  • What exactly is endometriosis?
    MedlinePlusMay 2026

    Endometriosis is a condition where tissue that normally lines the inside of your uterus grows in other places in your body, like on your ovaries, fallopian tubes, or bowels. These patches of tissue can cause pain and other problems because they bleed during your period just like the tissue inside your uterus does.

  • Why does the tissue grow outside my uterus?
    MedlinePlusMay 2026

    Doctors don't know exactly why this tissue grows outside the uterus, so it's not something you did or didn't do. Researchers are still studying the causes of endometriosis.

  • How common is endometriosis among people who menstruate?
    MedlinePlusMay 2026

    Endometriosis is fairly common and can affect anyone who menstruates, but the exact number of people with it isn't known because it can be hard to diagnose. Many people have it without realizing it.

  • Are there any risk factors I should be aware of?
    MedlinePlusMay 2026

    You have a higher risk if a close family member has endometriosis, if your period started before age 11, or if your periods are heavy and last more than 7 days. Your risk is lower if you've been pregnant before or started your period later in your teenage years.
