My period didn't come and I felt severe back pain

Some girls will experience delayed or early menstruation, and will also experience back pain. Some people have mild back pain, while others have severe back pain, which is even unbearable. So, what are the reasons for lower back pain due to amenorrhea? Let the editor explain it to you below.

What are the reasons for lower back pain caused by amenorrhea?

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 positive; if she is not pregnant, the result will show negative. Of course, the best way to test pregnancy is to go to the hospital for a B-ultrasound examination.

2. Side effects of medications causing amenorrhea

Medicines can affect women's endocrine system. For example, taking emergency contraception, weight loss products, drainage methods and medicines can cause endocrine disorders in women, thereby affecting the menstrual period and causing amenorrhea.

(1) Emergency contraception: The main ingredients of emergency contraception are estrogen and female hormones. By taking emergency contraception, female ovulation is inhibited, 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 drug will affect the secretion of estrogen by the uterus and ovaries, 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) Drugs for abortion: Medical abortion usually involves taking the protease-level anti-estrogen drugs mifepristone and misoprostol. These drugs will inhibit the dopamine receptors in the central nervous system, reducing the amount of factors released by the hypothalamus and pituitary entering the anterior pituitary gland, thereby causing a decrease in gonadotropin and corticosteroids secreted by the anterior pituitary gland, resulting in amenorrhea and delayed ovulation. After the drainage method drugs enter the body, they will damage the uterine wall, which requires a period of repair. Generally, the menstrual period will resume in about a month after medical abortion, or the menstruation may not come for 40-50 days.

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 surgery for ovarian cysts, the uterus and ovaries need some time to repair. Some women resume their menstrual period one month after surgery.

4. Pathological factors cause amenorrhea

Pituitary tumors, hypopituitarism, premature ovarian failure, and incomplete uterine and ovarian development may all 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 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.

5. Other factors cause amenorrhea

For example, factors such as excessive mental anxiety, too much work pressure, changes in lifestyle, irregular work and rest, changes in diet, changes in the natural environment, etc. may affect endocrine function, which may cause menstruation to occur and cause delayed menstruation.
