PCOS vs. Endometriosis: Understanding the Key Differences

When it comes to women’s health, two conditions often mentioned together are Polycystic Ovary Syndrome (PCOS) and Endometriosis. While both can impact fertility and overall well-being, they are distinct conditions with different causes, symptoms, and treatments. The pelvic health physiotherapists at Triangle Physiotherapy help us break down the key differences to help you better understand them.

What is PCOS?

Polycystic Ovary Syndrome (PCOS) is a hormonal disorder that affects how the ovaries function. It is one of the most common endocrine disorders among women of reproductive age.

PCOS

Common Symptoms of PCOS:

  • Irregular or Absent Periods: Due to hormonal imbalances, women with PCOS often experience infrequent or prolonged menstrual cycles.
  • Excess Hair Growth and Acne: Elevated levels of androgens (male hormones) can lead to hirsutism (excess facial and body hair), acne, and even hair thinning on the scalp.
  • Insulin Resistance: Many women with PCOS struggle with insulin resistance, which can increase the risk of type 2 diabetes.
  • Ovarian Cysts: Despite its name, not all women with PCOS have cysts on their ovaries, but some may develop multiple small fluid-filled sacs.

What is Endometriosis?

Endometriosis is a condition where tissue similar to the lining of the uterus grows outside of it, leading to inflammation, scarring, and pain.

Common Symptoms of Endometriosis:

  • Severe Menstrual Cramps: One of the hallmark symptoms of endometriosis is intense pelvic pain that can start before and last beyond the menstrual cycle.
  • Heavy Periods: Women with endometriosis often experience unusually heavy menstrual bleeding.
  • Pain During Intercourse: Pain during or after sex is a common complaint due to the presence of endometrial-like tissue outside the uterus.
  • Chronic Pelvic Pain: Many women with endometriosis experience ongoing pelvic discomfort, even outside their periods.

How Are PCOS and Endometriosis Treated?

Since these conditions have different causes, their treatments also vary:

  • PCOS Treatment: May involve hormonal birth control, lifestyle changes, insulin-sensitizing medications (like Metformin), and fertility treatments if pregnancy is desired.
  • Endometriosis Treatment: Can include pain management (NSAIDs), hormonal therapy (such as birth control or GnRH agonists), and in severe cases, surgery to remove endometrial-like tissue.
