Symptoms

What are the key symptoms of adenomyosis?

The short answer

Adenomyosis more commonly causes heavy or prolonged periods and significant cramping that can feel deep, sore, or achy. Many patients describe pelvic pressure, uterine tenderness, and heaviness, sometimes with bloating or low back discomfort that tracks with the cycle.

Adenomyosis more commonly causes heavy or prolonged menstrual bleeding, along with significant cramping that can feel deep, sore, or achy. Many patients describe pelvic pressure, uterine tenderness, and a sense of heaviness, sometimes with bloating or low back discomfort that follows the cycle.

Symptoms can overlap with endometriosis, and the two conditions can occur together, so we pay close attention to both bleeding patterns and pain characteristics. When adenomyosis is suspected, we often pair a detailed history with targeted imaging (such as expert pelvic ultrasound or MRI) to get a clearer picture. Reach out to schedule a consultation so our team can help you sort out what best fits and which treatment options make sense for you.

Questions people ask next

All symptoms questions
  • Why can adenomyosis cause heavy menstrual bleeding?

    Adenomyosis can cause heavy bleeding because tissue within the uterine muscle responds to monthly hormones, triggering swelling, bleeding and inflammation. The uterus may also enlarge, and muscle contractions can be disrupted, contributing to heavier or longer periods.

  • Are heavy periods always adenomyosis?

    No, heavy periods can be a symptom of adenomyosis, but many people with heavy bleeding have a different underlying cause. Fibroids and other uterine conditions can also cause heavy bleeding and cramping, and it’s possible to have more than one issue at the same time.

  • Why does adenomyosis cause bloating?

    Adenomyosis can cause bloating because tissue growing into the uterine muscle can swell and bleed with hormonal cycles, leading to inflammation and an enlarged, tender uterus. This can create a feeling of abdominal fullness, especially around your period.

  • How do I tell fibroids from endometriosis or adenomyosis?

    Symptoms alone can’t reliably tell them apart. Fibroids most often cause heavy bleeding and pelvic pressure, endometriosis more typically causes cycle-linked pelvic pain, and adenomyosis commonly combines very heavy bleeding with intense cramping. Imaging may help clarify the cause.
