Most scientists are unanimous in the opinion that for a successful conception and pregnancy, a woman must have a normal body weight. Lack of weight, as well as its excess in a negative way, affects the female reproductive function. It is impossible to disregard the fact that the trend of pregnancy after IVF is growing in the world. And a variety of factors, including weight, can affect its successful outcome.
Scientific research suggests that overweight women are less likely to have a healthy baby by about 50%, but underweight women are at the same risk.
Lack of mass
Being underweight in women planning to conceive adversely affects overall fertility. With a deficiency of body fat in the body, there are malfunctions in the ovulatory rhythm. It should be remembered that adipose tissue is a large endocrine organ that takes part in the synthesis, metabolism and accumulation of hormones. When its amount changes, different types of hormonal disorders occur. Low estrogen levels lead to infertility. A sharp drop in weight - to disruptions in the menstrual cycle.
The in vitro fertilization procedure provides for the production of hormones with medication, however, the risks may be associated with the fact that the uterus is not prepared for pregnancy, and difficulties arise during implantation of the ovum.
Overweight
Obesity is fraught with insulin resistance, which leads to hormonal disorders and anovulation. Being overweight is associated with the risk of miscarriage. Also, obese women often have premature babies.
How to calculate your optimal body weight?
To calculate your optimal weight, you can use your body mass index. BMI = m / h 2 , where:
• m - body weight in kilograms,
• h - height in meters.
Normal indicators: 18 - 25. Lack of body weight or excess are not contraindications for IVF, however, in order to increase the chances of success, it makes sense to take action. It should be borne in mind that you should not resort to extreme diets, and it is better to consult with a nutritionist first.
Weight gain during pregnancy
A woman during pregnancy adds an average of 10 - 13 kilograms. In addition to the mass of the fetus, the breast, uterus and fat reserves increase - this is how the body prepares for motherhood. Muscle and fat provide a woman with additional sources of energy.
During pregnancy, hormonal changes occur, and the woman is hungry. The Bogolyuby MC specialists emphasize that eating “for two” is not worth it, even if you really want to. It is better to pay attention to the quality of the products, their variety, and not the quantity.
There is no single correct standard as to how much should be added to the mass of a pregnant woman. However, there is everything that comes to hand and, of course, it is impossible not to look at the scales. If a woman controls weight gain, then it will be easier for her to avoid many difficulties during pregnancy, and then return to her previous weight. If you adhere to a healthy diet, "extra" pounds after childbirth go away very quickly.
For women who have a BMI within the normal range, the recommended weight gain during pregnancy is 12-16 kg. For those who have an excess of weight - 7 - 12. With multiple pregnancies (twins) - from 17 to 25 kg.
Keep in mind that the smallest weight gain is in the first trimester - 1.5 to 2.5 kg. Often, due to early toxicosis, a pregnant woman loses her appetite, and the body mass may even decrease. In the second and third trimester, a woman gains an average of about 0.5 kg in weight.
We weigh ourselves correctly
Don't jump on the scale every day. This approach is not always informative and only leads to unnecessary worries. Sufficient control weighing once a week, on an empty stomach, in the morning. Use the same scales and remember that weight gain is a priority.
