Reasons for delayed menstruation

1. 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. How to rule out pregnancy and how to determine whether it is a menstrual disease are the first issues that need to be clarified. First, determine whether you are pregnant. If your menstrual cycle has always been normal, with no signs of delay, and there are some signs of pregnancy, you should use an early pregnancy test strip to test your urine on the fifth day after your delayed period (or the fifth day calculated from the start of your period). If the test result is positive, you should have a gynecological pelvic examination. If the cervix changes to purple-blue, the uterus is full or enlarged, and there may be accompanying symptoms such as breast tenderness and nausea, you can be diagnosed with pregnancy. Of course, B-ultrasound can also quickly determine whether you are pregnant.

2. Side effects of drugs

Endocrine disorders after long-term use of contraceptives can also cause delayed menstruation. Doctors also found, based on patient feedback, that a new generation of gastric motility drug, metoclopramide, also known as domperidone, may also cause this condition. Since metoclopramide does not easily cross the blood-brain barrier, it is believed that it has no inhibitory effect on central dopamine receptors. Central dopamine receptors are inhibited, resulting in a decrease in the amount of hypothalamic release factors entering the anterior pituitary. As a result, the anterior pituitary secretes less gonadotropin and corticotropin, leading to amenorrhea and delayed ovulation.

3. Caused by surgery

(1) Menstruation after surgical or medical abortion is determined by the degree of recovery of the endometrial wall, which is likely to cause delayed menstruation.

(2) Uterine surgery may cause cervical adhesions, which may lead to menstrual blood stasis and thus delay menstruation.

4. Others

Such as psychological factors such as mental tension, stress, environmental changes, and some diseases that affect endocrine system. Can cause delayed menstruation.

To treat irregular menstruation, the cause of the disease should be identified first, and then symptomatic treatment can be given. Traditional Chinese medicine believes that menstrual fluid comes from the kidneys, so the key to regulating menstruation is to nourish the kidneys. By conditioning the kidney to be sufficient and the essence and blood to be abundant, menstruation will naturally be regulated. The method of tonifying the kidney is mainly to replenish essence and blood. The function of the spleen is to produce blood. Nourishing the spleen and stomach can replenish the body's blood supply. The spleen-strengthening method focuses on strengthening the spleen and raising yang. The purpose of soothing the liver and regulating qi is to regulate qi and unblock qi and blood. If qi and blood are in harmony, menstruation will be regulated. The method of soothing the liver requires understanding the main symptoms of depression.
