Blood clots in early pregnancy

For pregnant women, if blood clots appear in the early stages of pregnancy, they must pay enough attention and seek medical attention in time, because the appearance of blood clots may be a sign of threatened abortion. If there are signs of threatened miscarriage and the pregnant woman does not take timely measures to protect the fetus, it will lead to fetal arrest. Of course, threatened abortion can be prevented through certain methods. Below, we will introduce in detail the causes, treatment and prognosis of threatened abortion in early pregnancy.

1. Reasons

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 50% to 60% of pregnancies in early spontaneous abortions 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 contractions and cause miscarriage. Infections 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.

II. Treatment

In addition to bed rest and strictly prohibiting sexual intercourse, the treatment of threatened abortion should create an environment that is conducive to stabilizing the patient's mood and relieving tension. For those with a history of miscarriage, more spiritual support should be given. If the pregnant woman's progesterone level is low, progesterone supportive therapy can be used.

3. Prognosis and Prevention

If vaginal bleeding stops, abdominal pain disappears, and B-ultrasound confirms that the embryo is alive, the pregnancy can continue. If the clinical symptoms worsen, B-ultrasound reveals that the embryo is poorly developed, and blood hCG continues to remain unchanged or decreases, it indicates that miscarriage is inevitable and the pregnancy should be terminated. During the early stages of pregnancy, you should pay attention to rest and avoid excessive fatigue. You should avoid sexual intercourse during the first three months of pregnancy and try to avoid contact with toxic and harmful physical and chemical substances in order to avoid the occurrence of threatened abortion.
