What Is Adenomyosis, and How Do I Know If I Have It?

Some women spend years assuming their painful periods are simply something they have to tolerate. Heavy bleeding. Intense cramping. Pelvic pressure. Exhaustion during every cycle.

They adapt. Plan around it. Push through it. And often, no one has ever explained that there may actually be a name for what they’re experiencing: adenomyosis.

At the Institute for Gynecology Minimally Invasive and Robotic Surgery, Yitzhack Asulin, MD, FACS, FACOG, specializes in diagnosing and treating complex gynecologic conditions such as adenomyosis using advanced minimally invasive approaches. 

What exactly is adenomyosis?

Adenomyosis occurs when endometrial‑like tissue — tissue similar to the lining of your uterus — begins growing into the muscular wall of the uterus itself. That may not sound dramatic at first, but it changes how your uterus behaves.

Instead of remaining neatly contained where it belongs, this tissue becomes embedded within your uterine muscle. As your hormones fluctuate during your menstrual cycle, the tissue still responds, which can lead to inflammation, swelling, heavy bleeding, and significant pain.

One way to think about it is this: Your uterus becomes irritated from within its own muscle wall. That internal irritation is often what creates the deep, heavy, aching symptoms many women describe.

Adenomyosis vs. endometriosis — What’s the difference?

These two conditions are often confused because they can cause many of the same symptoms, including pelvic pain, cramping, and heavy periods. The difference comes down to where the tissue is growing.

With adenomyosis, tissue similar to your uterine lining grows within the muscular wall of the uterus itself. This often leads to heavy bleeding, pelvic pressure, and a uterus that feels enlarged or tender.

With endometriosis, similar tissue grows outside your uterus on structures such as your ovaries, fallopian tubes, bladder, bowel, or surrounding pelvic tissue. Endometriosis is often associated with severe pelvic pain, painful intercourse, infertility, and pain that extends beyond your menstrual cycle.

Some women have one condition. Others have both at the same time.

Because the symptoms overlap so much, distinguishing between them isn’t always simple. That’s one reason specialized evaluation matters. Proper diagnosis helps guide the most effective treatment plan rather than simply treating symptoms generically.

Signs adenomyosis may be affecting you

Not every woman experiences the same symptoms, but there are some common patterns. Many women with adenomyosis experience:

  • Very heavy menstrual bleeding
  • Severe menstrual cramping
  • Pelvic pressure or fullness
  • Chronic pelvic pain
  • Pain during intercourse
  • Bloating or abdominal heaviness
  • Fatigue related to heavy bleeding

Some women describe their periods as feeling “different” from normal cramps — heavier, deeper, more constant, or more physically draining. Others notice that their uterus feels enlarged or tender, and in many cases adenomyosis can actually cause your uterus to become enlarged over time.

While adenomyosis is most commonly diagnosed in women in their 30s and 40s, it can affect younger women. It’s also more common in women who’ve given birth, although it can occur in anyone with a uterus.

How we diagnose adenomyosis 

Imaging such as an ultrasound or MRI can sometimes reveal changes in the uterine muscle that suggest adenomyosis, though identifying the condition isn’t always straightforward. That’s one reason experience matters.

At the Institute for Gynecology Minimally Invasive and Robotic Surgery, Dr. Asulin focuses on comprehensive gynecologic evaluation and advanced minimally invasive treatment options for complex pelvic conditions. 

How Dr. Asulin can help

Your treatment depends on the severity of your symptoms, your future fertility goals, and the extent of the condition.

Some women improve with medication or hormonal management. Others benefit from minimally invasive procedures designed to reduce symptoms while preserving healthy tissue whenever possible.

For women with severe or persistent symptoms, robotic and minimally invasive surgical techniques may offer significant relief with smaller incisions, less discomfort, and faster recovery compared to traditional open surgery.

Dr. Asulin specializes in minimally invasive and robotic gynecologic surgery, enabling many women to receive highly advanced care through a more precise, less invasive approach.

If heavy bleeding, pelvic pain, or severe cramping have started interfering with your quality of life, schedule a consultation with Dr. Asulin at the Institute for Gynecology Minimally Invasive and Robotic Surgery in Englewood, New Jersey. You don’t need to continue living with unexplained symptoms.
