The removal of the uterus will cause some damage to the uterine lining, which will delay menstruation, at the latest, it will not be more than 50 days, if it is more than 50 days without menstruation, it may be due to the thinness of the uterine lining or endocrine disorders, which need to be adjusted in time. The hormone and endometrial lining of the uterus will undergo some changes after the removal of the uterus, which will easily lead to an increase or decrease in the amount of menstruation, which is a normal phenomenon that does not require special treatment, and it will return to normal when the second menstruation occurs.
