What are the reasons why girls don't have menstruation?

If menstruation is often absent, it may be caused by various reasons. In this case, you need to doubt whether you are pregnant and go to the hospital for a detailed examination and treatment.

Taking progestin-containing drugs, such as progesterone, emergency contraceptive pills, etc., can prolong the luteal phase and cause delayed menstruation. Newer generation gastrokinetic drugs may also cause delayed menstruation.

For example, uterine surgery may cause adhesions in the uterine cavity or cervix, which may prevent menstrual blood from being discharged, thereby delaying menstruation.

Obesity, excessive dieting, irregular living habits, premature ovarian failure, polycystic ovary syndrome, etc. can all cause endocrine disorders in women and lead to delayed menstruation.

Chronic hepatitis, tuberculosis, tumors, hypothyroidism, severe anemia, vitamin E deficiency, etc. often cause delayed menstruation.
