What is the cause of amenorrhea?

There are many reasons for female amenorrhea. First of all, it is related to the age of women. Secondly, if they are exposed to adverse mental stimulation, it is also easy to cause amenorrhea in women. In addition, pituitary diseases and ovarian amenorrhea are also easy to cause amenorrhea in women. If you have had multiple abortions, it is easy to cause uterine amenorrhea. If it is not due to normal physiological amenorrhea, you should go to the hospital for examination in time.

1. Amenorrhea caused by mental stimulation

This is a common cause of menstrual disorders or even amenorrhea in women. It is mainly due to changes in emotions, such as stress from study, work and life, boredom, depression, excessive tension, major mental stimulation, etc., which affect the function of the hypothalamus through the neuroendocrine pathway of the cerebral cortex-thalamus-hypothalamus, or through the brain-limbic system, resulting in abnormal secretion of gonadotropin-releasing hormone in the hypothalamus, thus leading to menstrual disorders or even amenorrhea.

2. Amenorrhea caused by pituitary diseases (such as pituitary adenoma)

Pituitary adenoma is a common benign intracranial tumor, which mainly originates from the anterior lobe of the pituitary gland and is more common in people aged 30 to 40 years old. After suffering from pituitary adenoma, abnormal secretion of pituitary hormones can cause a series of metabolic disorders and organ damage. The compression of the tumor can also lead to low secretion of other pituitary hormones, causing low function of related target lines, thereby leading to corresponding functional disorders.

3. Ovarian amenorrhea

When amenorrhea occurs due to low levels of ovarian sex hormones and the endometrium does not undergo cyclical changes, it is called ovarian amenorrhea. Common causes include premature ovarian failure and polycystic ovary syndrome.

Premature ovarian failure: Generally, women’s ovarian function will slowly decline after the age of 40. However, some women suffer from amenorrhea due to genetic factors, autoimmune factors, abnormal regulation of galactose metabolism, radiotherapy and chemotherapy, infection, strong emotional stimulation, certain immune drugs, etc., which may lead to depletion or destruction of ovarian follicles, or premature ovarian failure due to surgical removal of the ovaries.

4. Uterine amenorrhea

Excessive curettage during multiple artificial abortions or damage to the endometrium due to curettage during postpartum or post-abortion bleeding can lead to intrauterine adhesions and cause amenorrhea or reduced menstruation. Certain gynecological diseases such as post-abortion infection, puerperal infection, endometrial tuberculosis infection, and infections caused by various intrauterine surgeries can also cause amenorrhea. Certain surgeries, such as various cervical conization surgeries due to cervical intraepithelial neoplasia, can also cause adhesion and stenosis of the cervical canal, which can also lead to amenorrhea or dysmenorrhea. If these symptoms occur, you need to go to the hospital for effective treatment in time to avoid affecting your endocrine system and fertility.
