PCOS vs Endometriosis: What’s the Difference?
PCOS and endometriosis are two of the most common, but most misunderstood, women’s health conditions. While they can share symptoms, they’re very different in how they affect the body. Here’s what sets them apart and how to know which one you might be dealing with.
PCOS at a Glance:
Hormonal condition
Irregular or absent periods
Acne, facial hair, scalp hair thinning
Insulin resistance and blood sugar issues
Cysts on ovaries (not always present)
Endometriosis at a Glance:
Inflammatory condition
Painful, heavy periods
Pain with sex, bowel movements, or ovulation
Fatigue, bloating (“endo belly”)
Fertility struggles from tissue growing outside the uterus
Can You Have Both? Yes - and many women do. This can make symptoms more complex, but also means you benefit from a more holistic support plan that tackles inflammation, hormone imbalance, and gut health.
If your symptoms are more pain and inflammation-based (think painful cramps, fatigue, bloating), endometriosis may be the root. If they’re more hormone and cycle-related (like acne, irregular cycles, cravings), PCOS is more likely.
Whether you’re navigating PCOS, endometriosis, or both, it can feel confusing, frustrating, and isolating. These conditions are complex - and so is your body. That’s why a personalised approach matters.
