What causes spontaneous abortion?

Spontaneous abortion may be caused by chromosomal abnormalities, endometrial abnormalities, abnormal hormone levels, immune factors, etc.

Causes of spontaneous abortion:

1. Chromosomal abnormality: Chromosomal abnormality is a common cause of spontaneous abortion, usually due to chromosomal abnormality during fertilization or division of the embryo. Chromosomal abnormality may cause serious impact on the development of the embryo, thus leading to spontaneous abortion.

2. Abnormal endometrium: Abnormal endometrium is too thin or insufficient to support embryo growth, which can easily lead to miscarriage. Abnormal endometrium may be caused by uterine fibroids, adenomyosis, endometrial polyps or other uterine diseases.

3. Abnormal hormone levels: Progesterone and progesterone are the two main hormones that maintain pregnancy. If the levels of these two hormones are abnormal, the endometrium may be insufficient to support the growth of the embryo, leading to spontaneous abortion.

4. Immune factors: Common clinical factors include abnormal cardiolipin antibodies, abnormal antinuclear antibodies, abnormal blood type immune antibodies, abnormal T lymphocytes, etc.

Notes on spontaneous abortion:

After a miscarriage, you need to pay attention to rest more and eat light food, avoiding spicy and irritating foods such as peppers and ginger. You should also keep the vulva clean and dry, change underwear frequently, and refrain from sexual intercourse within one month after a miscarriage to avoid uterine infection. If you have multiple miscarriages, it is recommended to go to the hospital in time, complete relevant examinations, and treat according to the cause.
