What is endometriosis?

1 min read

Endometriosis is a condition where tissue similar to the lining of the uterus (endometrial glands) grows outside the uterus, triggering inflammation. This can lead to the formation of adhesions—scar-like bands of tissue that can cause organs in the pelvic and abdominal cavity to stick together.

During a normal menstrual cycle, some menstrual blood naturally flows backward into the pelvic cavity. However, in endometriosis, for reasons that are not fully understood, this misplaced tissue causes an aggressive inflammatory response. This inflammation can lead to chronic pain, nerve involvement, and an increased risk of infertility.

Where Can Endometriosis Develop?

The most common sites are outside the uterus in the peritoneal cavity, but endometriosis can also affect:

  • The digestive system (such as the intestines or rectum)
  • The bladder
  • The lungs (though rare)

Who Is Affected?

  • 10-15% of women of reproductive age have endometriosis.
  • 25-35% of women experiencing infertility are diagnosed with the condition.
  • It can affect all age groups and ethnicities.
  • There is a genetic component, with up to 10% of cases running in families.

Learn. Improve. Maintain.

  • Learn to recognize symptoms like chronic pelvic pain, painful periods, and digestive discomfort.
  • Improve your health by seeking early diagnosis and exploring symptom management options.
  • Maintain a proactive approach with personalized care and lifestyle adjustments.

Endometriosis is often misunderstood and underdiagnosed, but the right information can empower you to take control of your health. If you suspect symptoms, consulting a healthcare provider is the first step toward better management.

General information, not a diagnosis: talk to your doctor about your own situation.
