After a woman has a diagnostic curettage procedure, she will usually have her period in about a month. The process of diagnostic curettage thins the endometrium, which needs to grow after the operation. With the changes in estrogen and progesterone secreted by the ovaries after the operation, the endometrium usually adjusts after one month when it grows to about 1.2cm, which is equivalent to about one month, and when the estrogen and progesterone levels drop the endometrium will peel off, leading to the onset of menstruation. However, if an infection occurs after the procedure, leading to adhesions in the uterine cavity, it may lead to a prolonged period of menstruation or even amenorrhea. In addition, patients should pay attention to appropriate rest after the diagnostic scraping operation, given to stop bleeding and anti-infection treatment, in the diet can eat more high estrogen-containing foods, such as soy products, fresh green vegetables, etc., is conducive to the growth of the endometrium.
