The common causes include -1) the post partum stage (after delivery/ childbirth), when the uterus is still large in size after delivery (the process of shrinking in size of the uterus to its normal size is called involution), 2) fibroids, 3) adenomyosis etc. These patients often complain of discomfort in the pelvic region and menstrual problems.
