An enlarged uterus is a symptom of a variety of medical conditions, including pregnancy, uterine fibroids and adenomyosis. It affects 1 in 10 women of reproductive-age. While the prognosis for these conditions used to be a hysterectomy, today there are minimally invasive techniques that preserve the uterus and restore quality of life.

An enlarged uterus is the primary source of “bulk” symptoms suffered in women with fibroids. These symptoms include: 

  • Pelvic pressure; distended and bloated abdomen
  • Weak bladder control, frequent urination because of bladder pressure
  • Unexplained weight gain 

As fibroids grow, the uterus, which is typically the size of a small pear (weighing not more than a quarter of a pound), can become enlarged. This growth can create a sensation of fullness in the abdomen.

In n order to accommodate fibroid growth, the uterus can extend above the pelvic bone and cause anything from a small paunch to a very distended abdomen, sometimes even giving the appearance of pregnancy. 
In fact, gynecologists often determine the size of a uterus enlarged by fibroids by referencing a comparably sized pregnant uterus (# of weeks gestational size). 

Enlarge Uterus Symptoms

Other common fibroid and adenomyosis symptoms that go hand and hand with an enlarged uterus include:

  • Heavy, prolonged or painful periods which get continually worse
  • Abdominal pressure and bloating 
  • Moderate to severe menstrual cramps
  • Mild to severe pain
  • Heavy bleeding
  • Pain during sex and loss of libido 
  • Lower back pain and pain in the back of the legs
  • Constipation 
  • Infertility

Causes & Risks



  • Adenomyosis is a condition in which the cells of the uterine lining (the endometrium) grow into the muscle wall of the uterus (the myometrium). During each menstrual cycle, these displaced endometrial cells continue to perform its usual functions and thicken, break down, and bleed within the muscle wall. The surrounding muscle swells and forms fibrous tissue in response to the irritation. This can result in an enlarged and tender uterus.



  • Fibroids is a condition in which normal uterus muscle cells start growing abnormally, forming into smooth muscle tumors that can grow very quickly. These tumors range in size from an apple seed to a watermelon or larger. A woman can have multiple fibroids in and on the uterus, and depending on their positioning and size, the fibroids may result in an enlarged uterus.



  • During pregnancy, the uterus expands between 500 and 1,000 times its normal size.


An enlarged uterus doesn’t inherently produce any health complications, but fibroids and adenomyosis can.
