When the endometrium is 0.7cm, it may be a physiological phenomenon or a disease, and the final determination needs to be determined by staging and clinical symptoms. 1. Under normal circumstances: proliferative stage (ovulation): 8~10mm; secretory stage (premenstrual stage): 10~15mm; menstrual stage: <5mm; menopause: <5mm. 2. In pathological conditions: if the endothelium is less than 7mm in the proliferative phase (ovulation), less than 10mm in the secretory phase, more than 5mm in the menstrual phase, and more than 5mm in the menopausal phase, all of them belong to pathological conditions. If it is accompanied by problems such as irregular menstruation, abnormal bleeding, or a family history of endometrial, ovarian, or breast cancer, it needs to be taken fully seriously, and if necessary, a scraping test is needed to exclude serious conditions such as endometrial tumors or even endometrial cancer. Therefore, 0.7cm of endometrium may be a disease, and it is necessary to look at different stages to determine whether the thickness is abnormal or not. In addition, it needs to be judged according to whether there are clinical symptoms. If there are abnormal bleeding, menstrual abnormalities and other discomforts, it is recommended to go to the hospital for consultation.
