What is endometrial hyperplasia?

Cell growth: Hyperplasia means that there are more cells than there normally should be. The endometrium (lining of the uterus) undergoes cyclic changes, which result in mensturation. However, sometimes, the lining doesn't obey the central instructions, and begins to grow on its own. This is called hyperplasia. It can be simple, complex or atypical. The latter is a precursor to cancer.

Good question: Endometrial hyperplasia is the excessive proliferation of endometrial cells, which are the cells lining the inside of the uterus. It is often driven by excess estrogen and is usually treated medically with Progesterone therapy (pills or iud) or surgically with a hysterectomy.

Hormonal imbablance: Hormonal imbalance and heredity are likely to blame.

Estrogen excess: Endometrial hyperplasia commonly stems from estrogen excess. Excess estrogen usually comes from excessive fat tissue in our own bodies or from long periods of anovulation (skipping periods).
