, prolonged periods. PCOS typically causes irregular or absent periods.
Can You Have Both?
Yes. They can co-exist independently. Some overlap in risk factors exists — insulin resistance associated with PCOS elevates IGF-1, which can promote fibroid growth. Women with PCOS who have estrogen exposure from anovulatory cycles (cycles without ovulation, creating unopposed estrogen) may have a hormonal environment that also supports fibroid development.
Management Overlap
Importantly, many lifestyle interventions benefit both conditions: anti-inflammatory, low-glycaemic diet, regular exercise, weight management, and blood sugar stability. If you have been diagnosed with both, confirm the diagnosis of each with appropriate imaging (ultrasound for fibroids; ovarian ultrasound + hormone panel for PCOS) and work with a gynaecologist who treats both conditions.
