The possibility of recurrence of endometriosis is not only related to surgery, but also to the age of the patient. For women close to menopause, the probability of recurrence decreases as a result of decreased estrogen secretion. However, for women of childbearing age, especially the secretion of estrogen is relatively strong. Under the stimulation of hormones, the incidence of endometriosis is relatively high. In particular, women who have not completely cured endometriosis are likely to re-emerge under external stimuli. For example, postpartum women are also one of the high recurrence groups. This is because in the process of pregnancy and production, the increase of the fetus will make the uterus bigger, and the endometrium will be squeezed, so the ectopic situation can happen again. In addition, whether it is a birth or caesarean section, the cervix is open, there is a certain possibility of infection, and during caesarean section, the operation may also cause scratching stimulation of the endometrium, it also a important reasons for endometriosis recurrence. So, this is why many women have a recurrence of endometriosis after production. At the same time, the cause of recurrence may also be related to mechanical stimulation such as abortion, intrauterine ring, and rectal surgery. Therefore, the standard of treatment and rehabilitation of endometriosis is not based on symptom improvement. It is also necessary to conduct regular gynaecological examination to prevent some gynecological inflammation.
