What is Adenomyosis?

What is Adenomyosis?

Adenomyosis, pronounced add-en-o-my-OH-sis, is a condition that occurs within the uterus.  When lining of the uterus (endometrial tissue) grows into the myometrium (the muscular wall of the uterus) to cause adenomyosis.

The diffuse (a fancy way to say, spread out) endometrial tissue grows into the uterine wall while continuing to act normal.  The tissue behaves as it would if it lined the uterus.  With each monthly menstrual cycle, the tissue will thicken, break down and bleed. 

The result?  Heavier periods, sometimes painful periods, due to an enlarged uterus.


Did you know? Andenomyosis only occurs in 2-5% of adolescences with severely painful menstrual cycles.


There is no known cause for the disease but it, normally, disappears after menopause when monthly menstruation has stopped.  Women or AFAB, assigned females at birth, who have given birth, undergone a procedure on the uterus or are older than 40, have been observed to be more likely to develop andenomyosis.

The symptoms below are reported with those experiencing adenomyosis.  Symptoms can get worse over time but, often, no signs or symptoms can occur with just mild discomfort.



  • Heavier or prolonged menstrual bleeding with possible clotting
  • Severe cramping or sharp, knifelike pelvic pain during menstruation (dysmenorrhea)
  • Chronic pelvic pain
  • Painful intercourse (dyspareunia)
  • Tenderness or pressure in lower abdomen due to enlarged uterus


If you experience any of the above for a prolonged period, seek medical attention or contact your primary care provider.  Prolonged symptoms such as heavy bleeding could result in anemia, an iron deficiency.  Anemia can result in fatigue or feeling cold often.

    Tip: For severe cramping, warm the Private Pack vulva pad and place across your lower abdomen for that sweet feeling of relief.
