[|Human|] I am 53.  I have a Merina IUD that was inserted a year ago to stop my heavy periods.  I have recently had an ultrasound that indicates a thickening of my uterus, 9mm.  Apparently this is abnormal for menopausal women.  Is it abnormal for premenopausal women with this IUD?  I would have thought the IUD would prevent thickening.
[|AI|]  Hi, This thickening of the endometrium is definitely abnormal in the menopausal uterus while it is under normal limits for a premenopausal woman. IRENA contains hormone and hence helps to control the duration and amount of bleeding. It does thin the endometrium. In the current scenario, you need further monitoring to see if the IRENA is really working or not. If there is a persistent rise in the endometrial thickness, you may need to have further investigation. Hope you find this information useful. Wish you good health.
