Is it normal to lose weight during my first trimester?
I'm in my first trimester and losing weight. What's going on?

You expect the numbers on the scale to start creeping higher after you learn you're pregnant, so it's natural to worry if they're not. But losing weight in early pregnancy is actually pretty normal, especially if you've got a bad case of morning sickness. As many as 80 percent of moms-to-be experience some form of pregnancy nausea, which can make keeping even the blandest food down a real challenge -- resulting  in some looser-fitting jeans these days. Be assured that losing a few pounds at this stage has no impact on your baby's development. And to put things in perspective, you're not supposed to be gaining that much weight yet anyway! Normal-weight women shouldn't gain more than two to four pounds -- total -- in the entire first trimester. By week 14 or so, your morning sickness should subside and your appetite will likely return with a vengeance. At this point, the majority of women who lost weight early on quickly regain it -- and then some.

The only time weight loss is a problem is if it becomes significant, like more than 10 percent of your overall body weight -- a 150-pound woman dropping to less than 135 pounds, for example. If this happens, your doctor will likely prescribe medication to ease your morning sickness so you can eat again and start gaining weight healthfully.

I'll be 14 weeks in 2 days. My pre-pregnancy weight was 153. Now I'm down to 135. The doctors have given me some medication to help soothe the nausea and they're watching my weight loss.

No worries, as they say, everyone is different. I lost 10 pounds and didn't gain it back until I was out of my first trimester. Im now 21 weeks and weigh what I did before I got pregnant, and I wasn't overweight to start with(I had bad morning sickness till about week 17). All that matters is that your doctor knows whats going on and has checked you out.
