Xiaoqing and her husband have been pregnant for two years, but they have not been pregnant for a long time. Every time I came home for the New Year, my mother-in-law urged me, and the words she said became more and more difficult to hear. Usually the work is busy, and I have not had much time to do a systematic inspection. During the epidemic, business stopped, and the two children decided to concentrate on pregnancy preparation, bought a bunch of ovulation test strips from the Internet, and began to prepare for pregnancy.
However, a year later, I still did not get pregnant.
The two little ones were suddenly confused, "We are both in good health, why can't we get pregnant?" So I went to the hospital and hung up the reproductive department.
After a careful consultation and examination, the doctor learned that Xiaoqing's ovarian reserve function can be found, and her lover's semen is no problem, but the problem is that Xiaolin's body mass index BMI is relatively large, reaching 35kg/m2, according to Chinese standards, it has reached the level of severe obesity. Doctors advised her to lose weight before getting pregnant.
Xiaoqing and her lover were suddenly confused: Will obesity affect pregnancy?
Obesity is only harmful to pregnancy and not beneficial!
Studies have shown that obese women take longer to conceive than normal women. When the BMI is greater than 29, the natural pregnancy rate decreases by 4-5% for every 1 increase in BMI.
01 Causes ovulation disorders
Obese patients have higher insulin levels, resulting in an increase in androgens and estrogens, a decrease in gonadotropins, leading to ovulation disorders and menstrual abnormalities.
02 Leads to decreased fertility
Obesity can cause an increase in sinus follicles and locked follicles, which may lead to depletion of ovarian reserve and a decrease in fertility.
03 Causes a decrease in egg quality
Too many fatty acids can have toxic effects on germ cells. Obesity causes oxidative stress in oocytes, which negatively affects meiosis and cytoplasmic maturation of oocytes.
An analysis of egg cells that failed IVF insemination in obese women found a high incidence of aneuploidy at meiosis. Related animal experiments have found that obesity changes the function of mitochondrial and endoplasmic reticulum in egg cells, resulting in apoptosis of granulocytes.
04 Causes a decrease in embryo quality
In IVF cycles, obese women are more likely to produce low-quality embryos and develop more slowly. Obese female blastocysts have fewer cells that nourish the ectoderm.
05 Increased risk of miscarriage
Obese women have an increased risk of miscarriage during early pregnancy compared to normal women. When the BMI > 30 kg/m2, the risk of recurrent miscarriage increases 3-fold.
06 Increase obstetric complications in pregnant women
With the increase in the BMI before pregnancy in pregnant women, the risks of gestational diabetes mellitus, premature rupture of membranes, placental abruption, caesarean section rate, macrosomia, and postpartum hemorrhage all increased accordingly.
Therefore, if you want to get a healthy baby, it is best to lose weight first and then prepare for pregnancy
When the BMI > 30kg/m2, it is necessary to lose weight.
Calculation formula: BMI BMI = square Kg/m2 of body weight/height. Do pregnant sisters need to lose weight?
