What does it mean to have an enlarged uterus?

Various things: To give a good answer, more information is needed. For example, pregnancy is a cause of an enlarged uterus;however i will assume this is in the setting of being nonpregnant. The uterus can be larger because of noncancerous growths like fibroids or endometriosis, cancer, or a thicker lining from hormone irregularities. Some people can just have a larger uterus than "normal". Hope this helps some.

Variable: Enlarged uterus can mean pregnancy, past pregnancies, fibroids, adenomyosis, tumors that can be benign or cancerous. Women with enlarged uteri can have pain, abnormal bleeding, loss of urine unexpectedly and a feeling of heaviness in the pelvis. Best to be checked out by a gynecologist.

Big uterus: The uterus enlarges because something is in it that was not previously noticed. Pregnancy is the most common cause; benign tumors of the uterine muscle (fibroids) are found in about 25% of women of childbearing age.
