What is the link between uterine fibroids and hormonal imbalance?
Estrogen dominance, an imbalance caused by excess estrogen in the relative absence of progesterone, can cause the uterine lining to grow unchecked. This can lead to the growth of tough fibrous, non-cancerous lumps called fibroids. While the average fibroid is an undetectable lump in the wall of the uterus, about the size of a hen’s egg, larger fibroids often cause irregular bleeding and heavy or painful periods. Fibroids are the most common physical reason for excessive bleeding during menstruation.
