Can My Morning Sickness Harm My Pregnancy?
Morning sickness feels terrible, but it happens to everybody (Well, almost everybody. About 90 percent of pregnant women experience some form of morning sickness or nausea). It's not harmful to the baby. In fact, it's not uncommon for women to actually lose weight during that first trimester, either because they're experiencing severe nausea and vomiting, or just because they can't seem to find any foods that taste good. For right now, just try to eat whatever you can, and as much as you can.
A very small percentage of women develop a condition called hyperemesis gravidarum, which is basically like morning sickness on steroids. If you are experiencing nausea so unbearable that you truly cannot keep anything down for days, or you develop dizziness or a fever, call your doctor. This condition puts you at risk of developing dehydration or an electrolyte imbalance, both of which can be dangerous for you and the baby.
