What if a girl's period doesn't come?

Menstruation is a normal physiological phenomenon for every woman. Women without normal menstruation are unhealthy. Moreover, menstruation is also everyone’s best friend. Once the menstruation is delayed, we will also worry whether there is something wrong with our body. Next, let’s take a look at the reasons why women’s menstruation is delayed.

1. Pregnancy causes amenorrhea

If a woman has sex, she can use an early pregnancy test strip to test her urine 7 days after her period is delayed. If she is pregnant, the result will show a positive result; if she is not pregnant, the result will show a negative result. Of course, the best way to test pregnancy is to go to the hospital for a B-ultrasound examination.

2. Side effects of treatment drugs cause amenorrhea

(1) Emergency contraception: The main ingredients of emergency contraception are estrogen and female hormones. By taking emergency contraception, it inhibits female ovulation, thereby affecting the fusion of egg cells and male sperm, achieving the purpose of contraception. However, if you take too much emergency contraceptive, the ingredients in the medicine will affect the secretion of estrogen by the uterus and ovaries, and the uterine wall cannot grow normally, and the endometrium is thin, which will cause a decrease in menstrual flow or even amenorrhea.

(2) Weight loss products: For example, weight loss products containing hormone drugs generally contain thyroid hormones. Improper use of weight loss products can easily cause menstrual disorders in women, resulting in symptoms of irregular menstruation or amenorrhea, affecting normal menstruation. In more serious cases, it may cause infertility.

3. Surgical treatment causes amenorrhea

The postoperative period will be affected. For example, intrauterine surgery may cause cervical adhesions, resulting in menstrual blood stasis in the uterus, resulting in amenorrhea and delayed menstruation.

(1) Artificial abortion: Artificial abortion generally includes vacuum aspiration and curettage. If the curettage is not performed properly, it is easy to cause damage to the cervix or damage the basement membrane of the uterine wall, resulting in adhesion of the internal os of the cervix or adhesion of part of the endometrium, thus causing amenorrhea.

(2) Surgical treatment of ovarian cysts: After ovarian cyst surgery, the uterus and ovaries need some time to repair. Some women resume their menstrual period one month after the surgery.

4. Pathological factors cause amenorrhea

(1) Pituitary factors: The absence of menstruation caused by this condition is also called pituitary amenorrhea. The pituitary gland is located just below the brain. Although it is small in size, it is responsible for controlling the endocrine system of the entire body. If the function of the pituitary gland changes, it can also cause ovarian failure. Common pituitary diseases include tumors and hypopituitarism.

(2) Central nervous system factors: The central nervous system controls the activities of the pituitary gland and indirectly controls the female ovaries, including the human brain and hypothalamus-pituitary gland. When the nerve center is over-strained, the ovaries change and cause amenorrhea. Hypothalamic pituitary tumors can also cause amenorrhea.

(3) Uterine and ovarian factor: also known as ovarian amenorrhea. If the uterus and ovaries cannot secrete growth hormone, the uterine wall will not change, and the uterine wall will not fall off. As a result, the uterine wall will not change, and the menstrual period will naturally stop. For example, congenital uterine and ovarian hypoplasia, premature ovarian failure, etc. may cause amenorrhea.

(4) Uterine factor: also called uterine amenorrhea. If women have uterine problems, they may also develop amenorrhea. The most common ones are congenital absence of uterus, incomplete uterine development, or childhood diseases that invade the uterine wall, resulting in adhesions or scars. Although the ovaries are very good and female characteristics develop normally, there is no menstruation. If menstruation is not present for a long time after the menstrual period has occurred, such as due to tuberculosis of the uterine wall, schistosomiasis of the uterine wall, suppuration of the uterine wall, or when the dermis of the uterine wall is scraped off during curettage, the uterus and ovarian growth hormone cannot be responded to and secondary amenorrhea will occur.
