Pregnancy brings weight gain. We all know that, but how do you know when you\u2019re gaining too much weight?\nSometimes it feels like you\u2019re in control, but sometimes it feels like your pregnancy weight gain just takes off.\nHow Much Weight Should You Gain During Pregnancy?\nThere\u2019s not a clear cut answer to this question. It is different for everyone. However, your doctor can give you a range that is likely best for you. This range is based on your health and pre-pregnancy weight.\nThe expert recommendations look like this:\n\nFor women of normal weight, according to your body mass index (BMI), you should gain between 25 and 35 pounds.\nIf you\u2019re underweight, you\u2019ll want to gain a little more, 28 to 40 pounds.\nIf you\u2019re overweight or obese, you should gain a little less, around 11 to 25 pounds.\n\nKeep in mind that these are averages. Everyone has different health concerns that can affect their weight gain, such as gestational diabetes or the size of the baby.\nThe most important thing is to stay healthy during your pregnancy. You don\u2019t need to \u201ceat for two.\u201d You only need about 300 extra calories a day to give yourself and your baby the necessary nutrients. That\u2019s an extra sandwich a day.\nAim to eat the most nutritious food you can as often as you can. Eat plenty of fruits and vegetables, avoid fried or fatty foods, drink lots of water, and get regular exercise.\nWhy Does Weight Matter?\nGaining too much or too little weight can have health implications for you and your baby.\nA very high pregnancy weight gain can increase your chances of having a big baby (10 pounds or more). It also increases your risk of developing pre-eclampsia (a type of high blood pressure) and of having a C-section. Not to mention, you\u2019ll be worried about shedding all that extra weight in a few more months.\nGaining too little weight can also be risky. This raises the risk of pre-term birth and a low-birth weight for your baby. Don\u2019t stress too much if you find you\u2019re not gaining a lot of weight in the first trimester because of nausea and vomiting. Just be sure to let your doctor know of your struggles so you can keep an eye on your health as your pregnancy progresses.\nHow Quickly Should I be Gaining Weight?\nMost pregnant women don\u2019t gain much in the first three months. In the second trimester, you start getting a nice bump, and the scale ticks higher. You\u2019ll probably average about a half pound to a pound per week in the second and third trimesters.\nIf you have a rapid weight gain, such as\u00a0three pounds in a week, you\u2019ll want to talk to your doctor right away. This can be a sign of pre-eclampsia.\nSometimes it\u2019s tough to see the scale move too much or not enough. Keep focused on making healthy choices, and you and your baby will be fine. Staying active now will also make it easier for you to get back into exercising to lose those extra pounds once your baby is here.\nFor more information on having a healthy pregnancy, visit the Magee-Womens Hospital of UPMC website.
