The signs and symptoms of endometriosis can vary, and they don’t always correlate with the stage. Some people with stage 4 endometriosis may have few or no symptoms, while others have many.
Everyday HealthCauses and Risk Factors of Stage 4 Endometriosis
- Retrograde menstruation: This is when menstrual blood, including endometrial tissue, flows backward into the fallopian tubes instead of out of the body.
- More exposure to estrogen: This may be from early menstruation or short periods.
- Immune system dysfunction: The immune system might fail to prompt the body to remove endometrial tissue that is growing outside the uterus.
- An overactive inflammatory response: This happens when the immune system reacts to endometrial implants outside the uterus.
- Direct transplantation: This is when endometrial cells attach to other areas of the body after a surgery, such as a C-section.
- Age (25 to 50)
- Genetics or a family history of endometriosis
- Not having had children
- A diet high in red meat and trans fats
- Menstruation issues, such as short cycles, heavier flows, or longer periods
- Getting your first period before age 11
How Is Stage 4 Endometriosis Diagnosed?
- Amount of deep and superficial implants
- Number and severity of adhesions
- Presence of chocolate cysts in the ovaries (growths filled with old blood)
- Pelvic exam: Your provider feels for large growths or scars behind your uterus.
- Ultrasound: This imaging test, done with a vaginal wand or device placed on your stomach, uses sound waves to create a picture of your organs.
- MRI: Magnetic resonance imaging, or MRI, takes a more detailed picture of your body’s insides.
- Laparoscopy: To perform a laparoscopy, a surgeon makes two or three small incisions in your abdomen and inserts a camera to look for lesions and implants. During surgery, they may take small samples of suspicious tissue to check in the lab.
Endometriosis Staging
Treatment and Medication Options for Stage 4 Endometriosis
Medication Options
Medication for stage 4 endometriosis focuses on relieving pain and managing hormone levels. Hormone therapies can slow endometrial tissue growth and prevent new implants.
- Birth control pills: These control estrogen and progesterone levels and can be right for those who are not trying to get pregnant.
- Levonorgestrel-releasing intrauterine devices: These may help with pelvic pain. (Mirena is an example of one.)
- Progestins: These stop menstrual periods and the growth of endometrial tissue.
- Gonadotropin-releasing hormone (GnRH) antagonists: These limit ovarian hormone production.
- GnRH agonists: These stop ovarian hormones.
- Aromatase inhibitors: These lower estrogen levels.
- Nonsteroidal anti-inflammatory drugs: These include ibuprofen (Advil), and naproxen (Aleve).
- Opioids: In rare cases, morphine or other opioids may be prescribed for severe pain.
Surgery
- Laparoscopy: In this minimally invasive procedure, endometrial tissue and scar tissue are removed via small incisions.
- Laparotomy: This requires a larger incision to remove tissue and is used less often.
- Hysterectomy: In this procedure, the uterus is removed to stop endometrial tissue growth.
- Oophorectomy: Here the ovaries are removed to stop hormone production.
Complementary and Integrative Therapies
- Acupuncture
- Pelvic floor physical therapy
- Chiropractic care
- Exercise
- Anti-inflammatory diets

The Takeaway
- Stage 4 endometriosis is the most severe stage of this chronic disease, with symptoms including increased pain, implants outside the pelvis, and extensive scar tissue.
