What are the causes of amenorrhea?

1. Disease

Mainly including severe tuberculosis, severe anemia, malnutrition and other wasting diseases. Unique endocrine diseases, such as "obesity, reproductive incompetence, malnutrition" and so on; adrenal, thyroid, pancreatic and other effects, such as adrenal, thyroid, pancreatic and other dysfunction. The influence of these reasons may not lead to menstruation. However, as long as the disease is cured, menstruation will occur naturally.

2. Atresia of the lower reproductive tract

For example, in the cervix, vagina, hymen, labia, etc., some parts are congenitally locked, or the locked parts are caused by acquired injuries. Although menstruation occurs, menstrual blood cannot flow out. This situation is called hidden or pseudo-amenorrhea. Locking of the lower part of the reproductive tract can be completely cured after treatment by a doctor.

3. Hypoplastic reproductive organs

Some people are born without ovaries, or their ovaries are poorly developed and cannot produce estrogen and progesterone, so the endometrium cannot change regularly and there is no endometrial shedding, so there is no menstruation. Some people are born without uterus, or their endometrium is poorly developed, or their endometrium is damaged. Even if their ovaries are functioning well and their estrogen and progesterone secretion is normal, they will not have menstruation.

4. Tuberculous endometritis

This is because tuberculosis invades the endometrium, causing inflammation and damage to the endometrium to varying degrees, eventually resulting in scar tissue and amenorrhea. Tuberculous endometritis should be treated promptly without delay.

5. Pituitary or hypothalamic dysfunction

The pituitary gland can secrete gonadotropin, which can regulate ovarian function and maintain menstruation. If the pituitary gland is dysfunctional, it will affect the secretion of gonadotropin, which in turn affects ovarian function. Ovarian dysfunction can lead to amenorrhea. Hypothalamic dysfunction can also lead to amenorrhea. There are many reasons for hypothalamic dysfunction, such as mental stimulation, sadness, fear, tension, fatigue, environmental changes, cold stimulation, etc. Amenorrhea caused by the hypothalamus is more common.
