What is the reason for early menstruation every month?

Generally speaking, women's menstruation comes at a fixed time every month, but many women experience early menstruation every month. So what exactly causes early menstruation every month? Today, let's take this opportunity to take a look with the editor.

Menstruation refers to the shedding of the endometrium, and the discharge of the shed endometrial tissue and blood from the vagina. The blood that flows out is called menstrual blood. Women and some female mammals have regular menstruation during their reproductive period. This cycle is called the menstrual cycle. Generally speaking, the amount of blood loss during a woman's menstruation is between 30 ml and 80 ml.

A woman's first menstrual period is called menarche, which marks the beginning of puberty. Women do not have menstruation during pregnancy. You will have menstruation during breastfeeding (so you need to take good contraceptive measures at this time), and menstruation will stop after menopause. Long-term use of contraceptives may lead to endocrine disorders and delayed menstruation. Based on patients' feedback, doctors also found that a new generation of gastrokinetic drug, metoclopramide, also known as domperidone, may also cause this condition. Since metoclopramide does not easily cross the blood-brain barrier, it is believed that it has no inhibitory effect on central dopamine receptors. Central dopamine receptors are inhibited, resulting in a decrease in the amount of hypothalamic release factors entering the anterior pituitary. As a result, the anterior pituitary secretes less gonadotropin and corticotropin, leading to amenorrhea and delayed ovulation.

The above are the reasons why menstruation comes early every month. If you experience the above-mentioned situation, you should go to the hospital for examination and medical treatment in time to avoid missing the best treatment time and causing the condition to worsen.
