Delayed menstruation after vaccination has little to do with vaccination and may be due to pregnancy, polycystic ovary syndrome, endometritis and other causes.
1. Pregnancy: How patients are in ovulation before vaccination and have sex without contraception, the probability of pregnancy is higher. During pregnancy, the endometrium of the uterus no longer sheds, so menstruation does not come.
2. Polycystic Ovary Syndrome: The cause of the disease is still unclear, and it may be related to genetic factors, environmental factors and so on. When the patient herself has polycystic ovary syndrome, endocrine imbalance may occur, which may affect the hormone level and the phenomenon of not having menstruation.
3. Endometritis: it means that bacteria break through the defense of the cervix and invade the endometrium and inflammation occurs. Due to the stimulation of inflammation, the endometrium can be affected by hyperplasia, which leads to the phenomenon of not having menstrual periods.
The lack of menstruation after vaccination can also be seen in other reasons, it is recommended that patients go to the hospital in time to improve the relevant examination, follow the doctor’s instructions for treatment, to avoid delaying the condition.
