Endometrium thickness should not exceed how many millimeters in non-postmenopausal women, and in postmenopausal women it should not exceed how many millimeters?

• A. 12 / 6
• B. 14 / 8
• C. 16 / 10
• D. 18 / 12

Answer: (B)

Endometrial thickness on ultrasound is driven by hormone exposure, so the limits differ by menopausal status. In women who are not postmenopausal, the lining thickens during the cycle and can approach about 14 millimeters at its peak; this value is used as a practical upper limit to distinguish normal cyclic thickening from potential pathology. In postmenopausal women, the endometrium should be much thinner because circulating estrogen is reduced, and a thickness around 8 millimeters is used as a threshold above which further evaluation is typically considered to rule out hyperplasia or cancer. Therefore, the best thresholds are approximately 14 millimeters for non-postmenopausal women and 8 millimeters for postmenopausal women.
