It certainly seems strange to lose weight when you’re creating a whole new person, but it’s probably nothing to fret about. Morning sickness and the accompanying loss of appetite can cause you to shed a few pounds in the first trimester. Don't worry — you'll more than make up for this loss in the upcoming months. And remember, most women only gain between two and five pounds in the first trimester.
Still, you can (and should) take action to ensure you and baby get the nutrients you need. Prenatal vitamins are the way to go,though you might want to ask your doctor about one with a low dose of iron (the mineral can actually make nausea worse). And, try to eat whenever you can stand it. An empty stomach can actually trigger nausea, as can low blood sugar,so eat before you are hungry and always keep snacks nearby. Getting extra sleep and cutting down the stress will also work wonders for your appetite.
For an alternative remedy, try ginger. (Ginger ale, ginger candies, ginger beef with snow peas…) It has a long history of making tummies feel better. Or slip on an acupressure band, found at most drugstores.The bands — meant to ward off seasickness —help many a mom fight the queasies. If you continue to lose weight or simply can’t keep anything down, talk with your doctor.
