Adenomyosis

When the uterine lining grows into the muscle wall — causing heavy, painful periods.

Adenomyosis is a condition where the tissue that normally lines the uterus grows into the muscular wall of the uterus. It causes the uterus to become enlarged and can lead to heavy, prolonged, and painful periods. It is often underdiagnosed because its symptoms overlap with fibroids and endometriosis.

How Dawn Phase helps with Adenomyosis

Heavy and prolonged periods

Heavy menstrual bleeding is the hallmark symptom of adenomyosis. Periods may be significantly heavier than before or last longer than 7 days. Tracking flow intensity and duration each cycle builds a clear picture.

Severe period pain

Pain from adenomyosis is often worse than typical period cramping — described as stabbing, knife-like, or deep pressure in the uterus. It typically worsens with each passing year. Tracking pain intensity cycle to cycle can reveal this progression.

Chronic pelvic pain

Unlike typical period pain that resolves after menstruation, adenomyosis can cause pelvic pain throughout the cycle — not just during your period. Daily symptom logging helps distinguish this from phase-linked pain.

Bloating and uterine tenderness

An enlarged uterus can cause abdominal bloating and tenderness. Some women describe their abdomen feeling swollen or tender to touch, particularly around their period.

Painful sex

Deep dyspareunia — pain during sex felt deep in the pelvis — is a common adenomyosis symptom. Tracking whether pain occurs at certain cycle phases can help identify a hormonal pattern.

Frequently asked questions

How is adenomyosis diagnosed?

Adenomyosis is typically diagnosed via transvaginal ultrasound or MRI. Unlike endometriosis, it does not require surgery to diagnose. Definitive diagnosis was historically only possible after hysterectomy, but imaging has improved significantly.

Is adenomyosis the same as endometriosis?

No, though they can coexist. Endometriosis is tissue growing outside the uterus. Adenomyosis is tissue growing into the uterine muscle wall. Symptoms overlap significantly, which is why both are often underdiagnosed.

Does adenomyosis affect fertility?

Adenomyosis may affect implantation and is associated with higher rates of pregnancy complications in some studies. If you are trying to conceive, discuss this with a specialist.

What treatments are available?

Treatment ranges from hormonal management (IUD, pill, GnRH agonists) to surgical options. Hysterectomy is the only permanent cure. Treatment choice depends on symptom severity and whether future pregnancy is desired.
