Can You Have Endometriosis and Adenomyosis Together?

Exploring reproductive health is messy and often confusing. Many patients start with one diagnosis, only to realize later that their symptoms come from two different conditions. If you want to know if you can have endometriosis and adenomyosis at the same time, the answer is yes. Research shows that about 42% of people with endometriosis also have adenomyosis.

While these conditions are similar, they are separate medical issues. Knowing how they work together is the first step toward managing chronic pelvic pain and finding a treatment that actually works. Doctors sometimes call them "evil cousins" because of how often they appear together to disrupt your daily life.

Defining the Two Conditions

To understand their relationship, you have to look at what is happening inside the body. Both involve tissue that acts like the lining of the uterus, known as the endometrium.

What is Endometriosis?

Endometriosis is when tissue similar to the uterine lining grows outside the uterus. These growths are found on the ovaries, fallopian tubes, bladder, bowel, or the pelvic wall. This tissue responds to your hormones, thickening and bleeding during your period. This causes inflammation, scarring, and high levels of pain.

What is Adenomyosis?

Adenomyosis is sometimes described as "internal endometriosis." In this case, the endometrial-like tissue grows into the muscular wall of the uterus itself. This makes the uterine walls thick and often leaves the uterus enlarged or "boggy." If you have noticed your lower stomach looks swollen, learning about the causes of adenomyosis belly can help explain this specific symptom.

Why Do They Occur Together?

Scientists are still trying to figure out why these two often show up together. Some think it starts before birth during embryonic development. Others believe that "uterine trauma" from surgery or childbirth might let cells move into the muscle. Whatever the cause, the overlap is so common that doctors should check for both if a patient's symptoms don't improve after treating just one.

Having both can create a "layered" pain. You might feel the sharp, cyclical pain of endometriosis combined with the heavy, pressurized ache of adenomyosis.

Overlapping Symptoms and the Diagnosis Challenge

A major hurdle in getting help is that the symptoms look alike. This often leads to a late diagnosis or a situation where a doctor treats one condition while ignoring the other.

Identifying Shared Symptoms

Both conditions usually cause:

• Severe period cramps
• Constant pelvic pain throughout the month
• Pain during or after sex
• Fatigue and brain fog

Distinguishing Key Differences

Even with the overlap, there are unique signs. Adenomyosis is usually tied to heavy painful periods and passing large clots. Endometriosis is more likely to cause sharp, localized pain or issues with the bowel and bladder, depending on where the lesions are located.

The Role of Imaging

Spotting both conditions at once takes a specialist. A transvaginal ultrasound or an MRI can catch signs of adenomyosis, like an uneven uterine wall or small cysts in the muscle. However, endometriosis is notoriously hard to see on scans. Often, a doctor needs to perform a laparoscopy to confirm it. When a patient already has endo, an enlarged uterus on an MRI is a strong clue that adenomyosis is also there.

Treatment Considerations for Comorbidity

If you have both, your treatment plan has to cover more ground. A solution for one might not help the other.

Hormonal Suppression

Doctors often suggest birth control, progestins, or GnRH agonists. These help thin the lining and stop inflammation. For many, these treatments help by stopping the period entirely. But if your endometriosis lesions are deep, hormones might only hide the pain instead of fixing the problem.

Surgical Options

Excision surgery is the best way to remove endometriosis. However, surgery cannot "cut out" adenomyosis because it is part of the uterine muscle. If a person has endo surgery but still feels heavy pressure and has bleeding, adenomyosis is likely the reason. For those who are done having children and have severe symptoms, a hysterectomy is the only cure for adenomyosis. It is important to remember that a hysterectomy does not cure endometriosis that has spread outside the uterus.

Holistic and Multidisciplinary Care

Since both conditions cause inflammation, many people feel better by using pelvic floor physical therapy, changing their diet, and finding ways to manage pain. You have to treat the nervous system's response to pain just as much as the physical tissue.

The Importance of Detailed Symptom Tracking

Because these symptoms are so tangled, tracking your cycle is a powerful tool. When you see a doctor, being able to explain the difference between your "sharp endo pain" and your "heavy adenomyosis pressure" can help you get an MRI or a better treatment plan faster.

An endometriosis tracker app helps you log pain, how much you bleed, and any digestive issues. This turns your experience into data that a doctor can use to advocate for your care.

Managing the Emotional Toll

Managing one chronic illness is hard enough; two can feel impossible. It is frustrating when a treatment for endo doesn't stop the heavy bleeding from adenomyosis. Finding a community of people who have both can help you feel less alone. You aren't imagining things—your body is simply dealing with a complex medical situation.

Summary of Key Takeaways

• About 42% of people with endometriosis also have adenomyosis.
• Endometriosis is outside the uterus; adenomyosis is inside the uterine wall.
• Detailed MRIs are getting better at identifying both.
• You may need multiple types of treatment since endo surgery doesn't stop adenomyosis.
