What is the reason for missing menstruation?

What is the reason for missed menstruation? This is a question that many women are confused about. The normal menstrual cycle of women is generally 28 to 30 days. It is still normal to be ahead of schedule or delayed by about 7 days. The length of the cycle varies from person to person. However, if the menstruation is usually regular, if the menstruation is delayed for more than 7 days, it is best to go to the hospital for a check-up. The following experts will introduce this issue to you, the reasons for missed menstruation:

Experts have listed the causes of missed menstruation into the following four situations:

1. Pregnancy factors

Reasons for missed menstruation: You can use the early pregnancy test strip to test urine after 7 days of delayed menstruation. If it is positive, it is very likely that you are pregnant. If it is negative, it is the opposite. However, if you are pregnant, there will be other symptoms such as nausea, breast pain, etc. Many women use the test strip improperly, which will also affect the normal results. It is recommended that the best way is to go to the hospital for a urine test and abdominal B-ultrasound examination.

2. Gynecological disease factors

Cervical adhesion: There is menstrual blood, but the menstrual blood cannot be discharged normally due to adhesion of the cervix, and accumulates in the uterus. The patient will have periodic abdominal pain, and B-ultrasound examination can show dark areas in the uterine cavity. Cervical dilation is often required in the hospital. If this situation is not improved in time, it will lead to endometriosis.

Premature ovarian failure: It is caused by abnormal ovarian function. It is often manifested as delayed menstruation, infrequent menstruation, amenorrhea and infertility. It may also cause vaginal dryness, dyspareunia, hot flashes and insomnia, which are similar to menopausal symptoms.

Polycystic ovary syndrome: In addition to infrequent menstruation, it also has three characteristics: anovulation, obesity, and hirsutism. This disease can not only cause menstrual disorders and infertility, but also increase the risk of hypertension, diabetes, and endometrial cancer.

3. Side effects of birth control pills

Endocrine disorders after taking contraceptives can also cause delayed menstruation. In the outpatient clinic of the gynecological hospital, according to the patient's feedback, it was also found that the new generation of gastrokinetic drug metoclopramide, also known as domperidone, may also cause it. Because 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 causes a decrease in the amount of hypothalamic release factors entering the anterior pituitary gland, so the secretion of gonadotropin and corticotropin by the anterior pituitary gland decreases, leading to amenorrhea and delayed ovulation. This is also one of the reasons for the absence of menstruation.

4. Other psychological factors

The reasons for delayed menstruation also include psychological factors, such as mental tension, stress, environmental changes and other psychological factors, some diseases that affect endocrine, etc. All of them can cause delayed menstruation.

Experts remind: If menstruation is delayed only 1-2 times occasionally and there are no other accompanying symptoms, it does not fall into the category of menstrual disorders. When the interval between menstrual cycles is more than 35 days, it is called oligomenorrhea, and when menstruation stops for more than 3 menstrual cycles, it is called amenorrhea. Because of the lack of ovulation after amenorrhea, it can also lead to osteoporosis, endometrial hyperplasia and other problems, which must be taken seriously. It is recommended to go to the hospital for examination and treatment.
