Do you want to get pregnant because of pregnancy or have a big belly because of delicious food? Overweight people are always one step behind thin people! Recently, according to a study by the Harvard School of Public Health in the United States, thin people are more likely to get pregnant than overweight people. Women who successfully lose 5 kilograms can get pregnant in an average of only 2.5 months, which is half a month faster than ordinary people or overweight people.
Furthermore, foreign media have previously pointed out that related studies have shown a strong correlation between body mass index (BMI) and pregnancy chances. When BMI is greater than 29, the chance of pregnancy decreases by 4%. Women with a BMI between 35 and 40 have a 26%–43% lower chance of getting pregnant compared to women with a BMI between 21 and 29. A BMI greater than 30 can be considered the standard for female obesity.
Therefore, for overweight people who want to get pregnant quickly, or at least increase their chances of conceiving, the first thing they need to do is lose weight. Yes, losing weight is exceptionally difficult for overweight people.
Why is it harder for overweight people to get pregnant?
Overweight people may lag behind in terms of physique and athletic ability, but it's hard to understand why they'd also be a step behind on the road to becoming mothers.
Experts say that obesity affects the chances of getting pregnant mainly because excessive obesity may affect a woman's ovulation patterns and endocrine hormones that are closely related to conception.
First, excessive obesity can cause endocrine disorders and menstrual irregularities in women, which means that ovulation is abnormal. Doctors point out that obese women have a higher chance of ovulation abnormalities, which not only include a reduced number of eggs, but also slow egg maturation and difficulty in implantation in the uterine lining, thus increasing the unfavorable factors for pregnancy.
Secondly, obesity can lead to decreased estrogen levels and increased androgen levels in women. This condition itself increases the likelihood of infertility. Furthermore, it's necessary to consider whether this hormonal imbalance is due to polycystic ovary syndrome (PCOS). PCOS is characterized by elevated androgen levels and obesity. This condition often prevents the normal release of mature eggs, thus reducing the chances of conception. Obese individuals are at high risk for this condition.
In addition, obese women are more prone to insulin resistance and hyperinsulinemia, meaning that tissues such as the liver and muscles are less sensitive to insulin. Therefore, as a self-protective mechanism, the pancreas produces more insulin to compensate. However, unlike the liver, the ovaries are abnormally sensitive to insulin. Hyperinsulinemia can stimulate the ovaries to secrete excessive amounts of male hormones, thereby affecting ovulation and leading to infertility.
Therefore, for overweight people who want to get pregnant, the first thing they should do is prepare to lose weight. However, they shouldn't rush it. Studies show that losing more than 10% of their weight within a year can also lead to menstrual irregularities, causing the opposite of the desired effect.
Pregnant women should maintain a moderate weight; being overweight or underweight is not advisable.
While it's true that overweight people shouldn't get pregnant, excessively thin people also face difficulties conceiving. I once saw a Weibo post claiming that female celebrities in the entertainment industry have difficulty conceiving because they are too slender. There's actually some truth to that.
First, excluding pathological factors, malnutrition in women can also lead to insufficient development of the uterine lining, making it difficult for fertilized eggs to implant.
Secondly, normal ovarian function requires a certain amount of fat as a foundation; otherwise, normal ovulation is difficult. This is because estrogen primarily originates from fat; insufficient fat can lead to low estrogen levels in women, preventing the ovaries from releasing mature eggs and causing difficulty conceiving.
In addition, just like obese patients, being too thin can also affect the normal menstrual cycle, leading to unstable menstruation and difficulty in getting pregnant.
Therefore, women who are too thin should increase their intake of staple foods to ensure a balanced diet. In addition, high-fat dairy products are a good choice, as they can increase the secretion of estrogen in women, helping with ovulation and increasing the chances of conception.
This shows that not only being overweight, but also being underweight can cause difficulty conceiving. Therefore, only by maintaining a balanced diet and an appropriate weight can one be a healthy expectant mother.
