08 Jun Adenomyosis vs Fibroids: How Symptoms Differ
Adenomyosis and fibroids are two common gynaecological conditions that can cause similar symptoms, including heavy periods, pelvic pain, and menstrual cramping. However, they are different conditions that affect the uterus in different ways and may require different treatment approaches. An accurate diagnosis is important to ensure the most appropriate management plan.
Key takeaways
- Adenomyosis and fibroids are different conditions but often cause similar symptoms.
- Heavy menstrual bleeding and painful periods can occur with both conditions.
- Fibroids are non-cancerous growths within the uterus, while adenomyosis occurs when endometrial tissue grows into the muscular wall of the uterus.
- Imaging such as ultrasound or MRI may help distinguish between the two conditions.
- Treatment depends on your symptoms, diagnosis, and individual treatment goals.
What is the difference between adenomyosis and fibroids?
Although adenomyosis and fibroids both affect the uterus, they develop differently.
Adenomyosis occurs when tissue similar to the lining of the uterus grows into the muscular wall of the uterus. This can cause the uterine muscle to become enlarged and inflamed, leading to painful and heavy menstrual periods.
Fibroids, also known as uterine fibroids or leiomyomas, are non-cancerous growths that develop from the muscle of the uterus. They can vary greatly in size, number, and location.

How are the symptoms different?
Many symptoms overlap, which is why these conditions can sometimes be difficult to distinguish without specialist assessment.
| Symptom | Adenomyosis | Fibroids |
| Heavy menstrual bleeding | ✓ Common | ✓ Common |
| Painful periods | ✓ Often severe | ✓ May occur |
| Chronic pelvic pain | ✓ Common | Less common |
| Pelvic pressure | Sometimes | ✓ Common, especially with larger fibroids |
| Enlarged uterus | ✓ Diffuse enlargement | ✓ Depending on fibroid size |
| Frequent urination | Less common | ✓ More common with larger fibroids |
| Constipation | Less common | ✓ Can occur if fibroids press on the bowel |
While these patterns are common, symptoms vary between individuals. Some women with either condition may have very few symptoms, while others experience significant disruption to daily life.
Can you have both adenomyosis and fibroids?
Yes. It is possible to have both conditions at the same time.
Because the symptoms overlap, diagnosing both conditions can sometimes be challenging. In these situations, a thorough clinical assessment and appropriate imaging are important to determine which condition is contributing most to your symptoms.
How are adenomyosis and fibroids diagnosed?
Diagnosis usually begins with a detailed discussion about your symptoms and medical history, followed by a gynaecological assessment.
Depending on your situation, investigations may include:
- Pelvic ultrasound
- MRI scan
- Review of previous imaging and test results
These investigations help identify the cause of your symptoms and guide treatment recommendations.
Do adenomyosis and fibroids require different treatments?
Treatment depends on several factors, including:
- Your symptoms
- The severity of the condition
- Your age and stage of life
- Your treatment goals
- Previous treatments you have tried
Non-surgical management may include hormonal treatment, pain management, or ongoing monitoring.
Where surgery is appropriate, treatment options differ depending on the diagnosis. For example, myomectomy may be considered for selected patients with fibroids, while hysterectomy may be discussed for women with severe adenomyosis who have completed their family.

Why an accurate diagnosis matters
Because adenomyosis and fibroids can produce similar symptoms, treatment should not be based on symptoms alone.
A correct diagnosis helps ensure that treatment is appropriate for your condition and personal circumstances. It also allows you to better understand what to expect and discuss the most suitable options with your specialist.
When should you see a specialist?
If you are experiencing heavy periods, ongoing pelvic pain, painful periods, or pressure symptoms that are affecting your quality of life, it may be worth seeking specialist advice.
A consultation can help determine whether your symptoms are related to adenomyosis, fibroids, another gynaecological condition, or a combination of conditions.
