In addition to pregnancy, what other reasons are there for not having menstruation? Be alert to these diseases

Everyone knows that menstruation will stop after pregnancy, but there are many other reasons for the absence of menstruation besides pregnancy. The most important thing that cannot be ignored is some disease factors, common ones include uterine diseases, such as endometrial tuberculosis, premature ovarian failure, etc.

1. Uterine amenorrhea Problems with the uterus can lead to amenorrhea, such as congenital absence of the uterus, uterine hypoplasia, illness during childhood involving the endometrium, adhesions or scarring. These patients have no abnormal ovarian function, and other female physical signs develop normally, but they have no menstruation. After the onset of menarche, they are prone to endometrial tuberculosis, endometrial schistosomiasis, endometrial suppuration, etc., or the basal layer of the endometrium is scraped during curettage, which cannot respond to ovarian hormones and causes secondary amenorrhea.

2. Ovarian amenorrhea Women have menstruation because the hormones secreted by the ovaries act on the endometrium, causing it to change, then fall off, and bleed. If the ovaries cannot secrete hormones, the endometrium will not change, and menstruation will stop naturally. Common reasons for the inability of the ovaries to secrete hormones include congenital ovarian dysplasia, premature ovarian failure, etc.

3. Pituitary amenorrhea The human pituitary gland is located under the brain. Although it is very small, it is an important part of the endocrine organs that control the whole body. When the pituitary function changes, the female ovarian function will decrease. Common pituitary diseases include tumors and hypopituitarism. Stimulation of the central nervous system The human central nervous system includes the brain and hypothalamus. These two parts directly manage the activity of the pituitary gland and indirectly control ovarian function. Once the central nervous system is stimulated, or the hypothalamus is stimulated, changes in ovarian function will cause amenorrhea.
