Endometriosis
Endometriosis
What it means
Endometriosis is a disease in which tissue like the lining of the uterus grows in other places in the body. The uterus is lined with tissue called the endometrium. The patches of tissue are called implants, nodules, or lesions, and they are most often found on or under the ovaries, on the fallopian tubes, behind the uterus, on the tissues that hold the uterus in place, and on the bowels or bladder. The main symptoms are pelvic pain, which often happens during a period, and infertility. Researchers do not know what causes endometriosis. Surgery is the only way to know for sure that a person has it, and the most common surgery used to diagnose it is a laparoscopy.
Endometriosis in Spanish
- Spanish term

- Gender and article
- feminine: la endometriosis
- Pronunciation

Endometriosis is spelled the same in Spanish and English. The Spanish dictionary records it as a feminine noun with a medical label, formed from endometrio and the ending -osis, and MedlinePlus en español writes la endometriosis. Endometrio (endometrium) is a masculine noun that the dictionary defines as the mucous membrane lining the uterine cavity; MedlinePlus en español explains it as el tejido que recubre el interior del útero. The same page gives two words for the organ: el útero, o matriz.
MedlinePlus en español calls the patches of tissue implantes, nódulos or lesiones, and also parches de endometriosis. Symptom words on the page include dolor pélvico (pelvic pain), cólicos menstruales (menstrual cramps) and infertilidad (infertility). The page writes the word for a menstrual period both with and without an accent, período and periodos. The surgery used for diagnosis is laparoscopia, and the fallopian tubes are trompas de Falopio. The English MedlinePlus page lists "Endo" under "Also called."

Your right to an interpreter in the United States
If English is not your primary language and you have difficulty communicating in English, you may need an interpreter or a translated document when you visit a doctor or dentist, go to the emergency room or pick up a prescription. The U.S. Department of Health and Human Services Office for Civil Rights states that two federal laws, Title VI of the Civil Rights Act of 1964 and Section 1557 of the Affordable Care Act, require programs that receive its funding to provide language access services free of charge.
You can ask when you make the appointment or at the front desk: "I need an interpreter, please." «Necesito un intérprete, por favor.»
