Many women experience painful periods or irregular cycles, but sometimes these are signs of a bigger health issue. Two common conditions that affect women’s reproductive health are Endometriosis and Polycystic Ovary Syndrome (PCOS). Even though they share some symptoms, they are very different. Let’s talk about what they are, how to spot them, and how they’re treated.


“Understanding your body is the first step toward healing. Don’t ignore the signs—your health matters.”                                                                                              – Dr. Madhu Singh

What is Endometriosis?

Endometriosis happens when tissue similar to the lining of your uterus grows outside of it. This can cause pain, especially during periods. The tissue may grow on ovaries, fallopian tubes, or other organs. Since this tissue doesn’t belong there, it can lead to inflammation, scarring, and sometimes fertility issues.

Common symptoms:

  • Painful periods
  • Pain during sex
  • Pain when going to the bathroom
  • Heavy bleeding
  • Trouble getting pregnant
  • Fatigue and bloating


What is PCOS?

PCOS is a hormonal condition that affects how the ovaries work. Women with PCOS may have high levels of male hormones (androgens), irregular periods, and small cysts on their ovaries.

Common symptoms:

  • Irregular or no periods
  • Extra hair on the face or body
  • Acne or oily skin
  • Thinning hair on the scalp
  • Weight gain or trouble losing weight
  • Trouble getting pregnant


Key Differences Between Endometriosis and PCOS

Feature Endometriosis PCOS
Main Issue Tissue grows outside uterus Hormonal imbalance and cysts on ovaries
Main Symptoms Pain and heavy periods Irregular periods and hormone-related issues
Fertility Can block tubes or damage ovaries No ovulation leads to fertility problems
Pain Common (especially during periods) Not usually painful
Diagnosis Laparoscopy (minor surgery) Blood tests and ultrasound
Treatment Hormones, pain meds, or surgery Lifestyle changes, medications, fertility help

How Are They Diagnosed?

  • Endometriosis: Doctors may do a pelvic exam, ultrasound, or a laparoscopy (a small surgery to look inside and confirm the diagnosis).


  • PCOS: Doctors use blood tests to check hormone levels and do an ultrasound to look at the ovaries.


Treatment Options

Endometriosis:

  • Pain relief medicine
  • Hormone treatments (like birth control)
  • Surgery to remove extra tissue

PCOS:

  • Healthy diet and exercise
  • Birth control to regulate periods
  • Medicines to lower hormones or help with ovulation
