Hello Fitria Wahyu Kurniawati,


During pregnancy, a woman needs more calorie intake from food + -300 kj than normal needs before becoming pregnant. This intake of more calories is needed because of the physiological changes in the mother's body and the need for fetal growth. A woman's weight will increase during pregnancy and the amount of weight gain varies.


In the first trimester of pregnancy weight gain may only be 1-2 kg because in that trimester the mother often experiences emesis gravidarum which causes nausea, vomiting, so the intake of food that is not commensurate with needs. After the first trimester, the normal weight gain is 0.5 kg / week. At the end of pregnancy a woman with ideal body weight before pregnancy can gain weight 12-17 kg, while women who are thin should have gained weight 14-20 kg, women who are overweight / obese should only gain weight by 7, 5-12.5 kg.


Weight gain during pregnancy is distributed in the following cases:

Fetal weight: 2.5-4 kg
Placenta: 0.5-1 kg
Amniotic fluid: 0.5-1 kg
Breast tissue: 0.5-1 kg
Blood circulation: 2 kg
Enlarged uterine tissue: 1-2.5 kg
Subcutaneous fat: 2.5-4.5 kg

Weight gain that exceeds normal can be caused by excess food intake, fetal size larger than normal, fetus more than one (twins), many amniotic fluid, and so forth. If the normal weight gain that you experience is distributed to the fetus it can lead to greater fetal weight. Larger fetal weight causes sizes such as fetal head or buttocks to be larger than normal. The lower part of the fetus at birth is normally the head, if the size of the head is too large and disproportionate to the size of the pelvis and birth canal there can be difficulties at delivery and also the risk of greater birth canal trauma. However, if the size of the mother's pelvis and birth canal is greater than the size of the lowest part of the fetus, then this should not be a concern.


You can consult further with an obstetrician, to measure your fetal weight estimates and find out about other causes that cause excess weight gain apart from more food intake, such as gestational diabetes. Consult with your doctor about the types of good food consumed during pregnancy to obtain weight gain and ideal fetal weight. Thus the explanation from me, hopefully useful.
