      Reasons for delayed menstruation and examination items

      1. Pregnancy check

      Under the premise of having sexual intercourse, when women have normal delayed menstruation, accompanied by increased frequency of urination, nausea and vomiting, changes in appetite, etc., women can consider testing whether they are pregnant. The testing method can be through early pregnancy test paper or B-ultrasound, serum and other examination methods.

      Generally speaking, you can test yourself 7-10 days after having sex. You can use early pregnancy test paper or pregnancy test stick to detect morning urine to test pregnancy. The longer the time after sex, the more accurate it will be. In short, after having sex, pregnancy can be detected as early as one week and as late as about 3 weeks.

      In the early stages of pregnancy, women will experience a series of early pregnancy reactions such as dizziness, nausea, drowsiness, and breast enlargement. They usually become more obvious 10 to 14 days after pregnancy, and will disappear on their own after three months. Therefore, if a woman has the above symptoms, she can use early pregnancy test strips and pregnancy test sticks to test pregnancy.

Cervical adhesions: There is menstrual blood, but the menstrual blood cannot be discharged normally due to adhesions from the cervix and accumulates in the Uterus Within a period of time, the patient will have periodic stomach ache , B-ultrasound examination shows that there are dark areas in the uterine cavity, and it is often necessary to go to Hospital Cervical dilation was performed. If this situation is not improved in time, it can lead to endometriosis.

      2.premature ovarian failureIt is caused by abnormal ovarian function. Often manifested as delayed menstruation, thin hair, amenorrhea and infertility. Menopausal-like symptoms such as vaginal dryness, dyspareunia, hot flashes and insomnia may occur.

      3.polycystic ovary Syndrome: In addition to oligomenorrhea, it also has three characteristics: anovulation, obesity, and hirsutism. This disease can not only cause Irregular menstruation , infertility, and may increase the risk of hypertension, diabetes, and endometrial cancer.

      4. Abnormal thyroid function: Thyroid problems seem to be more common in women. Whether it is hyperthyroidism or hypothyroidism, it will affect menstruation. In hyperthyroidism, the number of menstrual periods decreases, the amount of menstrual flow decreases, and the time between two menstrual periods becomes longer. When the thyroid function is low, menstrual bleeding will increase and the bleeding time will be long. However, in patients with long-term illness, menstruation will become less frequent or even absent.

      It is recommended that women, especially those with menstrual abnormalities, go for regular gynecological examinations so that the disease can be detected early and early treatment will be beneficial to them.

      Endocrine abnormalities can easily lead to delayed menstruation. Common polycystic ovary syndrome, premature ovarian failure leads to delayed menstruation. What to do if menstruation is delayed due to endocrine disorders? If excessive obesity, hirsutism, female infertility, acne and other symptoms occur, women should check their endocrine function.

      2. Follicle-stimulating hormone (FSH): Measuring the concentration of follicle-stimulating hormone in the blood on the third day of menstruation can be used to predict fertility. If FSH is higher than 15mIU/mL, it means poor fertility; if it is higher than 40mIU/mL, it clinically means ovarian failure.

      3. Prolactin (PRL): Women work synergistically with estrogen, progesterone, glucocorticoids, etc. during the second trimester of pregnancy. It has a certain effect on the synthesis of ovarian hormones, lutein production and dissolution. It plays an important role in fetal development and growth, especially in the formation of fetal lungs. It also plays an important role in the body's stress response.

      4. Testosterone (T): T is the most important androgen in the human body. High levels of testosterone in women are commonly seen in hirsutism, virilization, polycystic ovary syndrome, ovarian tumors, adrenal tumors, and adrenal hyperplasia.

      5. Progesterone (P): The measurement of progesterone in blood is clinically used to monitor ovulation and normal function of the corpus luteum in non-pregnant women, monitor progesterone therapy and evaluate early pregnancy, etc. It is of particular importance in judging the functional status of the corpus luteum.
