What is bleeding during the first week of pregnancy?

The first week of pregnancy is the most critical time. During this period, the fetal position of pregnant women is not very stable, so they must not do any strenuous exercise or physical labor. They should try to stay in bed and rest as much as possible. They can only engage in appropriate activities after the early pregnancy. However, many people find that they have vaginal bleeding one week into pregnancy, which is very likely caused by threatened abortion.

1. Chromosomal abnormalities

Chromosomal abnormalities are the main cause of miscarriage. Chromosome abnormalities include two categories: quantitative abnormalities and structural abnormalities. Studies have shown that early spontaneous abortion has

50% to 60% of pregnancies have chromosomal abnormalities. If one of the couple has a chromosomal abnormality, it can be passed on to the offspring and may cause miscarriage or recurrent miscarriage.

2. Maternal factors

(1) Systemic diseases: High fever during systemic infection can induce uterine contraction and cause miscarriage; infection with certain known pathogens such as Toxoplasma, herpes simplex, Mycoplasma hominis, Ureaplasma urealyticum, and cytomegalovirus are related to miscarriage; ischemic and hypoxic diseases such as heart failure, severe anemia, hypertension, chronic nephritis, and severe malnutrition in pregnant women can also lead to miscarriage.

(2) Endocrine abnormalities such as luteal insufficiency, hypothyroidism, uncontrolled diabetes, etc.

(3) Abnormal immune function.

(4) Severe nutritional deficiencies.

(5) Bad habits such as smoking, alcoholism, excessive coffee drinking, or use of drugs such as heroin.

(6) Adverse factors in the environment such as formaldehyde, benzene, lead and other harmful chemicals.

(7) Uterine defects such as congenital uterine malformation, submucous uterine fibroids, intrauterine adhesions, etc.

(8) Trauma such as abdominal compression or rapid impact, even surgery, excessive sexual intercourse, etc.

(9) Emotional trauma such as excessive fear, sadness, anger, etc.

3. Male's mycospermia TORCH infection

Traditional Chinese medicine believes that the occurrence of this disease is mainly due to the instability of Chong and Ren meridians, which cannot absorb blood and nourish the fetus. Because Chong is the sea of ​​blood and Ren governs the fetus, if the Qi of Chong and Ren is solid, the fetus will be supported and nourished, and the fetus can grow and develop normally. On the contrary, diseases such as fetal leakage and fetal movement disorder may occur, which lead to the mechanism of Chong and Ren instability, which is caused by weak Qi and blood, kidney deficiency, blood heat, and trauma.

(l) Deficiency of Qi and blood: The patient is usually weak, with a long-term deficiency of the spleen and stomach, and insufficient Qi in the middle, which makes it impossible to transform food and water into fine particles and send them to the heart to produce blood; or after a long-term illness or a serious illness, the patient is physically weak, with insufficient Qi to carry the fetus and insufficient blood to nourish the fetus, thus leading to symptoms such as fetal movement disorder or fetal leakage.

(2) Kidney deficiency: congenital deficiency of kidney qi, or excessive sexual intercourse after pregnancy, or repeated miscarriages that damage kidney qi. Kidney deficiency can cause the Chong and Ren meridians to become unstable, causing the fetus to lose its anchor, thus leading to restless fetuses or miscarriage.

(3) Blood heat: After pregnancy, Yin blood gathers in the blood sea to nourish the fetus, which causes Yang Qi to be excessive. Or, after pregnancy, the woman develops a fever, which causes the internal heat to disturb the blood sea, forcing the blood to flow abnormally, damaging the fetus and causing fetal leakage and restless fetal movement.

(4) Trauma: Falls, sprains, or excessive exertion can damage Qi and blood, affecting the Chong and Ren meridians, resulting in inability to nourish and carry the fetus, leading to fetal movement disorders.
