Adenomyosis and endometriosis are different gynaecological conditions, although both can cause painful periods, pelvic pain and other symptoms that make them difficult to tell apart. The fundamental distinction is that adenomyosis affects the muscular wall of the uterus, while endometriosis involves endometrial-like tissue growing outside the uterus.
These differences affect more than where each condition occurs. They can influence the symptoms you experience, how the condition is diagnosed and which treatments may be considered. Understanding these distinctions can help you recognise why a proper gynaecological assessment is important when symptoms overlap.
Key Takeaways
- Adenomyosis affects the muscular wall of the uterus, while endometriosis develops outside the uterus.
- Both conditions can cause painful periods and pelvic pain, although their other symptoms can differ.
- Diagnosis typically involves reviewing your symptoms, a pelvic examination and imaging where appropriate.
- Treatment depends on the condition, symptom severity and your reproductive plans.
- Adenomyosis and endometriosis can occur at the same time.
What Are Adenomyosis and Endometriosis?
Adenomyosis and endometriosis are conditions involving tissue similar to the lining of the uterus, but they affect different parts of the reproductive system.
Adenomyosis occurs when this tissue is present within the muscular wall of the uterus. It can cause the uterus to become enlarged or tender and is commonly associated with painful or heavy periods.
Endometriosis occurs when endometrial-like tissue grows outside the uterus, such as around the ovaries, fallopian tubes and elsewhere in the pelvis. This tissue can contribute to inflammation, pain and, in some cases, scarring or adhesions.
This difference in location is important because it helps explain why the two conditions can produce overlapping symptoms while still requiring different approaches to diagnosis and treatment.
How Do the Symptoms of Adenomyosis and Endometriosis Differ?
Adenomyosis and endometriosis share several symptoms, particularly painful periods and pelvic pain. This overlap means that symptoms alone are not always enough to distinguish between them.
Adenomyosis is often associated with:
- Painful menstrual cramps
- Heavy or prolonged menstrual bleeding
- Pelvic pressure, tenderness or a feeling of fullness
- Pelvic pain that may extend beyond the menstrual period
- Bloating
Endometriosis is often associated with:
- Painful periods, sometimes with pain beginning before menstruation
- Chronic pelvic pain
- Pain during or after sexual intercourse
- Pain during bowel movements or urination, particularly around menstruation
- Bloating
- Difficulty becoming pregnant
It is also possible to have both adenomyosis and endometriosis at the same time. If symptoms are persistent, worsening or affecting your daily activities, a gynaecological assessment can help determine what is causing them rather than relying on symptoms alone.
How Are Adenomyosis and Endometriosis Diagnosed?
Adenomyosis and endometriosis are both diagnosed by assessing your symptoms and medical history, followed by a pelvic examination and imaging tests where appropriate. Not every woman will need every diagnostic test, as your gynaecologist will decide what is needed based on your symptoms and initial findings.
The assessment may include:
- Medical and menstrual history: Your gynaecologist will ask about the location and timing of pain, menstrual bleeding, pain during sex, bowel or urinary symptoms and any fertility concerns.
- Pelvic examination: This allows your doctor to check for tenderness, an enlarged or tender uterus, pelvic masses or other findings that could help guide further testing.
- Ultrasound: This is commonly used as an initial imaging test and can identify features associated with adenomyosis as well as some forms of endometriosis, such as ovarian endometriomas.
- MRI: More detailed imaging may be recommended when ultrasound findings are unclear or when additional information about the location or extent of disease would help guide management.
- Laparoscopy: This is not routinely required for everyone with suspected endometriosis. As a surgical procedure, it is generally considered when symptoms and other findings warrant surgical assessment or treatment. It allows the gynaecologist to directly inspect the pelvis and treat visible endometriosis during the same procedure where appropriate.
Is Treatment Different for Adenomyosis and Endometriosis?
Treatment for adenomyosis and endometriosis has some important similarities, but the options begin to differ when more targeted treatment or surgery is needed. This is largely because the tissue growth is located in different areas.
For both conditions, treatment is personalised according to your symptoms, how much they affect your daily life and your plans for pregnancy. Wherever possible, your gynaecologist will discuss the available options with you so that treatment reflects both your medical needs and what matters to you.
- Pain relief: Medications such as non-steroidal anti-inflammatory drugs (NSAIDs) may help manage menstrual and pelvic pain.
- Hormonal treatment: Hormonal contraceptives and other hormonal therapies may be used to control periods and reduce symptoms.
- Monitoring symptoms: If symptoms are mild, your gynaecologist may recommend monitoring them rather than proceeding immediately to a procedure or surgery.
If these measures do not adequately control your symptoms, treatment becomes more specific to the condition.
How Is Adenomyosis Treated?
Because adenomyosis occurs within the muscular wall of the uterus, treatment focuses on controlling symptoms while taking into account whether preserving the uterus is important.
Hormonal treatments may help manage painful or heavy periods, and other uterus-preserving treatments may be considered depending on your symptoms and individual circumstances. If symptoms are severe and other treatments have not provided sufficient relief, your gynaecologist may discuss surgical options with you.
A hysterectomy is the definitive surgical treatment for adenomyosis because the affected tissue lies within the muscular wall of the uterus. This is a significant and permanent decision, particularly because pregnancy is no longer possible afterwards. It is therefore not simply a routine next step when other treatments are unsuccessful. Your gynaecologist should discuss the implications with you carefully, understand your priorities and help you weigh the potential benefits against what the surgery would mean for you.
How Is Endometriosis Treated?
Treatment for endometriosis similarly begins with understanding how your symptoms are affecting you and what you hope to achieve from treatment. Pain relief and hormonal treatment may provide sufficient symptom control for some women without the need for surgery.
When symptoms remain difficult to manage or if surgery is otherwise appropriate, laparoscopic surgery may be considered to remove or treat endometriosis lesions, ovarian endometriomas or associated scar tissue. Decisions about surgery should also take your fertility plans into account, particularly when treatment involves the ovaries or other reproductive structures.
When Should You See a Gynaecologist for Painful or Heavy Periods?
You do not have to suspect a condition like adenomyosis or endometriosis before visiting a gynaecologist for support. You should consider arranging an assessment if you experience:
- Painful or heavy periods that interfere with your work, sleep or daily activities.
- Persistent or recurring pelvic pain, pressure, bloating or pain during sex.
- Difficulty becoming pregnant or concerns about how your symptoms may be affecting your fertility.

FAQs About Endometriosis and Adenomyosis
Can you have adenomyosis and endometriosis at the same time?
Adenomyosis and endometriosis can occur at the same time. Because the conditions also share symptoms such as painful periods and pelvic pain, a gynaecological assessment may be needed to determine whether one or both conditions are contributing to your symptoms.
Can adenomyosis or endometriosis affect fertility?
Both conditions can be relevant when assessing fertility, although having adenomyosis or endometriosis does not necessarily mean that you will be unable to become pregnant. If you are planning to become pregnant or are having fertility concerns, your gynaecologist can consider your diagnosis and reproductive goals when discussing treatment.
Can adenomyosis or endometriosis go away on its own?
Symptoms of adenomyosis and endometriosis can change over time, but neither condition should be assumed to have resolved simply because symptoms become less noticeable. If your symptoms persist, return or begin affecting your daily life, speak with your gynaecologist about whether further assessment or treatment is appropriate.
