Bleeding at 37 weeks of pregnancy

Vaginal bleeding after 37 weeks of pregnancy is quite serious. It may be caused by problems with the fetus in your womb. Therefore, you should go for a prenatal check-up. In this way, you can accurately know the real cause of your vaginal bleeding and develop a suitable treatment plan based on the cause of the disease. If it is a threatened miscarriage, you must find a way to protect the fetus.

Threatened abortion refers to a small amount of vaginal bleeding before 28 weeks of pregnancy, followed by paroxysmal lower abdominal pain or back pain. Pelvic examination shows that the cervix is ​​not dilated, the fetal membranes are intact, no products of pregnancy are expelled, and the size of the uterus is consistent with the gestational age. If symptoms worsen, miscarriage may become inevitable.

Termination of pregnancy before 28 weeks is called miscarriage. If the pregnancy ends naturally before 12 weeks, it is called early miscarriage, and if the pregnancy ends naturally between 13 and 27 weeks, it is called late miscarriage. According to statistics from different regions, different classes and different ages, the incidence of spontaneous abortion is between 15% and 40%. About 75% occur before 16 weeks of pregnancy, and 62% occur before 12 weeks of pregnancy.

Abortion goes through a series of processes from its beginning to its end. According to its different stages, it can be given different diagnostic names, namely: threatened abortion, inevitable abortion, incomplete abortion, complete abortion, and missed abortion.

(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 associated with 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.

(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 kidney deficiency, or excessive sexual intercourse after pregnancy, or frequent miscarriages that damage kidney qi. Kidney deficiency can cause Chong and Ren meridians to become unstable, causing the fetus to lose its anchorage, 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.
