During pregnancy, every woman faces inevitable changes in your body. Among the most obvious is weight gain caused not only by the presence of the growing fetus but also for water retention increase in circulating blood volume, increased fat increased muscle mass of the uterus, etc. The weight of the mother before pregnancy body mass index (BMI) the pattern of weight gain and total weight gain during the 9 months of pregnancy are factors that interfere directly in the weight length and reserves fat of the newborn.
Weight and fat stores are important because they can have a big impact on the baby’s health short and long-term risks influencing the child to develop health problems such as diabetes, hypertension and cardiovascular disease. The gestational weight gain also has effects on the mother, since women who gain excessive weight during pregnancy have a higher risk of becoming obese or overweight aggravate already existing. In this article, we will explain what is considered an increase desired and healthy weight during pregnancy. We will also clarify about the risks of excessive and inappropriate increase in weight.
When a woman is pregnant, her body undergoes many changes with weight gain and silhouette the most obvious. If we only count the weight of the baby, it would be expected that the mother present a minimal weight gain, about 3.5 kilos. However the weight of the fetus corresponds to only a fraction of the total weight gain of the mother. When a woman is pregnant, the following factors contribute to increase the weight:
- Average fetal weight: 3.2 to 3.6 kg
- Increased body fat reserves: 2.7 to 3.6 kg
- Increased circulating blood volume in the body: 1.4 to 1.8 kg
- Fluid retention 0.9 to 1.4 kg
- Amniotic fluid weight of 0.9 kg
- Weight gain Breast 0.45 to 1.4 kg.
- Increased uterine weight: 0.9 kg
- Placental weight: 0.7 kg
This means that a pregnant woman with a normal body weight before pregnancy should gain, on average, something around 11 to 14.5 kg until late pregnancy. Except in cases of diseases of pregnancy, preeclampsia and where there is a greater accumulation of liquids, most of the above factors varies greatly from one pregnancy to another. Usually what defines the differences between weight gain between two pregnant women is increasing fat reserves, ie how much each pregnant fat.

In the 1930s, when medicine was still practiced based on personal opinion and the theoretical logic, obstetricians indicated a maximum gain of 7 kg during pregnancy. Food restriction was a common obstetric practice for years and was based on the belief that excessive gestational weight gain led to the development of preeclampsia and other obstetrical problems.
