As we mentioned in previous articles during the last stage of the menstrual cycle normally a layer of endometriosis lining in the inside of the uterus is expelled, known as menstruation blood but instead some of the endometriosis tissues growing somewhere in the body causing endometriosis. Endometriosis also reacts to hormonal signals of the monthly menstrual cycle by building up tissue, breaking it, and eliminating it through the menstrual period. In this article, we will discuss what is endometrial hyperplasia.

I. Definition
Endometrial hyperplasia is defined as abnormal thickening of the endometrium caused by excessive cell growth. It normally is accompanied by endometrial cells irregularly and cystic expansion of glands.

It is caused by the result of continuous stimulation of the endometrium by high level of estrogen and insufficient level of progesterone produced by the ovary. This type of abnormality often occurs to woman in perimenopause stage, because her menstrual cycle now becomes irregular and she is no longer ovulates in every cycle.

II. Types
There are 4 different types of endometrial hyperplasia depending on the level of over growth of endometrial cells.
1. Simple

2. Simple atypical

4. Complex atyical
Significant abnormality in the endometrium cells' nuclei as well as over growth of the endometrium cells in the endometrium glands.
