Pre-pregnancy check-up for second child

With the implementation of my country's two-child birth policy, many older mothers can no longer wait and are planning to have a second child. As time goes by, mothers have work experience and accumulated a lot of parenting knowledge, but they don’t know that once they are over 35 years old, the body’s physiological functions will significantly decline, and the probability of chromosomal abnormalities and the birth of deformed fetuses will gradually increase. So, what do you need to check before having a second child? ?

1. In general, you should first have a comprehensive understanding of women's health status: including nutrition, growth and development, whether there is anemia, hypertension, nephritis, hepatitis, diabetes, etc. Knowing whether there are underlying diseases is very important for the subsequent management of the entire pregnancy, which can reduce pregnancy complications, such as gestational hypertension and gestational diabetes.

2. Check the urinary system: Pregnant mothers need to go to the gynecology department for a routine leucorrhea examination to screen for Trichomonas, fungi, chlamydia, mycoplasma infection, Trichomonas vaginitis, as well as gonorrhea, syphilis and other sexually transmitted diseases; perform cervical cytology examination to eliminate cervical lesions; do B-ultrasound to understand the size of the uterus, the thickness of the endometrium, and the condition of the uterus, ovaries, and bilateral fallopian tubes. For women who have been infertile for many years, hysterography is needed to check whether both fallopian tubes are unobstructed. The above test can be carried out after menstruation, and vaginal medication, cleaning and sexual intercourse should be avoided 2 to 3 days before the test. Secondly, test the ovarian hormone in the blood to understand whether the ovaries are normal. It is usually appropriate to draw blood for testing on the 2nd to 4th day of the menstrual period, preferably on the 3rd day of the menstrual period.

3. Necessary blood tests: Blood type testing can help us understand whether there is a possibility of incompatibility between the mother and the child's blood types. If a woman's blood type is O and her husband's blood type is A or B, or if the pregnant woman is Rh negative, the titers of anti-A, anti-B and anti-D antibodies need to be measured to prevent neonatal hemolytic disease.
