What are the causes of irregular menstruation in women? There are two reasons for irregular menstruation in women.

Many women's problems

There are two main reasons for irregular menstruation:

1. Caused by organic diseases or drugs: including inflammation, tumors, developmental abnormalities, malnutrition of local reproductive organs; intracranial diseases; other endocrine dysfunctions such as thyroid and adrenal cortex dysfunction, diabetes, Sheehan's disease, liver diseases; blood diseases, etc. Those who use drugs for the treatment of mental illness; endocrine preparations or intrauterine contraceptive devices may have irregular menstruation. Some professions such as long-distance runners are prone to amenorrhea. In addition, some abnormal bleeding during pregnancy is often mistaken for irregular menstruation.

2. Caused by neuroendocrine dysfunction: mainly due to unstable or defective function of the lower hindbrain-stomach-ovary axis, that is, menstrual disease.

Female workers working in factories may be exposed to certain industrial toxins, especially those engaged in the production of chemical raw materials, artificial fibers, or the manufacture of carbon tetrachloride, cellophane and other products, who may be exposed to toxic substances such as toluene, xylene, and carbon disulfide.

Among them, carbon disulfide can increase the chance of miscarriage in women. Gasoline can also cause menstrual cycle disorders, aggravate menopausal symptoms in menopausal women, and induce pregnancy poisoning.

Therefore, female car drivers and female workers engaged in rubber, artificial leather, paint, dye, pharmaceutical, printing and other work will suffer from gynecological diseases such as menstrual abnormalities.

Medical staff generally have a good understanding of menstruation and its diseases

In addition, women working in flight services are often affected by factors such as lack of oxygen at high altitudes, jet lag, irregular lifestyles, etc., and may also experience menstrual abnormalities such as early or late menstruation, secondary amenorrhea, etc. This has become an unspeakable distress for many stewardesses.

Vigorous exercise can delay menarche and easily lead to amenorrhea, which is common in ballet dancers and female athletes. If a girl receives regular professional training from the age of 10, her menarche can be delayed by 5 months for every year of training. Girls who learn ballet from an early age may lose weight, delay puberty and stop menstruating.

A foreign survey shows that a considerable proportion of female athletes under the age of 18 have menstrual abnormalities, most of which are manifested as late menstruation, irregular cycles, secondary amenorrhea, etc. Medical experts believe that this phenomenon is mainly due to intense exercise inhibiting the function of the hypothalamus, preventing the hypothalamus from secreting progesterone-releasing hormone, thereby interfering with the pituitary gland's release of gonadotropin in a normal cycle, leading to menstrual cycle disorders or amenorrhea.

Women who are frequently exposed to noise, radiation, or engage in mentally stressful work may also experience menstrual abnormalities to varying degrees.

There are many occupational factors that affect women's menstruation. Women should strengthen labor protection, have regular physical examinations, and seek medical treatment in time if they find abnormal menstruation, find out the cause, and receive effective treatment; if necessary, they should change their occupation to ensure good health.
