Weight gain during pregnancy is a natural and essential aspect of the development of a healthy foetus. Understanding the nuances and factors that influence this body change can help you better prepare for the nine months of gestation.<\/p>\n

 <\/p>\n

The different phases of weight gain<\/h2>\n

First trimester<\/h3>\n

During the first trimester, weight gain is often minimal, as the body adapts to the new situation. The uterus is beginning to prepare to receive the baby, but the foetus<\/strong> is still very small. On average, a pregnant woman gains between 1 and 2 kilos in the first three months. This increase includes the gain in blood volume, the formation of new fat cells and the increase in amniotic fluid.<\/p>\n

Second trimester<\/h3>\n

The second trimester is generally marked by more rapid weight gain. At this stage, the baby is growing rapidly, causing the uterus to expand significantly. Women usually gain between 5 and 7 kilos during this period. This weight gain can be attributed to a combination of foetal growth, increased blood production and increased fat<\/strong> formation, which will serve as an energy reserve for childbirth.<\/p>\n

Third trimester<\/h3>\n

The last trimester is when weight gain is most marked, with an average of 4 to 6 kilos added up to the birth. During these final months, the baby grows to around 50 cm and weighs around 3 to 4 kilos. The volume of amniotic fluid<\/strong> also increases, as does the supply of essential nutrients to support the baby until birth.<\/p>\n

Factors influencing weight gain<\/h2>\n

Body mass index (BMI) before pregnancy<\/h3>\n

InitialBMI<\/strong> plays a crucial role in determining the appropriate weight gain during pregnancy. A woman with a normal BMI (between 18.5 and 24.9) should ideally gain between 11 and 16 kilos. Those with a BMI below 18.5 should aim to gain slightly more, while those with a BMI above 25 should moderate their weight gain to between 7 and 11 kilos.<\/p>\n

Diet and physical activity<\/h3>\n

Eating a balanced diet rich in nutrients is essential for a healthy pregnancy. Foods such as green vegetables, fruit, lean proteins and whole grains should be favoured. This not only provides the nutrients needed<\/a> for the baby’s development, but also helps control weight gain. Moderate physical activity, recommended by health professionals, also helps to stabilise weight.<\/p>\n
