When is the unterus lining to thick?

The uterine lining, or endometrium, can become excessively thick due to hormonal imbalances, often related to elevated estrogen levels without sufficient progesterone. This condition is known as endometrial hyperplasia and can occur in women who are perimenopausal, have polycystic ovary syndrome (PCOS), or are on hormone replacement therapy. Thickening can lead to abnormal bleeding and may increase the risk of endometrial cancer if not addressed. Regular monitoring and consultation with a healthcare provider are essential for management.
