Healthy Pregnancy Weight Gain

Why do you gain weight?

 

What accounts for your weight gain during pregnancy? Your total weight gain is divided between the baby (including placenta and amniotic fluid) and your body (expanded blood volume, uterus growth and enlarged breasts). Normally there’s also a little maternal fat storage, which is essential for a healthy baby.

 

Here is an approximate breakdown of your healthy pregnancy weight gain:

 

Baby = 7 to 8 pounds

Placenta = 1 to 2 pounds

Amniotic fluid = 2 pounds

Uterus = 2 pounds

Maternal breast tissue = 2 pounds

Maternal blood = 4 pounds

Fluids in maternal tissue = 4 pounds

Maternal fat and nutrient stores = 7 pounds

 

 

How much should you gain?

 

During your first office visit, your doctor will discuss the expected body changes during pregnancy and estimate the right amount of weight for you to gain based on your health and your pre-pregnancy weight.

 

It’s recommended that most healthy women gain 25 to 35 pounds.

 

Trimester weight gain estimate

 

First: 1 to 1½ pounds a month

Second: About 1 pound a week

Third: About 1 pound a week

 

 

Getting it just right: healthy pregnancy weight gain

 

It’s really important to follow your doctor’s recommendation, because gaining either too little or too much during pregnancy can lead to difficulties.

 


Too little. Your little one needs nourishment, so you need to eat enough for both of you. If you don’t gain enough weight, she may have a low birth weight, and low-birth-weight babies have a harder time thriving and are more vulnerable to health problems.



Too much. Some women gain too much weight, even though they eat wisely, while some might use pregnancy as an excuse to break all their healthful eating rules. Before you break out the candy bars, remember that by gaining too much weight:

 

  • You put extra stress on your heart, which is already working overtime to pump your increased blood volume.
  • You add stress to your joints, which pregnancy hormones have loosened and made lax.
  • You’ll be more likely to develop backaches.

 

You’ll also make it extra hard to lose the weight after the baby arrives, and that extra weight can cause other health problems.

 

Chart your weight gain, month by month

 

One way to help monitor your weight gain is to chart your weight gain during pregnancy. Each month you can compare your own weight gain against the recommended weight gain noted above. Be sure to talk to your doctor about any questions or concerns you may have.

 

 

Benefits of prenatal exercise

 

In addition to managing weight and reducing stress, prenatal exercise can help prevent swollen ankles and varicose veins. Exercise increases your circulation, which helps draw off the extra fluid that can pool in your ankles and feet. Talk with your doctor to develop an exercise program that’s safe for you.
