What is the cause of threatened miscarriage at 20 weeks of pregnancy?

Threatened abortion refers to some signs of spontaneous abortion around 20 weeks of pregnancy. Clinically, it will mainly manifest as heavy vaginal bleeding, accompanied by abdominal pain, nausea and vomiting. At this stage of 20 weeks of pregnancy, the body needs protection the most. If you don't take good care of it in time, it is very likely to cause the complete loss of the embryo and affect the normal health of the body, so you must understand how to protect it in normal times.

1. What is threatened miscarriage ?

Threatened abortion refers to some signs of spontaneous abortion before 20 weeks of pregnancy. Clinically, it may manifest as a small amount of vaginal bleeding. Depending on the amount of bleeding and the time it accumulates in the vagina, the color may be bright red, pink or dark brown. Sometimes accompanied by mild lower abdominal pain, a feeling of sinking, back pain and abdominal distension. According to traditional folk sayings, the main evidence of threatened abortion is "seeing blood". After rest and treatment, the abdominal pain disappeared and the pregnancy continued. If the abdominal pain gradually intensifies or the amount of bleeding increases, miscarriage may become inevitable. Traditional Chinese medicine calls threatened abortion "fetal leakage" and "fetal movement disorder".

2. What are the causes of threatened miscarriage ?

There are many causes of threatened abortion, such as abnormal fertilized egg, endocrine disorders, placental dysfunction, blood type incompatibility, maternal systemic diseases, excessive mental stimulation, reproductive organ malformations and inflammation, trauma, etc., all of which can lead to threatened abortion.

Whether threatened miscarriage will lead to miscarriage often depends on whether the embryo is abnormal. If the embryo is normal, after rest and treatment, the cause of miscarriage is eliminated, the bleeding stops and the pregnancy can continue. But most miscarriages are caused by fetal abnormalities, so miscarriage will eventually occur.

About half of patients with threatened abortion will eventually suffer miscarriage, which may lead to infection or even sepsis and death due to excessive bleeding.

During the gynecological examination, the cervix is ​​not dilated, the amniotic sac is not ruptured, the size of the uterus is consistent with the month of amenorrhea, the urine pregnancy test is positive, and the ultrasound examination shows fetal heart rate and fetal movement waves. If the embryo is normal and the cause of the miscarriage is eliminated, the bleeding will stop, there will be no uterine contractions, and the pregnancy can continue.

3What are the precautions for threatened abortion ?

1. Live a regular life :

A peaceful daily life is the best, such as getting more fresh air in the morning, doing appropriate activities, ensuring 8 hours of sleep a day, and taking a nap if conditions permit. Do not be too lazy (such as sleeping too much) nor be too tired (such as lifting heavy objects or climbing dangerous places). If you relax, your Qi will stagnate, leading to difficult labor; if you work too hard, your Qi will weaken, leading to fetal injury and miscarriage. Develop the habit of regular bowel movements every day to ensure smooth bowel movements, but avoid using laxatives.

2. Pay attention to personal hygiene :

Change clothes frequently and take a bath frequently, but avoid taking a tub bath or swimming. Pay special attention to the cleanliness of the genitals to prevent bacterial infection. Clothes should be loose and belts should not be tight. You should usually wear flat shoes.

3. Choose the right diet :

Food should be easy to digest. Especially choose foods rich in various vitamins and trace elements, such as various vegetables, fruits, beans, eggs, meat, etc. People with weak gastrointestinal function should be cautious when eating cold foods, such as mung beans, white fungus, lotus seeds, etc. People with yin deficiency and excessive fire should be cautious when eating foods that are easy to cause internal heat, such as rooster, beef, dog meat, carp, etc.

There are many folk dietary recipes that are very effective in preventing habitual abortion and threatened abortion. Here are two of them:

1) Add 50g lotus seeds and longan pulp to a slow-cooked soup, and 100g yam to cook into porridge. Start eating it after pregnancy, 1 to 2 times a day. It is suitable for those with vaginal bleeding, lower abdominal pain, sore waist and legs, pale tongue with white fur, and a history of habitual miscarriage.

2) Roast 3 pumpkin stalks and 6 lotus stalks together until they turn yellow, grind them into powder, take it in 3 doses with hot water, and finish it in one day. It is suitable for patients with blood-heat type threatened abortion with fetal movement and abdominal pain, vaginal bleeding, bright red color, red face and dry mouth, fever in the five parts of the body, and short and red urine after several months of pregnancy.

4. Keep a happy mood :

Gynecologists believe that spontaneous abortion is caused by hyperexcitability of the subcortical centers of pregnant women. Experiments have shown that the functional state of the nervous system plays a decisive role in abortion. Therefore, during pregnancy, one should be mentally relaxed, avoid all kinds of stimulation, and use a variety of methods to eliminate tension, boredom, and fear in order to harmonize emotions.

5. Be careful to avoid sexual intercourse :

For pregnant women who are prone to spontaneous abortion, sexual intercourse should be avoided within three months of pregnancy and after seven months. Those with habitual abortion should strictly prohibit sexual intercourse during this period.

6. Regular prenatal check-ups :

Regular prenatal checkups should begin in the second trimester so that doctors can detect and address abnormalities in a timely manner and provide guidance for pregnancy care.

7. Receive medication or hospitalization under the guidance of a doctor .

4. What health care measures should be taken for threatened abortion?

The first three months of pregnancy are an unstable period, and the placenta will not function fully until about three months. Therefore, the placental function and ovarian function in the early stage of pregnancy are not yet complete, and the secretion of progesterone is insufficient. Progesterone is the so-called tocolytic hormone. In the case of insufficient tocolytic hormone, the first three months of pregnancy are in an unstable period. In addition, the first three months is an important period for the development of the fetal neural brain pipeline. Expectant mothers must also pay special attention to avoid hindering the development of the fetus's central nervous system. The following four points are the general principles that need to be paid attention to in the early stages of pregnancy:
