Weight Gain during pregnancy happens due to increase fluids, more blood in the body, your uterus thickens, expands, and grows right along also placenta is created to nourish your baby the entire time, amniotic acid where baby floats around. Most women should gain somewhere between 25 and 35 pounds during pregnancy. Most will gain 2 to 4 pounds during the first trimester, and then 1 pound a week for the rest of the pregnancy. Gaining too little weight puts babies at risk of having a low birth weight, which increases their risk of diabetes, heart disease, high blood pressure and obesity later in life. A pregnancy is divided into trimesters: the first trimester is from week 1 to the end of week 12, the second trimester is from week 13 to the end of week 26, and the third trimester is from week 27 to the end of the pregnancy.
If you’re starting pregnancy at a healthy weight, expect to gain 1 to 5 pounds in the first trimester and about 1 pound per week for the rest of your pregnancy. “It’s very reassuring that babies born to mothers who restricted their weight gain during pregnancy were not at increased risk for harm, doctors currently don’t have specific tools to help pregnant women restrict weight gain, and so the type of program in the study “may be a solution in the future.” said Dr. Saima Aftab, the medical director of the Fetal Care Center at Nicklaus Children’s Hospital in Miami.
The calorie requirements for early pregnancy won’t change much from your usual diet, but they will increase as pregnancy progresses. Losing weight, on the other hand, isn’t appropriate for pregnant women who were at a healthy weight before pregnancy.Fortunately, growing research suggests that losing some weight during pregnancy might be possible and even beneficial for some women who are extremely overweight or obese (have a BMI over 30).
If you’re obese, you can still have a healthy pregnancy and delivery. Obese women have a greater risk of pregnancy complications such as preeclampsia and gestational diabetes. But new research shows that obese women can safely exercise and diet to lose weight without any negative impact on their baby’s well-being. Food like beans and legumes, citrus fruits and juices, whole grains, dark green leafy vegetables, poultry, pork, fish and shellfish are healthy to eat during pregnancy.
