Pregnancy Weight Gain Guidelines by Week


Pregnancy Weight Gain Guidelines by Week
Most doctors will tell you that you should gain anywhere between 25-30 pounds through out your pregnancy. You should aim to limit weight gain to five pounds during your first trimester, although a lot of women find that they lose weight their first trimester due to morning sickness.

The First Twelve Weeks – First Trimester

Some women suffer from such a severe case of morning sickness they can not keep anything down. Chances are your doctor will not be too concerned if you lose a few pounds that first trimester as long as you gain steady throughout the next two trimesters.

The Second Trimester

Your second trimester is where you will probably put on most of your weight. Most women put on about a pound a week, so roughly four or five pounds a month which brings their second trimester weight gain to about 12-15 pounds. Some women put on more while others put on less. Do not be surprised if you put on a lot of weight one month and not so much your next.

Third Trimester

For the 7th and 8th month you will should probably continue about a pound each week or so. Look to gain between 8 and 10 pounds those months. Most women find that their weight gain slows down in the 9th month.

You might find your weight gain coming to a end as your due date draws nearer. This can be a sign that labor is on the horizon. Or, you may find that your weight gain continues especially if you are retaining a lot of water.

How It All Adds Up

So where does all this weight go? It doesn't really make sense that you should gain between 25-30 pounds if your baby is only going to weigh between 7 and 8 pounds. Let's break down where the extra weight goes.

  • An average baby weighs about 7 1/2 pounds.
  • The amniotic fluid weighs about 2 pounds.
  • About 2 pounds due to breast enlargement
  • 1 1/2 pounds for the placenta
  • Your uterus, which started off about the size of a golf ball has grown to weigh about 2 pounds
  • About 4 pounds of extra blood by the end of your pregnancy
  • About 7 extra pounds of fat
  • Extra fluid of about 4 pounds
  • All this equals to the grand total of about 30 pounds.

Now keep in mind this is just a estimate and not a guarantee of how your weight will fall. There are women who wind up having a 10 pound baby and others who have a 5 pound baby.

The key is to maintain a healthy pregnancy weight gain throughout. Your body needs extra calories and it is best for you and your baby if those extra calories come from food that has a lot of nutritional value such as fruits, vegetables or protein.

When it comes to taking the weight off, do not be surprised if your body hangs on to it especially those first days after delivery.
