The difference between miscarriage bleeding and menstruation

When miscarriage occurs, there will be bleeding, which is very different from normal menstrual bleeding. This is something that all female friends need to pay attention to. Some female friends did not realize they were pregnant and they were prone to miscarriage after engaging in strenuous exercise or other unexpected events. At this time, it is important to distinguish whether it is miscarriage bleeding or menstrual bleeding.

The difference between miscarriage bleeding and menstruation

1. What are the differences between abortion bleeding and menstruation?

Generally speaking, the amount of bleeding during miscarriage will be much less than that of menstruation, so just using a sanitary pad will be enough. At the same time, miscarriage bleeding also has a certain cyclical pattern. Generally speaking, as long as the bleeding occurs between two menstrual periods, it is likely to be miscarriage bleeding. During a miscarriage, the color of the blood can be pink, dark brown, or bright red. Female friends may experience lower back pain, abdominal distension, fetal movement, and slight lower abdominal pain. In addition, women who have miscarriage bleeding may experience symptoms such as abdominal pain and loss of appetite.

2. Causes of miscarriage bleeding

Embryonic factors: Embryonic chromosomal abnormalities are the main cause of miscarriage. Examination of offspring from early abortions found that 50%-60% had chromosomal abnormalities. Chromosomal abnormalities in either spouse can be passed on to offspring and lead to miscarriage. Chromosome abnormalities include numerical abnormalities and structural abnormalities. In addition to genetic factors, infections, drugs and other adverse effects can also cause chromosomal abnormalities in offspring, often resulting in miscarriage before 12 weeks of pregnancy.

Maternal factors :

2.1. Systemic diseases: High fever in systemic infection can promote uterine contraction and cause miscarriage. Infections such as Treponema pallidum, influenza virus, cytomegalovirus, mycoplasma, chlamydia, toxoplasma, herpes simplex virus, etc. can cause fetal chromosomal abnormalities and lead to miscarriage. Ischemic and hypoxic diseases such as heart failure, severe anemia, hypertension, chronic nephritis and severe malnutrition can also lead to miscarriage in expectant mothers.

2.2. Endocrine abnormalities: Luteal insufficiency can lead to early miscarriage. Hypothyroidism and severe diabetes with uncontrolled blood sugar can also lead to miscarriage.

2.3. Abnormal immune function: Immune factors related to miscarriage include the spouse's tissue compatibility antigens (HLA), fetal antigens, blood type antigens (ABO and Rh) and the mother's autoimmune status.
