Endometrial thickening of 1.2cm may be a normal physiological phenomenon, and clinically it is not an indication of the absolute need for curettage. Before menstruation or after ovulation, the endometrium can reach 1.2cm, and if there are no other clinical symptoms, there is no need for scraping. If the endometrium is thickened by 1.2cm and the bleeding is not serious, it can be treated with medication, such as progesterone capsules 100mg twice a day. Taking progesterone may cause dizziness, so you should refrain from hazardous work while taking the medication. During the period of taking the medicine, you should strictly follow the doctor’s instructions and take it under the doctor’s guidance, and if there is abnormal vaginal bleeding or discomfort, please go to the hospital for treatment in a timely manner.
