Women should pay attention to the 7 major reasons that lead to amenorrhea

My period comes every month, which is really annoying. But if my period suddenly stops, it will be even more annoying. Because many women think that they must have some disease if they don't have their period, but this is not the case. In order to understand the truth, some people ask why women don't have their period? What are the symptoms of irregular menstruation? The following will introduce them one by one for your reference.

Why don't women have their periods?

1. Reasons for surgery

Cervical adhesion caused by intrauterine surgery can cause menstrual blood stasis and prevent menstruation. After an abortion, changes in the body's hormones can delay ovulation and menstruation.

2. Tuberculous endometritis

When tuberculosis invades the endometrium, it will cause inflammation of the endometrium and damage it to varying degrees, resulting in scar tissue and amenorrhea. Therefore, once you have tuberculous endometritis, you must seek timely treatment.

3. Causes of pregnancy

For women of childbearing age who have had sexual life, when their menstruation is delayed, they often doubt whether it is menstruation abnormality or they are pregnant. This problem is a very common phenomenon in daily life.

4. Atresia of the lower reproductive tract

For example, in the cervix, vagina, hymen and other places, there is a part of congenital atresia, or the adhesion atresia caused by acquired damage. Although menstruation occurs, the menstrual blood will not and cannot flow out. This is called latent or pseudo-amenorrhea.

5. Ovarian causes

It is also called ovarian amenorrhea. If the menstrual period is delayed, the hormones secreted by the ovaries will act on the endometrium, causing changes, shedding and bleeding. If the ovaries cannot secrete hormones, the endometrium will not change and menstruation will stop naturally.

6. Excessive weight loss

In order to control their weight, many women take some weight loss drugs or go on an excessive diet, which causes delayed menstruation. If this situation lasts for a short time, the menstrual cycle can return to normal naturally, but for those who last for a long time, medication is often needed to restore the normal menstrual cycle.

7. Side effects of medications

Endocrine disorders after long-term use of contraceptives can also cause delayed menstruation. Doctors have also found, based on patient feedback, that the new generation of gastrokinetic drug metoclopramide, also known as domperidone, can also cause it. Since metoclopramide is not easy to pass through the blood-brain barrier, it is believed that it has no inhibitory effect on central dopamine receptors. The inhibition of central dopamine receptors reduces the amount of hypothalamic release factors entering the anterior pituitary gland, so the anterior pituitary gland secretes less gonadotropin and corticotropin, leading to amenorrhea and delayed ovulation.
