What Are Common Causes of a Hemorrhage During Pregnancy?

Bleeding in early pregnancy is a symptom of pregnancy. The causes are diverse: fetal chromosomal abnormalities, maternal hormone secretion disorders, uterine congenital abnormalities or acquired defects, immune system problems, viral infections, pregnant women with chronic diseases (such as heart disease, kidney disease, and blood diseases), overwork, stress Excessive sex, too intense sex, external impact, environmental pollution, improper medication, smoking, drinking, excessive caffeine intake, or other foods that promote uterine contraction.

Implantation of embryos is not stable until the placenta is fully formed, so many factors can cause miscarriage. When an abortion occurs, the embryo and the uterine wall are separated to different degrees. Once the blood vessels on the separation surface rupture, vaginal bleeding symptoms will occur. According to statistics from a medical study, more than 50% of pregnant women can safely survive the early pregnancy bleeding and successfully continue their pregnancy; about 30% of pregnant women may have miscarriages; another 10% of pregnant women may be ectopic or other problem. Some pregnant women worry that there will be abnormal vaginal bleeding during early pregnancy, and the baby will be unhealthy after successful pregnancy. Many studies have shown that more than half of miscarriages are caused by abnormalities in the embryo itself, which is a natural elimination. If the pregnancy can continue, the fetus is generally normal.

After vaginal bleeding occurs in the first trimester, if the pregnancy can be continued and the birth is successful, the proportion of fetal congenital abnormalities will not increase as a result.

In fact, bleeding during pregnancy is also a more common clinical situation, which can be caused by many reasons. According to the source of bleeding, bleeding during pregnancy can be divided into the following situations:

1. Maternal bleeding during pregnancy, mainly due to uterine disease or progesterone deficiency.

2. The bleeding during pregnancy caused by the embryo itself is mainly due to the problem of the embryo itself. If this is the case, the situation is not very optimistic.

3. Bleeding during pregnancy caused by external force stimulation, because during pregnancy, the uterus and abdominal cavity itself will be in a congested state and will appear very brittle. Sometimes even a slight irritation or slight movement can cause bleeding.

Early pregnancy bleeding management principles

You need to tell your doctor if you have any bleeding symptoms in the first trimester or at any time during your pregnancy. Usually minor bleeding is not considered a serious problem. But when you see redness or bleeding, especially with abdominal pain or colic, it is best to see a doctor right away, because this may be a sign of miscarriage or ectopic pregnancy. In late pregnancy, such bleeding symptoms may also be a problem with the placenta.

If vaginal bleeding occurs, you must see a doctor as soon as possible. The physician first assesses the amount of bleeding and measures blood pressure and pulse to determine if an immediate hospital stay is needed. Then the patient will be asked some relevant information, such as the date of the last menstruation, whether the menstruation is regular, whether there has been a discomfort and breast tenderness, whether it still exists, and whether there are symptoms of lower abdominal pain. Then make a further physical examination and make a preliminary judgment. If necessary, an ultrasound and blood test will be arranged to test 'beta human chorionic gonadotropin' (chorionic hormone) or lutein in serum to help diagnose whether it is a normal intrauterine pregnancy, spontaneous abortion, ectopic pregnancy or Hydatidiform mole.

For chorionic hormone tests, the value of two blood draws at 48-hour intervals is usually more valuable. For patients who are pregnant in a normal uterus, the second value is usually 66% higher than the first. Above, if the increase is not enough or there is a decline, it may be ectopic pregnancy or incomplete abortion. At this time, it is necessary to arrange uterine dilatation or laparoscopy for further diagnosis.

With the development of vaginal ultrasound, its resolution has greatly increased, which can help physicians to detect the intrauterine pregnancy sac earlier. If an intrauterine pregnancy sac is found, the chance of concurrent ectopic pregnancy is very low, only about one in 40,000. ; If no pregnancy sac is found in the uterus and chorionic hormone is above 1500 IU / L, the possibility of ectopic pregnancy will have to be considered.

Prevention of bleeding during early pregnancy

Do not wear high heels during pregnancy: Because women have weak foot muscles after pregnancy,

The weight of the body is mainly burdened by the toughness of the feet. Due to softening of the ligaments, you cannot carry weight for a long period of time. Especially in late pregnancy, if you wear high heels at this time, it is very unsafe, it is easy to fall, and at the same time, it will increase the burden on pregnant women, causing lower limb and lower back pain. It is safe to wear heelless flat shoes, but because the center of gravity falls on the heel, standing or walking for a long time may easily cause heel pain and low back pain. Therefore, it is best to wear low heel and wedge shoes with a heel of 2 to 3 cm.

Pregnant women should quit smoking and drinking: Tobacco is known to contain a variety of harmful substances, among which nicotine, tobacco tar, carbon monoxide, etc. are the most harmful to the human body. Nicotine in tobacco can accelerate the fetal heartbeat ^[2] , reduce the placental blood flow, affect fetal development, and cause malnutrition or deformity. Alcohol is even more taboo, it can cause fetal growth retardation, deformity or mental retardation. Therefore, smoking and alcohol should be avoided before and during pregnancy.

Pay attention to radiation protection: more or less appliances will have some radiation. Such as televisions, especially color TVs, the radiation and microwave radiation emitted during long hours of work can also have subtle effects on pregnant women and fetuses. Therefore, pregnant women must do a good job of preventing radiation.

Do not drink tea: Because tea contains richer caffeine, tea drinking increases pregnant women's heart rate, increases renal blood flow, increases pregnant women's heart and kidney burden, and is not conducive to the healthy development of the fetus. Therefore, women try not to drink tea during pregnancy.

Do not exercise vigorously: Vigorous exercise during pregnancy can easily lead to accidents, and if you do not pay attention, it may cause miscarriage. Therefore, pregnant women pay more attention when exercising, and walking is a good choice.

Use skin care products for pregnant women: ordinary skin care products contain plant extracts, estrogen, these are very exciting things for babies, and will affect the baby's normal development. Therefore, when pregnant, it is best for women to use skin care products designed for pregnant women to avoid affecting the fetus.
