As we all know, obesity can lead to hypertension, diabetes and other diseases and affect health, but you may not know that obesity may also affect fertility.
Let’s look at the common situation of obesity leading to female infertility.
Affect female endocrine
Obesity does lead to infertility, one of the important reasons is that obesity can affect ovulation.
Obesity can lead to elevated leptin levels, insulin resistance and other conditions in women’s bodies. If obesity persists for a long time, it will eventually lead to anovulation. Many women have irregular menstruation when they are fat, and menstruation returns to normal after losing weight, which is why.
Under normal circumstances, we use body mass index (BMI) to judge whether a person is obese. Its calculation method is:
Body mass index (BMI) = weight (kg)/height (m) squared
For example, a woman who is 1.6 meters tall and weighs 50 kilograms has a body mass index of 50/1.62, which is about 19.53.
It is generally believed that BMI ≥ 24 is overweight, BMI ≥ 28 is obese, and for women with BMI greater than 24, it is better to control their weight under the guidance of doctors, which is more conducive to pregnancy.
Affect polycystic ovary syndrome
Polycystic ovary syndrome is a common cause of infertility, and patients with polycystic ovary syndrome are often obese. The ovulation of patients with polycystic ovary syndrome has problems, obesity will also aggravate the anovulation of polycystic ovary. Therefore, if patients with polycystic ovary syndrome are overweight, doctors will suggest to lose weight first.
Many patients with polycystic ovary syndrome can ovulate naturally after losing weight and become pregnant naturally.
Affect the process of IVF
Since obesity affects natural ovulation, drugs are used to promote ovulation when doing IVF. Why do doctors still require to lose weight before starting?
The reason is that obesity will affect the sensitivity to drugs during ovulation induction.
Specifically, in the ovulation induction process of IVF, obese patients need to use more ovulation induction drugs and longer medication time to obtain similar effects to those of normal weight patients.
Controlling body weight before being a test-tube baby can not only reduce the amount of ovulation induction drugs used and save treatment costs, but also reduce liver and kidney injury caused by drugs, which is a good thing to achieve more with one stroke.
When doing IVF, in addition to the impact on the ovulation process, obesity may also affect the quality of embryos, resulting in a reduction in the rate of implantation. In other words, obese patients after embryo transfer, the chances of successful pregnancy will decrease, so weight loss can also increase the success rate of transplantation.
In short, obesity will affect pregnancy in all aspects, but we should remind everyone that scientific and healthy methods should be adopted when losing weight (insisting on exercise under the guidance of doctors, controlling diet, etc.). If extreme weight loss methods (such as taking medicine to lose weight, etc.) are selected, endocrine disorders are likely to occur, then pregnancy is still very difficult.
Whether pregnant naturally or preparing for IVF, overweight women should scientifically control their weight. In order to have a healthy baby, let’s [shut up and take your legs].
